The Future of NASA: Space Policy Issues Facing Congress
Summary
The National Aeronautics and Space Administration Authorization Act of 2010 (P.L. 111-267)
authorized major changes of direction for NASA. Among these, it called for the development of a
new, crew-capable, heavy-lift rocket, and it provided for the development of commercial services
to transport NASA crews into low Earth orbit. However, under the Continuing Appropriations
Act, 2011 (P.L. 111-242 as amended by P.L. 111-322), NASA continues to operate under a
requirement to proceed with its previous human spaceflight program. Moreover, in a period of
fiscal constraint, it is unclear whether future appropriations will match the growing NASA
budgets envisioned by the 2010 act. Thus the 112th Congress is likely to continue to closely
examine the future of NASA.
Before the 2010 act, NASA’s priorities were governed by the Vision for Space Exploration. The
Vision was announced by President Bush in January 2004 and endorsed by Congress in the 2005
and 2008 NASA authorization acts (P.L. 109-155 and P.L. 110-422). It directed NASA to focus its
efforts on returning humans to the Moon by 2020 and some day sending them to Mars and
“worlds beyond.” The resulting efforts are approaching major decision points, such as the end of
the space shuttle program and key milestones for the Constellation spacecraft development
program intended to replace the shuttle. A high-level independent review of the future of human
space flight, chaired by Norman R. Augustine, issued its final report in October 2009. It presented
several options as alternatives to the Vision and concluded that for human exploration to continue
“in any meaningful way,” NASA would require an additional $3 billion per year above previous
plans.
In February 2010, the Obama Administration proposed cancelling the Constellation program and
eliminating the goal of returning humans to the Moon. NASA would instead rely on commercial
providers to transport astronauts to Earth orbit, and its ultimate goal beyond Earth orbit would be
human exploration of Mars, with missions to other destinations, such as visiting an asteroid in
2025, as intermediate goals. Operation of the International Space Station would be extended to at
least 2020, and long-term technology development would receive increased emphasis. The 2010
authorization act incorporated many of these proposals, though it retained elements of
Constellation and scaled back the proposed emphasis on commercial providers and technology
development.
As the 112th Congress oversees NASA’s implementation of the 2010 act and considers how to
address the broad space policy challenges that remain, it faces questions about
•
whether NASA’s human exploration program is affordable and sufficiently safe,
and if so, what destination or destinations it should explore;
•
how to ensure that new spacecraft for human exploration, both governmentowned and commercial, are developed effectively, despite budget constraints;
•
how to manage the transition of workforce and facilities as the space shuttle
program comes to an end during 2011;
•
how best to manage and utilize the International Space Station; and
•
how NASA’s multiple objectives in human spaceflight, science, aeronautics, and
education should be prioritized.

The Future of NASA: Space Policy Issues Facing Congress
Introduction and Legislative Context
The idea of human spaceflight beyond Earth orbit has captivated many Americans for more than
half a century. As U.S. space policy has evolved, new opportunities have emerged, and new
challenges have arisen. From 2004 to 2010, the priorities of the National Aeronautics and Space
Administration (NASA) were governed by the Vision for Space Exploration. The Vision was
announced by President Bush in January 2004 and endorsed by Congress in the 2005 and 2008
NASA authorization acts (P.L. 109-155 and P.L. 110-422). It directed NASA to focus its efforts
on returning humans to the Moon by 2020 and some day sending them to Mars and “worlds
beyond.” The resulting efforts are now approaching major milestones, such as the end of the
space shuttle program and design review decisions for the new spacecraft intended to replace the
shuttle.
In May 2009, the Obama Administration announced plans for a high-level independent review of
the future of human space flight, chaired by Norman R. Augustine.1 Major components of the
FY2010 NASA budget request were placeholders, to be revised following the results of this
review. The Augustine committee released its final report in October 2009.2 The report identified
serious barriers to the implementation of the Vision and proposed several alternatives.
Committees in the House and Senate held hearings to consider the proposals.3 The Administration
did not submit a revised FY2010 budget for NASA. In December 2009, Congress appropriated
FY2010 funds for NASA at approximately the level in the President’s original request. The
appropriations conference report (H.Rept. 111-366) stated that the Augustine committee’s report
raises issues requiring thoughtful consideration by the Administration and the Congress.... It
is premature for the conferees to advocate or initiate significant changes to the current
program absent a bona fide proposal from the Administration and subsequent assessment,
consideration and enactment by Congress.... It is the expressed hope of the conferees that the
Administration will formulate its formal decision soon, submit its recommendations for
congressional review and consideration, and budget the necessary resources.
In February 2010, as part of its FY2011 budget, the Administration proposed major changes to the
Vision, including the elimination of a human return to the Moon as NASA’s primary goal, the
cancellation of NASA’s Constellation spacecraft development program, a new effort to encourage
the private sector to develop commercial crew launch services, and increased emphasis at NASA
on technology development and science. The 111th Congress considered these proposals but
ultimately did not pass a regular FY2011 appropriations bill for NASA. Under the Continuing
Appropriations Act, 2010 (P.L. 111-242 as amended by P.L. 111-322), NASA is operating at
FY2010 funding levels through March 4, 2011. Because the continuing resolution does not
explicitly remove it, a restriction in the FY2010 appropriations act that requires NASA to
continue the Constellation program remains in effect.

The Future of NASA: Space Policy Issues Facing Congress
The 111th Congress did pass a comprehensive NASA reauthorization bill, the NASA
Authorization Act of 2010 (P.L. 111-267). This act mandates several major changes in direction
for NASA. For example, it calls for the development of a new, crew-capable, heavy-lift rocket,
and it provides for the development of commercial services to transport NASA crews into low
Earth orbit. In the near term, NASA’s ability to implement these changes may be constrained by
operating under the continuing resolution.4 The NASA Inspector General has estimated that if the
continuing resolution is extended through the end of FY2011, without changes to the requirement
to continue Constellation, NASA will likely have to spend $575 million during FY2011 on
activities that it would otherwise no longer pursue.5 In the longer term, fiscal constraints may also
create barriers, if they result in future appropriations that do not match the growing NASA
budgets envisioned by the 2010 authorization act.
As Congress considers these broad space policy challenges, the major issues it faces can be
summarized as three broad questions:
•
What is NASA for? Different analysts and policy makers give different answers
to this question: making scientific discoveries, developing technologies with
economic benefits, enhancing national security, enhancing international prestige,
even fulfilling human destiny in space. How should these competing goals be
prioritized?
•
What should NASA do? In order to accomplish its broad goals, how should
NASA balance its major programs in human spaceflight, robotic spaceflight,
aeronautics research, and education? In the human spaceflight program, which is
larger than all the others put together, should the agency’s goal be exploration of
the Moon, Mars, or some other destination? What should the top priorities be for
NASA’s science and aeronautics programs?
•
How? Once these questions are decided, how should their answers be
implemented? What new space vehicles are needed? Should they be governmentowned or commercial? What should be done with existing programs, such as the
space shuttle and the International Space Station?
This report analyzes these questions and some possible answers. It also addresses a number of
cross-cutting issues, such as NASA’s interactions with other federal agencies and the growing role
of the commercial space industry.
What Is NASA For?
During the Eisenhower Administration, after the Soviet Union’s launch of the first artificial
satellite, Sputnik, but before the establishment of NASA, the President’s Science and Advisory
Committee identified four “principal reasons for undertaking a national space program”:

•
“the compelling urge of man to explore and to discover”;
•
“defense ... to be sure that space is not used to endanger our security ... [and to]
be prepared to use space to defend ourselves”;
•
to “enhance the prestige of the United States ... and create added confidence in
our scientific, technological, industrial, and military strength”; and
•
“scientific observation and experiment which will add to our knowledge and
understanding of the Earth, the solar system, and the universe.”6
To these objectives, analysts today add
•
the potential for technologies developed for the space program to have direct and
indirect (“spinoff”) economic benefits;
•
the opportunity to use space activities as a tool of international relations, through
collaboration on projects such as the International Space Station; and
•
the ability of the space program to inspire students and promote education in
science, technology, engineering, and mathematics (STEM).
These goals form a foundation for U.S. space policies, but policy makers differ in how they
should be balanced against each other. Is the urge to discover a sufficient reason to explore space,
or must exploration also meet needs here on Earth? Should economic benefits be an explicit focus
for NASA or just a positive side effect? To what extent should improving STEM education be a
NASA function, as opposed to a consequence of its other functions? Should the emphasis of
international space programs be competition or cooperation?
The priorities that Congress assigns to these objectives may determine how it balances the
competing demands of NASA’s programs. For example, if Congress believes that national
prestige is a high priority, it could choose to emphasize NASA’s high-profile human exploration
activities, such as exploring Mars or establishing a Moon base. If scientific knowledge is a high
priority, Congress could emphasize unmanned missions such as the Hubble telescope and the
Mars rovers. If international relations are a high priority, Congress could encourage joint space
activities with other nations. If economic benefits are of interest, Congress could focus on
technological development, linking NASA programs to the needs of business and industry.
A report by the National Academies proposed goals similar to those listed above and
recommended three criteria to use in balancing their competing demands for resources:7
•
Steady progress. Each major area should be maintained at a level that allows
sustained long-term progress with intermediate goals achieved at a reasonable
pace.

•
Stability. Rapid downsizing and abrupt redirection should be avoided because
they are disruptive, can take time to recover from, and can create risk as
operations experience is lost.
•
Robustness. Sufficient human resources and research infrastructure should be
maintained so that the nation can ramp up selected activities quickly in response
to changing national needs or scientific breakthroughs.
The Academies report did not, however, actually employ these criteria to prioritize the goals it
proposed.
What Should NASA Do?
Based on this wide variety of objectives, NASA has established programs in human spaceflight,
science, aeronautics, and education. The largest and most visible effort, in human spaceflight, has
faced considerable uncertainty about its proper scope and aims. The content of the science,
aeronautics, and education programs is less controversial but still faces questions about scope,
balance, and other issues.
Human Spaceflight: The Vision for Space Exploration
The Vision for Space Exploration, announced by President Bush in a speech on January 14, 2004,
directed NASA to focus its efforts on returning humans to the Moon by 2020 and eventually
sending them to Mars and “worlds beyond.”8 (Twelve U.S. astronauts walked on the Moon
between 1969 and 1972. No humans have visited Mars.) The Vision also directed NASA to return
the space shuttle to flight status following the February 2003 Columbia disaster; to complete
construction of the International Space Station (ISS) in accord with existing international
commitments; and to conclude U.S. participation in the ISS by the end of 2015. The first postColumbia shuttle flight was launched in July 2005. The other goals remain to be accomplished.
To advise NASA on implementation of the Vision, President Bush established a Commission on
the Implementation of U.S. Space Exploration Policy, chaired by Edward C. “Pete” Aldridge, Jr.9
The Aldridge Commission issued its report in June 2004.10 In April 2005, NASA established an
Exploration Systems Architecture Study (ESAS) to identify a strategy and technical architecture
for implementing the Vision. The ESAS issued its final report in November 2005.11 From then
until 2010, the reports of the Aldridge Commission and the ESAS were the baseline for NASA’s
space exploration plans.

The Future of NASA: Space Policy Issues Facing Congress
In the NASA Authorization Act of 2005 (P.L. 109-155), Congress endorsed the Vision in broad
terms and established several milestones for its implementation, including a statutory mandate to
return to the Moon no later than 2020.12 Nevertheless, it directed NASA to construct an
architecture and implementation plan for its human exploration program “that is not critically
dependent on the achievement of milestones by specific dates.”13
The NASA Authorization Act of 2008 (P.L. 110-422) reaffirmed the Vision’s broad goals,
including the “eventual” return to the Moon and missions to other destinations in the solar
system.14 It expressed the sense of Congress that “America’s friends and allies” should be invited
to participate.15 It directed NASA to take a “stepping stone approach” in which lunar exploration
activities are designed and implemented with strong consideration to their future contribution to
exploration beyond the Moon.16 It directed that plans for a lunar outpost should not require its
continuous occupation and that NASA should use commercial services for its lunar outpost
activities “to the maximum extent practicable.”17
Program to Implement the Vision
The program for implementing the Vision, as it stood before passage of the 2010 authorization
act, addressed the conclusion of the space shuttle and International Space Station programs as
well as the development and implementation of new vehicles for taking humans into Earth orbit
and then back to the Moon. The major elements were as follows:
•
Retire the space shuttle during 2011 (extended from the original deadline of the
end of 2010). Rely on non-U.S. vehicles for human access to space until a
replacement vehicle is developed.
•
Terminate U.S. use of the International Space Station at the end of 2015.
•
Under the Constellation program, develop new systems for space exploration:
•
the Ares I rocket to launch astronauts into low Earth orbit, where the
International Space Station is located;
•
the Orion crew capsule, to be launched atop Ares I to carry astronauts into
orbit and beyond;
•
the Ares V heavy-lift rocket to send astronauts and equipment to the Moon;
and
•
the Altair lunar lander and various lunar surface systems.
Before the Administration’s FY2011 budget proposals, no funds were projected for any shuttle
flights after the end of 2010. No FY2016 funds were projected for deorbiting the space station.
The first crewed flight (or “initial operating capability”) of Ares I and Orion was scheduled for

early 2015. The first return to the Moon, using all the Constellation systems together, was planned
for 2020, although NASA acknowledged that meeting that date would be difficult.
The 2010 authorization act extended U.S. use of the International Space Station through at least
2020 and replaced Constellation with programs to develop commercial services for launching
astronauts into low Earth orbit (instead of Ares I); a multipurpose crew vehicle (similar to Orion);
and a new heavy-lift rocket (possibly similar to Ares V). The transition from Constellation to
these new programs, however, is constrained while NASA operates under the continuing
resolution.
Issue for Congress: Cost and Schedule
Cost played a central role as congressional policy makers oversaw the Vision’s progress and
considered proposals to modify it. During the Bush Administration, NASA stressed that its
strategy was to “go as we can afford to pay,” with the pace of the program set, in part, by the
available funding.18 The original plan in 2004 proposed adding a total of just $1 billion to
NASA’s budget for FY2005 through FY2009 to help pay for the Vision, with increases thereafter
limited to the rate of inflation. Subsequent Administration budgets more than eliminated this
increase, and actual appropriations by Congress were even less. As a result, most funding for the
Vision has been redirected from other NASA activities, such as the planned termination of the
space shuttle program.
NASA has not provided a cost estimate for the Vision as a whole. In 2004, it projected that
developing capabilities for human exploration, not including robotic support missions, would cost
a total of $64 billion up through the first human return to the Moon.19 The Congressional Budget
Office (CBO) concluded that, based on historical trends, the actual cost could be much higher.20
In its 2005 implementation plan, NASA estimated that returning astronauts to the Moon would
cost $104 billion, not including the cost of robotic precursor missions or the cost of servicing the
ISS after the end of the shuttle program.21 In 2007, the Government Accountability Office (GAO)
estimated the total cost for the Vision as $230 billion over two decades.22 In April 2009, as
directed in the 2008 authorization act, the CBO updated its 2004 budgetary analysis of the Vision.
It found that NASA would need an additional $2 billion per year through FY2025 to keep the
Vision activities on schedule, not counting probable cost growth in other activities.23 In October
2009, the Augustine report stated that executing NASA’s plans would require an additional $3
billion per year, even with some schedule delays.24

The Future of NASA: Space Policy Issues Facing Congress
Schedule is closely related to cost. For example, the 2009 CBO analysis found that NASA could
maintain its currently planned budget by delaying its return to the Moon by approximately three
years.25 The tradeoffs can be difficult to quantify, however. The Augustine report, unlike the CBO
analysis, found that under NASA’s budget plans at the time of the report, “human exploration
beyond low-Earth orbit is not viable” and planned budgets would delay a return to the Moon
“well into the 2030s, if ever.”26 Schedule delays were already evident. For example, the initial
operating capability for Orion and Ares I, originally planned for 2012, had slipped to 2015; the
Augustine committee concluded that 2017 was more likely.
Issue for Congress: Why the Moon?
Ever since the Vision was announced, some analysts questioned its choice of the Moon as the
headline destination for NASA’s human exploration efforts. Some felt that revisiting the
destination of the Apollo missions of 1969-1972 was a less inspiring goal than a new target would
be.27 Some doubted the scientific rationale, suggesting that robotic missions to the Moon could
accomplish as much or more at lower cost and without risking human lives, or that more could be
learned by visiting another destination that has been studied less by previous missions. Some
were simply concerned about the cost.
Supporters countered that the Moon is the closest destination beyond Earth orbit and could serve
as a stepping stone for subsequent destinations. As Earth’s nearest neighbor, the Moon is of great
scientific interest. Missions to the Moon would provide an opportunity to develop and test
technologies and gain experience working in space. According to some advocates, the Moon
might literally be a staging point for future missions. For some in Congress, concerned about
national security or national prestige, the prospect of a manned Chinese mission to the Moon was
a strong motivation to reestablish a U.S. presence. For many who supported the Vision,
completing it became important in itself; part of the Vision’s original purpose was to set a goal for
NASA that would give the agency direction and enhance its public support, and some supporters
feared that changing the plan would weaken NASA, whether or not a better plan could be
devised.
Issue for Congress: “The Gap” and Utilization of the Space Station
In order to fund the cost of the Vision and because of safety concerns following the Columbia
disaster in 2003, NASA intended to end the space shuttle program in 2010 once construction of
the ISS was complete. (Because of schedule delays and a congressional mandate for an additional
flight, the program will end during 2011 rather than 2010.) The shuttle’s successors, Orion and
Ares I, were not expected to be ready for crewed flight until at least 2015. The difference between
these dates is generally referred to as “the gap.” Congressional policy makers and others

The Future of NASA: Space Policy Issues Facing Congress
expressed concerns about U.S. access to space during the gap. The NASA Authorization Act of
2005 declared it to be U.S. policy “to possess the capability for human access to space on a
continuous basis.”28 Former NASA Administrator Michael Griffin, a strong advocate of the
Vision, referred to the gap as “unseemly in the extreme.”29
Under current plans, Russian spacecraft will be the only means of access to the ISS for humans
during the gap. A variety of alternatives are being considered for cargo. These points are
discussed further below in the section “Post-Shuttle Access to the ISS.” The prospect of the gap
has intensified congressional concerns about whether the capabilities of the ISS will be fully
utilized.
Human Spaceflight: The Augustine Committee
The Review of U.S. Human Spaceflight Plans Committee was formally chartered on June 1,
2009. It was chaired by Norman R. Augustine, a former chairman and chief executive officer of
Lockheed Martin Corporation and a member of the President’s Council of Advisors on Science
and Technology under Presidents of both parties. Other committee members included scientists,
engineers, astronauts, educators, executives of established and new aerospace firms, former
presidential appointees, and a retired Air Force general.30 The committee reported jointly to the
Administrator of NASA and the Director of the Office of Science and Technology Policy in the
Executive Office of the President. The committee’s charter defined its scope and objectives as
follows:31
The Committee shall conduct an independent review of ongoing U.S. human space flight
plans and programs, as well as alternatives, to ensure the Nation is pursuing the best
trajectory for the future of human space flight – one that is safe, innovative, affordable, and
sustainable. The Committee should aim to identify and characterize a range of options that
spans the reasonable possibilities for continuation of U.S. human space flight activities
beyond retirement of the Space Shuttle. The identification and characterization of these
options should address the following objectives: a) expediting a new U.S. capability to
support utilization of the International Space Station (ISS); b) supporting missions to the
Moon and other destinations beyond low-Earth orbit (LEO); c) stimulating commercial space
flight capability; and d) fitting within the current budget profile for NASA exploration
activities.32
In addition to the objectives described above, the review should examine the appropriate
amount of research and development and complementary robotic activities needed to make
human space flight activities most productive and affordable over the long term, as well as
appropriate opportunities for international collaboration. It should also evaluate what

capabilities would be enabled by each of the potential architectures considered. It should
evaluate options for extending ISS operations beyond 2016.
Options Identified by the Augustine Committee
The committee released its final report in October 2009. It identified five options: two within the
existing budget profile and three that would require about an additional $3 billion per year. In the
committee’s judgment, developing Ares I, Orion, and the other Constellation systems is likely to
take longer than NASA currently plans, and the options presented by the committee reflect these
expected delays. The options are as follows:33
•
Option 1: Current Budget, Current Program. This option is the current
program, modified only to provide funds for space shuttle flights in FY2011 and
for deorbiting the International Space Station in FY2016. The first crewed flight
of Ares I and Orion is no earlier than 2017, after the International Space Station
has been deorbited. Ares V is not available until the late 2020s, and there are
insufficient funds to develop Altair and the lunar surface systems needed for
returning to the Moon until well into the 2030s, if ever.
•
Option 2: Current Budget, Extend Space Station, Explore Moon Using
Ares V Lite. This option extends use of the International Space Station to 2020
and begins a program of lunar exploration using a variant of Ares V known as
Ares V Lite. It develops commercial services to transport humans into low Earth
orbit. It delivers a heavy-lift capability in the late 2020s, but it does not develop
the other systems needed for returning to the Moon for at least the next two
decades.
•
Option 3: Additional Budget, Current Program. Like Option 1, this option is
the current program, modified to provide funds for space shuttle flights in
FY2011 and to deorbit the International Space Station in FY2016. The first
crewed flight of Ares I and Orion would still be after the International Space
Station is deorbited. The additional funding, however, would permit a human
lunar return in the mid-2020s.
•
Option 4: Additional Budget, Extend Space Station, Explore Moon First.
Like Option 2, this option extends use of the International Space Station to 2020
and uses commercial services to transport humans into low Earth orbit. The first
destination beyond Earth orbit is still the Moon. There are two variants to this
option. Variant 4A develops the Ares V Lite for lunar exploration as in Option 2.
Variant 4B extends the space shuttle program to 2015 and develops a heavy-lift
vehicle for lunar missions that is more directly shuttle-derived. Both variants
permit a human lunar return by the mid-2020s.
•
Option 5: Additional Budget, Extend Space Station, Flexible Path for
Exploration. Like Option 4, this option extends use of the International Space
Station to 2020 and uses commercial services to transport humans into low Earth
orbit. Missions beyond Earth orbit, however, follow a “flexible path” of
increasingly distant destinations—such as lunar fly-bys, rendezvous with
33

Nation, pp. 15-16.

The Future of NASA: Space Policy Issues Facing Congress
asteroids and comets, and Mars fly-bys—without initially attempting a lunar
landing. A lunar landing would be possible by the mid to late 2020s. Variant 5A
employs the Ares V Lite. Variant 5B uses a commercial heavy-lift rocket derived
from the Evolved Expendable Launch Vehicle (EELV). Variant 5C develops a
shuttle-derived vehicle for heavy lift as in Variant 4B. (These alternative launch
vehicles are discussed further later in this report.)
Although the committee’s report did not recommend any particular one of these options, it made a
number of findings and comments that put the options into context:34
•
Option 1 and Option 2 fit within the current budget profile, but “neither allows
for a viable exploration program. In fact, the Committee finds that no plan
compatible with the FY2010 budget profile permits human exploration to
continue in any meaningful way.” The additional funding contemplated in
Options 3, 4, and 5 is necessary for “an exploration program that will be a source
of pride for the nation.”
•
“The return on investment to both the United States and our international partners
would be significantly enhanced by an extension of the life of the [International
Space Station]. A decision not to extend its operation would significantly impair
U.S. ability to develop and lead future international spaceflight partnerships.”
•
Commercial services to launch crews into Earth orbit “are within reach. While
this presents some risk, it could provide an earlier capability at lower initial and
life-cycle costs than the government could achieve.”
•
Of the heavy-lift alternatives, Ares V Lite is “the most capable.” The commercial
EELV derivative “has an advantage of potentially lower operating costs, but
requires significant restructuring of NASA” including “a different (and
significantly reduced) role.” A shuttle-derived vehicle would “take maximum
advantage of existing infrastructure, facilities, and production capabilities.”
•
Variant 4B, which extends operation of the space shuttle to 2015, is “the only
foreseeable way to eliminate the gap in U.S. human-launch capability.”
•
“Mars is the ultimate destination for human exploration of the inner solar system;
but it is not the best first destination. Visiting the ‘Moon First’ and following the
‘Flexible Path’ are both viable exploration strategies. The two are not necessarily
mutually exclusive; before traveling to Mars, we could extend our presence in
free space and gain experience working on the lunar surface.”
Questions for Congressional Policy Makers to Consider
The Augustine committee identified five questions “that could form the basis of a plan for U.S.
human spaceflight”:35

What should be the future of the space shuttle?

The Future of NASA: Space Policy Issues Facing Congress
•
What should be the future of the International Space Station?
•
On what should the next heavy-lift launch vehicle be based?
•
How should crew be carried to low Earth orbit?
•
What is the most practicable strategy for exploration beyond low Earth orbit?
These five questions focus on designing a future program of human spaceflight. In keeping with
the committee’s charter, the questions do not address NASA’s other programs, and they take it as
given that a human spaceflight program should be implemented. Congress may therefore wish to
consider additional questions such as these:
•
Is human spaceflight beyond low Earth orbit worth the cost and risk?
•
If not, are there alternatives that would accomplish some of the same goals?
•
What is the future of NASA’s other activities, such as robotic exploration,
science, and aeronautics research?
Each of these issues is discussed in more detail later in this report.
Human Spaceflight: Administration Proposals
In its FY2011 budget request, the Obama Administration proposed cancelling the Constellation
program and eliminating the return of humans to the Moon as NASA’s primary goal.36 Instead,
NASA would encourage the private sector to develop commercial space transportation services to
carry astronauts to and from the International Space Station. For spaceflight beyond Earth orbit,
NASA would emphasize long-term technology development rather than near-term development
of specific flight systems. Operation of the International Space Station would continue until at
least 2020. When asked about destinations for future human exploration of space, NASA officials
stated that Mars would be the ultimate goal, but that other intermediate destinations would come
first. They described these proposals as consistent with the “Flexible Path” option identified by
the Augustine committee.
Congressional and Public Reaction
For the most part, Congress and the public at large reacted negatively to the Administration’s
proposals. Their concerns included the potential negative impact of Constellation’s cancellation
on employment in the aerospace industry, the lack of a specific destination and schedule to
replace the goal of returning humans to the Moon, and the risk that the private sector might not in
fact develop commercial space transportation services that meet NASA’s needs. In the media,
attention focused on the proposed cancellation of Constellation, with less notice of the programs
that would replace it, such as increased technology development and stimulation of commercial
space transportation services. Press accounts often reported the Administration’s proposals as
cutting NASA’s budget, or eliminating its human spaceflight program, even though the proposed
FY2011 budget for NASA was actually an increase over previous plans and included other human
spaceflight activities to replace Constellation.

Congressional Research Service
11
The Future of NASA: Space Policy Issues Facing Congress
Supporters of Constellation were particularly concerned about its status during FY2010. The
FY2010 appropriations act prohibited NASA from using FY2010 or prior-year funds to terminate
or eliminate “any program, project, or activity of the architecture for the Constellation program”
or to create or initiate any new program, project, or activity.37 Some analysts and policy makers
expressed concern that NASA’s contracting decisions and other actions during FY2010 violated
this provision.38 NASA officials replied that they were continuing to implement the Constellation
program during FY2010 in full compliance with the law, even though they intended to terminate
the program in FY2011. Two GAO opinions in May and July 2010 concluded that NASA had not
violated the appropriations provision.39 In June 2010, NASA announced that it would “prioritize”
and “pace” (but not “terminate”) contracts in the Constellation program because contract
termination liabilities could result in a $1 billion “shortfall” in the program’s FY2010 funding.40
Modifications to the Administration Proposals
On April 15, 2010, President Obama gave a speech at the Kennedy Space Center in Florida that
attempted to answer some of these public and congressional concerns.41 In this speech, he
announced several modifications to the original FY2011 budget request proposals:
•
Development of a modified Orion crew capsule would continue. The modified
design would provide an emergency escape capability for the International Space
Station, however, rather than transporting crews to and from the station on a
regular basis.
•
The next human mission beyond Earth orbit would be to an asteroid and would
take place in 2025. This would be the first human mission to a destination more
distant than the Moon. Subsequent missions to orbit Mars would take place in the
mid-2030s. A human landing on Mars would remain the ultimate goal.
•
NASA’s increased technology efforts would focus on the development of a new
heavy-lift rocket, with a decision in 2015 on a specific heavy-lift architecture for
exploration of deep space.
•
Independent of the FY2011 budget, an Administration task force will address
economic development and the aerospace industry in the region of Florida known
as the Space Coast.

The Future of NASA: Space Policy Issues Facing Congress
An Administration budget amendment in June 2010 proposed transferring $100 million from the
Exploration account in NASA’s FY2011 budget request to the Departments of Commerce and
Labor “to spur regional economic growth and job creation along the Florida Space Coast and
other affected regions.”42
Human Spaceflight: The 2010 Authorization Act
In October 2010, Congress passed the NASA Authorization Act of 2010 (P.L. 111-267). The act
authorizes funding for NASA for FY2011 through FY2013 at a level that matches the
Administration’s proposals. Its allocation of those funds within the agency, however, is quite
different. New efforts in long-term space technology development are reduced by about half. This
allows the addition of one extra space shuttle flight in FY2011 and additional funding for other
human spaceflight programs in subsequent years. The human spaceflight program is to retain the
full Orion crew capsule and develop a new, crew-capable, heavy-lift rocket. To pay for Orion and
the new rocket, other elements of the human spaceflight program are to be scaled back
significantly, including the Administration’s proposals for technology demonstrations, robotic
precursor missions, and development of commercial crew launch services.
As with any authorization act, these budgetary plans are subject to subsequent appropriations by
Congress. Because the 111th Congress did not pass a regular FY2011 appropriations act for
NASA, the 112th Congress will determine appropriations for all three years covered by the 2010
authorization act.
Other provisions of the NASA Authorization Act of 2010 are discussed throughout this report
together with related discussion of the topics addressed.
Science
About two-thirds of NASA’s budget is associated with human spaceflight. Most of the rest is
devoted to unmanned science missions. These science missions fall into four categories: Earth
science, planetary science, heliophysics, and astrophysics. The latter three are sometimes known
collectively as space science.
In part because of concerns about climate change, both Congress and the Administration have
recently placed increased emphasis on Earth science. In the FY2006 and FY2007 budget cycles
NASA had no separate budget for Earth science, and supporters became concerned that this was
adversely affecting the field. In late 2006, NASA reorganized the Science Mission Directorate,
creating a separate Earth Science Division. The National Research Council recommended in early
2007 that the United States “should renew its investment in Earth observing systems and restore
its leadership in Earth science and applications.”43 In response, Congress and the Administration
increased the share of NASA’s science funding devoted to Earth science from 26% in FY2008 to
32% in FY2010. In addition, NASA allocated 81% of the science funding it received under the
American Recovery and Reinvestment Act of 2009 (P.L. 111-5) to Earth science. The
Administration’s requested budget for FY2011 would provide substantial increases for Earth

science funding, including a five-year, $2.1 billion global climate initiative. For FY2011 through
FY2013, the NASA Authorization Act of 2010 authorized these increases.44
In recent years, Congress has sought to ensure that NASA’s science program includes a balanced
variety of approaches to R&D rather than focusing only on certain types of missions. For
example, the NASA Authorization Act of 2008 stated that the science program should include
space science missions of all sizes as well as mission-enabling activities such as technology
development, suborbital research, and research and analysis (R&A) grants to individual
investigators.45 According to the National Research Council, “practically all relevant external
advisory reports have emphasized the importance of mission-enabling activities,” but determining
their proper scale has been challenging “throughout NASA’s history.”46 In the past few years,
funding for planetary science technology has increased significantly, but funding for Earth
science technology has increased only slightly; the astrophysics and heliophysics programs do not
have dedicated technology subprograms. Funding for suborbital rocket operations increased from
$51 million in FY2008 to $66 million in FY2010, but the trend is unclear as the latter amount was
down from $77 million in FY2009.47 Funding for R&A grants, which NASA controversially
proposed to reduce significantly as recently as FY2007, has recovered as the result partly of the
Administration’s own initiatives and partly of congressional action on appropriations legislation.
The NASA Authorization Act of 2010 reaffirmed the sense of Congress that “a balanced and
adequately funded set of activities, consisting of research and analysis grants programs,
technology development, small, medium, and large space missions, and suborbital research
activities, contributes to a robust and productive science program and serves as a catalyst for
innovation.”48
In December 2009, the National Research Council recommended ways to make the missionenabling activities of NASA’s science programs more effective through more active management.
These recommendations included establishing explicit objectives and metrics, making budgets
more transparent, and clearly articulating the relationships between mission-enabling activities
and the ensemble of missions they are intended to support.49 The NASA Authorization Act of
2008 stated that the technology development program should include long-term activities that are
“independent of the flight projects under development.”50 NASA may sometimes find it
challenging to balance this independence against the goal of linking mission-enabling activities to
the missions they support.
NASA’s science programs have a history of periodic review by the National Academies. Such
reviews typically take place every 10 years, so they are commonly known as decadal surveys.
The NASA Authorization Act of 2005 mandated an Academy review of each division of NASA’s

science directorate every five years.51 The NASA Authorization Act of 2008 also mandated
periodic reviews and directed that they include independent estimates of the cost and technical
readiness of each mission assessed.52 The NASA Authorization Act of 2010 directed NASA to
“implement, as appropriate ... within the scope of the funds authorized,” the missions identified
by the Earth science decadal survey, and to “take into account” space science decadal surveys
when submitting the President’s annual budget request.53 Decadal surveys by the National
Academies are generally well received by NASA and are widely respected in the science and
science policy communities. On the other hand, the expertise of the National Academies is
primarily scientific. It is unclear whether their analysis of mission cost and readiness will be
considered equally authoritative.
Aeronautics
After human spaceflight and science, NASA’s largest activity is research on aeronautics, the
science and technology of flight within Earth’s atmosphere. There is a history of disagreement in
Congress about the appropriate role of this program. Supporters argue that the aviation industry is
vital to the economy, especially because aircraft are a major component of U.S. exports. They
claim that government funding for aeronautics research can contribute to U.S. competitiveness
and is necessary in light of similar programs in Europe and elsewhere.54 Opponents counter that
the aviation industry itself should pay for the R&D it needs. Against the background of this
debate, NASA aeronautics programs have focused increasingly on long-term fundamental R&D
and on research topics with clear public purposes, such as reducing noise and emissions,
improving safety, and improving air traffic control.
In 2005, Congress directed the President to develop a national policy for aeronautics R&D.55 The
National Science and Technology Council (NSTC), part of the Executive Office of the President,
issued this policy in December 2006.56 The policy established general principles and goals for
federal aeronautics activities, laid out the roles and responsibilities of NASA and other agencies,
and directed the NSTC to issue a national aeronautics R&D plan at least every two years. The
NSTC released the first national aeronautics R&D plan in December 2007 and the second in
February 2010.57 The NASA Authorization Act of 2008 stated that NASA’s aeronautics research
program should be “guided by and consistent with” the national aeronautics R&D policy.58

tecop_europe_aero_r&d.pdf.) The report also found that European aeronautics R&D was increasingly guided by a 2001
European Union report that called for European countries to invest about $100 billion in the topic over 20 years. See

The Future of NASA: Space Policy Issues Facing Congress
In June 2006, in response to a congressional mandate, the National Research Council of the
National Academies released a decadal strategy for federal civil aeronautics activities, with a
particular emphasis on NASA’s aeronautics research program.59 Along with other
recommendations, the report identified 51 technology challenges to serve as the foundation for
aeronautics research at NASA for the next decade. In the 2008 authorization act, Congress
directed NASA to align its fundamental aeronautics research program with these technology
challenges “to the maximum extent practicable within available funding” and to increase the
involvement of universities and other external organizations in that program.60 It also mandated
periodic Academy reviews of the NASA aeronautics program and directed that they include
independent estimates of the cost and technical readiness of each mission assessed.61 As noted
above with respect to its decadal surveys of NASA science, while the National Academies are
widely respected for their scientific expertise, it is unclear whether their analysis of cost and
technical readiness will be considered equally authoritative.
The aeronautics program’s heavy use of shared facilities and capabilities, such as wind tunnels
and supercomputers, has sometimes created challenges. For example, when NASA introduced
full-cost accounting in the FY2004 budget request, the stated cost of the aeronautics program
increased significantly because facility costs had previously been budgeted in another account. At
least partly in response to these concerns, NASA subsequently established a separate Aeronautics
Test Program in the aeronautics directorate and a Strategic Capabilities Assets Program outside
the directorate. It has also sometimes been difficult for NASA to balance its stewardship of
unique aeronautics facilities, often used by other agencies and by industry as well as by NASA
itself, against the cost of maintaining those facilities. In 2005, Congress directed NASA to
establish a separate account to fund aeronautics test facilities, to charge users of NASA test
facilities at a rate competitive with alternative facilities, and not to implement a policy seeking
full cost recovery for a facility without giving 30 days’ notice to Congress.62 To accompany the
national aeronautics R&D plan, the Aeronautics Science and Technology Subcommittee of the
NSTC developed a national aeronautics research, development, test, and evaluation infrastructure
plan.63 The infrastructure plan will be updated periodically in response to the biennial updates of
the R&D plan.64
There is ongoing congressional interest in the relationship between NASA’s aeronautics program
and related efforts by the Federal Aviation Administration (FAA) and the Department of Defense
(DOD). One aspect of this relationship is the interagency Joint Planning and Development Office
(JPDO), which oversees the development of a Next Generation Air Transportation System

(NGATS) for improved airspace management.65 Congress has directed NASA to align the
Airspace Systems program of its Aeronautics Research Directorate with the objectives of the
JPDO and NGATS.66 The NASA Authorization Act of 2010 directed NASA to continue to
coordinate its aeronautics research with DOD and the FAA.67
Education
In 2008, a congressionally mandated National Academies review of NASA education programs
found that even though NASA is uniquely positioned to interest students in science, technology,
and engineering, its education programs are not as effective as they could be.68 The report found
that NASA has no coherent plan to evaluate its education programs, and few of them have ever
been formally evaluated. It recommended that NASA develop an evaluation plan and use the
results of the evaluations to inform project design and improvement. It found that the operating
directorates, rather than the Office of Education, fund about half of the agency’s primary and
secondary education activities. It recommended that the Office of Education focus on
coordination and oversight, including advocacy for the inclusion of education activities in the
programs of the operating directorates. Congress directed NASA to prepare a plan in response to
the recommendations of the National Academies, including a schedule and budget for any actions
that have not yet been implemented.69 NASA issued this plan in January 2010.70 In the NASA
Authorization Act of 2010, Congress directed NASA to submit a report on outcomes of its
education programs.71
Unlike the Department of Education or the National Science Foundation, NASA does not have a
lead role in federal education programs. As a result, some analysts may view NASA’s education
activities as secondary to its primary efforts in spaceflight, science, and aeronautics. Congress,
however, is typically supportive of NASA education programs and often provides more funding
for them than NASA requests. This imbalance between Administration and congressional
priorities, the dispersed nature of NASA’s education activities outside the Office of Education,
and the tendency for congressional funding increases to be dedicated to specific one-time projects
rather than to ongoing programs, may make it difficult for NASA to plan and manage a coherent,
unified education program.
Balancing Competing Priorities
Ever since the announcement of the Vision, NASA’s emphasis on exploration has created
concerns about the balance between human spaceflight and NASA’s other activities, especially

science and aeronautics. Because most funding for the Vision has been redirected from other
NASA activities, advocates of science and aeronautics have feared that their programs will be cut
in order to pay for human exploration activities. Congress, while fully supporting the Vision, has
been clear about the need for balance. The NASA Authorization Act of 2005 directed NASA to
carry out “a balanced set of programs,” including human space flight in accordance with the
Vision, but also aeronautics R&D and scientific research, the latter to include robotic missions
and research not directly related to human exploration.72 The NASA Authorization Act of 2008
found that NASA “is and should remain a multimission agency with a balanced and robust set of
core missions in science, aeronautics, and human space flight and exploration” and “encouraged”
NASA to coordinate its exploration activities with its science activities.73 In January 2010, NASA
Administrator Charles Bolden assured a group of scientists that “the future of human spaceflight
will not be paid for out of the hide of our science budget.”74
Balancing these competing priorities depends on answering questions, raised earlier in this report,
about NASA’s purpose. More than 50 years ago, President Eisenhower’s advisors were aware that
a space program was justified both by “the compelling urge of man to explore and to discover”
and by “scientific observation and experiment which will to add to our knowledge and
understanding.” Today, there is still no consensus about how to balance these purposes. Some
policy makers believe that a space program can best be justified by tangible benefits to economic
growth and competitiveness. Others believe that its most important role is to be a source of
national pride, prestige, and inspiration.
Space Shuttle Program
Since its first launch in April 1981, the space shuttle has been the only U.S. vehicle capable of
carrying humans into space. After a few remaining flights during 2011, the space shuttle program
is scheduled to end. Although some advocates and policy makers would like to extend the
program, technical and management issues are making that ever more difficult as the scheduled
termination approaches. Congress’s attention is increasingly on managing the transition of the
shuttle workforce and facilities and on addressing the projected multi-year gap in U.S. access to
space between the last shuttle flight and the first flight of its successor.
Why the Shuttle Program Is Ending
The oldest shuttle is approaching 30 years old; the youngest is approaching 20. Although many
shuttle components have been refurbished and upgraded, the shuttles as a whole are aging
systems. Most analysts consider the shuttle design to be based, in many respects, on obsolete or
obsolescent technology. The original concept of the shuttle program was that a reusable launch
vehicle would be more cost-effective than an expendable one, but many of the projected cost
savings depended on a flight rate that has never been achieved.

The Future of NASA: Space Policy Issues Facing Congress
Over the years, NASA has attempted repeatedly, but unsuccessfully, to develop a secondgeneration reusable launch vehicle to replace the shuttle. In 2002, NASA indicated that the shuttle
would continue flying until at least 2015 and perhaps until 2020 or beyond. The Columbia
disaster in 2003 forced NASA to revise that plan.
Within hours of the loss of the space shuttle Columbia and its seven astronauts, NASA
established the Columbia Accident Investigation Board to determine the causes of the accident
and make recommendations for how to proceed.75 The board concluded that the shuttle “is not
inherently unsafe” but that several actions were necessary “to make the vehicle safe enough to
operate in the coming years.”76 It recommended 15 specific actions to be taken before returning
the shuttle to flight. In addition, it found that
because of the risks inherent in the original design of the space shuttle, because the design
was based in many aspects on now-obsolete technologies, and because the shuttle is now an
aging system but still developmental in character, it is in the nation’s interest to replace the
shuttle as soon as possible as the primary means for transporting humans to and from Earth
orbit.77
The board recommended that if the shuttle is to be flown past 2010, NASA should “develop and
conduct a vehicle recertification at the material, component, subsystem, and system levels” as
part of a broader and “essential” Service Life Extension Program.78
The announcement of the Vision for Space Exploration in 2004 created another reason to end the
shuttle program: money. Before the shuttle program began to ramp down, it accounted for about
25% of NASA’s budget. Making those funds available for the Vision became a primary
motivation for ending the program.
Possible Extension of the Shuttle Program
Despite the safety risks identified by the Columbia Accident Investigation Board and the need to
reallocate the shuttle’s funding stream to other purposes, some policy makers and advocates
remain eager to extend the program. For example, the NASA Authorization Act of 2008 directed
NASA not to take any action that would preclude a decision to extend the shuttle program past
2010.79 One of the options put forward by the Augustine committee (Variant 4B) included
extending the shuttle program to 2015. The NASA Authorization Act of 2010 provided for an
additional shuttle flight no earlier than June 1, 2011, and directed NASA to preserve its capability
to launch space shuttles through FY2011.80
A decision to extend the program would create challenges relating to cost, schedule, and safety.
With the planned termination date approaching, some contracts for shuttle components have

already run out, and some contractor personnel have already been let go.81 Reestablishing the
capability to operate the program would likely incur costs and delays, and this potential will grow
as the planned termination date approaches. The recertification process recommended by the
Columbia Accident Investigation Board could be costly and time-consuming, although the board
itself gave no estimate of either cost or schedule. At this point, completing a recertification in
time to maintain a continuous flight schedule might already be difficult. Congressional policy
makers or the Administration could simply decide to continue flying anyway, in parallel with the
recertification process—in effect, NASA has already done this to some extent with the decision to
allow a few flights originally planned for 2010 to slip into 2011—but policy makers might suffer
political repercussions from such a choice if another serious accident occurred.
During the 2009 presidential transition, the GAO identified the pending retirement of the space
shuttle in 2010 as one of 13 “urgent issues” facing the incoming Obama Administration.82 The
GAO also stated that “according to NASA, reversing current plans and keeping the shuttle flying
past 2010 would cost $2.5 billion to $4 billion per year.”83
Transition of Shuttle Workforce and Facilities
The transition of assets and personnel at the end of the shuttle program is of great interest to many
in Congress and represents a major challenge for NASA. The shuttle workforce is a reservoir of
unique expertise and experience that would be difficult for NASA and its contractors to
reassemble once dispersed. NASA managers are particularly concerned to maintain key human
spaceflight expertise and capabilities. In certain communities, the loss of the shuttle workforce
will have a significant economic impact. For individuals, the loss of specialized, well-paid
employment that has been relatively stable for many years can be especially disruptive at a time
when the job market is already unusually difficult. Finding the best alternative use of facilities
and equipment is important for getting the best value for the taxpayer.
NASA’s transition management plan, issued in August 2008, establishes a timeline for the postshuttle transition, defines organizational responsibilities for various aspects of the transition,
establishes goals and objectives, and outlines planning and management challenges such as
management of human capital and disposition of infrastructure.84 As it notes, the scope of the
transition is huge:
The SSP [space shuttle program] has an extensive array of assets; the program occupies over
654 facilities, uses over 1.2 million line items of hardware and equipment, and employs over
2,000 civil servants, with more than 15,000 work year equivalent personnel employed by the
contractors. In addition, the SSP employs over 3,000 additional indirect workers through
Center Management and Operations and service accounts. The total equipment acquisition
value is over $12 billion, spread across hundreds of locations. The total facilities replacement
cost is approximately $5.7 billion, which accounts for approximately one-fourth of the value

of the Agency’s total facility inventory. There are over 1,200 active suppliers and 3,000 to
4,000 qualified suppliers geographically located throughout the country.85
Congress has addressed a number of these issues through legislation:
•
In the NASA Authorization Act of 2005, Congress directed NASA to use the
personnel, capabilities, assets, and infrastructure of the shuttle program “to the
fullest extent possible consistent with a successful development program” in
developing the vehicles now known as Orion, Ares I, and Ares V. It also required
the development of a transition plan for personnel affected by the termination of
the shuttle program.86
•
In the Commerce, Justice, Science, and Related Agencies Appropriations Act,
2008, Congress directed NASA to prepare a strategy, to be updated at least every
six months, for minimizing job losses as a result of the transition from the shuttle
to its successor.87 The strategy report was first issued in March 2008 and was
updated in October 2008 and July 2009.88 As well as strategic information, it
provides annual workforce projections for each NASA center and a summary of
recent relevant actions by NASA and its contractors.
•
In the NASA Authorization Act of 2008, Congress directed NASA to submit a
plan for the disposition of the shuttles and associated hardware and to establish a
Space Shuttle Transition Liaison Office to assist affected communities.89 It
provided for temporary continuation of health benefits for personnel whose jobs
are eliminated as a result of the termination of the program.90 It directed NASA to
analyze the facilities and personnel that will be made available by the termination
of the shuttle program and to report on other current and future federal programs
that could use them.91 The resulting report summarized the “mapping” process
that NASA is using to align the civil servant and contractor shuttle workforce and
the shuttle facilities at each NASA center with the needs of other programs.92
•
In the Commerce, Justice, Science, and Related Agencies Appropriations Act,
2010, and in previous NASA appropriations acts for several years, Congress
prohibited NASA from using appropriated funds to implement reductions in force
(RIFs) or other involuntary separations, except for cause.93

shuttle program were expected to transition to the Constellation program. The new direction for

NASA’s human spaceflight program established by the NASA Authorization Act of 2010
introduces new uncertainty into these plans.
International Space Station
The ISS is composed of crew living space, laboratories, remote manipulator systems, solar arrays
to generate electricity, and other elements. Launched separately, these elements were assembled
in space. Rotating crews have occupied the ISS, each for a period of four to six months, since
November 2000.94
When the space station was first announced, its assembly was to be complete by 1994. In 1998,
when construction actually began, it was expected to be complete by 2002, with operations
through at least 2012. Completion is now scheduled during 2011. In 2003, NASA briefing charts
showed operations possibly continuing through 2022. Under the Vision, announced in 2004, U.S.
utilization was scheduled to end after 2015. The NASA Authorization Act of 2010 extended U.S.
utilization through at least FY2020.95
The framework for international cooperation on the ISS is the Intergovernmental Agreement on
Space Station Cooperation, which was signed in 1998 by representatives of the United States,
Russia, Japan, Canada, Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway,
Spain, Sweden, Switzerland, and the United Kingdom. The intergovernmental agreement has the
status of an executive agreement in the United States, but is considered a treaty in all the other
partner countries. It is implemented through memoranda of understanding between NASA and its
counterpart agencies: the Russian Federal Space Agency (Roskosmos), the Japanese Aerospace
Exploration Agency (JAXA), the Canadian Space Agency (CSA), and the European Space
Agency (ESA).96 The United States also has an ISS participation agreement with Brazil,
independent of the 1998 framework.
Because of cost growth and schedule delays, the scope and capabilities of the ISS have repeatedly
been downsized.97 The original concept was not just a laboratory, but also an observatory; a
transportation node; a facility for servicing, assembly, and manufacturing; and a storage depot
and staging base for other missions.98 By 1989, only the laboratory function remained, and even
that was smaller and less capable than in the original plans. In 1993, Russia joined the space
station partnership, a move that added foreign policy objectives to the program’s goals. By 2001,
following further downsizing, NASA saw three goals for the station: conducting world-class
research, establishing a permanent human presence in space, and “accommodation of all
international partner elements.”99 Following the announcement of the Vision in 2004, learning to

live and work in space became a key justification for the ISS program, and ISS research was to be
focused on the long-term effects of space travel on human biology.
Concerned that the station’s function as a research laboratory was being eroded, Congress took
several legislative actions. The NASA Authorization Act of 2005 required NASA to allocate at
least 15% of the funds budgeted to ISS research to “life and microgravity science research that is
not directly related to supporting the human exploration program.”100 It also required NASA to
submit a research plan for utilization of the ISS.101 Issued in June 2006, the plan described
proposed R&D and utilization activities in each of six disciplinary areas.102 It characterized the
ISS as a long-duration test-bed for future lunar missions; a flight analog for future missions to
Mars; a laboratory for research directly related to human space exploration, such as human health
countermeasures, fire suppression, and life support; and an opportunity to gain experience in
managing international partnerships for long-duration space missions. The plan stated that
research not related to exploration would continue “at a reduced level.” At about the same time,
the National Academies issued a review of NASA’s plans for the ISS.103 This review noted “with
concern” that the objectives of the ISS “no longer include the fundamental biological and
physical research that had been a major focus of ISS planning since its inception.” It concluded
that “once lost, neither the necessary research infrastructure nor the necessary communities of
scientific investigators can survive or be easily replaced.”
ISS National Laboratory
The 2005 authorization act designated the U.S. portion of the ISS as a national laboratory, to be
available for use by other federal agencies and the private sector.104 As required by the act, NASA
submitted a plan for this designation in May 2007.105 It concluded that NASA use of the ISS must
continue to have first priority, that use by non-NASA entities should be funded by those entities,
and that “the availability of cost-effective transportation services will directly affect the ability of
the ISS to operate as a national laboratory in the years to come.” The impact that the national
laboratory designation would have was initially unclear. In the NASA Authorization Act of 2008,
Congress directed NASA to establish an advisory committee on the effective utilization of the ISS
as a national laboratory.106 As of mid-2009, NASA had established agreements for use of the ISS
with at least five other federal agencies, three private firms, and one university, and had identified
“firm interest” in using the ISS for education; human, plant, and animal biotechnologies;

aerospace technologies; and defense sciences research.107 NASA officials believe that about half
of planned U.S. utilization resources on the ISS could be available for non-NASA use.108
The NASA Authorization Act of 2010 directed NASA to contract with a nonprofit organization to
manage the activities of the ISS national laboratory.109 Under this provision, 50% of the U.S.
research capacity allocation on the ISS will be reserved for experiments managed through the
national laboratory process, and NASA utilization in excess of 50% will have to be requested
through a proposal to the managing organization. NASA expects to select the managing
organization no sooner than May 2011.110
ISS Service Life Extension
The U.S. ISS components were designed for a 15-year lifetime from the date of deployment.
They were launched at various times during the assembly process, but the nominal reference
point is considered to be the launch of the U.S. laboratory module Destiny in February 2001.
Despite the 15-year specification, past experience “clearly indicates that systems are capable of
performing safely and effectively for well beyond their original design lifetime” if properly
maintained, refurbished, and validated. The first milestones for a decision on service life
extension past February 2016 will occur in 2014.111
In order to receive a greater return on the cost and effort that have been invested in ISS
construction, the NASA Authorization Act of 2010 extended operation and utilization of the ISS
through at least FY2020. It also directed NASA to carry out a comprehensive review to identify
spare and replacement parts that this extension will necessitate. A report on the review is to be
provided to Congress in January 2011, and the Government Accountability Office is to provide its
assessment of the report within 90 days after that.112
In addition to cost, extending the life of the ISS will require overcoming several technical
challenges. At present, failed parts are returned to Earth in the space shuttle for refurbishment.
After the conclusion of the shuttle program, this repair strategy will likely no longer be possible,
as most of the cargo vehicles being considered for the post-shuttle period are not capable of
returning cargo back to Earth.113 Instead, new parts will need to be manufactured and sent up, but
even this may be impossible in a few cases, as some ISS parts are too large for any of the planned

post-shuttle cargo alternatives. Last but not least, as ISS components reach the end of their 15year design life, they will need to be recertified, which is a potentially complex and costly
process.
Post-Shuttle Access to the ISS
The U.S. space shuttle has been the major vehicle taking crews and cargo to and from the ISS.
Russian Soyuz spacecraft also carry both crews and cargo. Russian Progress spacecraft carry
cargo only, as they are not designed to survive reentry into the Earth’s atmosphere. A Soyuz is
always attached to the station as a “lifeboat” in case of an emergency. The “lifeboat” Soyuz must
be replaced every six months.
Paying Russia for flights on the Soyuz is the only short-term option for U.S. human access to the
ISS after the end of the space shuttle program. In 2009, in order to permit such payments,
Congress extended a waiver of the Iran, North Korea, and Syria Nonproliferation Act (P.L. 106178 as amended) until July 1, 2016.114
One element of NASA’s plans for ensuring cargo access to the ISS during the gap is the
Commercial Orbital Transportation Services (COTS) program to develop commercial capabilities
for cargo spaceflight. Under the COTS program, SpaceX Corporation is developing a vehicle
known as Dragon, and Orbital Sciences Corporation is developing a vehicle known as Cygnus.
Both are cargo-only vehicles (at least in their initial versions) and will have about one-eighth the
capacity of the space shuttle.115 Only Dragon will be capable of returning cargo to Earth as well
as launching it into space. The first test flight of Dragon took place successfully in December
2010. Cygnus has not yet flown into space. In the NASA Authorization Act of 2008, Congress
directed NASA to develop a contingency plan for post-shuttle cargo resupply of the ISS in case
commercial cargo services are unavailable.116 This plan was transmitted to Congress in March
2010.117
Noncommercial alternatives for cargo, in addition to the Russian Progress, include the European
Automated Transfer Vehicle (ATV) and the Japanese H-II Transfer Vehicle (HTV). The first ATV
was launched in March 2008 and carried out docking demonstrations with the ISS the following
month. The first HTV was launched in September 2009 and also docked successfully with the
ISS. Contracting with Russia for use of the Progress would probably require passing an additional
waiver of the Iran, North Korea, and Syria Nonproliferation Act. Like Dragon and Cygnus, the
ATV, HTV, and Progress all have significantly smaller cargo capacity than the space shuttle.118
None of the noncommercial alternatives is capable of returning cargo to Earth.

The Future of NASA: Space Policy Issues Facing Congress
In addition to commercial cargo services, the NASA Authorization Act of 2010 authorized the
establishment and funding of a program to advance the development of commercial services that
could carry crews. Commercial crew transportation services are discussed further in the next
section.
Future Access to Space
Whatever spacecraft are ultimately used for access to the ISS following the end of the space
shuttle program, in the long term new vehicles will be needed to carry humans and cargo into
space, both to low Earth orbit and beyond. Under the Constellation program, these vehicles would
be the crew capsule Orion, the Ares I rocket to launch Orion into low Earth orbit, and the heavylift Ares V rocket to launch cargo. Under the new direction established by the NASA
Authorization Act of 2010, they would be a multipurpose crew vehicle based on Orion; a new,
crew-capable, heavy-lift rocket referred to in the act as the space launch system; and commercial
services to carry astronauts to and from low Earth orbit. (The multipurpose crew vehicle and
space launch system would together provide a backup option in the event that those commercial
services are not available when needed.) A variety of alternatives to these plans have been
proposed, particularly with respect to heavy-lift rockets.
Orion and Ares
Development of Orion and Ares I is well under way by NASA and its contractors. Development
of Ares V has not begun, but Ares I and Ares V would share some components. If the
Constellation program were continued, the first crewed flight of Orion and Ares would be
scheduled for 2015. The Augustine committee concluded that a 2017 date is more realistic and
that a delay until 2019 is possible.
Orion is similar to an enlarged Apollo capsule. It is designed to carry six astronauts and to operate
in space for up to six months. An upgraded version would be required for travel to the Moon or
beyond. The Augustine committee concluded that Orion “will be acceptable for a wide variety of
tasks in the human exploration of space” but expressed concern about its operational cost once
developed. The committee suggested that a smaller, lighter, four-person version could reduce
operations costs for support of the ISS by allowing landing on land rather than in the ocean and
by enabling simplifications in the launch-abort system.119
The Ares I rocket is designed to be a high-reliability launcher that, when combined with Orion,
will yield a crew transport system with an estimated 10-fold improvement in safety relative to the
space shuttle. The development of Ares I has encountered some technical difficulties, but the
Augustine committee characterized these as “not remarkable” and “resolvable.”120
Ares V is designed to be capable of launching 160 metric tons of cargo into low Earth orbit.121 By
comparison, the space shuttle has a cargo capacity for ISS resupply missions of about 16 metric

tons, and the ISS, which was launched in pieces over a decade, weighs a total of 350 metric
tons.122 For human missions beyond low Earth orbit, Ares V would launch equipment into orbit
for rendezvous with an Orion launched by an Ares I. At present, Ares V is only a conceptual
design. The Augustine committee described it as “an extremely capable rocket” but estimated that
it was unlikely to be available until the late 2020s.
Multipurpose Crew Vehicle and Space Launch System
For human space flight beyond low Earth orbit, the NASA Authorization Act of 2010 directed
NASA to develop a multipurpose crew vehicle, based on Orion, and a new crew-capable, heavylift rocket known as the space launch system.
The multipurpose crew vehicle would “continue to advance the development” of the features,
designs, and systems of Orion. Its capabilities would include serving as the primary crew vehicle
for missions beyond low Earth orbit; conducting in-space operations, such as rendezvous,
docking, and extra-vehicular activities; and delivering crews and cargo to the ISS, if commercial
and other alternative services are unavailable. The act established December 31, 2016, as the
target date for achieving full operational capability.123
The capabilities of the space launch system would include lifting the multipurpose crew vehicle;
initially, without an upper stage, lifting payloads weighing between 70 and 100 metric tons into
low Earth orbit; with an integrated upper stage, lifting payloads weighing at least 130 metric tons;
and delivering crews and cargo to the ISS, if commercial and other alternative services are
unavailable. December 31, 2016, is the target date for achieving full operational capability of the
initial version, without an upper stage.
In January 2011, NASA submitted a preliminary report to Congress on its plan for implementing
the authorization act’s requirements for the multipurpose crew vehicle human and space launch
systems.124 The report stated that NASA has not yet been able to identify spacecraft designs that
meet the act’s capability and schedule requirements within the authorized funding levels.
Heavy-Lift Alternatives
The Augustine committee identified three categories of heavy-lift launchers that could be
alternatives to Ares V: a scaled-down version of Ares V called Ares V Lite; a rocket derived from
the design of the space shuttle; and a rocket derived from the Evolved Expendable Launch
Vehicle. Unlike Ares V, each of these could be rated to carry humans (in an Orion capsule) as well
as cargo.125

The Future of NASA: Space Policy Issues Facing Congress
The Ares V Lite would be a slightly lower-performance version of the Ares V, capable of
launching about 140 metric tons rather than 160. For human missions beyond Earth orbit, two
launches of Ares V Lite, rather than one of Ares I and one of Ares V, would considerably increase
the payload that could be carried to the destination. Some human missions beyond Earth orbit
could be accomplished with a single Ares V Lite launch.126
Shuttle-derived vehicles would use the same main engines, solid rocket boosters, and external
tanks as the space shuttle. They could be either in-line or side-mount. In other words, the payload
could be mounted either on top or on the side. One example of the in-line option is the Jupiter
design advocated by DIRECT, a group ostensibly led by NASA engineers working anonymously
on their own time.127 The Augustine committee did not compare the in-line and side-mount
variants in detail, but it considered the side-mount option to be inherently less safe when carrying
a crew. A shuttle-derived launcher would likely be able to lift 90 to 110 metric tons into orbit.
The Evolved Expendable Launch Vehicle program was a U.S. Air Force program that resulted in
the development of the Delta IV and Atlas V rockets. Current EELV systems are not rated to carry
humans. In testimony to the Augustine committee, the Aerospace Corporation stated that a
human-rated variant of the Delta IV Heavy would be capable of carrying Orion to the ISS.128 A
super-heavy EELV variant could carry a cargo payload of about 75 metric tons. The Augustine
committee concluded that using an EELV variant to launch Orion would only make sense if a
super-heavy EELV variant were to be selected for heavy-lift cargo launch.
In addition to differences in capability, the Augustine committee found that these alternatives
differ in their life-cycle costs, operational complexity, and “way of doing business.” The
committee concluded that Ares V Lite would be the most capable; that a shuttle derivative would
take maximum advantage of existing infrastructure, facilities, and production capabilities; and
that an EELV derivative could potentially have the lowest operating costs, but would require a
significant restructuring of NASA. The committee noted that each alternative has strong
advocates and that “the claimed cost, schedule, and performance parameters include varying
degrees of aggressiveness.”129 It did not explicitly recommend any of the alternatives over the
others.
The NASA Authorization Act of 2010 directed NASA to “extend or modify existing ... contracts”
when developing the new space launch system. Moreover, Senate report language anticipated that
in order to meet the specified vehicle capabilities and requirements, the most cost-effective
and “evolvable” design concept is likely to follow what is known as an “in-line” vehicle
design, with a large center tank structure with attached multiple liquid propulsion engines

and, at a minimum, two solid rocket motors composed of at least four segments being
attached to the tank structure to form the core, initial stage of the propulsion vehicle.130
This language is seen by most analysts as calling for a design similar to the Augustine
committee’s Ares V Lite option, or possibly another in-line shuttle-derived design. Some
observers have questioned whether it is appropriate for Congress to give such specific guidance
about engineering design choices.131 NASA officials have indicated their intent to “work with
stakeholders in Congress to determine an appropriate transportation architecture”132 and have
stated that “we have done some very objective heavy-lift studies [and] will try to influence the
conversation to make sure we don’t preclude possible answers that might be the optimum
overall.”133
Commercial Crew Transportation Services
The NASA Authorization Act of 2010 authorized the establishment and funding of a program to
advance the development of commercial services that can carry astronauts. The Commercial
Crew Development (CCDev) program extends and authorizes an initiative begun with funds from
the American Recovery and Reinvestment Act of 2009 (ARRA, P.L. 111-5). A number of
companies, including SpaceX, Orbital, Boeing, Virgin Galactic, and the Sierra Nevada
Corporation, have expressed interest in providing commercial crew launch services.134 Before
CCDev, the COTS program considered the use of commercial services for ISS crew transfer and
crew rescue (a capability known as COTS D).
Regarding the option of relying on commercial services in lieu of Ares I for all crew access to low
Earth orbit, the Augustine committee concluded the following:135
•
Considering that all U.S. crew launch systems to date have been built by industry,
“there is little doubt” that the U.S. aerospace industry is capable of building and
operating a four-passenger “crew taxi” to low Earth orbit.
•
Because of the importance of crew safety, commercial crew transport services
would need to include “a strong, independent mission assurance role for NASA.”
•
If the service were developed so as to meet commercial needs as well as NASA’s,
there would be private-sector customers to share operating costs with NASA. In

that case, the cost of the program to NASA would be about $5 billion, and a
service could be in place by 2016.
•
If the private sector effort were to fail in mid-program, the task of crew transport
would revert to NASA. NASA should continue development of Orion and move
quickly toward the development of a human-ratable heavy-lift rocket as a
fallback option to mitigate this risk.
The Augustine committee found that the commercial space industry is “burgeoning,” and
concluded that creating an assured initial market would eventually have the potential—“not
without risk”—to significantly reduce costs to the government.
Issue for Congress: Safety
Space travel is inherently dangerous. Nevertheless, NASA’s policy is that “safety is and will
always be our number one priority in everything we do.”136 The Augustine committee described
safety as a sine qua non.137 Analysts and policy makers generally agree with this emphasis, but
some have concerns about whether it is matched by NASA’s implementation of its safety policies
and procedures.
The Columbia Accident Investigation Board found in 2003 that “throughout its history, NASA
has consistently struggled to achieve viable safety programs and adjust them to the constraints
and vagaries of changing budgets.... NASA’s safety system has fallen short of the mark.”138 It
concluded that “a broken safety culture,” including a “reliance on past success as a substitute for
sound engineering practices,” was an organizational cause of the Columbia disaster.139 It found
that one contributing factor was “intense schedule pressure,” which had also been identified as an
organizational cause of the space shuttle Challenger disaster in 1986.140 It recommended that
NASA establish a technical engineering authority, reporting directly to the NASA Administrator
rather than to the space shuttle program, that independently verifies launch readiness and has sole
authority to grant waivers for technical standards.141 In response to these findings, NASA has
made many changes, including the establishment of an independent NASA Engineering and
Safety Center under the auspices of the headquarters Office of Safety and Mission Assurance.
Nevertheless, some analysts see signs that potential problems remain. The deadline of 2010 to
complete construction of the space station and stop flying the space shuttle created schedule
pressure for both programs until NASA converted it from a hard deadline to a flexible goal (now
extended to early 2011). In 2006, NASA decided to a proceed with a shuttle mission, even though
the Chief Engineer and the head of the Office of Safety and Mission Assurance recommended
against the launch because of an issue with the shuttle ice-frost ramps that they characterized as

“probable/catastrophic.”142 Some observers saw signs of “reliance on past success” in NASA’s
justification for this decision: the NASA Administrator disagreed with the “probable”
characterization because “we have 113 flights with this vehicle ... and while we’ve had two loss
of vehicle incidents, they’ve not been due to ice-frost ramps.”143 (The two officials who
recommended against launch stated that they were comfortable with the decision to overrule them
because “the risk was to the vehicle and not the crew.”)144 A member of NASA’s Aerospace
Safety Advisory Panel testified in late 2009 that describing safety as a sine qua non
“oversimplifies a complex and challenging problem” and that NASA “has given serious
consideration only recently” to the establishment of safety requirements for commercial crew
transport services.145
NASA argues that it continues to implement initiatives to improve safety. These include greater
emphasis on training and qualification of safety professionals; an emphasis on “safety culture,”
including more open communication and clear appeal paths to the Administrator for safety-related
dissenting opinions; more modeling and validation of software requirements; and improved tools
for knowledge and requirements management.146
The advent of commercial spacecraft that carry crews into space will require new processes for
ensuring crew safety. The NASA Authorization Act of 2010 directed NASA to develop and make
public “detailed human rating processes and requirements” for crewed commercial spacecraft that
are “at least equivalent to” the existing requirements for human rating of NASA spacecraft.147
NASA issued this document in December 2010.148 It asserts that “a crew transport capability that
meets the safety requirements in this document will be approximately an order of magnitude safer
than the space shuttle.”149
Destinations for Human Exploration
Until 2010, the Vision for Space Exploration established the Moon as NASA’s next goal for
human exploration beyond low Earth orbit, followed eventually by Mars. In considering possible
modifications to the Vision, space policy experts and other interested observers suggested various
alternative goals. For example, some proposed that Mars should be the immediate objective,

rather than returning to the Moon first.150 Others suggested human missions to asteroids or other
solar system destinations.
The Augustine committee concluded that current technology is insufficiently developed to make a
Mars mission safe. It found that Mars is “unquestionably the most interesting destination in the
inner solar system” and the “ultimate destination for human exploration” but “not the best first
destination.”151 A spacecraft that lands on either the Moon or Mars must overcome the lunar or
Martian “gravity well” before returning to Earth.152 The fuel required to accomplish this makes
either destination challenging. As potential alternatives, the Augustine committee considered flyby missions to either the Moon or Mars, missions that would orbit either the Moon or Mars,
missions that would land on the moons of Mars, and missions to near-Earth objects such as
asteroids or comets. They also considered missions to various Lagrange points. Lagrange points
are special locations in space, defined relative to the orbit of the Moon around the Earth or the
Earth around the Sun. They are planned locations for future unmanned science spacecraft, and
some scientists believe they will be important in determining routes for future interplanetary
travel. Possible activities at each of these destinations are shown in Figure 1.
The Administration’s plan, first articulated in the President’s speech in April 2010,153 is for
NASA’s first destination beyond low Earth orbit to be an asteroid, followed by an orbit of Mars
and subsequently a Mars landing. This plan appears to be consistent with the NASA
Authorization Act of 2010, which states that “a long-term objective for human exploration of
space should be the eventual international exploration of Mars.”154 The act also, however,
mandates a review by National Academies of the goals, capabilities, and direction of human space
flight.155
Alternatives to Human Exploration
Given the costs and risks of human space exploration, Congress could decide to curtail or
postpone future human exploration missions and shift the emphasis of the nation’s space program
to other endeavors. The cost of human exploration is substantial, and according to the Augustine
committee, it is not a continuum: there is an “entry cost” below which a successful program
cannot be conducted at all.156 Congress could decide that this minimum cost is not affordable.
Similarly, no matter how energetically NASA addresses safety concerns, human spaceflight is an
inherently risky endeavor. Congress could decide that the potential benefits are insufficient to
justify the safety risks.

At least one observer has suggested the launching humans to Mars without plans to return them to Earth. See

option would be politically viable.

Notes: L1 and L2 refer to particular Lagrange points (see text). A NEO is a near-Earth object such as an
asteroid or a comet.
Several options are available as alternatives to human space exploration. Congress could seek to
accomplish some of the same goals through other means, such as through robotic exploration. It
could focus on technology development, in the hope of developing new technology that makes
human spaceflight safer and more affordable in the future. It could focus on NASA’s other
activities, such as Earth science and aeronautics. Given sufficient funding, of course, all these
options are also available in conjunction with human exploration rather than as alternatives to it.
For example, the Augustine committee acknowledged that robotic exploration is important as a
precursor to human exploration.
Robotic Exploration
Advocates of robotic missions assert that robotic exploration can accomplish outstanding science
and inspire the public just as effectively as human exploration. The Mars rovers are a familiar
example of a successful robotic science mission that has captured considerable public attention.
Advocates also claim that robotic missions can accomplish their goals at less cost and with
greater safety than human missions. They do not need to incorporate systems for human life
support or human radiation protection, they do not usually need to return to Earth, and they pose
no risk of death or injury to astronauts. Some analysts assert further that exploring with humans
Congressional Research Service
33
The Future of NASA: Space Policy Issues Facing Congress
“rules out destinations beyond Mars.”157 Given that current plans include no destinations beyond
Mars and treat Mars itself only as a long-term goal, this last limitation may not be important in
the near term, even if it is correct.
Advocates of human missions note that science is not NASA’s only purpose and claim that human
exploration is more effective than robotic exploration at such intangible goals as inspiring the
public, enhancing national prestige, and satisfying the human urge to explore and discover. They
assert that even considering science alone, human missions can be more flexible in the event of
an unforeseen scientific opportunity or an unexpected change in plans. As support for this
assertion, they often cite the human missions to repair and upgrade the Hubble telescope. On the
other hand, the Hubble repairs and upgrades required extensive planning and the development of
new equipment. They were not a real-time response to an unexpected event. Moreover, robotic
missions can also sometimes be modified to respond to opportunities and mishaps, through
software updates and other changes worked out by scientists and engineers back on Earth.
A few analysts portray robotic exploration as an alternative to human exploration. For the most
part, however, the two alternatives are considered complementary, rather than exclusive. The
Augustine committee, for example, found that without both human and robotic missions, “any
space program would be hollow.”158 In addition, many analysts consider that in the absence of
human missions, support for NASA as a whole would dwindle, and fewer resources would be
available for robotic missions as well.
Emphasize Technology Development
If congressional policy makers were to conclude that cost and safety concerns make a human
exploration program unaffordable or undesirable in the near term, they might seek to scale back
NASA’s human spaceflight program and focus on technology development, in the hope that
improved technology will make the costs and risks of space travel more attractive in the future.
The strategy of developing improved technology and acquiring greater expertise could take many
forms. It could complement a continuing, aggressive program of human exploration. For
example, it is similar, in some ways, to the Augustine committee’s suggestion (in its “flexible
path” option) of visiting a series of less challenging destinations before attempting a Moon
landing. It could also accompany a program of human missions in low Earth orbit without
immediate plans for more distant destinations. It could even be part of a program that abandoned
human spaceflight in the near term. Developing new technology effectively would likely be
difficult, however, without a means of testing it in realistic missions. A program without any
human spaceflight at all would risk losing existing expertise through inactivity.
The Augustine committee, the National Academies, and the Administration’s FY2011 budget
proposals all recommended a greater emphasis on technology development as a complement to an
ongoing program of human spaceflight. The Augustine committee described NASA’s space
technology program as “an important effort that has significantly atrophied over the years.”159 It

recommended that technology development be closely coordinated with ongoing programs, but
conducted independently of them. The National Academies also recommended that NASA
revitalize its technology development program. Like the Augustine committee, the Academies
concluded that this program should be conducted independently. They recommended that NASA
establish a DARPA-like technology development organization that reports directly to the
Administrator.160
The NASA Authorization Act of 2010 accepted the Administration’s request to establish a new
space technology program, although the funding it authorized for this effort was less than the
Administration had proposed. It directed NASA to provide an implementation plan for the
program by February 2011, and it directed the Administration to develop a national policy to
guide space technology development programs across the federal government through 2020.161
Other Space Policy Issues
In addition to the programmatic and prioritization issues that are the main focus of this report,
NASA faces some cross-cutting challenges, such as acquisition and financial management, and
issues involving its relationships with other agencies and the commercial space launch industry.
NASA Acquisition and Financial Management
Since 1990, the GAO has identified acquisition management at NASA as a high-risk area for the
federal government.162 Although a 2009 update noted that “NASA has made a concerted effort to
improve its acquisition management,” it also stated that “since fiscal year 2006, 10 out of 12 ...
major development projects in implementation exceeded their baseline thresholds.”163 NASA
issued an improvement plan in response to GAO’s finding.164 The NASA Authorization Act of
2010 directed NASA to submit annual reports on its implementation of the improvement plan.165
In the NASA Authorization Act of 2005, Congress established requirements for baselines and cost
controls.166 The requirements include additional reviews of any program that appears likely to
exceed its baseline cost estimate by 15% or its baseline schedule by six months and a prohibition
on continuing any program that exceeds its cost baseline by 30% unless Congress specifically

authorizes the program to continue. These requirements are similar to the Nunn-McCurdy costcontainment requirements for the Department of Defense.
In November 2008, the NASA Inspector General identified financial management as one of
NASA’s most serious challenges.167 The Inspector General’s report found continuing weaknesses
in NASA’s financial management processes and systems, including its internal controls over
property accounting. It noted that these deficiencies had resulted in disclaimed audits of NASA’s
financial statements since FY2003, largely because of data integrity issues and a lack of effective
internal control procedures. According to the report, NASA had made progress in addressing
these deficiencies, but the FY2009 audit was again disclaimed.168 The FY2010 audit, however,
was qualified, rather than disclaimed; the NASA inspector general called this “a notable
improvement.”169
U.S. Space Policy Governance
A variety of governmental and nongovernmental organizations help to coordinate and guide U.S.
space policy. These include the Office of Science and Technology Policy (OSTP) and the
National Science and Technology Council (NSTC), both in the Executive Office of the President,
as well as outside advisory groups, such as the NASA Advisory Council,170 committees of the
National Academies,171 and independent committees such as the Augustine committee.
The National Academies have recommended that the President
task senior executive-branch officials to align agency and department strategies; identify
gaps or shortfalls in policy coverage, policy implementation, and resource allocation; and
identify new opportunities for space-based endeavors that will help to address the goals of
both the U.S. civil and national security space programs.172
The Obama Administration has stated that it intends to reestablish the National Aeronautics and
Space Council (NASC), “which will report to the President and oversee and coordinate civilian,
military, commercial and national security space activities.”173 The NASC was established along
with NASA itself by the National Aeronautics and Space Act of 1958 (P.L. 85-568). It was most
active during the Kennedy Administration, when it recommended, among other policies, the
Apollo program to send humans to the Moon. Some analysts attribute its influence during this

period to the fact that it was chaired by Vice President Johnson. The NASC was abolished in
1973, reestablished in 1989 as the National Space Council, then abolished again in 1993, with its
functions absorbed into the NSTC.
Some aspects of space policy are documented in a formal presidential statement of national space
policy. In 2006, the Bush Administration issued such a statement,174 replacing a previous one that
had been in place for 10 years.175 The 2006 policy established principles and goals for U.S.
civilian and national security space programs and set guidelines for a few specific issues such as
the use of nuclear power in space and the hazard of debris in orbit. It defined the space-related
roles, responsibilities, and relationships of NASA and other federal agencies, such as the
Department of Defense and the Department of Commerce. The Obama Administration issued an
updated national space policy in June 2010.176 The new policy reiterated the policy changes
proposed in the Administration’s FY2011 budget and placed new emphasis on international
cooperation and development of the commercial space industry.
U.S. National Security Space Programs
National security space programs, conducted by the Department of Defense (DOD) and the
intelligence community, are less visible than NASA, but their budgets are comparable to NASA’s.
A key issue for them is how to avoid the cost growth and schedule delays that have characterized
several recent projects. A shared industrial base and other areas of common concern sometimes
result in NASA issues affecting national security programs and vice versa. For example, some
policy makers expressed concern about the impact of cancelling of Ares I on the industrial base
for solid rocket motors used by DOD.177 The NASA Authorization Act of 2010 directed NASA to
assess, in consultation with DOD and the Department of Commerce, the effects of the end of the
space shuttle program, and the transition to the space launch system authorized by the act, on the
U.S. industrial base for solid and liquid rocket motors.178 Further discussion of national security
space programs is beyond the scope of this report.
NASA’s Relationship with NOAA
Congressional policy makers have taken a long-standing interest in NASA’s relationship with the
National Oceanic and Atmospheric Administration (NOAA), which operates Earth observing
satellites for weather forecasting and other purposes. The NASA Authorization Act of 2005
mandated the establishment of a joint NASA-NOAA working group; required NASA and NOAA
to submit a joint annual report on coordination each February; directed NASA and NOAA to
evaluate NASA science missions for their operational capabilities and prepare transition plans for
those with operational potential; and directed NASA not to transfer any Earth science mission or

Earth observing system to NOAA until a transition plan has been approved and funds have been
included in the NOAA budget request.179 In the NASA Authorization Act of 2008, Congress
directed OSTP to develop a process for transitions of experimental Earth science and space
weather NASA missions to operational status under NOAA, including the coordination of agency
budget requests;180 mandated a National Academies study of the governance structure for U.S.
Earth observation programs at NASA, NOAA, and other agencies, to be transmitted to Congress
by April 2010;181 and mandated a National Academies assessment of impediments to interagency
cooperation on space and Earth science missions.182 The report was on impediments to
cooperation was issued in November 2010.183 The NASA Authorization Act of 2010 directed
OSTP to develop a strategic plan, updated at least every three years, to ensure greater cooperation
among U.S. civilian Earth observation programs; and directed NASA to coordinate with NOAA
and the U.S. Geological Survey (USGS) to establish a formal mechanism to transition NASA
research and assets to NOAA and USGS operations.184 The extent to which the provisions in the
2005, 2008, and 2010 acts overlap suggests that the requirements of the earlier acts have not yet
been successful in achieving Congress’s goals for the NASA-NOAA relationship.
The U.S. Commercial Space Industry
Industry has long had an important role in both space launch and the development and operation
of commercial satellites. Although the commercial satellite launch business has dropped off in
recent years, many analysts expect the industry to expand as space tourism develops and NASA
begins to rely more on the commercial sector for space transportation.
The prospect of space tourism on commercial vehicles is becoming increasingly likely. With the
exception of five suborbital demonstration flights in 2004, private space travel has until now been
limited to the purchase of trips to the International Space Station on Russian Soyuz spacecraft. A
number of commercial companies are now developing reusable spacecraft to carry private
individuals on short-duration flights into the lower reaches of space. Concurrently, several
companies and states are developing spaceports to accommodate anticipated increases in
commercial space launches. The safety of commercial space launches, spaceports, and space
tourism are regulated by the Federal Aviation Administration (FAA). According to the GAO, the
FAA faces a number of challenges in commercial space regulation, including maintaining
sufficient space expertise to conduct proper oversight, avoiding conflicts between its regulatory
and promotional roles, and integrating spacecraft into the air traffic control system.185
Export control regulations administered by the Department of State under the International Traffic
in Arms Regulations (ITAR) have often been a concern for this industry. The regulations limit the

export of satellites and related components because of the potential for their use in military
systems. In order to expand opportunities for U.S. industry, some analysts and policy makers have
advocated transferring the regulation of these technologies from ITAR to the Export
Administration Regulations administered by the Department of Commerce.186 In April 2010,
following an interagency review, the Administration proposed a number of changes in the U.S.
export control system, including the establishment of a single licensing agency.187
The development of commercial vehicles for cargo flights to the space station, and possibly to

Legislation in the 111th Congress
The NASA Authorization Act of 2010 (P.L. 111-267) is discussed above in the section “Human
Spaceflight: The 2010 Authorization Act” and elsewhere throughout this report.
Appropriations for NASA are provided in the Commerce, Justice, Science (CJS) appropriations
bill. For more information on FY2011 appropriations legislation, see CRS Report R41161,
Commerce, Justice, Science, and Related Agencies: FY2011 Appropriations. Like other agencies,
NASA is currently operating at FY2010 funding levels under a continuing resolution, the
Continuing Appropriations Act, 2010 (P.L. 111-242 as amended by P.L. 111-322).
For FY2010, the CJS bill was passed by the House and Senate as H.R. 2847. For final passage, it
was included in the Consolidated Appropriations Act, 2010 (P.L. 111-117). For more information
about FY2010 NASA appropriations, see CRS Report R40644, Commerce, Justice, Science, and
Related Agencies: FY2010 Appropriations.
For FY2009 NASA appropriations legislation during the 111th Congress, including passage of the
American Recovery and Reinvestment Act of 2009 (P.L. 111-5) and the Omnibus Appropriations
Act, 2009 (P.L. 111-8), see CRS Report RL34540, Commerce, Justice, Science and Related
Agencies: FY2009 Appropriations.
A number of other bills addressing specific topics related to NASA were introduced during the
111th Congress. Among these, P.L. 111-125 extended the current third-party liability
indemnification for commercial launch services companies through 2012. P.L. 111-314 restated
existing law relating to NASA and other space topics as a new, separate title of the U.S. Code.188
Bills that did not become law included the following: H.R. 4804 and S. 3068, which would have
extended the space shuttle and ISS programs, provided for the development of a National Space

Transportation system, and authorized appropriations for certain NASA programs; H.R. 1962,
which would have extended the space shuttle program to 2015; H.R. 3853, which would have
authorized grants to university consortia to establish centers in conjunction with NASA and
industry; H.R. 5614, which would have required expenditure of appropriated FY2010
Constellation funds on the Constellation program, without terminating or descoping contracts;
and S. 3180, which would have prohibited the use of the Anti-Deficiency Act (31 U.S.C. 1341) as
the basis for terminating or eliminating a Constellation contract, program, project, or activity.
Summary of Major Issues for Congress
In conclusion, major space policy issues facing Congress include the following:
•
Is there a national consensus for human exploration beyond Earth orbit, despite
the inherent risks and the substantial cost?
•
If so, what destination or destinations should NASA’s human exploration
program explore?
•
If human exploration beyond Earth orbit is too costly or too dangerous, should
NASA focus its efforts on human missions in Earth orbit, robotic exploration,
technology development, other activities such as science and aeronautics, or
some combination of these?
•
When the space shuttle program ends during 2011, how should the transition of
shuttle workforce and facilities be managed?
•
Now that U.S. use of the International Space Station has been extended to at least
2020, how can the ISS be managed and utilized most effectively?
•
What can be done to ensure that new spacecraft for human exploration, both
government-owned and commercial, are developed effectively, despite budget
constraints?
•
How should NASA’s multiple objectives be prioritized? What is the proper
balance between human spaceflight, science, aeronautics, and education
programs, and how can the balance be maintained if the cost of the larger, more
prominent programs grows?
