[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]


    Chairman Babin. Good morning. The Subcommittee on Space and 
Aeronautics will now come to order. Without objection, the 
Chair is authorized to declare recesses of the Subcommittee at 
any time.
    And welcome to today's hearing titled ``Advancing 
Scientific Discovery: Assessing the Status of NASA's Science 
Mission Directorate.'' I'd like to recognize myself for 5 
minutes for an opening statement.
    Today's Subcommittee hearing will review the activities of 
NASA's (National Aeronautics and Space Administration's) 
Science Mission Directorate, or SMD, and discuss the challenges 
and opportunities for ensuring success in these activities. 
Scientific research has been a core function of NASA since the 
agency's creation. NASA's science missions have helped us to 
learn more about our planet, discover secrets of the Sun, 
explore our solar system, and better understand our place in 
the universe.
    SMD has had many recent successes. The Perseverance and 
Curiosity rovers are adding to our understanding of Mars and 
enabling us to someday send humans to the Martian surface. The 
Parker Solar Probe continues to deliver unprecedented 
observations of the Sun. Just 6 months ago, OSIRIS-REx 
(Origins, Spectral Interpretation, Resource Identification, 
Security--Regolith Explorer) returned asteroid samples to Earth 
to be studied at the Johnson Space Center. SMD also carries out 
some of NASA's most important work by cataloguing and defending 
our planet from Near-Earth Objects (NEOs).
    However, we cannot celebrate these successes without 
acknowledging the challenges that NASA has faced on missions of 
all sizes. Just 3 weeks ago, NASA's Office of Inspector General 
(OIG) released an audit of the Mars Sample Return mission, 
commonly known as MSR, that NASA hopes to launch in partnership 
with the European Space Agency before the end of this decade. 
Anyone who has read prior reports on NASA's science missions 
from the Inspector General, GAO (Government Accountability 
Office), or other independent review bodies will see familiar 
themes in this audit. Project management challenges, including 
overoptimism on technology development, evolving architectural 
requirements, and underestimating costs are just a few of the 
challenges identified by the Inspector General.
    This Committee recognizes the immense value of the MSR 
mission. We continue to hope that these issues will be resolved 
and that the MSR mission will be successful. However, we cannot 
ignore this now-familiar pattern of schedule and cost overrun 
for many NASA programs. When missions are delayed, costs 
increase as a result. Ripple effects are felt throughout NASA 
as timelines shift and unrelated programs are delayed or 
canceled to accommodate the troubled project.
    Members of this Committee undoubtedly recall the years of 
delays and billions of dollars in cost overruns before the 
James Webb Space Telescope (JWST) was launched. Another 
mission, the Psyche mission, spacecraft, finally launched in 
2023 after more than a year delay, which incurred significant 
costs, impacted other missions such as the VERITAS (Venus 
Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) 
mission, and we want NASA to engage in bold, daring missions.
    But Congress must direct NASA to take on these missions 
with a clear understanding of the associated costs and risks. 
Consistent cost overruns and delays can result in other worthy 
missions being postponed or canceled and can create a 
reluctance for Congress to provide additional funding or even 
approve such missions in the future.
    Congress has a responsibility to weigh the cost of a 
mission with its scientific value and cannot simply rationalize 
cost overruns and schedule delays by stating the end result of 
these missions will be worthwhile. That is unacceptable to our 
constituents and should be unacceptable to us all. This 
Committee has long supported a balanced approach to NASA's 
scientific missions across discipline and mission type. I 
expect that that will continue in the future.
    At Congress' direction, NASA relies on the decadal process 
carried out by the National Academy of Science to prioritize 
its scientific activities. This process seeks a broad range of 
community input to reach a consensus position on priority 
missions for the following decade. Recent decadal surveys 
across disciplines have recommended ambitious missions and 
optimistic budgets. This Committee recognizes the importance of 
the decadal process, but must also recognize the current fiscal 
environment and plan accordingly.
    The focus of today's hearing is not to chide NASA, folks, 
but rather to understand the challenges that NASA faces when 
fulfilling decadal priorities. We also want to be sure that 
both Congress and NASA are applying lessons learned from 
previous missions to facilitate future mission successes.
    I thank our distinguished panel of guests this morning and 
witnesses for joining with us today, and I look forward to a 
productive discussion.

    I thank our distinguished panel of witnesses for joining us

    Chairman Babin. And I would like to now recognize the 
Ranking Member for his statement for 5 minutes.
    Mr. Sorensen. Thank you, Chairman. And I join the Chairman 
in welcoming everyone to today's hearing. We also thank our 
exceptional panel today of witnesses for being here to share 
your expertise.
    Thanks to the Science Mission Directorate, NASA is 
conducting reconnaissance of every planet in our solar system, 
studying the Sun and near-Earth environment, better 
understanding Earth systems, and probing the evolution of 
stars, galaxies, and the early universe. As a scientist myself, 
the only meteorologist in Congress, I'm eager to highlight the 
importance of NASA's work to our Nation and to my constituents 
back home in western and northwestern Illinois.
    Take, for example, the study of Earth science, a field 
which NASA's first-of-its-kind Earth observation investigations 
are helping improve something near and dear to my heart, our 
Nation's operational weather services. These services inform 
the study of trends of severe weather and tornadoes, flooding, 
droughts, which lead to how we use our land. This data can then 
be used by farmers across the Midwest and around the country, 
as an example, NASA's heliophysics programs to study the Sun, 
which help us predict solar storms that can disrupt vital 
satellite communications and GPS (Global Positioning System) 
signals.
    Speaking of NASA's scientific study of the Sun, communities 
around the country will soon have an opportunity to learn 
firsthand about our closest star. On April 8, a total solar 
eclipse where the Moon passes between the Sun and the Earth, 
turning day into night for a few short minutes, will be visible 
in several States, including the southern portion of Illinois. 
Most of the country, including communities in central and 
northwestern Illinois, will witness a partial eclipse. And so I 
would remind everyone, the scientists in Congress, that we 
advocate you only use one of these when you're taking part in 
the solar eclipse.
    But also, I'd be remiss to say it was one of the greatest 
parts of my life driving from Illinois to Wyoming to see the 
last eclipse and the profound impact that it had on me 
personally.
    The opportunities for pursuing important science are vast. 
However, our fiscal resources are not. The Science Mission 
Directorate has many projects ongoing, but we do not have 
unlimited funds. That poses a problem because we need the 
balance between and among the projects under the Science 
Mission Directorate to maintain a healthy distribution of funds 
to small, medium, and large missions. Large high-priority 
missions with significant resource demands have the potential 
to upset the balance within and across NASA's science programs.
    Today's hearing provides an important opportunity to 
examine the nature of this balance and how we can pursue 
ambitious and large missions while maintaining the overall 
health of the Science Mission Directorate portfolio. I'm eager 
to find solutions because leaving high-priority science on the 
chopping block is not the future that I want to see for the 
next generation and for our country.
    I'm proud and excited about what the future holds for 
NASA's science programs. Answers to so many important 
challenging and inspiring questions await us. I look forward to 
working with the Chairman, NASA, and the Administration, as 
well as stakeholders to ensure a bright and bold future for the 
space and Earth science programs undertaken by NASA.
    And I yield back, Mr. Chairman.
    [The prepared statement of Mr. Sorensen follows:]

    Good morning.
    I join the Chairman in welcoming everyone to today's 
hearing, ``Advancing Scientific Discovery: Assessing the Status 
of NASAs Science Mission Directorate.'' We also thank our 
exceptional panel of witnesses for being here today to share

    Thanks to the Science Mission Directorate, NASA is

stars, galaxies, and the early Universe.
    As a scientist and the only meteorologist in Congress, I'm 
eager to highlight the importance of NASA's work to our nation 
and to my constituents in Illinois' 17th District.
    Take, for example, the study of Earth science, a field in 
which NASA's first-of-its-kind Earth observation investigations 
are helping improve something near and dear to my heart--our 
nation's operational weather services. These services inform 
the study of trends in flooding, droughts, and land use. This 
data can then be used by farmers in Central and Northwestern 
Illinois and around the country.
    Speaking of NASA's scientific study of the Sun, communities 
around the country will soon have an opportunity to learn 
first-hand about our closest star. On April 8th, a total solar 
eclipse- where the Moon passes between the Sun and the Earth, 
turning day into night for a few short minutes-will be visible 
in several states, including the southern portion of Illinois, 
while most of the rest of the country, including communities in 
central and western Illinois will witness a partial eclipse.
    I urge everyone to take advantage of this exciting 
educational moment and find a community or State event across 
the U.S. to join and experience a total solar eclipse.
    The opportunities for pursuing important science, are vast. 
However, our fiscal resources are not. The Science Mission 
Directorate has many projects ongoing but does not have

challenging, and inspiring questions await us
    I look forward to working with the Chairman, NASA, and--the 
Administration, as well as stakeholders, to ensure a bright and 
bold future for the space and earth science programs undertaken 
by NASA.
    Thank you, and I yield back.

    Chairman Babin. Thank you, Mr. Sorensen. I really 
appreciate it.
    [The prepared statement of Ms. Lofgren follows:]

    Good morning, and thank you, Chairman Babin and Ranking 
Member Sorensen, for holding today's hearing. I also want to 
welcome our witnesses. We have an incredibly distinguished 
panel who are very familiar to this Committee and have been the 
source of much excellent advice in the past, and I am sure 
today will be no different.
    While NASA's science portfolio and budget have enjoyed 
increases in the recent past, NASA's science programs are 
facing a perfect storm. The recently enacted appropriations cut 
NASA's budget, and NASA's science portfolio took an outsized 
share of the decrease. The guidelines set under the debt 
ceiling agreement limit further funding growth. Cost and 
schedule growth on existing projects exacerbate the 
constraints. The building pressures on the portfolio leave less 
and less flexibility to accommodate the unexpected and no room 
for new decadal survey science to get underway. NASA has 
already had to take the difficult step to delay important 
missions under development, even ones that are performing well. 
The FY2025 budget request that Congress just received proposes 
more delays, descopes, and cancellations, and not just to new 
missions under development, but to active missions, including 
to a high-performing Great Observatory.
    These decisions are hard, and they have real consequences. 
NASA's science missions and programs also support an entire 
ecosystem of scientists, engineers, technicians, professors, 
students, science communicators, and more. Skilled talent, once 
lost, may not be easily regained. We must consider the value of 
ensuring continuity of critical skills and talent.
    In addition, we mustn't forget that NASA science is much 
more than the probes we send into space. It's also the advanced 
technology, the innovative scientific ideas generated under the 
research and analysis programs, the theoretical research, the 
analysis programs that turn mission data into scientific 
results, and the supporting infrastructure necessary to enable 
the inspiring and ambitious work that NASA Science Mission 
Directorate carries out.
    We in Congress, and particularly in this Committee, have an 
important oversight responsibility here. We need to ask hard 
questions about cost, management, credibility, and scientific 
return on investment. And NASA needs to give us substantive 
answers.
    But I hope today that we can also talk about how to keep 
NASA Science whole as we navigate these issues.
    Because we need to ensure that we do not lose sight of the 
big picture. We, as a nation, make the investment in 
fundamental space and Earth science at NASA because we know the 
inherent value in doing so. The missions and programs of NASA's 
Science Mission Directorate are based on the highest-priority 
science questions identified in the consensus-based decadal 
survey processes. They help us learn about the fundamental 
nature, origins, and evolution of the Earth, Sun, solar system, 
and universe, and how humanity fits into all of it.
    We must preserve and bolster NASA's ability to keep 
developing the ambitious missions, sustain supporting research 
capabilities, and pursuing the highest-priority decadal survey 
science while also finding ways to improve cost and schedule 
performance and transparency, particularly of the largest 
missions. It is critical that we get this right.
    Thank you, and I yield back.

    Chairman Babin. And now I would like to introduce our 
distinguished panel of witnesses today. Our first witness today 
is Dr. Nicky Fox. Dr. Fox serves as the Associate--is the 
Associate Administrator for NASA's Science Mission Directorate 
where she oversees the directorate's portfolio of over 100 
individual missions. Previously, she served as the Director of 
the Science Directorate's Heliophysics Division. Prior to 
joining NASA, Dr. Fox worked as the Chief Scientist for 
Heliophysics at Johns Hopkins University's Applied Physics 
Laboratory. During her time at the Applied Physics Lab, Dr. Fox 
also served as the Project Scientist for NASA's Parker Solar 
Probe. We're looking forward to hearing from you this morning.
    Our next witness is Mr. George Scott, who I'd like to 
welcome back to the Committee. You did a great job with Patton 
a few years ago, too. I just wanted to let you know. I guess 
that shows my age. Nobody's seen the movie about George Patton. 
Mr. Scott serves as the Acting Director General for NASA. He 
assumed the role in January of this year, having previously 
served as the Deputy Inspector General. Prior to joining NASA, 
Mr. Scott spent over three decades at GAO, which included 
serving as the Managing Director of GAO's Homeland Security and 
Justice Team. Thank you for being here, sir.
    Our third witness is Dr. Jonathan Lunine, who serves as the 
David C. Duncan Professor in the physical sciences and Chair of 
the Department of Astronomy at Cornell University. He is also a 
member of the National Academy of Sciences and has chaired or 
co-chaired numerous advisory and strategic planning committees 
at the Academy and also at NASA. This includes chairing the 
Giant Planet Systems Panel for the 2023 Planetary Science and 
Astrobiology Decadal Survey. Dr. Lunine is also a co-
investigator on NASA's Juno mission and previously served on 
the Science Working Group of the James Webb Space Telescope.
    And our final witness today, no stranger in here, is Mr. 
Thomas Young, the former Director of NASA's Goddard Space 
Flight Center. Is also the former COO (Chief Operating Officer) 
of Martin Marietta and Chairman of SAIC. Mr. Young began his 
career at NASA's Langley Research Center. Throughout his 20-
plus years of service to NASA, Mr. Young has held various 
roles, including the Deputy Director for NASA Ames Research 
Center prior to his time at Goddard. He is a member of the 
National Academy of Engineering and a former member of the NASA 
Advisory Council.
    So I would like to now recognize Dr. Fox for 5 minutes for 
your opening statement, your testimony. Thank you.

                  TESTIMONY OF DR. NICOLA FOX,
                    ASSOCIATE ADMINISTRATOR,
                  SCIENCE MISSION DIRECTORATE,
         NATIONAL AERONAUTICS AND SPACE ADMINISTRATION

    Dr. Fox. Thank you so much. Chairman Babin, Ranking Member 
Sorensen, and distinguished Members of the Subcommittee, thank 
you so much for the opportunity to appear here today. It is 
always great to have a chance to talk about NASA's science 
program.
    NASA's efforts to address fundamental questions about the 
universe and humanity's place continue to advance the United 
States' role as a global science leader. As you know, NASA 
released our Fiscal Year 2025 budget request, which includes 
$7.565 billion for the Science Mission Directorate. This 
request supports over 125 space science missions, including 54 
that are preparing to launch in the next few years, and over 70 
that are in operation. The request funds U.S. scientists and 
universities, industry and government labs through more than 
4,000 openly competed research awards.
    The missions and the science undertaken by NASA are 
informed by the priorities laid out by the National Academies, 
but funded by you, of course, the Congress on behalf of the 
American people. We're grateful for the Congress' continued 
support of space science, which has produced some stirring 
successes, and I'm just going to highlight a few because I only 
have 5 minutes.
    As we enter its second year of operation, the James Webb 
Telescope continues to provide breathtaking results, with each 
captivating new image leading us closer to unlocking the great 
secrets of our cosmos. The OSIRIS-REx, as you noted, delivered 
samples from the asteroid Bennu to the Johnson Space Center, 
and these pristine samples are more than twice the requirement 
that was returned are effectively time capsules from the 
earliest days of our solar system from like 4.5 billion years 
ago.
    NASA is also adding two missions to its Earth science fleet 
this year. Our first, the PACE (Plankton, Aerosol, Cloud, ocean 
Ecosystem) mission, to study our atmosphere and oceans and the 
ecosystem, was successfully launched from Kennedy Space Center 
on February--in February of this year. And then the second one 
is NISAR (NASA-ISRO Synthetic Aperture Radar) that is our first 
joint mission, first joint mission for Earth science with the 
Indian Space Research Organization. And the--that's going to 
scan the Earth in kind of minute detail down to about a 
centimeter resolution with our first-of-a-kind dual band radar.
    Our investments in Commercial Lunar Payload Services, or 
CLPS, are beginning to bear fruit, the first company in the 
world to make a successful soft landing on the Moon was 
American. We're very proud of them. And it carried NASA and 
commercial payloads to the Moon's South Pole region.
    This has also been a big year for the Heliophysics 
Division. We noted two major solar eclipses, the first one very 
unusual, an annular solar eclipse that occurred in October when 
you would have needed those glasses for the whole thing. In--
coming up from Texas all the way up to Maine, as you noted on 
April 8, we hope you find a way to join us. Now we've given you 
glasses, so you're all set to go. Eyes will be well-protected. 
And if you cannot get yourself to totality, fear not. NASA 
science will bring totality to you.
    Our Biological and Physical Sciences Division just 
presented their initial decadal response to the Academy as we 
drive forward with more and more discoveries about living and 
thriving in deep space.
    Later this year, as you noted, Parker Solar Probe, the 
coolest, hottest mission under the Sun, will make its closest 
approach to the Sun. It will do its seventh Venus flyby, and it 
will go closer to the Sun than any spacecraft has ever come to 
a star. And we're also approaching solar maximum, which offers 
science opportunities related to the space weather hazards.
    We look forward very much to the launch of Europa Clipper 
later this year in October. Clipper will search one of 
Jupiter's moons, the Europa moon, for what we believe is a vast 
ocean that may hold evidence of life.
    We continue our work to protect the planet from asteroids 
with our NEO Surveyor, which is expected to launch in 2028, and 
both Clipper and Surveyor are a joint NASA Center and JPL (Jet 
Propulsion Laboratory) efforts.
    Work continues on the Roman Space Telescope, which is a 
NASA observatory designed to settle essential questions in the 
areas of dark energy, exoplanets, and infrared astrophysics. 
And we look forward to maturing the technologies that will be 
necessary to someday see planets that may harbor life.
    There are also challenges to overcome, as you've 
highlighted, our mission to return samples from the surface of 
Mars has proven to be more costly than initially expected. In 
September, an independent review of the Mars Sample Return 
program provided sobering analysis of the costs and challenges 
associated with this mission. This spring, NASA will complete 
an internal assessment of the mission architecture options and 
will inform the path forward and allow us to provide final 
details for this--for the planetary science budget.
    NASA takes very seriously our responsibility to manage a 
very diverse portfolio within cost and schedule commitments. We 
continue to learn from our experiences, and we have instituted 
new policies to ensure we're constantly improving our ability 
to manage cost and schedule. It's our willingness to 
acknowledge these challenges and overcome them to conduct 
science in ways that have barely been imagined that makes us 
NASA.
    So thank you once again for inviting me to appear before 
you today, and I'm really looking forward to answering your 
questions.

    Chairman Babin. Yes, ma'am. Thank you very much, Dr. Fox.
    And now I'd like to recognize Mr. Scott for 5 minutes for 
his testimony.

               TESTIMONY OF MR. GEORGE A. SCOTT,
                   ACTING INSPECTOR GENERAL,
         NATIONAL AERONAUTICS AND SPACE ADMINISTRATION

    Mr. Scott. Chairman Babin, Ranking Member Sorensen, and 
Members of the Subcommittee, thank you for inviting me here 
today to discuss NASA's Science Mission Directorate. My 
testimony focuses on key challenges the agency faces in 
managing its science portfolio, including developing accurate 
and timely estimates, funding and stability, and workforce 
capacity issues.
    Throughout its history, NASA has been at the forefront of 
incredible scientific discovery, and the agency continues to do 
the unexpected. For example, the Mars Ingenuity helicopter, the 
first aircraft to fly under its own power on another planet, 
surpassed 2 years of operations and completed 72 flights.
    Despite its long history of success, some of NASA's most 
impressive scientific missions, the Hubble telescope, the 
Curiosity rover, and the James Webb telescope, all experienced 
significant cost increases and schedule delays. The extra 
funding and time needed not only impacted these missions, but 
also created cascading effects across the agency's science 
portfolio.
    As we have frequently reported, NASA struggles to establish 
complete, credible, and transparent estimates. This is 
particularly true when it comes to large, complex missions. 
NASA's history of setting unrealistic costs and schedule 
baselines is due in part to the agency's culture of optimism. 
As we said over a decade ago, a culture of optimism and can-do 
spirit are essential for realizing groundbreaking scientific 
achievements and overcoming extraordinary technical challenges. 
That said, the same optimism may prevent leaders from 
critically assessing costs, risks, and schedules to determine 
what can realistically be accomplished within a set budget and 
timeframe.
    To its credit, NASA has taken some actions to address its 
cost and schedule challenges. For example, in 2020 SMD 
completed its Large Mission Study that examined how the agency 
makes critical decisions that impact mission and program 
success. However, NASA has yet to incorporate the 
recommendations from the study into its practices and guidance 
for flagship missions. Also in 2020, the agency established the 
Chief Program Management Officer position to strengthen 
oversight and implementation of program management policies and 
best practices.
    Funding instability remains a concern. Unstable funding, 
whether in terms of the total amount of funds allocated to a 
project or the timing of when those funds become available, can 
contribute to poor outcomes. For example, inadequate funding 
early in a project can decrease management's ability to 
identify and address key risks early on. In other cases, moving 
tasks to later in the project may require managers to keep a 
larger workforce than originally planned, also resulting in 
increased costs. There's also the instability resulting from 
appropriations that lock the agency's funding at the previous 
year's level for extended periods. These uncertainties further 
compound the difficulties in effectively managing projects.
    Workforce capacity remains an issue for NASA. We have 
identified attracting and retaining a highly skilled and 
diverse workforce as a top management challenge for the agency. 
As early as 2018, we highlighted workforce capacity issues at 
the Jet Propulsion Lab. We are similarly concerned that other 
centers face the same challenge. For example, the Goddard Space 
Flight Center faces a heavy workload with large projects that 
are competing for a limited number of technical workers, even 
as these missions plan to launch in the next 3 to 5 years.
    NASA has repeatedly demonstrated its ability to overcome 
significant hurdles to accomplish amazing things. However, 
these achievements have often taken longer and cost much more 
than planned. Many of the agency's science missions are 
ambitious endeavors, and they need to be grounded in more 
realistic assumptions and estimates. Without this, it will be 
difficult for Congress to make informed decisions about NASA's 
long-term funding needs. Likewise, the agency will lack 
information needed to make difficult decisions on how best to 
allocate limited funds and prioritize future missions.
    We will continue to support NASA in achieving its 
scientific goals, while ensuring transparency and 
accountability for these efforts. Thank you.

    Chairman Babin. Thank you, Mr. Scott. And I'd now like to 
recognize Dr. Lunine for 5 minutes to present his testimony.

              TESTIMONY OF DR. JONATHAN I. LUNINE,
                 THE DAVID C. DUNCAN PROFESSOR
          IN THE PHYSICAL SCIENCES, CORNELL UNIVERSITY

    Dr. Lunine. Thank you very much. Chairman Babin, Ranking 
Member Sorensen, and distinguished Members of the Subcommittee, 
thank you for the opportunity to present my views on the status 
of NASA's Science Mission Directorate.
    It is difficult not to feel passionately patriotic and 
proud of what our Nation has accomplished in space science. As 
a scientist and academic whose entire career has been spent 
working on NASA programs, I am grateful to have participated in 
the development and execution of some of the greatest space 
science odysseys ever undertaken: the Voyager flyby of distant 
Neptune, the Cassini exploration of Saturn, the ongoing Juno 
mission of Jupiter, the Europa Clipper mission set to launch 
this October, and the James Webb Space Telescope.
    The accomplishments of our Nation's space science program 
over the past quarter century are too numerous to recount, but 
we've all tried to list a few of them at least, and I'll try my 
hand at this as well: the discovery of an ocean capable of 
sustaining life in two moons in the outer solar system, at 
least Europa, Jupiter and Enceladus at Saturn; the first 
exploration of the Sun from inside its atmosphere; the probing 
of evermore ancient epochs of the universe with Hubble and 
Webb, and much, much more.
    And the investment in space science that the United States 
has made over the decades is paying off in unexpected ways. For 
example, the Webb telescope is teaming up with other space 
telescopes like the Chandra X-ray Observatory to give us 
unprecedented views of cosmic processes over a vast range of 
the electromagnetic spectrum from X-rays to the infrared.
    I want to turn now to Mars where the Nation's prowess in 
space technology will be most on display in the coming decade. 
Two incredibly capable rovers designed and built with American 
technology by NASA's Jet Propulsion Laboratory have been 
roaming the Martian surface over the past decade in search of 
the clues to how Mars went from being a very Earthlike world to 
one that today is inhospitable. This is a profound question 
because its answer may well tell us how fragile the 
habitability of our own planet might be. How did Mars dry up? 
Exactly when? Did life begin on Mars and then die off?
    As articulated by NASA advisory groups in two successive 
decadal surveys of the National Academy of Sciences, answering 
these questions will require bringing samples back to Earth. 
Both planetary science decadal surveys identified Mars Sample 
Return as their highest priority. Why so? As we learn more 
about Mars and ask more detailed questions, instruments of 
increasing sensitivity, resolution, and sophistication are 
required, eventually exceeding what can be plausibly carried in 
a spacecraft. In laboratories on Earth, powerful analytic 
techniques can detect faint clues to the earliest history of 
Mars and to the possible presence of traces of ancient life.
    It is not enough to have these sophisticated geochemical 
tools in the laboratory. The samples must come from a place on 
Mars that was once Earthlike. NASA's Perseverance rover is in 
such a place right now, Jezero Crater. At the crater's western 
end is a dried-up river channel and an enormous delta-shaped 
fan of sediments deposited at the time that that river ran. 
This one complex region holds the potential for answering a 
host of questions about the geologic and climate evolution of 
Mars, and Perseverance is collecting samples carefully selected 
to provide those answers. But to realize that potential 
requires getting those samples back to Earth.
    Mars Sample Return is the most ambitious robotic program 
ever attempted, bar none. Much of the technology is new and 
challenging. Having served as a member of the second MSR 
Independent Review Board (IRB), I am supremely confident that 
it can and will be done. It can be done because American 
engineering prowess is up to the task. It will be done because, 
as a Nation, we surely will not simply walk away from a daring, 
highly visible, and scientifically important challenge.
    In closing, let me point out that more than a half century 
after the first Moon rocks were returned by the Apollo 
astronauts, science is still being done on them today by 
instruments far more capable than those available in 1969 when 
I was 10 years old. The samples returned from Mars in the 
coming decade will be analyzed not only by scientists alive 
today, but by scientists who are not yet born using laboratory 
techniques that are not yet invented. These precious records of 
early Mars will be a lasting scientific treasure and the legacy 
of American technological prowess.
    Thank you very much for having me here today.

    Chairman Babin. Thank you very much for your testimony.
    I would now like to recognize Mr. Young for 5 minutes. 
Thank you.

       TESTIMONY OF MR. A. THOMAS YOUNG, FORMER DIRECTOR,
        GODDARD SPACE FLIGHT CENTER AND FORMER PRESIDENT
                 AND COO, MARTIN MARIETTA CORP.

    Mr. Young. Chairman Babin, Ranking Member Sorensen, 
Committee Members, I'm pleased to have the opportunity to 
present my views on NASA's Science Mission Directorate.
    Great organizations achieve great accomplishments. NASA's 
Science Mission Directorate has a legacy of great 
accomplishments. My examples of great accomplishments by SMD 
are Viking, Hubble, James Webb Space Telescope, and hopefully, 
Mars Sample Return. Others might select a different set with 
equal merit. It would also be a mistake not to recognize the 
incredible contribution of projects from the sounding rocket 
and balloon program to projects such as Parker Solar Probe and 
weather satellites.
    What are the characteristics of projects that result in 
great accomplishments? Today, projects such as JWST and MSR 
originated from decadal surveys. The National Academies' 
decadal surveys are comprehensive surveys of a scientific 
discipline such as astronomy and astrophysics to identify the 
No. 1 priority project for development by NASA. The surveys 
provide a mechanism for the scientific community to speak with 
one voice in identifying the best of the best.
    Projects that result in great accomplishments travel 
extremely difficult development paths. Projects in this 
category push the boundaries of what is possible. This 
aggressive approach is necessary to obtain extraordinary 
scientific results such as JWST results that are being 
experienced today.
    The difficult developmental path these projects follow are 
populated with incredible engineering, cost, and management 
challenges. Most, if not all, are threatened by cancellation.
    So what are the keys to the success of these projects that 
must test the limits of what is possible? Clearly, the 
exceptional people that make up the project organizations in 
NASA, academia, and industry are key. Superior leaders are 
required to provide bold and visionary leadership, leadership 
that recognizes corrective action and not cancellation is 
necessary to achieve great accomplishments.
    The scientists, engineers, and leaders do not simply walk 
in off the street. They're a result of rigorous hands-on 
development and being trusted with significant early career 
responsibilities. NASA has a history of exceptional employee 
development. This development effort will be even more 
important as SMD pursues more challenging projects in the 
future.
    Next, I would like to discuss MSR. Today, MSR is in the 
balance as to whether it will be allowed to follow the path 
necessary to become an SMD great accomplishment, or will it 
become a monument to a missed opportunity? I do not want to 
minimize the technical cost and management problems identified 
by the Independent Review Board. The problems are significant, 
as are NASA's and our country's budget challenges.
    MSR is identified as the No. 1 priority in the past two 
planetary decadal surveys. The expectation is clear, that when 
the samples are analyzed in the highly capable Earth-based 
laboratories, MSR will join the SMD legacy great 
accomplishments. Today, the future of MSR is in the hands of 
NASA, congressional, and Administration leaders. Bold, 
visionary leadership is needed to put MSR on a path to success.
    The future of SMD is populated with incredible 
opportunities. Many are focused upon civilization's great 
question: Are we alone? We must continue to improve our project 
management capabilities to realize the potential that the 
future holds. My thoughts on some of the required improvements 
are cost estimating. Better cost estimating of most probable 
cost and not relying upon lowest credible costs for early 
decisionmaking is required.
    Systems engineering: Improved systems engineering is needed 
to develop architecture and interfaces that are the simplest 
possible to achieve project objectives.
    Employee development: Developing scientists, engineers, and 
leaders will continue to grow in importance. Contracts with 
industries that focus upon buying services as opposed to 
hardware, systems integration, operations, et cetera, minimize 
development opportunities.
    SMD strategy: A balanced SMD strategy is a worthy 
objective. However, implementing projects such as Viking, 
Hubble, JWST, and MSR will likely not be possible without 
accepting some impact on other activities. This should be 
acceptable to accomplish great accomplishments.
    Project management: Future projects will require the full 
capabilities of NASA. This includes NASA senior management, the 
Science Mission Directorate, and the NASA centers, including 
center directors, project managers, and their respective 
organizations.
    The hallmark of a great organization is the willingness to 
accept difficult challenges to achieve great accomplishments. I 
believe SMD is such an organization and that the future of SMD 
will be bold, exciting, scientifically rewarding, and a source 
of great national pride.
    Thank you very much.

    Chairman Babin. Thank you. I appreciate all of you 
witnesses for your testimony.
    And now I would like to recognize myself for questions for 
5 minutes.
    Dr. Fox, NASA stood up an internal group to develop a 
response to the second independent review team's assessment of 
the Mars Sample Return program. When will NASA be prepared to 
share the results of this internal review with Congress? We 
want it to be successful.
    Dr. Fox. Thank you so much for the question. We are 
wrapping up the--putting together the results. They will be 
available in the spring. And so--but literally, as soon as we 
can get them to you, we will.
    Chairman Babin. Good. Today, I think, is the first day of 
spring. You don't have it ready yet, huh?
    Dr. Fox. Spring's a lovely term.
    Chairman Babin. All right. All right. Well, thank you.
    Congress--also for you, Dr. Fox, Congress directed NASA to 
discover and characterize at least 90 percent of the Near-Earth 
Objects, or NEOs, that could cause significant damage if they 
collide with Earth. NASA is years behind the deadline that 
Congress set to complete this survey, which is one of really 
the only--one of the few tasks that NASA is directed by law to 
complete. The NEO Surveyor mission is an important part of 
completing this survey. And what is the status of the NEO 
Surveyor mission?
    Dr. Fox. Happy to say that NEO Surveyor is on track. It 
will launch in 2028, and we really do appreciate the support 
that we've had to keep that mission funded through even this 
challenging year. So NEO Surveyor is looking good.
    Chairman Babin. Good deal. Thank you.
    Mr. Young, in September 2020, NASA's Office of Inspector 
General, the OIG, released a report on NASA's planetary science 
portfolio. The report highlighted NASA's challenges in adhering 
to Discovery-class mission cost caps. In particular, the report 
stated that even when excluding launch vehicle and operations 
costs, none of the Discovery missions are under the $500 
million cost cap. What are the consequences of breaching a cost 
cap? Does a tolerance for cost-cap breaches have an impact on 
program discipline for future Discovery-class missions? And how 
are other non-Discovery-class missions in the pipeline going to 
be impacted when these cost caps are breached?
    Mr. Young. Well, I think you summarized it pretty well. 
That will happen. It's important to look back as to why the 
cost breaches. And one of the items is that we continually, for 
good scientific reasons, select more and more challenging 
opportunities. And as we do push technological limits, we are 
in a circumstance where a priori understanding of the precision 
of the cost is just not there. So I think that, you know, if we 
wanted to have less testing of the cost or the schedule limits, 
it really says select projects that are less challenging. The 
problem with that is they're also less rewarding, and so it's a 
difficult circumstance, and it's one that that Nicky and her 
organization have to really balance. But what you described is 
true. If they're all increasing in cost, they're going to push 
something else out that's not going to----
    Chairman Babin. That's right.
    Mr. Young [continuing]. Be able to fit into the project--
into the budget. But----
    Chairman Babin. OK.
    Mr. Young [continuing]. On the other hand, testing where 
you get the best return for the amount of money that is 
expended is something that deserves an awful lot of scientific 
analysis and systems engineering analysis before projects are 
implemented.
    Chairman Babin. Thank you. Mr. Scott, in February 2024 
NASA's Office of Inspector General issued a report on the Mars 
Sample Return, or the MSR program, as we've heard several times 
today. The report noted that characteristics intrinsic to big 
and complex missions like the MSR program are hard to quantify 
in estimates but can drive project costs upwards throughout 
development. The report stressed that NASA must consider these 
intrinsic characteristics and cannot attribute past cost growth 
to inflation, the COVID-19 pandemic, or to supply chain issues. 
Can you describe these intrinsic characteristics of large 
missions and their effects on the cost program?
    Mr. Scott. Thank you, Mr. Chairman.
    Chairman Babin. Or the program costs rather.
    Mr. Scott. Thank you, Mr. Chairman. Yes, as we've discussed 
already in the statements, just a number of factors continue to 
drive the cost increases in large programs like the Mars Sample 
Return, whether it's the initial baseline estimates either 
provided by the decadal, which are early on and often lack the 
complete picture of what some of these missions will cost. You 
know, there's also workforce issues that can end up driving the 
cost--increased cost for these missions. The lack of maturity 
of some of the technology is also a key driver in some of these 
large, complex missions. That's why we think it's important for 
NASA to start to implement some of the recommendations from the 
Large Mission Study to better inform going forward where you 
put the attention early on in these large projects.
    Chairman Babin. OK. Thank you. And it looks like I'm out of 
time, so I'd like to recognize the Ranking Member, Mr. 
Sorensen.
    Mr. Sorensen. Thank you, Mr. Chairman.
    I'll begin with Dr. Lunine. Last year, I was able to 
welcome NASA Astronaut Dr. Kate Rubins to my district. And over 
the course of 2 days' time, we visited numerous schools. And it 
was really great to hear her explain the importance of what we 
are learning from the Apollo mission and what we were able to 
bring back from the lunar surface. Could you please expand on 
what scientists will be able to learn with the samples that we 
hope to get back from the Mars surface?
    Dr. Lunine. Sure, thank you very much for the question. 
The--to answer that question, I will go into my hourlong 
lecture, but since I don't have that time----
    Mr. Sorensen. Four minutes and 10 seconds.
    Dr. Lunine. Yes, I'll give you four points. So, first of 
all, we do not have a chronology of the early history of Mars 
that's on an absolute timetable. That is, we know the relative 
times that events happened but not the absolute times. And for 
the Earth and the Moon, the Apollo samples gave us that for the 
Earth-Moon system. That was one of the most profound scientific 
accomplishments of Apollo, to know the dates that things 
happened. And so we'll learn that for Mars from those samples 
from what's called radiometric dating. And that can be done--
really needs to be done in terrestrial laboratories because you 
have to be able to look at what are called multiple isotopic 
systems to do that, so I'll leave it at that.
    Second, we will learn about the question of whether organic 
molecules were present with the water and what the nature of 
those organic molecules were. You can detect some organic 
molecules on Mars itself, but it's a very faint signature, and 
to be able to detect molecules that are not well-preserved 
requires instruments that can detect abundances that are well 
below what you can bring to Mars.
    No. 3, of course, question of life and whether there are--
is fossil evidence of life. The experience of geologists on the 
Earth with very ancient life is that it requires laboratory 
instruments to find the chemical and physical clues because 
those clues over billions of years have become very, very 
faint, and the same for Mars.
    And the third is that because the crater that Perseverance 
is in is formed by an impact, it excavates material from deeper 
under the crust. And so to be able to sample that material and 
bring it back to Earth and determine the mineralogy of that 
material is an outstanding opportunity to know what's 
underneath the dusty surface of Mars. And I'll leave it at 
that.
    Mr. Sorensen. Yes. Thank you for sharing. You could 
probably talk for a long time on this subject.
    Dr. Lunine. I could, yes, that's true. Yes.
    Mr. Sorensen. I do want to go to Dr. Fox. Let's bring this 
back to our planet. The Landsat satellite system has provided 
continuous land imagery of our globe for 50 years, not just as 
a meteorologist have I use this data, but the University of 
Illinois has utilized this in agriculture. And then also I'd be 
remiss if--most of us on Capitol Hill are a little bit raspy 
today because of the fires out in western Virginia or the fires 
in the western part of the Chairman's State of Texas. How will 
NASA's development of the next generation of Landsat 
satellites, Landsat Next, be important for districts like ours?
    Dr. Fox. That's a wonderful question. And I, like Jonathan, 
could give you an hour lecture. But, I mean, Landsat is a 
critical part of, I mean, our complete Earth monitoring system. 
And, as you note, you know, wildfires do not follow boundaries. 
They don't follow State boundaries. We all breathe the same 
air, as we found last year from the Canadian wildfires.
    So a lot of our new missions, Landsat clearly, you know, 
set to take that next step, next step for Landsat Next. It's 
really a different generation of Landsat. It--also, I would be 
remiss if I didn't mention our Surface Biology and Geology 
Mission that will also just give us these unprecedented views 
of what--you know what we are doing. We just launched PACE, and 
that is not only telling us about ocean health, but also about 
the health of the air that we breathe. So Landsat, clearly a 
very key part, but it really is in this sort of strength of 
bringing all of these diverse measurements together to really 
allow us to do a great job of characterizing our planet.
    Mr. Sorensen. I want to be cognizant of time, so really 
quickly, Mr. Young, you stated that there are difficult 
development paths. The projects that result in great 
accomplishments travel extremely difficult development paths. 
What do you think we in Congress need to do to consider when we 
are looking at these projects at?
    Mr. Young. Well, I have a quick summary. I would say that 
we need to look at the difficulties that have occurred and 
apply lessons learned to the next series that exist. And that 
is, I think we know that we've got issues in cost estimating. 
We've got issues in systems engineering. We've got issues in 
developing the required talent to implement these programs. And 
we need to very clearly specify them and have a coordinated 
effort to improve significantly in order to be able to do the 
challenging things that are in front of us in SMD.
    Mr. Sorensen. Thank you. Learn from the past to make good 
decisions for the future.
    Mr. Young. Absolutely.
    Mr. Sorensen. Thank you, Chairman.
    Chairman Babin. Thank you.
    I'd like to recognize the gentleman from Florida, Mr. 
Posey.
    Mr. Posey. Thank you very much, Chairman Babin. And I want 
to thank the witnesses for your illuminating testimony today, 
very, very much appreciated.
    Mr. Scott, has the way NASA managed its high-end computer 
capabilities hampered at all in any way that you know its 
ability to properly monitor the foreign national accreditation 
access process?
    Mr. Scott. Thank you, Mr. Posey. As we recently reported, 
we did raise issues about the 700-plus foreign nationals that 
today have been identified accessing the high-end computing 
capabilities. Again, the issues that came to light were one of 
the ability to better understand the number of high-end 
computing--high-end computing systems NASA has running, it's 
diffuse, spread out across the various centers, and being able 
to better understand and track and monitor who's actually on 
the system and ensuring that these diffuse systems have the 
adequate cybersecurity controls.
    Mr. Posey. Thank you. Do you think the use of NASA's high-
end computing by external and foreign national parties is as 
persuasive as the Inspector General's report might have 
indicated?
    Mr. Scott. Again, we've asked NASA to set up a tiger team 
to look and better understand the number of external users and 
foreign nationals accessing the system, right? It's a both/and, 
right? It's important for scientific reasons that folks have 
access to the high-end computing, and it's equally important 
that we understand who these folks are, what they're accessing, 
and being able to track and monitor their use of the systems.
    Mr. Posey. Thank you. Of the more than 700 foreign 
nationals the IG report says have accessed this system, are you 
aware of any from any country of concern such as China or the 
cities of Macao or Hong Kong?
    Mr. Scott. I'm not aware of any foreign national--from any 
countries of concern. NASA does have a foreign national 
accreditation process, and so my understanding is the folks on 
the system have gone through that process. What we're asking 
NASA to do is ensuring--to better ensure that the folks 
responsible for the high-end computing capabilities are part of 
the accreditation process and, again, making sure these systems 
are up-to-date in terms of their cybersecurity controls and 
we're able to monitor the activity of those on the system.
    Mr. Posey. That's great.
    Has NASA expeditiously implemented the recommendations in 
the Inspector General's report?
    Mr. Scott. We're awaiting their responses. We believe that 
their initial responses will address the recommendations we 
made, but again, we're waiting to see exactly when they're 
implementing the various recommendations.
    Mr. Posey. OK. Dr. Fox, is NASA working to fully implement 
the Inspector General's recommendations concerning high-end 
computer capabilities to restrict access by external and 
foreign national parties?
    Dr. Fox. NASA really appreciates the receipt of the report 
from the Inspector General's Office, extremely helpful report. 
We are in the process of implement--of responding to each of 
the recommendations and putting together the team as requested 
to actually do this deep-dive study.
    Mr. Posey. OK. Mr. Chairman, I ask unanimous consent to 
include in the record the March 2024 NASA's Office of Inspector 
General report.
    Chairman Babin. Without objection, so ordered.
    Mr. Posey. Thank you, Mr. Chairman. I yield back.
    Chairman Babin. Yes, sir. Thank you.
    And now I'd like to recognize the gentlewoman from 
Virginia, Ms. McClellan.
    Ms. McClellan. Thank you, Mr. Chairman.
    As the only Member of the Committee from Virginia, I'm 
particularly proud of the work being done at Langley Research 
Center, which I've had the opportunity to visit, their work to 
advance science not only in the Commonwealth, but around the 
country.
    And I have to say that, as a mother to a son who wants to 
be an astronomer, he's a keen fan of the work that you all do 
in the Planetary Science and Helioscience Divisions. He has 
used images from the Hubble and James Webb Space Telescope for 
school presentations and is a junior volunteer at the Science 
Museum of Virginia. And those images have sparked an interest 
in STEM (science, technology, engineering, and mathematics) 
more than anything that his father and I have ever put in front 
of him. And I am very hopeful that he will one day be one of 
those scientists that Dr. Lunine talked about who will be 
studying samples brought back from Mars.
    And thank you very much for the glasses because he told me 
the other day that we needed special glasses because he's very 
much looking forward to the eclipse. So you have definitely 
gotten me some cool points today.
    We know that funding stability is essential to maintaining 
a highly skilled workforce, which enables our continued 
national leadership in research, innovation, and exploration. 
And Dr. Fox and Mr. Scott, could you tell us if the President's 
Fiscal Year '25 budget request sufficiently funds the Science 
Mission Directorate to prevent future workforce reductions or 
some of the challenges you've discussed today?
    Dr. Fox. Thank you very much. I'll be happy to yield an 
extra pair of glasses for your son----
    Ms. McClellan. Thank you.
    Dr. Fox [continuing]. To be sure that he's protected, too.
    We're very grateful for the President's budget request, the 
Fiscal Year 2025 President's budget request that does fund NASA 
at $7.565 billion for science. That is below the enacted 2023, 
so it does provide challenges in the portfolio. The bulk of 
those challenges are in the Planetary Science Division, as you 
noted, and we are working very closely with our centers, with 
our teams to try and limit the impact of those reductions.
    Ms. McClellan. And can you tell me what strategies NASA is 
implementing to prevent attrition and ensure the stability of 
your workforce?
    Dr. Fox. Again, we're working extremely closely with the 
centers to understand any impacts of the various challenges, 
obviously, with Mars Sample Return, with the--following the 
recommendations from the IRB. We did do--we have paused the 
development of some of the aspects of Mars Sample Return while 
we look at all of the architecture, the different architecture 
studies. And so as I know everybody is aware, that did cause 
some workforce losses at the Jet Propulsion Lab, which, of 
course, our hearts go out to anyone who has to do that. But 
that was done as a result of budget limitations there. But we 
are working extremely closely with all of our centers and, of 
course, with JPL to try and minimize and, more importantly, to 
actually sustain the critical workforce that we need to be able 
to do these amazingly daring missions that we want to succeed 
with.
    Ms. McClellan. And could you discuss any potential impacts 
to the Science Mission Directorate projects at Langley 
specifically if NASA's top-line fund either remains flat or 
these cuts take place?
    Dr. Fox. I don't have a full--so we--let me start again. So 
for Langley, the biggest impact will be in the Earth Science 
Division because of some of the delays and the change and the 
way that we will be implementing some of the Earth science 
missions, so there will be some impact to Langley there. They 
also do have critical work with us in Mars Sample Return, and--
but they do--also have worked with Dragonfly, which is well-
funded, and so we're hoping to be able to balance between some 
of the missions that have--that are more robustly supported and 
some that may be a little skinny down in the Fiscal Year 2025 
plan.
    Ms. McClellan. OK. And in my remaining time, you may not be 
able to answer this here, so I'll submit this for the record, 
but your Bridge Program that develops partnerships between your 
centers and institutions that are historically under-resourced 
like minority-serving institutions, community colleges, and 
tribal colleges, I wonder if you could, for the record, provide 
an update on the status of the Bridge Program and some of its 
outcomes?
    Dr. Fox. We'd be very happy to provide that for the record. 
I know the time's done, but I will say we are really, really 
excited about our Bridge Program for all the reasons that you--
it's always nice to be able to offer people opportunities, but 
to be able to actually support them to be able to take 
advantage of those opportunities is what we're doing with our 
Bridge Program, so thank you for the question.
    Ms. McClellan. Thank you. Mr. Chairman, I yield back.
    Chairman Babin. Yes, ma'am. Thank you very much.
    I'd like to recognize the gentleman from California, Mr. 
Garcia.
    Mr. Garcia. Thank you, Mr. Chairman. Thank you all for 
being here, to all the witnesses, and your contributions to the 
country and to science and to our Nation's security.
    You won't find a bigger fan on the Hill of NASA and the 
private-public partnerships that we're enjoying. This is a true 
space renaissance. And I should say that with all deference, 
Mr. Chairman, you probably are just as big a fan of NASA and 
the private partnership as I.
    And so, you know, this is not coming from a place of being 
combative, but trying to be cooperative in the spirit of being 
successful for these missions, especially the science and 
national security implications that a lot of these missions 
carry with them. And while I appreciate the eclipse sunglasses, 
I would have preferred a set of glasses that would have 
prevented me from being blindsided by the actions that the 
Administration has taken over the last few months when it comes 
to the Mars Sample Recovery program.
    Mr. Young said that the fate of MSR is in the hands of 
NASA, as well as Congress, and I disagree with that. It 
certainly doesn't feel that way. I think we have a better 
relationship than what I think you assumed. And you left us in 
the dark, frankly, with some reprogramming that took place 
under loopholes during the CR (continuing resolution).
    As the authorizer on this Committee and as the appropriator 
on CJS (Commerce, Justice, Science), I would have really 
appreciated a heads-up that we were going to lay off close to 
600 employees at JPL before that decision was made. I was aware 
of before it was executed, but not before that decision was 
made. And we have caused irreparable damage in those decisions. 
And I understand that the Senate mark was at $300 million and 
ours was $975 million, and we were in the midst of a CR, and 
there's a lot of uncertainty and ambiguity there. And as a 
former, you know, program director myself of $100 million 
programs, I understand that that uncertainty is not good.
    But we could have cooperated, we could have communicated, 
and we could have landed on a place where maybe we should have 
preserved those jobs. And what's happening now is those folks 
that were at JPL aren't just leaving JPL, they're leaving the 
industry. In many cases, they're leaving the State, and we're 
losing a cumulative of anywhere between 3,000 years and 5,000 
years of corporate knowledge of engineering and design and 
early development design work expertise that ain't coming back. 
And so I don't know how we're going to address the workforce 
issues.
    It was a premature decision. It was prior to the IRB 
Response Team recommendations that we're expecting here in the 
spring. And I understand you can drive a truck between the $300 
million and the $975 million or so that the House marked, too, 
and that's uncertainty. And I definitely have received your 
message that CR's are bad, but I think you exploited that. I 
think you exploited loopholes in the C.R. language to fund a 
level that is well below congressional intent and certainly 
well below executability level.
    So I've submitted a letter to the Administration, to 
Administrator Nelson with 20 colleagues. By the way, I'm the 
only Republican on this letter, so this is a bipartisan thing 
from California, requesting that you fund MSR at $650 for the 
remaining part of Fiscal Year 2024. I understand that's going 
to require some reprogramming and different profiles on your 
cost expenditures. We'd like to see a response to that. But I 
think we are also asking to not have any other reductions in 
forces, riffs, or layoffs as a result of the decisions already 
made so that we can try to salvage what workforce talent we 
have there as well.
    So I guess, Dr. Fox, my question is, will you comply with 
the direction in the Fiscal Year 2024 spending bill, which 
hopefully will be executed here shortly, to not further reduce 
staff on the Mars Sample Return program?
    Dr. Fox. So thank you for the question. And as you--really, 
thank you for your unwavering support of the Mars Sample 
Return. I really genuinely mean that, and I really do 
appreciate your support on that.
    We did brief Congress a number of times, the 
appropriations, on the plans for Mars Sample Return. I think I 
actually had the pleasure of speaking to you myself.
    Mr. Garcia. I appreciate that.
    Dr. Fox. And, you know, with the uncertainty, if we had 
allowed the spending on Mars Sample Return to continue at--or 
to continue at the 2023 level, we would have reached the Anti--
--
    Mr. Scott. Deficiency.
    Dr. Fox [continuing]. Antideficiency, thank you, 
Antideficiency Act before February. And of course, we did not 
want to in any way do that. So we took the measures to limit 
and to actually follow the recommendations of the Independent 
Review Board.
    Mr. Garcia. I'm running out of time. I want to ask a 
question looking forward. Looking forward for the rest of the 
fiscal year, are you committed to not reducing additional 
staff? And will you commit to allocating sufficient funding in 
Fiscal Year 2024 and 2025 to ensure the timely retrieval of 
samples of Mars? And I want to be very clear. I support you. I 
support NASA and this program, but it's not unwavering. If we 
continue to show premature and, in my opinion, reckless 
behavior patterns at our reprogramming, I will want to do 
deeper dives into the program and ask even more questions. But 
if you can answer the questions for the record, you commit to 
retaining the current staff levels as they are for the rest of 
year moving forward, and in Fiscal Year 2025, continuing to 
follow our congressional intent with funding levels to execute 
the program sufficiently.
    Dr. Fox. So we look forward to the results of the 
Independent Review Team that will be coming out in the spring, 
and we certainly commit to work closely with JPL to continue to 
maintain the critical workforce that will be necessary to do 
these missions.
    Mr. Garcia. OK. I thank you. I'm out of time. I yield back.
    Chairman Babin. Thank you, Mr. Garcia, good questions.
    I'd like to call on Mr. Strong, my friend from Alabama.
    Mr. Strong. Thank you, Chairman Babin, Ranking Member 
Sorensen, and our witnesses for their testimony today.
    I understand two proposals from Marshall Space Flight 
Center were not selected in a recent Science Mission 
Directorate call. These proposals were for concepts called 
MoonBEAM (Moon Burst Energetics All-sky Monitor) and LEAP 
(Large Area Burst Polarimeter). MoonBEAM was the highest-rated 
astrophysics proposal and the only proposal to receive a 
category one rating, the highest rating possible.
    Dr. Fox, Mr. Scott, what is holding NASA back from making 
these competitive awards?
    Dr. Fox. Thank you for the question. There are many factors 
that go into why a mission--why things are selected and not 
selected. And for this particular one, we did not have the 
resources available to be able to support a mission of 
opportunity.
    Mr. Strong. OK. The Mars Ascent Vehicle also just 
successfully finished its performance development review and 
successfully completed wind-tunnel testing at Marshall Space 
Flight Center. The Mars Ascent Vehicle, a crucial element of 
Mars Sample Return program, is a top priority within the 
decadal--I think that's the program they call it--the survey. 
Dr. Fox, Mr. Scott, what is NASA doing to meet its commitment 
to the survey's priorities?
    Dr. Fox. Yes, as you note, it was the highest priority not 
only of the current decadal but of the previous decadal to 
bring our samples back from Mars, as Jonathan also talked 
about. We are--at the moment, we are reassessing. We had that 
Independent Review Board that released their findings last 
October. We are--we have an independent team at NASA that is 
going through each of those findings.
    And so while we're looking at the restructuring that was 
recommended by that Independent Review Board, we do have some 
elements of our Sample Return paused because we are being good 
stewards of taxpayer money, and we don't want to go forward and 
spend money that would then not be realized. So that is the 
plan, but stay tuned. In spring, we will roll out the results 
of that--of the--or the findings of that team and hopefully get 
Mars Sample Return back on a path to be able to bring those 
extremely precious samples back from the red planet.
    Mr. Strong. Thank you. We're anxiously awaiting.
    Marshall Space Flight Center also hosted ISS (International 
Space Station) Payload Mission Control Center, which manages 
many research payloads aboard the ISS. Dr. Fox, how does NASA's 
plan to ensure that researchers can seamlessly transition their 
experiments from the ISS to the commercial LEO (low-Earth 
orbit) destinations as they become available?
    Dr. Fox. That's a great question. I could talk for hours 
about the great stuff that we do on ISS, trust me. But we 
have--we are investing. We're working with our partner 
agencies, with NIH (National Institutes of Health), with the 
FDA (Food and Drug Administration), with the Human Research 
Program, of course, and with BARDA (Biomedical Advanced 
Research and Development Authority), our Biological and 
Physical Sciences Division. I think they have about an $18 
million investment right now in things like tissue chips, so 
growing organs and sending up--I mean, you could actually 
envisage sending up a mini-you on a chip and then looking at 
how you respond to different medications.
    And so being--basically being--planning to do this sort of 
rapid development and working hand-in-hand with our commercial 
partners to look at exactly what it would take to transition 
from this critical science that we do on the ISS and get it 
ready to enact on whichever of the commercial LEO destinations 
that we go with. Obviously, they--when they go up--when they 
put these in space, they want to use them, and so biological 
and physical sciences is a great customer, and we are ready to 
do amazing things, whether it's growing plants, looking at 
yeast and seeds and how they adapt.
    Also, I'll just note, you know, already taking advantage of 
Artemis with flying on Artemis I, flying a biological physical 
payload there, and getting ready to roll out the science that 
we're going to do on Artemis II as well, so just excited about 
the whole thing.
    Mr. Strong. I can tell the excitement in your voice. And I 
thank each of you for being here today and the role that you 
play.
    Mr. Chairman, I yield back.
    Chairman Babin. Yes, sir. Thank you, Mr. Strong.
    And I'd like to call now on our Full Committee Chair, Mr. 
Lucas.
    Chairman Lucas. Thank you, Mr. Chairman.
    And to Mr. Young, when I joined this Committee more than 20 
years ago, the James Webb telescope was in the early stages of 
formulation. And over that period, this Committee engaged in 
extensive oversight of the development of the program. You led 
the Independent Review Board that assessed the status of the 
telescope and testified this--to this Committee about the 
results. From your vantage point, is NASA integrating lessons 
learned from the development challenges of James Webb? And it 
was a challenge.
    Mr. Young. And there were challenges, that's no question. 
In fact, you brought back a lot of interesting memories.
    Chairman Lucas. Oh, absolutely.
    Mr. Young. I would say the answer is yes. You know, NASA 
has put together--and somebody can remind me the name of it--
but a group of people that really went about and talked to a 
lot of people. I was one that spent some time with the group 
and trying to put together lessons learned. And so, yes, I 
think there is an effort, you know, to do that.
    I think the other thing, though, if I could hitchhike on 
your question that I need to really emphasize, and you would 
appreciate this, these missions, the flagship missions that 
we're talking about that are pushing the boundaries of 
capability, they are never going to be easy, and they're never 
going to be free of challenges and difficulties. And I think 
that we've--you know, the results of James Webb, in my view, 
maybe doesn't justify all of the issues that you had an 
opportunity to have a front row seat to, but they really did 
show with--that the perseverance of trying to get all of the 
issues under control, particularly those that were technical 
issues, many of which we found in the IRB that I chaired, came 
together and really have a system that got--that launched that 
had 300-and-some single-point failures, any one of which would 
have been mission-catastrophic. And for all of them to have 
worked is a credit to NASA and to the engineering capability of 
a project.
    So I'm bouncing around. You're right. I might say, yes, we 
are learning from it, but I do want to point out that these 
missions are never going to be easy and free of some of the 
challenges that exist. We should just get as many of them out 
of the way as we can in the process.
    Chairman Lucas. And I will remember, Mr. Young, that point 
in one of the hearings, the discussion that the complexity of 
the instrument, the complications of the launch, and the fact 
that we would put it out where we could never go----
    Mr. Young. Yes.
    Chairman Babin [continuing]. Put a pair of sunglasses on 
it, perhaps, the way we'd done Hubble, was very unnerving.
    Mr. Scott, your testimony highlights that an issue for many 
NASA missions is the culture of optimism that results in 
unrealistic cost and schedule assumptions. Our Committee 
encourages NASA to pursue bold missions, but how can we 
encourage NASA to establish more realistic cost and schedule 
projections for the agency's science missions?
    Mr. Scott. Thank you, Chairman Lucas. A can-do spirit is 
helpful and necessary for the things NASA does. That's without 
question. What we're asking the agency do--to do, though, is 
continuing to make critical assessments, particularly of these 
large flagship missions, in terms of costs, schedule, and 
requirements. And that means asking the hard questions about 
these missions even if the answers aren't favorable to your 
project. It's important to balance the sense of optimism and 
can-do spirit with realism, particularly as it relates to the 
lack of maturity in some of these technologies, the 
scientific--balancing that with the scientific value of these 
missions, but really being able to more fully understand the 
challenges ahead and try to better balance these cost and 
schedule issues.
    The other issue is the decadal. I'm sort of somewhat 
sympathetic to NASA. The decadal survey puts out estimates on 
these projects, but those are early estimates. Those are 
immature estimates. And yet those become the yardstick by which 
eventually we start to judge NASA. So I think it's also making 
sure we better understand what those decadal estimates mean and 
then holding the agency more accountable as it fully matures 
and develops these additional estimates.
    Chairman Lucas. Dr. Lunine and Mr. Young, this Committee is 
working on a NASA authorization bill, and our bill sets NASA 
policy but does not provide funding for the agency. Recognizing 
the fiscal environment in which we are operating, how do we set 
policy for NASA's Science Mission Directorate without creating 
unrealistic expectations for the agency, which will be 
difficult to fund? How do we temper our optimism so they can be 
practical?
    Dr. Lunine. Well, I'm a scientist and not a policy person, 
Mr. Chairman.
    Chairman Lucas. You're a lucky person.
    Dr. Lunine. Yes, thank you. I know that. I recognize that 
every day. You know, I would just say that--and this isn't 
really answering your question, but I feel that the Nation's 
portfolio of space science projects represents something that, 
you know, looking back to this time in the future will be seen 
as one of the remarkable accomplishments of this Nation in 
terms of what we've done in exploring the universe and 
exploring our own Earth, the planets, the Sun. And, you know, 
being mindful of that, those decisions are very difficult to 
make. And I--you know, I recognize that, and I hope that those 
can be made with as much knowledge and perspective as possible.
    Mr. Young. If I could add to that, I think one of the 
things that has to be recognized with the task that you have is 
that there's a collection of activities that NASA does in the 
science arena that are probably better understood than 
something like James Webb Space Telescope is. So I think it's 
important to have a foundation of programs that advance the 
scientific understanding but that are not challenging the 
limits of possibility.
    But on the other hand, I think if we look back a decade or 
two decades from now and we have not been bold in including 
within the baseline of programs I'm talking about, programs 
like James Webb, like Mars Sample Return, I think we will 
collectively be disappointed that we did not pursue the 
opportunities that were there. And I think, again, what I was 
saying is pursuing those opportunities is really going to--is 
what's going to make the road difficult.
    I recall, going back to James Webb if I could spend just a 
minute--and I spent a lot of time up here interacting with--
when it was kind of also in the balance. But fundamentally, 
the--a question I got asked regularly was, was James Webb a 
step too far? And after I thought about it, bear with me as I 
answer it, I think the answer is yes. But if we had not taken a 
step too far, we would not have the incredible results that we 
have today.
    Now, you can't do that with everything, but there are 
special things like Hubble, like James Webb. And I happen to 
agree with Jonathan--and like Mars Sample Return, that taking a 
step a little bit too far is in the best interest of justifying 
the potential results we come back because it's the flagship 
missions that are going to kind of provide the James Webb kind 
of results. And I don't want to minimize the other, but 
everything can't be done that way. But a program that's absence 
of those kinds of programs would not be a program that we would 
be proud of.
    Chairman Lucas. Well put, Mr. Young, and thank you, Mr. 
Chairman, for indulging me. I yield back.
    Chairman Babin. Yes, sir, good questions. Thank you, Mr. 
Chairman.
    I'd like to call on Mr. McCormick from Georgia for 5 
minutes.
    Mr. McCormick. Thank you, Dr. Chair. I appreciate you and 
appreciate the witnesses being here, exciting topic. I will say 
as a naval aviator, ER doc, and soon-to-be payload specialist, 
I'm very interested in this topic, especially with NASA and its 
future activities. I'm worried about some of the things that we 
need to do to sustain a budget for NASA as we go forward and to 
be applicable but also accountable simultaneously.
    I would be remiss if I did not mention that the Science 
Mission Directorate seems to be plagued by the same issues as 
many of NASA's other departments, which constant deadline 
extensions, flawed cost estimating processes, and poor 
financial management at times. I hope that today's conversation 
can lead us to identify key issues and find ways to mitigate 
these resource constraints.
    I'm excited about NASA's successful test of the Double 
Asteroid Redirection Test, which is DART for most of us others. 
That program demonstrates the method for deconflicting an 
asteroid through kinetic impact and the implication it could 
have as a key to our goal for planetary defense, which I think 
is kind of cool. We've seen movies on this. I think Bruce 
Willis had a great depiction of--or maybe it was a documentary, 
I'm not sure--of how we mitigate that risk in the future 
because it is a real concern. I mean, we don't know when it's 
going to be, but we might as well have that capability in the 
future.
    Dr. Fox, now that we have successfully demonstrated the 
DART program, what's next for this program, and will we create 
multiple DARTs on standby for possible Near-Earth Objects?
    Dr. Fox. What a fabulous question. So the next thing in the 
planetary defense is the NEO Surveyor, which of course will be 
critical in characterizing and cataloguing anything that could 
need us to have sort of DART part 2 if you like. We don't have 
plans at the moment to have DART in--sort of little DARTs in 
storage. We don't have the resources in the planetary defense. 
We are, however, sort of, I think probably recycling maybe is 
the good way, sustaining, but we are reusing the OSIRIS-REx 
spacecraft. So after that gave us those precious samples from 
Bennu, it dropped the capsule and then did a nice maneuver. And 
eventually, we'll actually rendezvous with Apophis, which is a 
small asteroid that will come fairly close to the planet, not 
too close, but fairly close. And so we're using that to go and 
study close up another asteroid.
    Of course, we have our Lucy mission doing flybys of all the 
Trojan asteroids. We have Psyche on the way to a heavy metal 
asteroid, giving us all different views. And I just want to 
paraphrase something that Deputy Melroy said the other day, 
which was, you know, when she was studying--in her planetary 
days, she was studying asteroids. We had no idea what they 
looked like, you know, and now we've had these incredible 
close-up views. So we're doing such a great job, I think, of 
categorizing, understanding, and cataloging asteroids that 
could become problematic, so a very, very vibrant field for us, 
having survived asteroid autumn last year.
    Mr. McCormick. It sounds like you've done your homework, 
and it sounds like you have a lot of organization. It sounds 
suspiciously like a heavy metal band.
    But with that said, how much do we spend in time 
coordinating with other nations in these efforts, in sharing 
information and our like mindedness to survive something like 
that?
    Dr. Fox. Yes, I'm going to actually take that one for the 
record because I want to get you an accurate response with the 
actual organizations because I don't remember them now. But we 
work closely with worldwide--I mean, there are these sort of 
asteroid watch networks. And again, we will get you all that 
information.
    Mr. McCormick. OK. Yes. More to the point, I think we're 
all watching space. The question is, how much are we 
coordinating our efforts to defend against something that could 
be catastrophic? And then how do we protect our own 
technologies while at the same time being able to share the 
information we need in order to protect ourselves? That's the 
next step, I think, in the evolution of what we're trying to 
achieve here with DART or whatever----
    Dr. Fox. Right.
    Mr. McCormick [continuing]. The next program is going to 
be. That's just something I wanted to point out.
    Dr. Fox. Yes.
    Mr. McCormick. Mr. Scott, I'm almost out of time. I got 
about 1 minute. What is the most concerning issue that you have 
written a report that has not been addressed by NASA?
    Mr. Scott. Thank you for that question. I think it's not 
one issue. Annually, we issue top management challenges for the 
agency, which really points to the longstanding challenges, 
whether it's getting humans back to the Moon, addressing the 
cybersecurity issues. So from what--while NASA is making 
progress addressing each of those key challenges, I would point 
you to our top management challenges report, which really 
summarizes at a high level, we believe, the top issues and 
challenges NASA is facing across its programs and missions.
    Mr. McCormick. No. 1, what is it?
    Mr. Scott. They're all my favorite. I think there's like 
seven or eight of them, so I don't have a No. 1.
    Mr. McCormick. You're treating them like kids, huh? You 
don't want to have a favorite. I get it. OK. Well, I'd say in 
order for us to be accountable to people, just make sure that 
we're spending wisely. We budget--and that budget process has 
to be streamlined a little bit better. Thank you, Mr. Chair.
    Chairman Babin. Absolutely. Thank you. And I think 
everybody's asked questions, and so we're going to go back 
through with a second series if that's OK with everyone. And 
I'm going to call on the Ranking Member, Mr. Sorensen, first.
    Mr. Sorensen. Thank you, Mr. Chairman. And thank you, 
again, to our witnesses.
    You know, as Congress is tasked here in the wee hours of 
the morning of a spending package that we will be voting on 
very--hopefully, very, very shortly, all eyes are on spending. 
And so I do want to go back to something that--Mr. Young, that 
you said in your testimony. NASA should look at the most 
probable cost instead of the lowest credible cost. And so I do 
want to open this up to a more broader discussion because in 
2020, NASA's preliminary estimate, it would cost $2-3 billion 
to bring the samples being collected by the Perseverance rover 
on Mars back to Earth, $2-3 billion was the estimate.
    Last summer, just 3 years later, the Independent Review 
Board said that a more realistic estimate is $8-11 billion. And 
that's still preliminary. How can we, as Members of the 
Science, Space, and Technology Committee or, more broadly, 
Members of Congress, continue to justify that this is worth it 
in the long run? I think, as the Chairman and I are scientists 
at heart, we understand the value of being bold, Mr. Young, as 
you had said? How do we continue to do that if the cost 
overruns keep going up?
    Mr. Young. I notice there are no other volunteers. I'm 
trying to figure out how to do this within reasonable time. 
When projects are being put together and being--going through 
various approval processes within NASA, within the Congress, 
within the OMB (Office of Management and Budget), the thing 
that is--whether we like it or not, the thing that is 
encouraged is lowest credible cost. As Mr. Scott said, in that 
era, everybody is an optimist. And the difference between 
lowest credit--there are a lot of data that would support this 
between a lowest credible cost on a statistical basis I would 
say is like a 20/80. A most probable cost, there's like an 80/
20. Those numbers are at least a factor of two different.
    So what I'm really getting around to is that there's got to 
be some offsetting rule that everybody can't be in the cap--
camp of lowest credible cost because we're going to end up with 
ridiculous numbers as it turned out like $3 billion.
    Now, in a corporation where you're kind of betting a 
corporation, what do you do, OK? If I go back to my previous 
life, what we did was we had project people who developed 
costs, and they were optimists, and we knew they were 
optimists, and we wanted them to be optimists in--to lead the 
kind of projects we were talking about. But we did not want to 
bet the company on their numbers. So we had independent cost 
estimating capability, people whose job it was to develop the 
most probable estimate.
    So my argument would be in the front end of projects, we 
need to recognize that many of the numbers we're getting are 
lowest credible costs, and we need to have an independent 
capability to work on the objective of being, I'll call it, 
junkyard dogs, you know, people who are really looking at what 
this is really going to cost. And then the decisionmakers have 
got to recognize that these programs are difficult, and--you 
know, and it's going to take most probable cost. So then we can 
make judgments against the--more validity in the cost.
    So I believe we have capabilities to estimate cost. I think 
much of the Sample Return problem is not overruns in 
performance, it's overruns in estimating, and--that we had, you 
know. That's why I used the terms lowest credible versus most 
probable.
    Mr. Sorensen. And I look back at what the--what we were 
doing with respect to space and what it meant for us to get a 
computer in our hands that is this size and this weight. What 
is the value of the investment that we made back then? And we 
can't calculate what that is here today. And that's what I 
worry here in Congress as we're struggling to meet the needs of 
what it means to be bold in space. And so I hope that we are 
able to do the right thing and fund the right parts. Thank you, 
Mr. Chairman.
    Chairman Babin. Yes, sir. Thank you.
    I just had a couple of follow up questions. For Mr. Young, 
you chaired the Independent Review Board for NASA's Psyche 
mission. Similarly to the OIG's report, the Review Board report 
noted that delays attributed to COVID-19 may actually be rooted 
in deeper program issues. I'd like to provide you with an 
opportunity to discuss the characteristics of large missions 
that contribute to delays and cost increases if you don't mind.
    Mr. Young. Psyche is an interesting example, and it was 
done during the COVID time period. So there's no question but 
what COVID had an adverse impact on Psyche and projects because 
project management is a team sport. And what I mean by that is 
people really need to be face-to-face and--to work it out. But 
it would be wrong to blame even a majority of Psyche's problems 
on COVID. It was certainly a factor.
    But Psyche clearly had some--started as some software 
development problems in the guidance and control of software 
that were poorly communicated throughout the organization, were 
not recognized until it was too late to have corrective action 
that would have allowed the project to go on schedule.
    The other thing I would say with that is to JPL's credit, 
when we interacted with them from the IRB standpoint, we really 
push hard on this issue of hybrid work vis-a-vis in-person 
work. And they put together a concept that recognized 
employees' maybe cultural differences but necessary to make the 
project work.
    I guess the other thing I would say was that the IRB really 
stayed with JPL hand-in-hand all the way through the process, 
and they developed a path forward, that when we first reviewed 
it, we said you need to go back and there's some other things 
you need to do. And they did. So, I mean, JPL and NASA's 
response to that, they accepted every recommendation we had. 
They responded to them. And Nicky probably remembers, but she 
came out to get a preliminary assessment of what we were doing, 
and my comment was at that time, which is true, that we had 
high expectations for what they were going to do, and they 
exceeded them. And so I think that really is--in my view, that 
is a textbook way to when you have a problem like that, you 
know, that you go about solving it. And what NASA and JPL did 
in responding to our recommendations was--we applauded quite 
significantly.
    And it's always rewarding--back to James Webb where I 
chaired the IRB there--and I don't want to make this sound like 
taking credit, but it's always pretty nice, and you can then 
sit back and watch like Psyche. It then launched on the revised 
schedule, and it's on the way to the asteroid Psyche and is 
performing extraordinarily well.
    Chairman Babin. OK. Thank you. And then also to follow up, 
Science Mission Directorate periodically conducts reviews of 
its operating missions known as senior reviews. The reviews 
provide a valuable opportunity for NASA to leverage its 
investments by extending the operations of spacecraft that 
continue to provide useful data beyond their planned lifetime. 
And while a useful tool, I'm interested in ensuring that NASA 
allocates its funding in the most efficient manner possible. In 
particular, recent senior reviews across SMD's divisions have 
recommended extending the majority of programs being 
considered. Does the senior review process assess how continued 
operations of a mission would impact NASA's budget? And how 
does NASA weigh whether extension of an existing mission is 
worth potentially diverting funds from a future mission? Mr. 
Young?
    Mr. Young. Yes, I'm not the person really to----
    Chairman Babin. OK.
    Mr. Young [continuing]. Comment on the--on that process.
    Chairman Babin. Then I bet it's Dr. Fox.
    Dr. Fox. Yes, happy to talk about that.
    Chairman Babin. OK.
    Dr. Fox. So--and we really value the senior review process 
because if we do have to make tough decisions, it does give us 
that ranking. Of course, nobody ever wants their mission turned 
off, and why would you? I wouldn't want mine turned off. So--
but it is challenging because we--as--when we talk about the 
balanced portfolio across the Science Mission Directorate, we 
really do mean in terms of our legacy missions with the new, 
exciting missions.
    I will--I do want to sort of highlight how the Earth 
Science Division has recently used their senior review. You 
know, they got a recommendation to maintain all of their 
operating missions. They did not have the resources to do it, 
so what they actually did was give a very challenging budget 
scenario to each of those operating missions, and, boy, did 
they deliver. So they are cutting those--the actual budget to--
you know, finding creative, efficient ways to keep operating 
the missions. Maybe you can't do it in the way you've always 
done it before in prime mission, but there are efficiencies you 
can make to extend the missions, and we've seen that across the 
portfolio where, you know--so we find that the senior review 
process is very, very valuable. We do like it when they give us 
the ranking of the missions because it does make it easier when 
we have to make those hard decisions.
    Chairman Babin. OK. Thank you very much. And I'm out of 
time.
    I'd like to call on gentleman from California once again.
    Mr. Garcia. Thank you, Mr. Chairman.
    Chairman Babin. Yes, sir.
    Mr. Garcia. I want to follow up on the Mars Sample Return 
discussion that we were having. I'm a dog with a bone on this 
one because it's so important to us, and the damage here is 
tremendous, not to just my district, but to all of southern 
California, to all of, frankly, the NASA workforce industrial 
base and the implications of this bad behavior are far-
reaching.
    This was premature, pre-decisional based on pre-decisional 
conversations in Congress that were happening real-time between 
both the House and the Senate, very shortsighted, and has 
caused irreparable damage. I describe this as nothing short of 
a bag job against the good folks at JPL, people who are now 
unemployed, looking for other industries, looking for other 
jobs, almost 600 folks as a result of this bad decision. It's a 
slap in the face to Congress, both the authorizers and the 
appropriators.
    So you mentioned, Dr. Fox, the Antideficiency Act. The 
Antideficiency Act is meant to be a way to ensure that agencies 
aren't spending more than what they are appropriated to. Your 
Fiscal Year 2023 appropriations number was $818 million, 
$818.8--I believe, to be exact--million. OK? You made the 
decision for the layoffs on February 6, which is about roughly 
35 percent through the fiscal year, so 35 percent of $818 
million is about $286 million. So you were either--this 
program--and I don't want to say you. This program was either 
burning hot at a rate of 3X and you were therefore looking at 
an Antideficiency Act to breach, or the remaining money, the 
delta between $818 million, which is what you were last 
appropriated, and $286 million, which would have been your sort 
of SPI (schedule performance index) for a 35 percent profile 
through the Fiscal Year 2023, was reprogrammed to another 
program.
    So this argument that you made these decisions based on an 
Antideficiency Act actually is technically and legally not true 
unless you were burning at a 3X rate or you did reprogram money 
to another program from MSR to something else that we weren't 
notified for. And I would actually submit that the appearance 
of what has been done here is not an Antideficiency Act 
violation or an attempt to prevent an Antideficiency Act 
violation, but it looks more like an Impoundment Act violation 
to me, which is where you don't execute the money that has been 
allocated to you with a specific purpose through congressional 
appropriations process.
    So I don't--out of deference to you, I don't want you to 
answer that question here, right now, but I would like a deeper 
dive into why you are asserting and your staff is asserting 
that the rationale for these layoffs was an Antideficiency Act 
because it, frankly, technically, legally, numerically, 
programmatically, it cannot hold water unless you were burning 
at 3X, which I don't think you were. I understand you're in the 
midst of an IRB. There was confusion about the technical 
solutions moving forward. I understand there was confusion 
about the timelines and schedules that would be derived from 
those technical solutions. And I also understand Congress was 
doing you a disservice with a CR But to baseline against a $300 
million number that came out of the Senate markups is not what 
you anchor to when you start talking about Antideficiency Act 
conversations. OK? You anchor to your previously appropriated 
number, which was $818 million.
    So happy to let you comment on that right now if you want 
to. If you would prefer to answer for the record later with the 
actual numbers and your SPI and your actual burn rates and show 
us where money was being reallocated before February 6 to 
substantiate the layoffs, you can also do that, but I'll defer 
to you.
    I want to make sure--a lot of these jobs are already lost. 
A lot of these people are already gone, so I don't know how we 
do MSR correctly without that workforce. We're already 
challenged, and there's already--you know, there's an 
unprecedented level of competition right now between primes to 
go hire these people when they're getting scooped up. But I'll 
defer to you, Ms.--Dr. Fox, if you want to respond.
    Dr. Fox. I'm happy to take it for the record so we can get 
you all--I mean, you are asking some--for some very deep 
numbers that, of course, I don't have at the tip of my tongue, 
so we're happy to take it for the record. Obviously, again, we 
have--you know, we do not direct JPL on their workforce. We did 
provide them financial guidance that was based on what we 
thought was going to be available and having been given the 
information--or, you know, with the Fiscal Responsibility Act 
coming out at the--no higher than the 2023 and a cut below 
that.
    I will just note that the cut to Planetary is nearly half a 
billion dollars against the 2023 enacted, and it is $666 
million against the President's budget request for 2024, so it 
is a very big cut to Planetary.
    Mr. Garcia. Yes, but from an Antideficiency Act--and I'm 
out of time--that is not what you should have been anchoring 
to. We were allowed and we were able to continue to fight for 
the higher dollar levels. And so we can continue this 
conversation, but I just--I'm scared. I'm scared. I'm worried 
about the workforce. And it's not my district, it's southern 
California, and we'll be looking for responses to the letters 
from the delegates from the area.
    Thank you. I yield back.
    Chairman Babin. Thank you, Mr. Garcia, appreciate it.
    Well, this concludes our hearing today, but I want to thank 
each one of you witnesses for being here and your valuable 
testimony for us to be able to have proper oversight and know 
what's going on with our programs.
    The record will remain open for 10 days for additional 
comments and also for written questions from Members.
    This hearing is now adjourned.
    [Whereupon, at 11:40 a.m., the Subcommittee was adjourned.]
