Statement of

Sean O’Keefe

Administrator

National Aeronautics and Space Administration

before the 

Committee on Science

House of Representatives 

Mr. Chairman and Members of the Committee, I appreciate the opportunity to appear before the 

Committee today to discuss the President’s FY 2004 budget proposal of $15.47 billion for 

NASA. The President’s request demonstrates the Administration’s continued confidence in 

NASA’s ability to advance the Nation’s science and technology agenda.

We come together to discuss NASA’s space research and exploration agenda, and our efforts to 

advance aviation safety and efficiency in this Centennial of Flight year, still mourning the tragic 

loss of the courageous crew of the Space Shuttle Columbia. Before I discuss the details of 

the budget, I would like to provide the Committee an update about the on-going investigation.

Today, 26 days after the tragic loss of Columbia, our work continues to honor the solemn pledge 

we’ve made to the families of the astronauts and to the American people that we will determine 

what caused the loss of Columbia and its crew, correct what problems we find, and safely continue 

with the important work in space that motivated the Columbia astronauts and inspires millions 

throughout the world.

Since I last appeared at the joint hearing between this Committee and the Senate Commerce 

Committee on February 12, the independent Columbia Accident Investigation Board under Admiral 

Gehman has made significant progress in organizing its work to determine the cause of the 

accident. NASA has kept its pledge to fully cooperate with the work of the Board, and has taken 

the necessary steps to ensure the Board’s complete independence.

Recovery operations, which began as soon as it became clear that Columbia was lost, continue on 

the ground in places along the Shuttle’s reentry path, stretching from San 

Francisco, California to Lafayette, Louisiana, where we hope to recover more vital debris from the 

accident. We continue to send everything we find to the Kennedy Space Center in Florida for 

assembly and analysis as part of the Columbia Accident Investigation Board’s comprehensive 

accident investigation.

The careful search for debris will continue in the weeks ahead, with our best opportunity to find 

remaining debris occurring in the next few weeks before the spring growing season begins. As I 

told the joint committee hearing on February 12, NASA is deeply grateful for the support we have 

received during recovery operations from more than 2000 men and women from the Department of 

Homeland Security, Federal Emergency Management Agency, Environmental Protection Agency, 
Federal Bureau of Investigation, Department of Defense, Department of Transportation, U.S. Forest 

Service, U.S. Park Service, Texas and Louisiana National Guard, and state and local authorities 

who have helped us locate, document, and collect debris. 

Implications of Suspension of Shuttle Flights

Mr. Chairman, you specifically requested that I address the implications of suspension of Shuttle 

flight for other programs, including the International Space Station (ISS), Hubble Space Telescope, 

and plans for the Orbital Space Plane Program. You also asked that I address near- and long-term 

contingency planning for the ISS. I will provide a brief summary, and am prepared to discuss the 

status with you in detail today, and in the weeks and months ahead.

With respect to the ISS, the Expedition 6 crew--Commander Ken Bowersox, Science Officer 

Donald Pettit and Cosmonaut Flight Engineer Nikolai Budarin--continue to perform science while 

performing routine ISS maintenance on orbit. There are no threats to the ISS or its crew in the near 

term, and we are working options to be able to sustain both over the long term. All 

remaining U.S. manufactured ISS hardware for the Core Complete configuration has been delivered 

to KSC and element ground processing is on schedule. Delivery of Node 2, built for NASA by the 

European Space Agency, is on schedule for April 2003. Ground processing will continue until 

ready for Shuttle integration. Only one ISS mission, STS-118, in the critical path to U.S. Core 

Complete was manifested on Columbia. The primary mission objective of STS-118 is the transfer 

and installation of the S5 Integrated Truss assembly to the S4 Truss. While the manifest for the 

remaining three Orbiters will need to be adjusted to accommodate this flight, all other previously 

scheduled ISS assembly missions will be flown in their original order. A 

revised U.S. Core Complete assembly schedule will be confirmed when the Shuttle is ready to 

return to flight status.

With respect to the Hubble Space Telescope (HST), NASA can continue to service it, and any 

Orbiter is capable of supporting HST servicing missions. Furthermore, the HST is performing well, 

and is a robust observatory in no immediate need of servicing. Should a delay in the planned 

servicing mission (November 2004) occur that impacts the Telescope’s ability to perform its 

science mission, HST can be placed in safe mode until a servicing mission can be arranged.

With respect to the Orbital Space Plane Program (OSPP), I am pleased to report that NASA 

recently released the OSPP Level One Requirements. The OSPP Mission Needs Statement directs 

that the OSPP vehicle(s) and associated systems shall support U.S. ISS requirements for crew 

rescue, crew transport, and some cargo. The requirements mandate that the system, which may 

include multiple vehicles, shall provide rescue capability for no fewer than four ISS crew as soon as 

practical but no later than 2010. The requirements also state that the system shall provide 

transportation capability for no fewer than four crew to and from the ISS as soon as practical but no 

later than 2012. These requirements, drafted prior to the loss of Columbia, already reflect schedule 

urgency. Immediately following the Columbia tragedy, an inter-Center team was convened to 

consider options to responsibly accelerate the program while still addressing NASA's requirements.

In the absence of Space Shuttle support, NASA is addressing contingency requirements for the ISS 

for the near- and long-term. As I said earlier, there is no immediate danger to the Expedition 6 

crew. In order to keep the crew safe, however, we must ensure that they have sufficient 

consumables, that the ISS can support the crew, and that there is a method for crew return 

available. Working closely with our international partners, we have confirmed that there is 

sufficient propellant on-board the ISS to maintain nominal operations through the end of this 
year. With the docking of the Progress re-supply spacecraft on February 4 (ISS Flight 10P), the 

crew has sufficient supplies to remain on the ISS through June without additional re-supply. As we 

move beyond June, however, potable water availability becomes the constraining commodity. We 

are currently working closely with our Russian partner, Rosaviakosmos, to explore how best to 

address this issue on future near-term ISS re-supply missions. A Soyuz spacecraft (ISS Flight 5S) 

is docked to the ISS and serves as a rescue vehicle for crew return in the event of a 

contingency. These Soyuz spacecraft have an on-orbit lifetime limitation of approximately 200-210 

days, and must be replaced periodically. The Soyuz 5S vehicle will reach its lifetime limit in late 

April/early May, and will need to be returned.

We are currently evaluating strategies with our International Partners to keep the ISS crewed and 

supplied with sufficient consumables, and to replace the Expedition 6 Crew. The ISS Partnership is 

committed to maintaining crew on-orbit. To address the near-term anticipated shortfall in potable 

water, one of the strategies that NASA and its partners are considering is bringing up a new crew of 

two (one U.S. and one Russian) on the next Soyuz spacecraft (ISS Flight 6S), scheduled for launch 

in late April. to replace the Expedition 6 Crew of three. We are also working closely with 

Rosaviakosmos to evaluate the flexibility and constraints of the Progress flight schedule to support 

the crew.

In the unlikely event that de-crewing is required, the ISS can be configured and de-crewed using 

established contingency procedures. The ISS can remain without a crew for an extended period of 

time while maintaining altitude with Progress and onboard re-boost capability, without crew 

interaction. NASA will continue to meet its commitments to our ISS International Partners. Once 

we understand what caused the Columbia accident and can return to flight, we will resume 

assembly of the ISS.

The ISS, now in its third year of human occupancy, represents an important milestone in 

history. Due to this capability, humans are now able to permanently occupy the realm outside of 

Earth and are actively conducting ambitious research spanning such scientific disciplines as human 

physiology, genetics, materials science, Earth observation, physics, and biotechnology.

FY 2004 Budget Request

On that sunny Saturday morning, February 1st, as I awaited the landing of the Columbia, I was 

contemplating my return to Washington, D.C., to prepare for the release of NASA’s FY 2004 

budget. We had worked aggressively over the past year to develop a new Strategic Plan and fashion 

a budget to make it a reality. I was excited about announcing these plans with the release of the 

President’s FY 2004 Budget in two days. I had no idea how that tragic morning would change my 

focus over these ensuing weeks. During the days that followed, I was asked by some whether 

the Columbia accident would force us to toss aside our budget and long-range plans. Mr. 

Chairman, I will tell you as I told them, I think not. A test of any long-term plan is whether it can 

accept the inevitable setbacks and still achieve its goals. That is my hope for our plan.

Mr. Chairman, in light of the recent tragic loss of Columbia, we must recognize that all exploration 

entails risks. In this, the Centennial Year of Flight, I am reminded of an accident that occurred just 

across the river at Ft. Myer in 1908 onboard the Wright flyer. The Wright brothers were 

demonstrating their flying machine to the U.S. Army, and a young lieutenant was riding as an 

observer. The flyer crashed, and Lt. Thomas Selfridge died of head injuries, thus becoming the first 

fatality of powered flight. From that accident in 1908 came the use of the crash helmet. So too 

from Columbia we will learn and make human space flight safer.
Although the budget proposal was prepared prior to the loss of Columbia and its crew, I am 

convinced that NASA’s FY 2004 budget proposal is responsible, credible, and compelling. It 

is responsible by making sure that our highest priorities are funded; it is credible by ensuring that 

adequate budget is built into the most technically challenging programs, and that we will fully 

account for the costs of all our programs; and, it is compelling by allowing NASA to pursue 

exciting new initiatives that are aligned with our strategic objectives. As I mentioned previously, 

the President’s FY 2004 budget request for NASA is $15.47 billion. While I will not rule out 

potential adjustments to this proposal that may be appropriate upon completion of the independent 

Gehman Board investigation, I look forward to discussing the FY 2004 budget request and how it 

advances our mission goals of understanding and protecting the home planet, exploring the 

Universe and searching for life, and inspiring the next generation of explorers, and, in so doing, 

honoring the legacy of the Columbia astronauts.

Establishing Our Blueprint

Today’s discussion is about more than changes in the budget – which is usually just a discussion 

over how one might change a few percent of one’s budget from the year to year – but instead it is 

about a new strategic direction for NASA and how we are planning to shift our resources toward 

our longer-term goals. In April 2002, I gave a speech at the Syracuse University that espoused a 

new Vision and Mission for NASA. There are only 13 words in NASA’s Vision and 26 words in 

NASA’s Mission, but every word is the product of extensive senior leadership debate within 

NASA. And what you see in our new Strategic Plan is the product of those discussions, and the 

product that the entire NASA team is committed to delivering for the American people. Indeed, we 

did not need to release this Strategic Plan with our budget – after all, the law stipulates September 

2003 – but we felt that if we are serious about our Vision and Mission, we must have it during our 

budget deliberations and release it simultaneous with our budget.

NASA’s strategy for the future represents a new paradigm. In the past, we achieved the marvel of 

the moon landing, an incredible achievement that has shaped much of NASA today, driven by a 

great external event – the Cold War – that allowed our Nation’s treasury to be aggressively spent on 

such a goal. Today, and in the decades since Apollo, NASA has had no comparable great external 

imperative. This, however, does not mean that we cannot lift our eyes toward lofty goals and move 

up the ladder – using the stepping stones we have identified. We believe that we can make great 

strides in our exploration goals – not on some fixed timescale and fixed location – but throughout 

our solar system with ever more capable robotic spacecraft and humans to enable scientific 

discovery. Hence, we will not be driven by timeline, but by science, exploration, and 

discovery. We will pursue building blocks that provide the transformational technologies and 

capabilities that will open new pathways. We can do this within our means. And if someday there 

is an imperative or new discovery that pushes us further, we will be ready and well along the way.

To be successful, we will transform ourselves as follows:

• All investments will contribute to our goals and traceable to the Vision and Mission. Every 

NASA program and project must be relevant to one or more of the goals, and perform 

successfully against measures.

• Human space flight capabilities will be expanded to enable research and discovery. We 

will continue to expand human presence in space -- not as an end in itself, but as a means to 

further the goals of exploration, research, and discovery.
• Technology developments will be crosscutting. We will emphasize technologies with 

broad applications, such as propulsion, power, computation, communications, and 

information technologies.

• Education and inspiration will be an integral part of all our programs. We will track 

performance of our education programs like that of any other NASA activity.

• We will operate as One NASA in pursuit of our Vision and Mission. We will reinforce the 

shared commitment of all NASA employees to our common goals.

• As Only NASA Can: We will pursue activities unique to our Mission -- if NASA does not 

do them, they will not get done -- if others are doing them, we should question why NASA 

is involved.

Strengthening our Foundation

This building block and stepping stone approach already has one important brick in place: the FY 

2003 Omnibus Appropriations Act, signed by the President on February 20. The FY 2003 

appropriation contains many of the needed elements that will help NASA address important 

constraints in power, transportation, and human capabilities. The FY 2003 budget contains funding 

for NASA’s:

• Nuclear Systems Initiative to develop new power and propulsion technologies that will 

enable solar system exploration missions that are inconceivable with current conventional 

chemical propulsion systems. This initiative has been incorporated in Project 

Prometheus as part of our FY 2004 Budget request.

• International Space Station (ISS), including full funding to assure we can successfully 

reach the milestone of U.S. Core Complete—which will enable accommodation of 

International Partner elements—maintain progress on long-lead items for enhanced 

research, and continue to build out this research laboratory platform for overcoming human 

limitations in space. It also includes authority to proceed with establishment of a NonGovernmental Organization (NGO) for ISS research. This funding and authority builds on 

our major achievements over the past year. We have received endorsements by two 

independent cost teams that deemed the program’s cost estimates as “credible” and the ISS 

Management and Cost Evaluation (IMCE) independent task force, chaired by Tom Young,

that commended our progress against their recommended management reforms. We have 

revamped our science program towards the highest priority research as identified by the 

Research Maximization and Prioritization (ReMAP) independent task force. We have put 

in place a new management team to control program content, ensure science requirements 

are met, and refocus program from development to operations. Finally, we are 

implementing new financial management tools to better manage our resources.

• Integrated Space Transportation Plan (ISTP) that will address our Nation’s near and midterm requirements in human space flight by making investments to extend the Shuttle’s 

operational life for continued safe operations; developing a new Orbital Space Plane 

to provide a crew transfer capability as early as possible to assure access to and from the 

International Space Station; and, funding next-generation launch vehicle technology in such 

areas as propulsion, structures, and operations. Since providing our ISTP as part of the FY 

2003 budget amendment in November 2002, we have moved out aggressively on this 

roadmap. We are refining the Shuttle’s Service Life Extension Program to better identify 

priorities and long-term investments. We also have completed top-level requirements for 

the Orbital Space Plane and awarded contracts to address priority technologies and areas of 

risk. Finally, we are refining our investments in long-term launch technologies as part of 

our recently initiated space architecture activities. We believe the ISTP is a good plan, but 
we are committed to re-examining it if necessary in light of future investigation findings 

on Columbia.

We must ensure that we have a sound foundation—our people, processes, and tools—from which to 

build our programs. It is only from such a sound foundation that we can go forward to more 

ambitious plans. We have placed the highest priority on achieving the goals of the President’s 

Management Agenda, which contain five Government-wide initiatives that promise to significantly 

improve our management foundation:

• Human Capital: We have begun to implement our strategic human capital plan, including a 

tracking system to identify workforce deficiencies across the Agency. I will address this 

very important issue at the conclusion of my remarks.

• Competitive Sourcing: We have achieved the government-wide, 15 percent competitive 

sourcing goal, and are pursuing, wherever feasible, new opportunities for competition, 

including the renewal of contracts. 

• Financial Performance: We have addressed all issues contained in the disclaimer opinion 

on NASA’s 2001 audit and been given a clean opinion for 2002. 

• E-Government: We are addressing information technology security issues and reviewing 

and enhancing other IT capabilities. 

• Budget & Performance Integration: We are budgeting for the full cost of NASA’s 

programs and have integrated our budget and performance plan starting with FY 2004 

Budget.

Mr. Chairman, I would like to specifically highlight NASA’s newest Enterprise, Education. The 

Education Enterprise was established in 2002, to inspire more students to pursue the study of 

science, technology, engineering and mathematics, and ultimately to choose careers in those 

disciplines or other aeronautics and space-related fields. The new Enterprise will unify the 

educational programs in NASA’s other five enterprises and at NASA’s 10 field Centers under a 

One NASA Education vision. NASA’s Education vision will permeate and be embedded within all 

the Agency’s activities.

Linking Investments to Strategic Plan

Simultaneously with the submission of the President’s FY 2004 budget request, we submitted to the 

Congress the Agency’s new Strategic Plan, our Integrated Budget and Performance Document, and 

our Performance and Accountability Report. I believe the sweeping changes we are proposing in 

our FY 2004 Budget represent the most ambitious in our history and will enable us to vastly 

improve our ability to align our investments with our goals, assess progress, and make sound 

economic and technical decisions based on accurate and timely information. These improvements 

include:

• Budget Restructure – In response to our new Strategic Plan, we have restructured our 

budget. NASA’s new Strategic Plan recognizes that we are organized by those Missiondriven activities that deliver our end products—Space Science, Earth Science, Biological 

and Physical Research, Aeronautics, and Education—and by those activities—

International Space Station, Space Shuttle, Space Flight Support, and Crosscutting 

Technology— that enable our Mission-driven activities to succeed. To mirror the 

organization of activities in our Strategic Plan into mission-driven efforts and supporting 

capabilities, and to recognize the reality that there is no arbitrary separation between human 

and science activities, the FY 2004 budget replaces the previous structure with two new 
appropriation accounts: Science, Aeronautics and Exploration; and, Space Flight 

Capabilities. For FY 2004, the request includes $7.661 billion for Science, Aeronautics 

and Exploration and $7.782 billion for Space Flight Capabilities.

Furthermore, the budget is structured in 18 goal-oriented Themes, which aggregate 

programs to be managed as a business portfolio in pursuit of common goals and 

performance measures.

• Full Cost Accounting and Management – In a landmark event, we have allocated all our 

costs by program areas. Throughout our history, NASA has treated the cost of institutional 

activities (personnel, facilities, and support) separate from the programs they benefit. This 

has made economic trades difficult to analyze. In this budget, we have placed all costs 

against programs so that, for the first time, we can readily determine the true total costs of 

programs and allow managers to make more efficient and effective choices.

• Integrated Budget and Performance Document – We have revamped our Congressional 

justification with a new document that merges our restructured budget with our 

performance plan. The document highlights the 18 themes and associated performance 

measures. Moreover, it clearly identifies projects approved for full scale development, 

including promised cost, schedule, and technical parameters.

• Integrated Financial Management System – After a decade of trying, we are successfully 

bringing online a new integrated financial management system. For the first time in the 

agency’s history, we will have one financial system for all our Field Centers, a major step 

in our One NASA goal. The core financial module will replace the legacy systems at all our 

Centers by this summer. This new system implementation is critical for enabling 

successful management of the budget, cost, performance, and the accounting changes 

mentioned above. Moreover, this new system will significantly enhance our ability to 

maintain a clean financial audit opinion.

Pursuing Critical New Opportunities

At NASA, we are developing building blocks that open new pathways of exploration and 

discovery. Today, our telescopes peer billions of years into the past to witness the beauty and 

unlock the mysteries of the early universe. Our satellites view the entire planet from space, 

allowing us to study global change and its consequences for life on Earth. Our spacecraft travel 

throughout the solar system and into the uncharted territories beyond, exploring the processes that 

have led to the incredible diversity of the planets and the emergence of life. Our aeronautics 

research has given people the routine ability to travel safely and reliably all around the world. Our 

astronauts are living and working in space, and from them, we are learning how to expand our 

sphere of exploration far beyond the bounds of Earth.

But, our ability to fully achieve our Mission is constrained by the need for new technologies that 

can overcome our current limitations. We must provide ample power for our spacecraft as well as 

reliable and affordable transportation into space and throughout the solar system. We must deploy 

innovative sensors to probe Earth, other planets, and other solar systems. We must be able to 

communicate large volumes of data across vast distances, so that we can get the most from our 

robotic explorers. And we must learn to mitigate the physiological and psychological limitations of 

humans to withstand the harsh environment of space.
To address these and other challenges, we must build upon the strategic investments we are making 

in the FY 2003 Budget and pursue critical new opportunities. Consequently, our FY 2004 Budget 

request includes nine new initiatives:

• Project Prometheus will use breakthrough nuclear propulsion and power systems to fuel an 

ambitious mission to Jupiter’s icy moons, which astrobiologists believe could harbor 

organic material, and lay the groundwork for even more ambitious exploration missions in 

the coming decades. The FY 2004 budget request includes $93 million for this initiative, 

and $2.07 billion over five years.

• Human Research Initiative will conduct biomedical research and develop technologies to 

enable safe and efficient long-duration space missions, including potential future missions 

beyond low-Earth orbit. This initiative will provide knowledge and technology for efficient 

life support on the ISS, and has potential medical benefits for millions here on Earth. The 

FY 2004 budget request includes $39 million for this initiative, and $347 million over five 

years.

• Optical Communications Initiative will invest in revolutionary laser communications 

technologies that will allow planetary spacecraft to transmit large volumes of scientific 

information, and will be demonstrated on a Mars mission in 2009. The FY 2004 budget 

request includes $31 million for this initiative, and $233 million over five years.

• Beyond Einstein Initiative will launch two Einstein Observatories: LISA (Laser 

Interferometer Space Antenna), a deep-space-based gravity wave detector that will open 

our eyes to the as-yet-unseen cosmic gravitational radiations; and Constellation-X, a 

mission that will tell us what happens to matter at the edge of a black hole. In addition, the 

FY 2004 budget request provides funding to initiate Einstein Probes, three spacecraft that 

will answer: “What powered the Big Bang?” (the Inflation Probe); “How did black holes 

form and grow?” (the Black Hole Finder Probe); and, “What is the mysterious energy 

pulling the Universe apart?” (the Dark Energy Probe). The FY 2004 budget request 

includes $59 million for this initiative, and $765 million over five years.

• Climate Change Research Initiative is an interagency effort to accelerate research targeted 

at reducing key scientific uncertainties to help the Nation chart the best course forward on 

climate change issues. The FY 2004 budget request includes $26 million for this initiative, 

and $72 million over five years.

• Aviation Security Initiative will develop technologies to help reduce the vulnerability of 

aviation to terrorist and criminal attacks. The FY 2004 budget request includes $21 million 

for this initiative, and $225 million over five years.

• National Airspace System Transformation Augmentation will accelerate the development of 

technology to help address efficiency, capacity and security needs. The FY 2004 budget 

request includes $27 million for this initiative, and $100 million over five years.

• Quiet Aircraft Technology Acceleration will develop technology to help significantly 

reduce community noise impact and achieve significant savings in amelioration 

programs. The FY 2004 budget request includes $15 million for this initiative, and $100 

million over five years.

• Education Initiative includes funding for NASA’s Educator Astronaut 

Program, NASA Explorer Schools, NASA Explorer Institutes, and Scholarship for 

Service. The FY 2004 budget request includes $26 million for this initiative, and $130 

million over five years.

While there have been additional funding provided to NASA’s previous five-year budget runout to 

provide for these new initiatives, the balance of the funds for the initiatives has resulted from 

reprioritization of future funding to more appropriately pursue the Agency’s Vision/Mission and 
goals. These initiatives will plant the seeds to enable future achievements. From them, we will 

continually advance the boundaries of exploration and our knowledge of our home planet and our 

place in the universe. We seek answers along many paths, multiplying the possibilities for major 

discoveries. The capabilities we develop may eventually enable humans to construct and service 

science platforms at waypoints in space between Earth and the Sun. Someday, we may use those 

same waypoints to begin our own journeys into the solar system to search for evidence of life on 

Mars and beyond.

Mr. Chairman, as I indicated above, there is one additional point I wish to make. I would like to 

briefly discuss the state of our workforce, the lifeblood of this Agency. Last year, NASA submitted 

to the Congress a series of legislative proposals to help the Agency reconstitute and reconfigure our 

workforce. These provisions, for the most part, mirrored tools contained in the President’s 

proposed Managerial Flexibility Act, and three of them have since been enacted on a Governmentwide basis in the Homeland Security Act. We have worked extensively with this Committee to 

refine the remaining proposals, and we appreciate all the Committee’s efforts to date. NASA’s 

workforce is an aging workforce. At the time of Apollo 17, the average age of the young men and 

women in Mission Control was 26 years; today, we have three times as many personnel over 60 

years of age as under 30 years of age. Since 1999, there have been at least 18 studies and reports 

concerning the workforce challenges facing NASA. Within five years, nearly 25 percent of 

NASA’s current workforce will be eligible to retire. The potential loss of this intellectual capital is 

particularly significant for this cutting-edge Agency that has skills imbalances. I strongly solicit the 

support of the Committee to ensure expeditious enactment of this critical legislation.

Appended to my testimony, as Enclosure 1, is a chart displaying NASA’s FY 2004 five-year 

budget request. Also appended, as Enclosure 2, is a summary of the significant progress that NASA 

has made in the past year on a number of important research and exploration objectives, and a 

detailed summary of NASA’s FY 2004 budget request.

The Columbia accident has reminded me that we cannot stop dreaming. We cannot stop pursuing 

our ambitious goals. We cannot disappoint future generations when we stand at the threshold of 

great advances. Mr. Chairman, I believe that NASA’s FY 2004 budget request is well conceived 

and worthy of the favorable consideration by the Committee. I am prepared to respond to your 

questions.
