        This appropriation provides funding for Human Space Flight (HSF)
    activities, and for safety, mission assurance and engineering activities
    supporting the Agency. The HSF activities include development and
    operations of the Space Station and operation of the Space Shuttle. This
    includes high priority investments to improve the safety of the Space
    Shuttle, and required construction projects in direct support of Space
    Station and Space Shuttle programs. This appropriation also provides
    for: salaries and related expenses; design, repair, rehabilitation, and
    modification of facilities and construction of new facilities;
    maintenance, and operation of facilities; and other operations
    activities supporting human space flight programs; and space operations,
    safety, mission assurance and engineering activities that support the
    Agency.

        In 2001, the HSF account provided only for the direct funding of
    human space flight activities; space operations services had been funded
    within the Science, Aeronautics and Technology (SAT) account; and
    safety, mission assurance and engineering had been funded within the
    Mission Support account. Since 2002, other than direct costs (which
    includes Research and Program Management and non-programmatic
    Construction of Facilities) are allocated to either the HSF or the SAT
    account based on the number of full time equivalent people.

    Performance Objectives

        Space Station.--The International Space Station (ISS) is a complex
    of research laboratories in low Earth orbit in which American, Russian,
    Canadian, European, and Japanese astronauts are conducting unique
    scientific and technological investigations in a microgravity
    environment. The goal of the Station is to support scientific research
    and other activities requiring the unique attributes of humans in space
    and establish a permanent human presence in Earth orbit. The President's
    2003 Budget request provides funding for continued development of the
    vehicle and for operations in support of continued assembly, logistics
    resupply, crew exchange, research operations and other utilization. With
    nine assembly missions successfully completed, the budget includes
    funding to keep subsequent assembly missions on schedule through U.S.
    Core Complete (Flight 10A), currently planned for calendar year 2004, to
    support early research commensurate with the build-up of on-orbit
    utilization capabilities and resources.

        In early calendar year 2001, NASA launched the U.S. Laboratory and
    the first set of research equipment necessary for conducting experiments
    on the Space Station. Subsequent flights enabled the installation of the
    Canadian robotic arm, additional research equipment for the U.S.
    Laboratory, installation of the Russian docking compartment, and
    transport of the 3rd and 4th crew expeditions. By mid-calendar year
    2001, the U.S. Airlock had been installed, allowing spacewalks to be
    conducted without the Space Shuttle present, and marking completion of
    Phase 2 of the Space Station assembly. The first utilization flight in
    December 2001 greatly expanded the number of research payloads on-orbit,
    and raised the number of research investigations initiated to over 40.
    Crew training, payload processing, hardware element processing, and
    mission operations were supported without major ground anomalies, and
    all but two on-orbit subsystems performed above predicted levels,
    resulting in a lower than expected maintenance workload. This lower
    maintenance workload, coupled with the commitment of the expedition
    crews to dedicate time for conducting research experiments, resulted in
    research activities that exceeded expectations. NASA will seek to exceed
    expectations for research productivity by achieving astronaut time
    dedicated to research in excess of the planned 20 hours per week. During
    2002, three of the major truss elements constituting the power block
    will be deployed to orbit, Expeditions 5 and 6 will be deployed, and a
    second utilization flight will expand science capabilities even further.
    In calendar year 2003, activation of the thermal system will be
    completed, two of the three remaning solar array modules will be
    deployed, and both the S6 truss and Node 2, the final components of the
    U.S. Core Complete, should be delivered to NASA for final integration
    and pre-flight test and checkout to support planned launches in calendar
    year 2004.

        As required by both the NASA Authorization Act (PL 106-391) and the
    2002 VA/HUD Appropriations Act (P.L. 107-73), the ISS research budget is
    transferred to the Biological and Physical Research Enterprise in 2002.
    The remaining ISS budget supports completion of the U.S. Core Complete
    and allows the program to press ahead with the integration of the
    partners' research modules. A NASA cost estimate, and an independent
    cost estimate (ICE) of the cost to assemble and operate the U.S. Core
    Complete will be completed by September 2002. The 2002 appropriation
    directed a general reduction in the station budget of $75M, which
    eliminated reserves fenced for guaranteed carryover into 2003. The
    appropriation also earmarked $40M for X-38 efforts that was originally
    planned to cover X-38 plus continued work on Node 3 and the advanced
    environmental control system. NASA plans to fund the Node 3 and
    environmental control work into the 2nd quarter of 2002, when a decision
    will be made to continue those efforts or to cancel them.

        Consistent with the recommendations in the ISS Management and Cost
    Evaluation (IMCE) Task Force, and direction from the Administration,
    NASA will develop a Cost Analysis Requirements Document (CARD) to
    support cost estimates of the U.S. Core Complete baseline. NASA will
    also develop an integrated management action plan based on
    recommendations of the IMCE Task Force, and begin implementation of
    those actions. NASA will also report to the Administration and to
    Congress its plans for a non-governmental organization (NGO) for ISS
    research, and the results of discussions with the International Partners
    on ways to increase on-orbit resources for station research, in
    particular innovative methods for increasing crew availability. The ISS
    Program is pressing ahead with final flight hardware deliveries, and
    completion of the current prime contract in December 2003. Requirements
    for follow-on support are being reviewed and estimated, and a plan to
    competitively award contracts for the station's operations phase will be
    released this Spring.

        Payload and Expendable Launch Vehicle (ELV) Support.--The Payload
    Carriers and Support budget provides technical expertise, facilities,
    flight carrier hardware and capabilities necessary to provide end-to-end
    servicing of multiple payloads to be flown aboard the Space Shuttle.
    During 2001, six pallets were used in Space Shuttle missions. In 2002
    and 2003, over 20 major and secondary payloads will be supported,
    including major hardware for International Space Station assembly and
    operations.

        The ELV Mission Support budget provides funds for technical and
    management insight of commercial launch services, including advanced
    mission design/analysis and leading-edge integration services, which are
    provided for the full range of NASA missions under consideration for
    launch on ELVs. During 2001, eight ELV missions were launched.
    Integration and technical management of 11 launches, including one
    secondary, are planned in 2002. In 2003, support for ten launches,
    including one secondary, is planned.

        Investments and Support.--NASA's rocket propulsion test project will
    ensure that unique capabilities are properly managed and maintained in
    world-class condition. The project will significantly enhance NASA's
    ability to properly manage rocket testing activities and infrastructure
    across all four participating NASA centers. Engineering and technical
    base (ETB) activity will continue to: support the institutional
    capability in the operation of space flight laboratories, technical
    facilities, and testbeds; conduct independent safety, and reliability
    assessments; and stimulate science and technical competence in the
    United States. Funding for other direct costs associated with Human
    Space Flight, which were funded in the Mission Support account prior to
    2002, are also funded within investments and support. This includes
    research and program management costs and non-programmatic construction
    of facilities costs.

        Space Shuttle.--The Space Shuttle is a partially reusable space
    vehicle that provides several unique capabilities to the United States
    space program. These include retrieving pay-loads from orbit for reuse,
    servicing and repairing satellites in space, safely transporting humans
    to and from space, launching ISS components and providing an assembly
    platform in space, and operating and returning space laboratories.

        In 2001, the Space Shuttle launched seven flights, all of which were
    ISS assembly and servicing missions. Seven flights are planned during
    2002 including a dedicated microgravity research flight and another HST
    Servicing Mission (HST-3B) and five ISS assembly and servicing missions.
    In

    [[Page 1025]]

    2003, four flights are planned, all of which are ISS assembly and
    servicing missions. In support of the research objectives of the Space
    Station, the Space Shuttle will commit a minimum of five powered mid-
    deck lockers on each mission to deliver necessary research equipment and
    specimens.

        NASA will aggressively pursue Space Shuttle competitive sourcing as
    an important step in transitioning NASA from infrastructure ownership
    and operation to purchasing space transportation services where
    possible. NASA will seek industry comment on its plans early this year,
    leading to release of a solicitation for competitive sourcing. NASA will
    prepare a Cost Analysis Requirements Document (CARD) to support NASA and
    independent cost estimates of Space Shuttle operations and safety
    investments, similar to estimates being done for the Space Station.
    These estimates, to be completed by September, 2002, will provide an
    important baseline from which to assess competitive sourcing options.

        The President's 2003 Budget supports key Space Shuttle safety
    investments as part of NASA's Integrated Space Transportation Plan. NASA
    will seek to accelerate the implementation of safety investments, to
    begin achieving safety gains in Shuttle operations as quickly as
    possible. The President's 2003 Budget also supports investments in the
    Space Shuttle infrastructure, as necessary to address safety issues and
    critical repair and revitalization activities.

        Space Communications and Data Systems.--The program goal is to
    support NASA's Enterprises and external customers with Space
    Communications and Data System (SCDS) services that are responsive to
    customer needs. Additionally, the program performs infrastructure
    upgrades and replenishment efforts necessary to maintain the service
    capabilities that satisfy the approved mission model. The program
    conducts technology and standards infusion efforts to provide more
    efficient and effective services. The Space Communications Office at
    Headquarters manages and directs an integrated Agency-wide Space
    Communications and Data Systems program.

        Beginning in 2002, a decentralized management process has been
    implemented that involves transferring most management and budget
    responsibilities previously performed by the Space Operations Management
    Office to the appropriate Enterprises. Beginning in 2003, the Deep Space
    Network, Ground Network and Western Aeronautical Test Range will be
    managed by NASA's Enterprises. The Office of Space Flight will continue
    to perform overall program integration, including the management of
    Consolidated Space Operations Contract, which is now in its fourth year
    of providing data services to both NASA and non-NASA customers.

        The TDRS-8 spacecraft, which completed on-orbit checkout in
    September 2000, is working well and meets all user service
    telecommunications performance requirements except for a Multiple Access
    (MA) performance anomaly. Modifications to the TDRS-I and TDRS-J
    spacecraft flight hardware and test program as a result of the MA
    investigation have been implemented. TDRS-I launch is now planned for
    February 2002. The launch of TDRS-J is slated for October 2002.

        Safety, Mission Assurance and Engineering.--The Safety and Mission
    Assurance program invests in the safety and success of NASA missions by
    assuring that sound and robust policies, processes, and tools for
    safety, reliability, quality assurance, and engineering disciplines are
    in place and applied throughout NASA. The program also examines long-
    term technology requirements for NASA's strategic objectives. The
    Engineering program, managed by the Office of the Chief Engineer (OCE),
    oversees the conduct and improvement of NASA's engineering practice and
    independently evaluates ongoing programs, proposed concepts, and options
    for new programs. The OCE establishes policies, standards, guidance, and
    support for improving NASA engineering practices and technical
    capabilities, and manages the NASA Electronics Parts and Packaging
    Program, which supports evaluation and infusion of advanced electronic
    parts and packaging technology into NASA programs.

        This appropriation provides for the Science, Aeronautics and
    Technology (SAT) supporting the Agency. The SAT activities include space
    science, biological and physical research including research for the
    International Space Station, earth science, aerospace technology, and
    academic programs. This appropriation also provides for salaries and
    related expenses; design, repair, rehabilitation, and modification of
    facilities and construction of new facilities; maintenance and operation
    of facilities; and other operations activities supporting science,
    aeronautics, and technology programs.

        In 2001, the SAT account provided only for the direct funding of
    science, aeronautics and technology activities, and included funding for
    space operations services which are now funded within the Human Space
    Flight (HSF) account. Since 2002, other direct costs (which include
    Research and Program Management and non-programmatic Construction of
    Facilities) are allocated to either the HSF or the SAT account based on
    the number of full time equivalent personnel.

    Performance Objectives

        Space Science.--The Space Science program seeks to answer
    fundamental questions concerning: the galaxy and the universe; the
    connection between the Sun, Earth and heliosphere; the origin and
    evolution of planetary systems; and the origin and distribution of life
    in the universe. The Space Science program is comprised of many research
    and development activities, including flight missions, major space-based
    facilities, technology and mission development programs, and research
    and data analysis.

        In 2001, the Space Science program produced many notable scientific
    results: The Hubble Space Telescope discovered a supernova blast that
    occurred very early in the life of the Universe, bolstering the case for
    the existence of a mysterious form of ``dark energy'' pervading the
    Universe. The concept of dark energy, which pushes galaxies away from
    each other at an ever-increasing speed, was first proposed, then
    discarded, by Albert Einstein early in the last century. The Hubble
    discovery also reinforces the startling idea that the expansion of the
    universe only recently began speeding up.

        The Chandra X-ray Observatory enhanced our understanding of black
    holes on many fronts. Chandra took the deepest X-ray images ever and
    found the early Universe teeming with black holes, probed the
    theoretical edge of a black hole known as the event horizon, and
    captured the first X-ray flare ever seen from the supermassive black
    hole at the center of our own Milky Way galaxy.

        Detailed scientific analysis of high-resolution images obtained by
    the BOOMERANG (Balloon Observations of Millimetric Extragalactic
    Radiation and Geophysics) mission provided the most precise measurements
    to date of several of the key characteristics cosmologists use to
    describe the Universe. These images were the first to bring the cosmic
    microwave background (the radiation remaining from the ``big bang'' that
    created the Universe) into sharp focus.

        In addition to these discoveries that have enhanced our
    understanding of the origin, evolution, and structure of the Universe,
    many discoveries in 2001 related to the rapidly growing field of
    extrasolar planet (planets outside our Solar System) detection. NASA and
    National Science Foundation-funded astronomers discovered eight new
    extrasolar planets, bringing the total number of extrasolar planet
    detections to about eighty. Observations from the Submillimeter Wave As

    [[Page 1027]]

    tronomy Satellite (SWAS) provided the first evidence that extrasolar
    planetary systems contain water, a molecule that is an essential
    ingredient for known forms of life. Also in this field, astronomers
    using the Hubble Space Telescope have made the first detection and
    chemical analysis of the atmosphere of a planet outside our Solar
    System.

        Within our Solar System, NASA spacecraft made many stunning
    achievements in 2001. In a risky flyby, the Deep Space-1 spacecraft
    successfully navigated past comet Borrelly, giving researchers the best
    look ever inside a comet's glowing core of icy dust and gas. Deep Space-
    1 passed just 2,200 kilometers (1,400 miles) from the rocky, icy nucleus
    of the 10 kilometer-long (more than 6 mile-long) comet. The NEAR (Near
    Earth Asteroid Rendezvous) Shoemaker spacecraft achieved the first soft
    landing on an asteroid. The landing was the culmination of a year-long
    orbital mission at the asteroid Eros during which the mission returned
    enormous quantities of scientific data and images.

        A pair of spacecraft, the Mars Global Surveyor and the Hubble Space
    Telescope, provided astronomers with a ringside seat to the biggest
    global dust storm seen on Mars in several decades. The Martian dust
    storm, larger by far than any seen on Earth, raised a cloud of dust that
    engulfed the entire planet for several months. The sun-warmed dust
    raised Martian atmospheric temperatures by 80 degrees Fahrenheit while
    the shaded Martian surface chilled precipitously. Also in calendar year
    2001, the Mars Odyssey 2001 spacecraft successfully achieved orbit
    around Mars following a six-month, 286-million mile journey. Following
    aerobraking operations, this spacecraft will be placed in its science-
    mapping orbit in early calendar year 2002 and will characterize
    composition of the Martian surface at unprecedented levels of detail.

        In the field of Sun-Earth Connections, where we seek to develop a
    scientific understanding of the physical interactions in the Sun-Earth
    system, there were several important scientific accomplishments in
    calendar year 2001. The Solar and Heliospheric Observatory (SOHO)
    observed the largest sunspot in ten years, with a surface area
    equivalent to thirteen Earths. This area proved to be a prolific source
    of stormy solar activity, hurling clouds of electrified gas (known as
    Coronal Mass Ejections, or CMEs) towards Earth. Other studies conducted
    by the SOHO spacecraft have provided the first clear picture of what
    lies beneath sunspots, peering inside the Sun to see swirling flows of
    electrified gas that create the self-reinforcing cycle that holds a
    sunspot together.

        The calendar year was capped by the successful launch of the TIMED
    (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) mission
    on December 7, 2001. This is the first mission in the Solar Terrestrial
    Probes program. It will study a region of the Earth's atmosphere that
    has never been the subject of a comprehensive, long-term scientific
    investigation.

        The NASA budget request for 2003 features two very significant
    changes from the previous baseline program: a reformulated planetary
    program and the inclusion of a nuclear power and propulsion program. In
    the field of planetary exploration, the 2003 Budget takes a
    fundamentally different approach from previous years. Given cost growth
    and schedule delays, all funding for the Pluto-Kuiper Belt mission and
    the Europa Orbiter mission has been eliminated in 2003 and subsequent
    years. These missions will be replaced by a revamped planetary program
    that will incorporate the following principles: clear science priorities
    that support key goals in understanding the potential existence of life
    beyond Earth and the origins of life; open competition and rigorous
    reviews of cost, schedule, and risk to minimize future overruns and
    delays per the highly successful Discovery Program; and an architectural
    approach that balances science return in this decade with investments in
    high-leverage technologies that will enable faster and more frequent
    missions with greater science return in the next decade. It is
    envisioned that the new planetary program will be structured and managed
    along the lines of the highly successful Discovery program. A key
    element of this new program will be the development and incorporation of
    nuclear power and propulsion technologies. Building upon ongoing NASA
    investments in advanced electric propulsion and instrument and
    electronics miniaturization, investments in nuclear power and nuclear-
    electric propulsion technologies that will enable much faster and more
    frequent planetary investigations with greater science capabilities.
    These investments will allow NASA to undertake fundamentally new
    approaches to planetary exploration. In the next decade, nuclear-
    electric propulsion technology will enable affordable planetary missions
    that: can reach targets in half the time it would take using today's
    propulsion systems; are not limited by today's power and mass
    constraints; and can conduct long-term observations of multiple targets.

        Nuclear power technology will also be incorporated into the Mars
    Exploration Program, specifically in the Mars Smart Lander/Mobile
    Laboratory mission. This mission will now be launched in calendar year
    2009 to allow the incorporation of nuclear power, instead of calendar
    year 2007 as previously planned. By using nuclear power, the time during
    which the Mars Mobile Laboratory can conduct science operations will be
    extended from several months to several years. The nearer-term missions
    in the Mars Exploration Program remain essentially unchanged. In May and
    June of 2003, two highly capable surface rovers will be launched to
    Mars, with landings on the surface expected in April and May of 2004.
    The Mars Reconnaissance Orbiter (MRO) will be launched in calendar year
    2005; this powerful scientific orbiter will focus on analyzing the
    surface at unprecedented levels of detail to follow tantalizing hints of
    water detected in images from the Mars Global Surveyor spacecraft. MRO
    will measure thousands of Martian landscapes at 20- to 30-centimeter (8-
    to 12-inch) resolution. It will be followed by a competitively selected
    Mars Scout mission in calendar year 2007 and the Smart Lander/Mobile
    Laboratory in calendar year 2009. This robust program of orbiters,
    landers, and rovers is poised to unravel the secrets of the red planet's
    past environments, the history of its rocks, the many roles of water,
    and, possibly, evidence of past or present life.

        This Budget supports the completion of development of many
    significant missions, including Gravity Probe-B (GP-B), the Space
    Infrared Telescope Facility (SIRTF), and the Stratospheric Observatory
    For Infrared Astronomy (SOFIA). GP-B, which will verify a key aspect of
    Einstein's theory of general relativity, will be launched in October
    2002. SIRTF, the fourth and final of the Great Observatories, is
    scheduled for launch in 2003. SOFIA development activities will
    continue, with the aircraft door and the telescope to be installed and
    tested in 2003. Development activities supporting the Solar Terrestrial
    Relations Observatory (STEREO), the Gammaray Large Area Space Telescope
    (GLAST), the final Hubble Space Telescope servicing mission, as well as
    several key missions in the payloads program such as Solar-B and
    Herschel, will also continue in 2003.

        In the Explorer program, the Microwave Anisotropy Probe successfully
    launched on June 30, 2001, and development of Swift, a multi-wavelength
    observatory for gammaray burst astronomy, remains on schedule for a
    September, 2003 launch. Another MIDEX mission, the Full-sky Astrometric
    Mapping Explorer (FAME), did not pass confirmation review due to cost
    increases and was not approved for full-scale development. Selection of
    the MIDEX-5 and MIDEX-6 missions will occur in 2002, and an Announcement
    of Opportunity for MIDEX-7 and MIDEX-8 will be released in 2003. In the
    Small-class (SMEX) mission series, three NASA missions and two non-NASA
    Missions of Opportunity are sup

    [[Page 1028]]

    ported. The NASA missions include the Galaxy Evolution Explorer (GALEX),
    Two Wide-Angle Neutral Atom Spectrometers (TWINS), and the High Energy
    Solar Spectroscopic Imager (HESSI). The Missions of Opportunity are the
    Coupled Ion Neutral Dynamics Investigation (CINDI; a cooperative mission
    with the Air Force), and ASTRO E-2, an X-ray astronomy mission (in
    cooperation with Japan). ASTRO E-2 is a rebuild of ASTRO E, which was
    lost due to a failure of the Japanese launch vehicle in February, 2000.

        In the Discovery program, the Genesis mission was launched on August
    8, 2001; it has begun collecting samples of charged particles from the
    solar wind, and it will return these samples to Earth for analysis in
    calendar year 2004. Development activities continue on three other
    Discovery missions. The Comet Nucleus Tour (CONTOUR) will be launched in
    July 2002, and it will encounter two comets: comet Encke in calendar
    year 2003, and comet Schwassman Wachman-3 in calendar year 2006. The
    Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER)
    mission to orbit Mercury, and the Deep Impact mission to fly by and fire
    an impactor into comet Temple-1, are both scheduled to launch in early
    calendar year 2004.

        The New Millennium program is providing flight demonstrations of
    critical new technologies that will reduce the mass and cost of future
    science and spacecraft subsystems, while maintaining or improving
    mission capabilities. In calendar year 2003, the Nanosat Constellation
    Trailblazer (Space Technology-5, or ST-5) will undergo spacecraft and
    instrument integration and test in preparation for launch in calendar
    year 2004. Also in calendar year 2003, the Critical Design Review for
    ST-6 will be conducted, as will the Confirmation Review for ST-7, and
    the initial confirmation for ST-8.

        The President's 2003 Budget also provides funding for focused
    technology programs in each of the four major Space Science themes: the
    Astronomical Search for Origins, Structure and Evolution of the
    Universe, Solar System Exploration, and Sun-Earth Connections, which
    includes both the Living With A Star Program and the Solar Terrestrial
    Probes Program. These funds provide for early technology development in
    support of strategic missions such as the Next Generation Space
    Telescope and the Space Interferometry Mission. The goal is to retire
    technology risk early in a mission's life-cycle, before proceeding to
    full-scale development. Funds are also provided to continue on-going
    operations of approximately thirty spacecraft, and to conduct robust
    research and analysis, data analysis, and suborbital research campaigns.

        Biological and Physical Research.--The Biological and Physical
    Research Enterprise (BPRE) seeks to exploit the rich opportunities of
    space flight for fundamental research in the biological and physical
    sciences, as well as in commercial development of space, and conducts
    research to enable efficient and effective systems for protecting and
    sustaining humans in space. BPRE seeks to achieve advances in biological
    and physical sciences by understanding nature's forces in space, and
    achieve an understanding of the human experience in space.

        In late 2001, BPRE was created as NASA's fifth strategic enterprise.
    BPRE closed its first fiscal year with a significant record of
    accomplishment. It expanded its interagency research collaborations,
    establishing a new memorandum of understanding with the United States
    Department of Agriculture, conducting a joint research solicitation with
    the National Cancer Institute, and continuing work under 18 other
    agreements with the National Institutes of Health. A BPRE investigator
    received the Nobel Prize in physics for ground-based research that he
    plans to extend and expand on the International Space Station.
    Outfitting the International Space Station (ISS) for research began with
    the delivery of the Human Research Facility in March 2001. Two research
    equipment racks were delivered to the ISS in mid-April and an additional
    two at the beginning of Expedition 3 in August. BPRE initiated a program
    of research on the ISS to take advantage of available resources during
    the construction phase. The ISS Expedition 1 and 2 teams were able to
    exceed expectations for meeting research objectives of the planned
    experiments, with only one unsuccessful experiment due to technical
    reasons.

        In 2002, BPRE will continue to increase knowledge and demonstrate
    key technology capabilities for humans in space, address critical
    questions in crew health and safety, and materials science and
    commercial research payloads will be flown on both the Space Shuttle and
    aboard ISS. The Space Station research program is on track to deliver
    another five equipment racks on orbit by the end of calendar year 2002.
    BPRE also will complete definition studies leading to award of a
    contract to manage ISS utilization to a Non-Governmental Organization
    (NGO). Working with the scientific community, its advisory committees,
    and the Administration, BPRE will complete the development of research
    priorities across its portfolio of research endeavors to provide a basis
    for critical resource allocation decisions. In the area of public
    outreach and education, BPRE plans to develop electronic and printed
    educational materials that focus on biological and physical research.

        In 2003, BPRE will implement its research priorities and develop ISS
    flight facilities to achieve a prioritized and productive research
    program. BPRE will also work with Life Science Museum Network members to
    explore opportunities for the development of projects, special events,
    or workshops focused on the life sciences and biology-related research
    themes to attract and engage public audiences. In addition, BPRE will
    make available to wide audiences an online database of Commercial Space
    Center activities, including publications listings, patents, and other
    information useful to the general public.

        Earth Science.--The mission of NASA's Earth Science Enterprise (ESE)
    is to develop a scientific understanding of the Earth system and its
    response to natural and human-induced changes to enable improved
    prediction of climate, weather and natural hazards for present and
    future generations. ESE seeks to answer a question of fundamental
    importance to science and society: How is the Earth system changing, and
    what are the consequences for life on Earth? To do so, ESE is developing
    the interdisciplinary research field of Earth System Science, which
    recognizes that the Earth's land surface, oceans, atmosphere, ice
    sheets, and life itself all interact in a highly dynamic system. Earth
    system science is an area of research with immense benefit to the
    Nation, leading to new knowledge and tools that may improve weather
    forecasting, agriculture, urban and regional planning, environmental
    quality, and natural disaster management. ESE has established three
    goals to pursue in order to fulfill its mission: (1) Science--observe,
    understand, and model the Earth system to learn how it is changing, and
    the consequences for life on Earth; (2) Applications--expand and
    accelerate the realization of economic and societal benefits from Earth
    science, information, and technology; (3) Technology--develop and adopt
    advanced technologies to enable mission success and serve national
    priorities.

        In ESE Science, 2001 was another year of substantial accomplishment
    toward understanding the Earth system. Goddard Space Flight Center
    (GSFC) produced the first global record of the Earth's biosphere,
    showing the uptake and release of carbon by land and oceans continuously
    over three years. NASA-sponsored research showed that the growing sea

    [[Page 1029]]

    son over parts of the Northern hemisphere has lengthened over the past
    two decades, with an accompanying increase in lushness of vegetation.
    NASA and the EarthSAT Corporation released the first consistent 30-m
    resolution land cover map for the U.S., and are nearing completion of
    the global map. These data are from calendar year 1990 and provide a
    basis for comparison of future change; plans are being developed to
    repeat the process for calendar year 2001 and beyond. Results from a
    major NASA/NSF-led international research campaign indicate that
    aerosols from dust and pollution may be reducing evaporation and thus
    slowing the global water cycle. Results from comparing the 2000 and 1997
    Antarctic Mapping Missions have led to new estimates of change in the
    Antarctic ice sheet; ice in the Lambert glacier flows from the interior
    to the ``mouth'' where it reaches a rate of 1 kilometer per year. In the
    Northern hemisphere, NASA researchers identified patterns of change in
    sea ice extent over a twenty-year period; overall, Arctic sea ice extent
    has decreased since calendar year 1978. Continued monitoring of global
    ocean topography showed that the Pacific Decadal Oscillation governs
    climate impacts of the Pacific in non-El Nino/La Nina years, and allowed
    the prediction of last winter's chill across the northern U.S. and
    relative warmth across the South. ESE also made major advances in
    computing for climate modeling, using a partnership among two NASA
    Centers and Silicon Graphics, Inc. to simulate 900 days of Earth's
    climate in one day, up from the prior capability of 70 days per day;
    performance on end-to-end climate simulation improved ten-fold. This
    greatly enhances climate modelers' ability to perform the multiple runs
    of many years of climate simulations needed to generate useful
    projections of climate change.

        In ESE Applications, ESE has entered into a variety of partnerships
    that will apply the goods and services made possible by ESE's research.
    ESE provides QuikSCAT data in real time to the National Oceanic and
    Atmospheric Administration (NOAA) to improve marine weather forecasting,
    and has used these data to show that severe storms forming over the
    oceans can be predicted two days in advance. ESE is working with the
    Federal Emergency Management Agency (FEMA) to use remote sensing tools
    to update their flood plain maps throughout the U.S. In a partnership
    called Agriculture 2020 with the U.S. Department of Agriculture (USDA)
    and four growers associations representing 100,000 farmers, ESE is
    demonstrating how to increase crop productivity, reduce risks to crop
    health, and manage environmental impacts. With the National Institutes
    of Health, we are exploring the use of satellite data to predict spread
    of infectious diseases such as malaria that are highly influenced by
    weather and climate. Throughout the summer, three ESE satellites tracked
    devastating wildfires in the western U.S., providing data to the U.S.
    Forest Service (USFS) and regional authorities. As a result, USFS is
    investing in direct broadcast receiving stations to rapidly acquire data
    from NASA's Terra satellite.

        In ESE Technology, the Enterprise's first New Millennium Program
    satellite to demonstrate a variety of new technologies for Earth Science
    successfully completed all its demonstration tasks (save one high-risk
    propulsion task scheduled for near the end of mission life). These
    include a new instrument to produce a Landsat-type sensor one-fourth the
    size of the current Landsat 7 instrument, and the first hyperspectral
    imager in space, which views the land surface in hundreds of spectral
    channels rather than the conventional five to seven channels. Sponsored
    technology research with universities, industry and other government
    laboratories moved 35% of ESE's new remote sensing instrument concepts
    one step closer to reality on an established scale of technology
    maturity. These advances will substantially reduce the cost and enhance
    the capability of new satellites over the next decade or more. ESE also
    began formation flying of four land imaging satellites, demonstrating
    that several smaller satellites can be operated in tandem to
    dramatically increase spatial and temporal coverage.

        ESE is in the midst of deployment of the Earth Observing System
    (EOS), a set of spacecraft and associated interdisciplinary science
    investigations to initiate a long-term data set of key parameters
    required for the study of global climate change. The first six EOS
    satellites are already in orbit, including Jason-1 and SAGE III,
    launched in December 2001. The remaining EOS satellites will be launched
    through calendar year 2004, including Aqua (calendar year 2002) to study
    the water cycle and atmospheric circulation, and Aura (calendar year
    2004) to probe the chemistry of the upper and lower atmosphere.
    Complementing EOS is a series of small, focused Earth System Science
    Pathfinder missions to explore Earth system processes never before
    examined globally from space. Data from the EOS satellites already in
    orbit are being acquired, processed, and distributed by the EOS Data and
    Information System (EOSDIS), which is currently handling more than 1
    terabyte of data per day. EOSDIS handled 12.3 million user queries for
    over 15 million products in calendar year 2001. EOSDIS continues to
    evolve as new satellites are launched, and as new partners are added to
    produce data products with innovative applications.

        As it deploys EOS, ESE is also planning for the future. ESE and U.S.
    Geological Survey (USGS) released a request for proposal for Landsat
    Data Continuity Mission to succeed Landsat 7; it is being implemented as
    a commercial data purchase. ESE is also planning for the transition of
    several of its key research observations to the Nation's weather
    satellite system. The Department of Defense (DoD), NOAA and NASA have
    established an Integrated Program Office (IPO) to create a converged
    civilian and military weather satellite system called the National
    Polar-orbiting Operational Environmental Satellite System (NPOESS) to
    replace the present generation of separate systems. NASA and the IPO are
    jointly funding the NPOESS Preparatory Project (NPP) that will
    simultaneously continue key measurements begun by EOS and demonstrate
    instruments for NPOESS. The NPP will save money for both NASA and NOAA
    by combining essential atmospheric and Earth surface observations on a
    single platform, and by seeking to meet both climate science and
    operational weather requirements with the same advanced instruments.

        ESE data products and research are a major contribution to the U.S.
    Global Change Research Program, an interagency collaboration overseen by
    the Committee on Natural Resources of the National Science and
    Technology Council. NASA ESE will also contribute to the new Climate
    Change Initiative, a multiagency effort with strong focus on outcomes.
    Because Earth science is inherently global in scope, ESE is engaged in a
    variety of international partnerships with individual nation's space
    agencies, and with international consortia such as the World
    Meteorological Organization. ESE seeks and receives scientific advice on
    a broad range of topics from the various boards and committees of the
    National Research Council. These partnerships, together with those
    above, ensure that NASA's Earth Science Enterprise conducts research at
    the frontiers of Earth science on questions of practical importance to
    the Nation.

        Aerospace Technology.--The Aerospace Technology (AST) Enterprise
    mission is to pioneer the identification, development, verification,
    transfer, application, and commercialization of high-payoff aerospace
    technologies and the development of broad, crosscutting revolutionary
    innovations critical to a number of NASA missions. The Enterprise plays
    a key role in: 1) maintaining a safe and efficient national aviation
    system, 2) enabling affordable, reliable space transportation systems,
    and 3) developing basic technologies for a broad range of space
    applications. Research and development pro

    [[Page 1030]]

    grams conducted by the Enterprise contribute to NASA's science and
    exploration missions, national security, economic growth, and the long-
    term competitiveness of American aerospace companies. The Enterprise
    directly supports national policy in both aeronautics and space as
    directed in the President's Goals for a National Partnership in
    Aeronautics and Research Technology, the National Space Policy, and the
    National Space Transportation Policy.

        A modern air and space transportation system is fundamental to our
    national economy, quality of life, and security of the United States.
    For 75 years, a strong base for aerospace technology research and
    development has provided enormous contributions to this system,
    contributions that have fostered the economic growth of our Nation and
    provided unprecedented mobility for U. S. citizens. Although major
    technical advances have made our Nation's air and space transportation
    system the largest and best of its kind, the future holds critical
    challenges to its continued growth and performance. Because the U. S.
    air and space transportation system serves both the public good and
    critical national security needs, ensuring the continued health and
    preeminence of that system is a key issue for the future of the Nation.

        Although NASA technology benefits the aerospace industry directly,
    the creative application of NASA's advanced technology to disparate
    design and development challenges has made numerous contributions to
    other areas such as the environment, surface transportation, and
    medicine.

        In order to develop the aerospace systems of the future,
    revolutionary approaches to system design and technology development
    will be necessary. Pursuing technology fields that are in their infancy
    today, developing the knowledge bases necessary to design radically new
    aerospace systems, and performing efficient, high-confidence design and
    development of revolutionary vehicles are challenges that face us in
    innovation. These challenges are intensified by the demand for safety in
    our highly complex aerospace systems.

        The President's 2003 Budget provides the resources necessary to
    maintain the progress required to achieve a 21st Century aviation system
    that is safe, environmentally friendly, efficient and meets the growing
    demands for increased and predictable performance. The President's 2003
    Budget also supports technology development for space transportation
    systems that are safer and significantly less costly than today's
    systems. The structure of the Aerospace Technology budget has been
    changed so that the budget lines are directly linked to the Enterprise
    Strategic Goals. The first goal, Revolutionize Aviation, addresses
    fundamental, systemic issues in the aviation system to ensure continued
    growth and development appropriate to the needs of the national and
    global economies. These systemic issues--safety, capacity, environmental
    compatibility, and mobility--cut across markets including large subsonic
    civil transports, air cargo, commuter and general aviation. NASA
    coordinates its investments and technology objectives in this area with
    the Federal Aviation Administration (FAA) and the Department of Defense
    through the National Research and Development Plan for Aviation
    Security, Efficiency, and Environmental Compatibility. In 2003, the
    President's Budget provides for the demonstration of several advanced
    technologies that when implemented will result in a significant
    reduction in aviation accidents. Specific flight evaluations will
    include an integrated Synthetic Vision System and Runway Incursion
    Prevention System intended for use on commercial and business aircraft,
    a next-generation cockpit weather information digital datalink and
    turbulence awareness system, and a smart icing management system which
    will automatically activate and manage an aircraft's ice protection
    systems. In addition, ground-based demonstrations of an advanced vehicle
    health management system, an engine disk crack detection monitoring
    system and recovery methods for flight critical systems will be
    accomplished. The Administration's request also provides for continued
    development of the technologies necessary to reduce the environmental
    impact of today's aircraft. The sector testing of a jet engine combustor
    that could reduce nitrous oxide emissions by 70 percent will be
    complete. Selection of contractors to proceed with full annular testing
    for large and regional jet engines will also be complete. Additionally,
    the Administration's request includes funding for the development of a
    broad suite of advanced technologies that will provide the basis for
    future emission reductions including carbon dioxide. The request also
    includes the continuation of the noise reduction technology that in
    calendar year 2007 will reduce the perceived aircraft noise pollution by
    a factor of two from the calendar year 1997 baseline set by the
    International Civil Aviation Organization (ICAO). The budget request
    also continues to transfer to the Federal Aviation Administration
    technologies required to safely increase the use of the National
    Airspace System (NAS). In order to define future technology investments
    in this area, the Virtual Airspace Modeling and Simulation project will
    provide state-of-the-art models of the airspace system which have the
    capability to model the dynamic effects of interactive agents in the
    NAS. These models will provide the capability to assess the economic
    impact of new technologies on the operational performance of the NAS and
    thus guide future technology development. The budget request continues
    the Small Aircraft Transportation System (SATS) demonstration program.
    In 2003, SATS will select candidate technologies for experimental flight
    evaluation based on their impact on mobility--either through reduced
    system cost, improved doorstep-to-destination time, increased trip
    reliability, and/or improved safety--and complete initial lower landing
    minimum and higher volume flight experiments. Building on its altitude
    world-record-setting performances, the Environmental Research Aircraft
    and Sensor Technology (ERAST) project will demonstrate a solar power
    unpiloted air vehicle with the ability to fly 14 hours above 50,000
    feet. The accomplishment of this goal could have significant impact on
    the application of these systems in disaster relief, communications,
    environmental sensing, and defense.

        The second goal, Advance Space Transportation, will create a safe,
    affordable highway through the air and into space by improving safety,
    reliability, and operability, and significantly reducing the cost of
    space transportation systems. With the creation of the Integrated Space
    Transportation Plan (ISTP), NASA defined a single, integrated investment
    strategy for all its space transportation efforts, including Space
    Shuttle safety investments, the Space Launch Initiative (SLI), and 3rd
    Generation Space Transportation Technology. By investing in a sustained
    progression of research and technology development, NASA will enable
    future generations of reusable launch vehicles and in-space
    transportation systems that will surmount the Earth-to-orbit challenge
    and allow less costly, more frequent, and more reliable access to
    neighboring planets and the stars beyond. As planned in the 2002 Budget,
    the President's 2003 Budget request includes an increase in funding for
    the Space Launch Initiative (SLI), which supports the 2nd Generation
    Reusable Launch Vehicle (RLV) Program. In 2001, NASA awarded 23
    contracts under the 2nd Generation RLV Program for study and risk
    reduction activities across many technical areas, including: airframes,
    vehicle subsystems, operations, integrated vehicle health management,
    flight mechanics, NASA-unique systems, and propulsion. In 2003, the Main
    Engine Prototype Critical Design Review and the Systems Requirements
    Review will be complete and the Architecture Systems Requirements
    Document will be baselined. Upon completion of these activities, NASA
    will

    [[Page 1031]]

    downselect to a minimum of two space transportation architectures for
    continued development based on their ability to meet safety and
    affordability goals. This selection will determine what architectures
    and critical technology developments will be continued through 2006. The
    successful completion of 2nd Generation RLV Program risk reduction and
    technology development will enable a mid-decade competition to
    transition all of NASA's launch needs, including human space flight, to
    safer, lower cost, commercially competitive, privately operated vehicles
    at the turn of the decade. In 3rd Generation Space Transportation
    Technology, the Department of Defense and NASA have collaborated on an
    integrated science and technology plan for hypersonics research, the
    National Hypersonic Science and Technology Plan (NHP), which defines a
    national effort to address numerous challenges. The plan addresses
    airbreathing propulsion or, in some cases, combined rocket/airbreathing
    (RBCC) or turbine/airbreathing propulsion (TBCC) cycles. While pure
    rockets have already achieved hypersonic speeds, airbreathing
    technologies could offer significant benefits over rocket propulsion in
    performance and cost. In 2003, NASA will complete the independent
    evaluation of three competing, revolutionary hypersonic propulsion
    technology systems demonstrations, including an RBCC engine, a TBCC
    engine and a scramjet engine.

        The third goal, Pioneer Technology Innovation, focuses on broad,
    crosscutting innovations critical to a number of NASA missions and to
    the aerospace industry in general. Pursuing technology fields that are
    in their infancy today, developing the knowledge bases necessary to
    design radically new aerospace systems, and developing tools for
    efficient, high-confidence design and development will enable a
    revolution in aerospace. The Administration's request includes a
    significant investment in computing and information technology
    developments and also increases investment in biotechnology and
    nanotechnology--the revolutionary technologies of the 21st Century. To
    ensure the highest quality research and strong ties to NASA's missions--
    Space Science, Earth Science, Biological and Physical Research, Human
    Space Flight, and Aerospace Technology--these investments will be guided
    by technology development agreements signed by customers in other NASA
    Enterprises.

        Beginning in 2002, NASA will have the National Academy of Sciences
    undertake reviews of one of these three program areas--Revolutionize
    Aviation, Advance Space Transportation, and Pioneer Technology
    Innovation--every three years. These reviews will provide independent
    assessments of the quality of NASA's technology research and program
    planning, whether the research can be performed by universities or
    corporations outside NASA, and how well NASA's technology research
    integrates with customer needs. In each of these program areas, NASA
    will also seek to reduce institutional costs at it field centers so more
    funds can be invested in technology research through openly competed
    NASA research announcements and through university and industry
    partnerships.

        The fourth goal, Commercialize Technology, extends the commercial
    application of NASA technology for economic benefit and improved quality
    of life. By partnering with both aerospace and non-aerospace industry as
    well as academia, the full range of NASA's assets--technological
    expertise, new technologies, and research facilities--are made available
    to help the Nation.

        Academic Programs.--Academic Programs has two components: (1)
    Education Program and (2) Minority University Program. Since the
    creation of NASA, the agency has made a substantial commitment to
    education. NASA's contribution to education has been and is based on the
    Agency's inspiring mission, specialized workforce, close working
    relationship with the research and education community, and unique
    world-class facilities. Based on these attributes, NASA has created a
    comprehensive education program containing a portfolio of activities
    directed toward education at all levels. The guidance for the Education
    Program stated in the NASA Strategic Plan: ``Educational Excellence: We
    involve the educational community in our endeavors to inspire America's
    students, create learning opportunities, and enlighten inquisitive
    minds.'' NASA's Education Program brings students and educators at all
    levels into its missions and its research as participants and partners,
    providing opportunities for a diverse group of students and educators to
    experience first hand involvement with NASA personnel, facilities, and
    research and development activities.

        The Minority University Research Program has a goal to: expand
    NASA's research base by strengthening the research capabilities of
    minority universities and colleges; contribute to the scientific and
    technological workforce; and promote educational excellence. The range
    of activities conducted under this program will continue to capture the
    interest of all students in science and technology, develop talented
    students at the undergraduate and graduate levels, provide research
    opportunities for students and faculty members at NASA centers, and
    strengthen and enhance the research capabilities of the Nation's
    colleges and universities.

        Together, these two components of the Academic Programs budget
    provide guidance for the Agency's interaction with both the formal and
    informal education community.

        In 2001, this appropriation provides funding for mission support and
    includes: safety, mission assurance, engineering and advanced concepts
    activities supporting agency programs; salaries and related expenses in
    support of research in NASA field installations; design, repair,
    rehabilitation and modification of institutional facilities and
    construction of new institutional facilities; and other operations
    activities supporting conduct of agency programs.

        Since 2002, NASA has implemented a two-appropriation budget
    (excluding the Inspector General account). The two-appropriation budget
    (Human Space Flight (HSF) and Science, Aeronautics and Technology (SAT))
    is NASA's first step at transitioning to a full cost budget. While full
    cost will ultimately integrate institutional and programmatic funds into
    a single budget, that integration is done in a step-wise manner, by
    providing for a mission support budget line under each Enterprise and
    eliminating the present mission support appropriation. This initial step
    will begin to recognize, budget, and track direct full time eqivalent
    (FTE) personnel associated at the Enterprise level and then use this FTE
    data to distribute other-than-direct (OTD) institutional costs (Research
    and Program Management and non-programmatic Construction of Facilities)
    using the relative percentages of direct FTE's by Enterprise.

        This means the distribution of the OTD resources takes advantage of
    a basic assumption, to be used prior to the existence of cost and
    service pools, that FTE's are a reasonable relative indicator at the
    Enterprise level of required facility and institutional capabilities.
    Taking this step will help program/project personnel and decision makers
    begin to understand the potential magnitude of institutional funds that
    are associated with each Enterprise in preparation for the day when full
    cost budgeting will distribute these funds most appropriately to the
    project level via the appropriate cost/service pools.

        Beginning in 2002, there is no longer a Mission Support account.
    Institutional costs will be budgeted within HSF and SAT (as discussed
    above) and safety, mission assurance and engineering will be budgeted
    within the HSF account.

        NASA plans to control personnel levels through full time permanent
    (FTP) civil servant positions while continuing to track full time
    equivalent positions, as done in the past. This will allow NASA more
    flexibility in the use of non-permanent positions for short-term
    technical needs as well as co-op and intern programs.

    Performance Objectives

        Research and program management.--In 2001, this activity provided
    for the salaries, travel support, other personnel expenses of the entire
    NASA civil service workforce, and includes vital support to the physical
    plant at the Centers and at NASA Headquarters.

        Construction of facilities.--In 2001, this activity provided for
    facility construction activities to preserve NASA's infrastructure and
    enable NASA's missions; environmental compliance and restoration
    activities, design of facilities projects, and advanced planning and
    critical functional leadership activities related to future facilities
    needs. Activities in support of construction projects to repair,
    revitalize and modernize the basic infrastructure and institutional
    facilities at NASA centers will continue with the major focus on
    eliminating safety-related concerns. Increasing attention is being given
    to activities in support of environmental compliance and restoration
    requirements.
