        This appropriation provides funding for human space flight
    activities, including development of the Space Station, the Space
    Station research program, and operation of the Space Shuttle. This
    includes support of planned cooperative activities with Russia, upgrades
    to the performance and safety of the Space Shuttle, and required
    construction projects in direct support of Space Station and Space
    Shuttle programs.

    Performance Objectives

        Space Station.--The Space Station will be an international
    laboratory in low Earth orbit on which American, Russian, Canadian,
    European, and Japanese astronauts will conduct unique scientific and
    technological investigations in a microgravity environment. The
    Administration continues to be strongly committed to development of the
    International Space Station, and the preservation of the partnerships
    between the United States, Russia, Europe, Japan, and Canada. The
    proposed budget provides multi-year funding for the complete development
    of the Station within the annual $2.1 billion ceiling and the $17.4
    billion development constraints, with Station assembly beginning in late
    1997 and finishing by 2002. The Administration continues to monitor
    progress through this crucial development period and will consider
    future funding, schedule, or content adjustments if they prove necessary
    to minimize program costs, maintain international participation, and
    ensure a Station capable of continuous scientific and technological
    research and permanent human presence in space. In 1996, node and
    laboratory module fabrication neared completion, and qualification
    testing of flight hardware components began. Activities are well
    underway to support crew training, payload processing, and hardware
    element processing requirements. In 1997, final fabrication of flight
    hardware, qualification testing, and assembly and integration will be
    the focus of the program. First element launch is scheduled for late
    1997. The FY 1998 budget incorporates all elements of the $2.1 billion
    per year program into the Human Space Flight appropriation. This will
    allow maximum flexibility in providing a balanced program.

        U.S./Russian Cooperative Program.--The United States and Russia are
    continuing a program of joint space missions. In 1996, three Shuttle
    flights to Mir took place, highlighted by the 181 day stay of Astronaut
    Shannon Lucid on the Mir

    [[Page 966]]

    Space Station. In 1997, American astronauts will have a continuing
    presence aboard the Mir conducting scientific research. Flight hardware
    to conduct experiments has been and will continue to be placed on the
    Mir. These flights provide valuable opportunities to gain experience in
    working with our Russian partners, which will be crucial to the success
    of building and operating the International Space Station. These flights
    will continue in FY 1997, with three additional flights planned. Two
    additional flights are planned in FY 1998, completing phase I of this
    cooperative precurser to Space Station.

        Payload and Utilization Operations.--These funds will support the
    mission planning and hardware preparation activities required to support
    the payload and experiment infrastructure, including the spacelab. In
    1997-1998, 2 module missions (MSL-1 and Neurolab) will be flown, along
    with 3 pallet missions. The Spacelab program is scheduled to be
    terminated in 1998, following the Neurolab mission.

        Activities funded by the Payload Processing budget support the
    technical expertise and facilities necessary to perform payload buildup,
    test and checkout, integration, servicing, transportation and
    installation into the launch vehicle. In FY 1997, over 30 major and
    secondary payloads will be supported; in FY 1998, more than 20 major and
    secondary payloads will be supported. The Advanced Projects program
    develops technologies to enhance crew safety for the Space Shuttle and
    International Space Station, implements improvements to reduce cost of
    space flight operations, and pursues advanced technology developments
    for future human space flight requirements. Under this program, the X-38
    experimental vehicle is being designed to demonstrate the technology and
    processes required to produce a crew return vehicle for the
    International Space Station. The Engineering and Technical Base provides
    basic engineering and technical capabilities to support the NASA mission
    assigned to the programs carried out by the Human Space Flight Centers.
    These funds support a core environment dedicated to multiprogram
    laboratories, test facilities and associated systems, including a skill
    base to respond to research, testing and simulations.

        Space Shuttle.--The Space Shuttle is a reusable space vehicle that
    provides several unique capabilities to the United States space program.
    These include launching spacecraft and retrieving payloads from orbit
    for reuse, servicing and repairing satellites in space, safely
    transporting humans to and from space, and operating and returning space
    laboratories. In 1996, eight Shuttle missions were accomplished,
    including the three docking missions between the Space Shuttle and the
    Russian Mir Space Station. Activities supporting consolidation of
    Shuttle contracts into one Space Flight Operations contract were
    completed in FY 1996. This will result in significant reductions in the
    cost of operating the Space Shuttle through FY 2000 and beyond, with no
    impact on safety, performance or schedule.

        In 1997, seven shuttle flights are planned. Continued emphasis will
    be placed on enhancements to the safety and performance of the Space
    Shuttle. Upgrades to the shuttle to increase its reliability and
    maintainability will be continued. In FY 1998, seven shuttle flights are
    planned, including two assembly flights for the International Space
    Station. Completion and first flight of major engine upgrades will also
    occur.

        This appropriation provides for the research and development
    activities of the National Aeronautics and Space Administration. Funds
    are included for the construction, maintenance, and operation of
    programmatic facilities.

    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 a base program of research
        and development activities, including research and flight mission
        activities, and major flight missions which provide major space
        based facilities. In 1996, several scientific discoveries rocked
        fundamental theories and re-opened discussion of long-held beliefs.
        Among the highlights were the discovery of evidence in a meteorite
        believed to have come from Mars that may indicate life began on Mars
        early in its history; the discovery of a possible subsurface ocean
        on Europa; and, the possible discovery of deep frozen lakes on the
        south pole of the Earth's moon.
            To capitalize on these enormous successes during the past year,
        the NASA budget request for FY 1998 highlights the Origins program.
        The program focuses on fundamental questions regarding the creation
        of the universe and planetary systems, and the possibility of life
        beyond Earth. A strategy for addressing these questions would
        involve returning surface samples from Mars; visiting comets and
        other planetary bodies; and deploying powerful telescopes to detect
        Earth-like planets elsewhere in our galaxy. NASA's Origins program
        is responsive to the President's new civil space policy and is a
        vital component of the Administration's investment strategy in
        science and technology.
            Development activities will continue in 1997-1998 on the
        Advanced X-ray Astrophysics Facility (AXAF) in support of a launch
        in late 1998. Funding was included in FY 1996 and FY 1997 to
        complete development of the Cassini spacecraft, scheduled for launch
        in October, 1997. The Global Geospace Science mission spacecraft,
        Wind and Polar, are currently operating and providing data on the
        interactions between the Sun and the Earth. Development activities
        continue on the Relativity (Gravity Probe-B) mission, which remains
        ahead of schedule for launch in 2000. Funding was also included to
        complete definition activity on the Space Infrared Telescope
        Facility (SIRTF) in 1997 and initiate development activities in FY
        1998. Development activities on the Thermosphere, Ionosphere,
        Mesophere Energetics and Dynamics (TIMED) mission are scheduled to
        begin in mid-1997. Development activities on the Stratospheric
        Observatory for Infrared Astronomy (SOFIA) have received continued
        support. A commercial operator for development, modification and
        operation of the SOFIA aircraft was selected in December 1996.
        Several significant scientific discoveries were reported in 1996
        based on data gathered from the Hubble Space Telescope (HST), and
        similar results are anticipated in the future. The second HST
        servicing mission in February 1997 will provide two new science
        instruments and other servicing requirements as needed. Galileo's
        highly successful, two-year tour of Jupiter and its moons will
        continue through 1998.
            In Explorer missions, the Fast Auroral Snapshot (FAST) was
        launched in August 1996. Development activities continue on the
        Advanced Composition Explorer (ACE) for a launch in 1997, and on the
        Far Ultraviolet Spectroscopy Explorer (FUSE) for a launch in 1998.
        Definition is underway on the Microwave Anisotropy Probe (MAP) and
        Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) Medium-
        Class Explorer (MIDEX) missions. Selection of candidate missions for
        the Small-(SMEX) and MIDEX-class Explorer programs continues. These
        missions emphasize reduced mission costs and accelerated launch
        schedules.
            The Mars Global Surveyor was launched in November 1996, and
        funds are requested for the development of future Mars missions in
        1998 and beyond. The first two Discovery-class missions were
        launched in 1996: the Near-Earth Asteroid Rendezvous was launched in
        February 1996; and the Mars Pathfinder was launched in December
        1996. The Lunar Prospector mission is scheduled for launch in 1997,
        and the Stardust mission is to be launched in 1999. Funding is also
        included for future Discovery-class missions. The New Millennium
        program is underway to provide flight demonstrations for critical
        new technologies which will greatly reduce the mass and cost of
        future science instruments and spacecraft subsystems, while
        maintaining or improving mission capabilities. Development
        activities continue on the Deep Space Mission-1 and -2, scheduled
        for launch in June 1998 and January 1999, respectively.
            The Space Science program assumed most of the responsibility for
        Agency-wide core technology development following dissolution of the
        Office of Space Access and Technology. Space Science is also
        undertaking an aggressive technology development effort to enable
        new missions to the outer planets, and to search for Earth-like
        planets around nearby

    [[Page 968]]

        stars. New technologies are also being pursued to enhance our
        capability to explore Mars robotically, and perhaps to confirm the
        past or current presence of life on that planet.

        Life and Microgravity Science.--This program uses the microgravity
    environment of space to conduct basic and applied research to understand
    the effect of gravity on living systems and to conduct research in the
    areas of fluid physics, materials science and biotechnology. In 1996,
    six shuttle missions involving materials and life sciences experiments
    were conducted, including two Spacelab missions and three NASA/Mir
    missions. In addition to conducting basic and applied research, these
    missions have provided the opportunity to refine the definition, design,
    and development of experiment hardware planned for use on the
    International Space Station. In 1997, four shuttle missions including
    the Materials Sciences Laboratory (MSL-1) mission and three NASA/Mir
    missions are planned. In 1998, the NASA/NIH Neurolab mission is planned,
    which will continue the agency's efforts to expand its collaborative
    activities with the National Institutes of Health and other Federal
    agencies to maximize the return on science investments. In addition to
    this mission, the program will be supporting the launch of the Alpha
    Magnetic Spectrometer (AMS). The Space Station research program and the
    remaining two NASA/Mir missions will be incorporated into the Human
    Space Flight Appropriation within the Space Station program.

        Mission to Planet Earth.--The purpose of NASA's Mission to Planet
    Earth (MTPE) enterprise is to understand the total Earth system and the
    effects of natural and human-induced changes on the global environment.
    MTPE is pioneering the new interdisciplinary field of research called
    Earth system science, which recognizes that the Earth's land surface,
    oceans, atmosphere, ice sheets and biota are both dynamic and highly
    interactive. Earth system science is an area of research with the
    potential for immense benefit to the nation, yielding new knowledge and
    tools for weather forecasting, agriculture, urban and land use planning,
    and other areas of economic and environmental importance. In concert
    with other agencies and the global research community, MTPE is providing
    the scientific foundation needed for the complex policy choices that lie
    ahead on the road to sustainable development. MTPE has established three
    broad goals to fulfill its purpose: (1) expand scientific knowledge of
    the Earth system using NASA's unique capabilities from the vantage
    points of space, aircraft and in situ platforms; (2) disseminate
    information about the Earth system; and, (3) enable productive use of
    MTPE science and technology in the public and private sectors.

        The Earth Observing System (EOS), the centerpiece of Mission to
    Planet Earth, is a program of multiple spacecraft missions (the AM, PM,
    Chemistry series, Landsat 7, and others) and interdisciplinary science
    investigations aimed at providing a 15 year data set of key parameters
    needed to understand global climate change. The first EOS satellite
    launches will be in 1998. Preceeding EOS are a number of individual
    satellite and Shuttle-based missions which are helping to reveal basic
    processes. The Upper Atmosphere Research Satellite, launched in 1991,
    collects data on atmospheric chemistry. The Total Ozone Mapping
    Spectrometer instrument, launched in 1978 and 1991, measures ozone
    distribution and depletion. Two total ozone mapping spectometer
    instruments were launched in 1996, one on the Japanese Advanced Earth
    Observing System (ADEOS) mission and the other on a dedicated U.S. Earth
    probe. France and the U.S. collaborated on the Ocean Topography
    Experiment (TOPEX/Poseidon), launched in 1992, to study ocean topography
    and circulation. The NASA scatterometer, also launched on the Japanese
    ADEOS in 1996, maps ocean winds. In 1997 the Tropical Rainfall Measuring
    Mission (TRMM) will measure tropical precipitation. Complementing EOS
    will be a series of small, rapid development Earth System Science
    Pathfinders (ESSP). Data from MTPE will be captured from the satellites,
    processed into useful data products, and broadly distributed by the EOS
    Data and Information System (EOSDIS). In FY 1997, NASA initiated a data
    purchase program designed to acquire data sets from private sources that
    are necessary to accomplish the broad research goals of Earth system
    science. MTPE assumed responsibility for the small spacecraft technology
    initiative (Lewis and Clark) and the commercial remote sensing program.
    The MTPE science program is essential to the discovery of new concepts
    and to the design of future missions. The MTPE research is coordinated
    through the U.S. Global Change Research Program (USGCRP), the Committee
    on the Environment and Natural Resources (CENR) Subcommittee on Global
    Change Research, and the various boards and committees at the National
    Academy of Sciences.

        Aeronautics and Space Transportation Technology.--The goal of this
    enterprise is to pioneer high-payoff, critical technologies with
    effective transfer of design tools and technology products to industry
    and government.

        Within Aeronautics, the High Speed Research Program continued to
    develop technologies to establish the viability of an economical and
    environmentally sound High Speed Civil Transport. This vehicle--if built
    by U.S. industry--could promote U.S. leadership in long-range commercial
    air travel markets of the next century. Development of this vehicle
    could offer returns of $200 billion in sales and 140,000 high-quality
    jobs for the United States. In FY 1996, a preliminary conceptual
    definition of a supersonic transport technology configuration was
    selected and efforts to develop these technologies continue. In FY 1996,
    in cooperation with the FAA, the Advanced Subsonics Technology program
    significantly expanded its efforts in critical air traffic technologies.
    Research will continue to emphasize aviation capacity as well as
    improving the environment through noise and emissions reductions.
    Funding is included to continue development of high payoff technologies
    enabling a safe, highly productive global air transportation system with
    reduced environmental impact.

        In FY 1996, the High Performance Computing and Communications
    Program achieved sustained multidisciplinary application speeds never
    before reached by any NASA application. Funding is included to continue
    NASA's leadership role in this vital area. As part of the HPCC program,
    the President's FY 1998 budget proposes to provide $100 million each
    year for the next three years to support the new Next Generation
    Internet initiative. The programs goal is to develop a research network
    capable of achieving speeds of 100 to 1,000 times faster than today's
    Internet and yield large gains in the quality of service. This
    initiative will involve several Federal agencies including the
    Departments of Defense, Energy, and Commerce, the National Science
    Foundation, and NASA. NASA's contribution to this effort is $10 million
    annually for three years. In FY 1997, research activities within the
    research and technology base continue to develop innovative concepts,
    explore new areas of theory and create the computational models of the
    aeronautical principles that will lead to more efficient design and
    operation of advanced aerospace systems. NASA will continue to operate
    critical national facilities for aeronautical research in support of
    industry, Department of Defense and other NASA programs.

        The Space Transportation Technology program is developing new
    technologies aimed at revitalizing access to space. The technologies
    targeted will reduce launch costs dramatically over the next decade, and
    increase safety and the reliability of current and future generation
    launch vehicles. New performance plateaus for in-space propulsion will
    be estab-

    [[Page 969]]

    lished, while reducing the cost and weight of launch vehicles. In 1996,
    the Reusable Launch Vehicle (RLV) Program continued to pursue technology
    development and concept definition activities in support of next-
    generation reusable systems, focusing on the X-34 and X-33 flight
    demonstrators. The decision was made to proceed with Phase II of the X-
    33 program. Funding for the RLV program is included to continue
    technology development in preparation for the flight of technology
    demonstrators. The Advanced Space Transportation Program (ASTP) is
    developing key technologies to dramatically reduce space transportation
    costs across the mission spectrum. ASTP will focus on technological
    advances with the potential of reducing launch costs beyond RLV goals,
    as well as developing technology required to support NASA strategic
    needs that are not addressed by RLV.

        The Commercial Technology Program's focus in FY 1996 has been to
    invest 10 percent of the NASA R&D budget in commercial partnerships with
    industry. Based on experience to date, these commercial partnerships are
    expected to increase the return on the government's R&D investment,
    allowing NASA to do more with limited funds, and strengthen the
    international competitiveness of key industry sectors. In FY 1997 and
    1998, the program will emphasize increasing commercial partnerships with
    industry and continue to refine a technology and partnership database.

        Mission Communication Services.--The primary goal of this
    operational program is to provide highly reliable, cost-effective
    telecommunications services in support of NASA's science and aeronautics
    programs. Other U.S. agencies, international space-faring agencies, and
    U.S. commercial enterprises are supported on a reimbursable basis.
    Ground network, space network, and mission systems are provided under
    this program in support of planetary, deep space, Earth-orbiting,
    aeronautics, and suborbital systems.

        Academic Programs.--The goal of this program is to promote
    excellence in America's education system through enhancing and expanding
    scientific and technological competence. NASA's education programs span
    from the elementary through graduate levels, and are directed at
    students and faculty. The goal of the Minority University Research
    Program is to expand opportunities for talented students from
    underrepresented groups who are pursuing degrees in science and
    engineering, and to strengthen the research capabilities of minority
    universities and colleges. 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.

        The FY 1998 budget proposes multi-year appropriations in Science,
    Aeronautics, and Technology for development of a Space Infrared
    Telescope Facility (SIRTF), a Stratospheric Observatory for Infrared
    Astronomy (SOFIA), and an X-33 launch vehicle technology demonstrator.
    The multi-year funding will ensure the stability to manage and execute
    these programs within their budget and schedule commitments.

        This appropriation provides funding for mission support and
    includes: safety, reliability and quality assurance activities
    supporting agency programs; space communication services for NASA
    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.

    Performance Objectives

        Safety, Reliability and Quality Assurance.--The goal of this program
    is to assure the safety and quality of NASA missions through the
    development, implementation and oversight of Agency-wide safety,
    engineering, reliability, maintainability, and quality assurance
    policies and procedures.

        Space Communication Services.--Activities included in this program
    provide for the tracking, telemetry, command, data acquisition,
    communications and data processing required by NASA flight projects. In
    1996-1998, the networks and support systems that accomplish these tasks
    will continue operation. Completion of the upgrade of the Tracking and
    Data Relay Satellite (TDRS) White Sands Complex and early development of
    the TDRS Replenishment Spacecraft occurred and will continue in 1997 and
    1998. The FY 1998 budget proposes multi-year appropriations for
    development and launch of three Tracking and Data Relay Satellite (TDRS)
    replenishment spacecraft. The multi-year funding will support NASA's
    plans for the TDRS fixed price spacecraft contract with industry.

        Research and Program Management.--This activity provides 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.--This activity provides for: facility
    construction activities to preserve NASA's core infrastructure;
    environmental compliance and restoration activities, design of
    facilities projects, and advanced planning related to future facilities
    needs. In 1996-1998, activities in support of discrete projects to
    repair and modernize the basic infrastructure and institutional
    facilities at NASA centers will be conducted, as well as activities in
    support of environmental compliance and restoration requirements.
