    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.

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.

    Notwithstanding the limitation on the availability of funds 
appropriated for ``Human space flight'', ``Science, aeronautics and 
technology'', or ``Mission support'' by this appropriations Act, when 
[(1)] any activity has been initiated by the incurrence of obligations 
for construction of facilities as authorized by law, [or (2) amounts are 
provided for full-funding for the Tracking and Data Relay Satellite 
(TDRS) replenishment program,] such amount available for such activity 
shall remain available until expended. This provision does not apply to 
the amounts appropriated in ``Mission support'' pursuant to the 
authorization for repair, rehabilitation and modification of facilities, 
minor construction of new facilities and additions to existing 
facilities, and facility planning and design.
    Notwithstanding the limitation on the availability of funds 
appropriated for ``Human space flight'', ``Science, aeronautics and 
technology'', or ``Mission support'' by this appropriations Act, the 
amounts appropriated for construction of facilities shall remain 
available until September 30, [1999] 2000.
    Notwithstanding the limitation on the availability of funds 
appropriated for ``Mission support'' and ``Office of Inspector 
General'', amounts made available by this Act for personnel and related 
costs and travel expenses of the National Aeronautics and Space 
Administration shall remain available until September 30, [1997] 1998 
and may be used to enter into contracts for training, investigations, 
cost associated with personnel relocation, and for other services, to be 
provided during the next fiscal year.
    [Upon the determination by the Administrator that such action is 
necesssary, the Administrator may, with the approval of the Office of 
Management and Budget, transfer not to exceed $177,000,000 of funds made 
available in this Act to the National Aeronautics and Space 
Administration for the International Space Station between ``Science, 
aeronautics and technology'' and ``Human space flight'', to be merged 
with and to be available for the same purposes, and for the same time 
period, as the appropriation to which transferred: Provided, That such 
authority may not be used unless for higher priority items than those 
for which originally appropriated: Provided further, That the 
Administrator of the National Aeronautics and Space Administration shall 
notify the Congress promptly of all transfers made pursuant to this 
authority.] (Departments of Veterans Affairs and Housing and Urban 
Development, and Independent Agencies Appropriations Act, 1997.)
