    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 goal of 
the Station is to support activities requiring the unique attributes of 
humans in space and establish a permanent human presence in Earth orbit. 
The proposed budget provides multi-year funding through an advanced 
appropriation for the complete development of the Station with Station 
assembly beginning in mid-1998 and finishing by the end of 2003. With 
the first launch to assemble this unique orbital laboratory only a few 
months away, the budget includes sufficient funding to keep subsequent 
assembly missions on schedule and provide a long-term solution to the 
safe return of the full complement of Station crewmembers.

    In 1997, node and laboratory module fabrication were completed, the 
node was delivered to the launch site, and qualification testing of 
flight hardware components continued. Activities are well underway to 
support crew training, payload processing, and hardware element 
processing requirements. In 1998, continued fabrication of flight 
hardware, qualification testing, and assembly and integration will be 
the focus of the program. First element launch is scheduled for the 
summer of 1998. In 1999, plans are to complete phase 2 (the first ten 
assembly flights) of the Station.

    U.S./Russian Cooperation and Program Assurance.--As part of an 
operating plan approved in May 1997, the U.S./Russian budget line was 
discontinued, and a new budget line entitled U.S./Russian Cooperation 
and Program Assurance was established. It includes two activities, U.S./
Russian Cooperation and Russian Program Assurance (RPA). U.S./Rus-

[[Page 986]]

sian Cooperation continues the support to the Russian Space Agency, 
including the cooperative use of Mir. The RPA budget was established to 
implement contingency plans in response to the slippage of the Russian 
service module (SM) to the Space Station, from May 1998 to December 
1998. The United States and Russia are continuing a program of joint 
space missions. In 1997, three Shuttle flights to Mir took place, 
highlighted by the continual presence of American astronauts 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 (ISS). Two 
additional flights are planned in FY 1998, completing phase I of this 
cooperative precursor to Space Station.

    The RPA provides contingency planning funds to address ISS program 
requirements resulting from delays on the part of Russia in meeting its 
commitments to the ISS program. The first step in the contingency plan 
is to protect against a potential further delay in the SM. The ISS 
program is purchasing, from the U.S. Naval Research Laboratory (NRL), an 
interim control module (ICM) to provide attitude control and reboost 
functions for continuation of the ISS assembly sequence in case the 
Russian SM is launched later than December 1998. The NRL's ICM will be 
prepared for a February 1999 launch and will be attached to the back of 
the Russian built functional cargo block (FGB). If the SM is launched in 
December 1998, the ICM will be reconfigured to be attached to the SM. 
The ICM would then be able to dock to the back of the SM in 1999 to back 
up any shortfall of Russian Progress fuel resupply vehicles.

    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, 3 module missions (MSL-1 reflight and Neurolab) will be 
flown, along with 2 pallet missions. The Spacelab program is scheduled 
to be terminated in 1998, following the Neurolab mission. In FY 1999, 
one (Spacelab) science mission will be supported, in addition to seven 
assembly flights for the ISS.

    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 1998, over 20 major and 
secondary payloads will be supported; in FY 1999, a similar number will 
be supported, including major hardware for ISS assembly. Advanced 
Projects 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 ISS. Beginning in FY 1999, 
funding for Advanced Projects other than X-38 and X-38 transition costs, 
will be terminated. 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 partially 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 FY 1998, six missions are planned, 
including the final two flights to the Russian Mir Space Station, and 
the initial assembly flight for the ISS. 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 1999, eight shuttle flights are planned, seven of which are in 
support of ISS assembly. Upgrades to the shuttle to increase its 
reliability and maintainability will be continued. Major Shuttle 
upgrades, including the Super Light Weight Tank and the Alternate Turbo 
Pump, will be completed with initial flights planned to occur in 1998.

    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.

    Funding for Space Science, Earth Science, Aeronautics and Space 
Transportation Technology is proposed as part of the Research Fund for 
America. This proposal highlights the Administration's priority to 
providing needed and sustained investments in important Federal research 
programs on a deficit neutral basis. A discussion of the Research Fund 
for America, and two other funds for the environment and transportation, 
can be found in Section II of the Budget volume.

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 1997, highlights included the July 4 landing 
of the Pathfinder spacecraft on Mars, the first Mars landing since the 
Viking missions in 1976 and the first ever to use air bags to cushion 
impact on the surface. Shortly after Pathfinder's landing, the Sojourner 
rover began its own exploration of nearby rocks and other features. The 
images from both craft were posted to the Internet, where more than 500 
million ``hits'' were recorded by the end of July. The international 
Cassini mission left Earth bound for Saturn on October 15, 1997. With 
the European Space Agency's Huygens probe and a high-gain antenna 
provided by the Italian Space Agency, Cassini will arrive at Saturn July 
1, 2004. Also, astronauts flawlessly performed major maintenance and 
upgrades to the orbiting Hubble Space Telescope, replacing older 
hardware with two dramatically improved instruments that are helping 
astronomers probe the universe in greater detail than ever before. This 
year, Hubble uncovered over 1,000 bright, young star clusters bursting 
to life in a brief, intense, brilliant ``fireworks show'' at the heart 
of a nearby pair of colliding galaxies. The Hubble image of the galactic 
collision was printed on the front pages of newspapers around the world 
as well as on the cover of Newsweek magazine. Images captured during 
Galileo's closest flyby of Europa on February 20 showed features of the 
Jovian moon, lending credence to the possibility of hidden, subsurface 
oceans. The findings generated new questions about the possibility of 
life on Europa. Scientists using the joint European Space Agency/NASA 
Solar and Heliospheric Observatory (SOHO) spacecraft have discovered 
``jet streams'' or ``rivers'' of hot, electrically charged plasma 
flowing beneath the surface of the sun. These new findings will help 
scientists understand the famous 11-year sunspot cycle and associated 
increases in solar activity that can disrupt the Earth's power and 
communications systems.

    To capitalize on these enormous successes during the past year, the 
NASA budget request for FY 1999 once again highlights Space Science. 
Space Science continues to focus on the Origins program and fundamental 
questions regarding the creation of the universe and planetary systems 
and the possibility of life beyond Earth. In addition to planning for 
the deployment of powerful telescopes to detect Earth-like planets 
elsewhere in our galaxy, planning has begun for a Europa mission to 
launch in 2003 to directly observe potential subsurface oceans on 
Europa, and the Mars Surveyor Program is augmented to enhance the Mars 
2001 lander. NASA will also initiate a series of Solar-Terrestrial 
Probes to track solar phenomena and their impact on the Earth, and 
initiate mission development for a gamma-ray telescope to understand the 
final stages of stars' lives and to seek out the most extreme 
environments in the universe.

    Development activities will continue in 1998-1999 on the Advance X-
ray Astrophysics Facility (AXAF) in support of a launch in early FY 
1999. Development activities continue on the Relativity (Gravity Probe-
B) mission, which remains on schedule for launch in 2000. The Space 
Infrared Telescope Facility (SIRTF) initiates development in April 1998, 
with launch planned for December 2001. Development activities on the 
Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) 
mission began in 1997, with launch planned in 2000. Development 
activities on the Stratospheric Observatory for Infrared Astronomy 
(SOFIA) continue to receive support. The Second Hubble Space Telescope 
(HST) servicing mission in February 1997 provided two new science 
instruments and other servicing, and the upgraded telescope is providing 
new insights into our universe by investigating objects in the near-
infrared portion of the electromagnetic spectrum. Funding for HST 
continues to support operations, as well as preparation for the third 
servicing mission in 1999. Galileo's highly successful tour of Jupiter 
and its moons has

[[Page 988]]

been extended through 1999, with a focus on the moons Europa and Io.

    In Explorer missions, the Advanced Composition Explorer (ACE) was 
launched in August 1997 and development activities continue on the Far 
Ultraviolet Spectroscopy Explorer (FUSE) for a launch in 1998. 
Development is also underway for the Microwave Anisotropy Probe (MAP) 
and Imager for Magnetosphere-to-Aurora Global Exploration (IMAGE) 
Medium-Class Explorer (MIDEX) missions. Three new Small (SMEX) missions 
were selected in 1997: the High Energy Spectroscopic Imager (HESSI) is 
to launch in 2000; the Galaxy Evolution Explorer (GALEX) will launch in 
2001; the Two Wide-Angle Neutral-Atom Spectrometers (TWINS) has been 
selected as a mission of opportunity, to be launched in 2001 or 2003 
aboard a currently undesignated U.S. Government mission. These missions 
emphasize reduced mission costs and accelerated launch schedules.

    The Mars Global Surveyor entered Mars orbit in September 1997, and 
funds are requested for the development of future Mars missions in 1998 
and beyond. The third Discovery-class mission, Lunar Prospector, 
launched in January 1998, the fourth, the Stardust mission, is to be 
launched in 1999. Two new Discovery missions were selected in 1997: the 
Comet Nucleus Tour (CONTOUR) to be launched in 2002; and Genesis, a 
solar wind sample return mission, to be launched in 2001. The New 
Millenium program is underway to provide flight demonstrations of 
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-1 and Deep Space-2 missions, scheduled for launch in July 
1998 and January 1999, respectively.

    The Space Science program is responsible for Agency-wide core 
technology development. 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 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 addition 
to conducting basic and applied research, this program provides the 
opportunity to refine the definition, design, and development of 
experiment hardware planned for use on the ISS. In FY 1998 five Shuttle 
missions involving Life and Microgravity Science are planned, including 
the USMP-4 mission and Neurolab, the final Spacelab series flight. The 
final two NASA/Mir missions are planned for 1998. The NASA/NIH Neurolab 
mission 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 FY 1999, as 
assembly of the ISS continues, the program will fly one science mission 
(STS-95) on a Spacelab carrier with ISS precursor science experiments. 
The U.S. Laboratory will be launched for ISS mid-year, which will allow 
Life and Microgravity hardware and experiments to be established aboard 
the ISS and will begin a new era of research.

    Earth Science.--The purpose of NASA's Earth Science (ES) enterprise 
is to understand the total Earth system and the effects of natural and 
human-induced changes on the global environment. ES 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, ES is providing the scientific foundation 
needed for the complex policy choices that lie ahead on the road to 
sustainable development. ES 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 ES science and technology in 
the public and private sectors.

    The Earth Observing System (EOS), the centerpiece of Earth Science, 
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 spectrometer 
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, provided 10 months of ocean winds data. The failure of 
Japan's ADEOS satellite meant the loss of the NASA scatterometer (as 
well as one of the two TOMS). NASA will launch QUIKSCAT in November 1998 
to minimize the loss of ocean winds data. In 1997 the Tropical Rainfall 
Measuring Mission (TRMM) began measuring tropical precipitation. 
Complementing EOS will be a series of small, rapid development Earth 
System Science Pathfinders (ESSP). Data from ES 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. The ES science program is essential to 
the discovery of new concepts and to the design of future missions. The 
ES 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 long-term high risk, high payoff technologies 
that are effectively transferred to industry and government. This 
Enterprise has developed dramatic technology goals which are grouped 
into three areas: global civil aviation, revolutionary technology leaps, 
and access to space. These technology goals reflect the national 
priorities for aeronautics and space.

    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

[[Page 989]]

jobs for the United States. In FY 1997, a two-dimensional bifurcated 
inlet concept and a center-stick flight controller concept were selected 
for further research and evaluation. In FY 1999, funding is included to 
extend High-Speed Research to mitigate risk in two critical areas--
propulsion and airframe materials and structures. In FY 1997, the 
Advanced Subsonic Technology program completed the set of National 
Airspace System operational scenarios in support of aviation capacity 
research. In FY 1998, the Aging Aircraft element will be completed with 
the field demonstrations on nondestructive evaluation prototypes that 
can locate cracks, corrosion and disbonds in aircraft fuselages. Funding 
is included to continue development of high payoff technologies that 
enable a safe, highly productive global air transportation system with 
reduced environmental impact.

    The High Performance Computing and Communications program 
demonstrated significant reductions in cost and time in performing 
three-dimensional aerodynamic simulations that reduced the development 
time for an extremely fuel-efficient, high pressure compressor by 50%. 
In FY 1998, this program's NASA Research & Education Network (NREN) 
begins activities supporting development of the Next Generation Internet 
(NGI) to increase quality, security and certainty of Internet 
transmissions on a network capable of 1,000 times the capacity of the 
1996 baseline. This initiative will involve several Federal agencies, 
including the Departments of Defense, Energy and Commerce, the National 
Science Foundation, and NASA. In FY 1997, research activities within the 
research and technology base developed innovative concepts, explored new 
areas of theory and created the computational models of the aeronautical 
principles that lead to more efficient design and operation of advanced 
aerospace systems. In FY 1998, the safety research will be initiated in 
support of the Administration's Aviation Safety initiative and in FY 
1999, the research and technology base will continue to develop advanced 
concepts and technologies that will allow safe, economical and 
environmentally compatible air transportation systems.

    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 the safety and reliability of current and future generation 
launch systems. In 1997, the Reusable Launch Vehicle (RLV) program 
continued to pursue technology development, design and business planning 
activities in support of next-generation reusable systems, on the X-33 
and X-34 flight demonstrators. The X-33 and X-34 have completed their 
critical design reviews and initiated fabrication of flight hardware. 
Funding for the RLV program in 1998 and 1999 is included to continue X-
33 and X-34 technology development, hardware fabrication and test, in 
preparation for the flight of the technology demonstrators, both of 
which will fly in 1999. 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 on developing technology required to 
support NASA strategic needs that are not currently addressed by RLV. 
Industry-led Future Space Launch trade studies in 1999 and 2000 will 
support an end-of-the-decade decision called for in the National Space 
Transportation Policy on the development of an operational launch system 
to reduce NASA's launch costs. $760 million in placeholder funds are set 
aside in the outyears to pursue existing, planned or new vehicles in 
response to this decision.

    The Commercial Technology Program's focus in FY 1997 has been to 
invest 10-15 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 and expand 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.

    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 
1997-1999, 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. Development of a remote ground terminal at Guam which will extend 
network capability by providing for coverage of the zone of exclusion 
will be completed in FY 1998. Development of the replenishment Tracking 
and Data Relay satellites is ongoing. The first satellite will be 
launched in late FY 1999. The NASA Integrated Services Network 
consolidated all NASA wide area network systems in FY 1997.

    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 1997-1999, 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.

                        Administrative Provisions

    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 
any activity has been initiated by the incurrence of obligations for 
construction of facilities as authorized by law, 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, [2000] 2001.
     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, [1998] 1999 
and may be used to enter into contracts for training, investigations, 
costs associated with personnel relocation, and for other services, to 
be provided during the next fiscal year.
    [Of the funds provided to the National Aeronautics and Space 
Administration in this Act, the Administrator shall by November 1, 1998, 
make available no less than $400,000 for a study by the National 
Research Council, with an interim report to be completed by June 1, 
1998, that evaluates, in terms of the potential impact on the Space 
Station's assembly schedule, budget, and capabilities, the engineering 
challenges posed by extravehicular activity (EVA) requirements, United 
States and non-United States space launch requirements, the potential 
need to upgrade or replace equipment and components after assembly 
complete, and the requirement to decommission and disassemble the 
facility.]
    NASA shall develop a revised appropriation structure for submission 
in the Fiscal Year 2000 budget request consisting of two basic 
appropriations (the Human Space Flight Appropriation and the Science, 
Aeronautics and Technology Appropriation) with a separate (third) 
appropriation for the Office of the Inspector General. The 
appropriations shall each include the planned full costs (direct and 
indirect costs) of NASA's related activities and allow NASA to shift 
civil service salaries, benefits and support between and/or among 
appropriations or accounts, as required, for the safe, timely, and 
successful accomplishment of NASA missions. (Departments of Veterans 
Affairs and Housing and Urban Development, and Independent Agencies 
Appropriations Act, 1998.)
