    This appropriation provides for the full costs associated with the 
Science, Aeronautics and Exploration (SAE) activities of the Agency, 
which consist of the Space Science, Earth Science, Biological and 
Physical Research, Aeronautics, and Education Programs. The full costs 
include both the direct and the indirect costs supporting these 
programs, and provide for all of the research; development; operations; 
salaries and related expenses; design, repair, rehabilitation, and 
modification of facilities and construction of new facilities; 
maintenance and operation of existing facilities; and other general and 
administrative activities supporting Science, Aeronautics and 
Exploration programs. This account includes activities that were 
previously funded in the Science, Aeronautics, and Technology account.

Performance Objectives

    Detailed performance goals associated with the Science, Aeronautics 
and Exploration (SAE) activities are addressed in NASA's FY 2004 
President's Budget. The SAE activities include: Space Science, Earth 
Science, Biological and Physical Research, Aeronautics, and Education 
Programs; and are described below.

    Space Science.--NASA's Space Science program seeks to answer 
fundamental questions concerning: the galaxy and the universe; the 
connections among 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.

    NASA will proceed in the development of several major missions, 
including the Stratospheric Observatory for Infrared Astronomy (SOFIA), 
the Solar Terrestrial Relations Observatory (STEREO), the Gamma-ray 
Large-Area Space Telescope (GLAST), the Solar Dynamics Observatory (SDO) 
and the final Hubble Space Telescope (HST) Servicing Mission. SOFIA 
development will continue in preparation for a spring 2005 first science 
flight. STEREO, scheduled for launch in November 2005, will advance our 
understanding of the Sun's corona (its outer ``atmosphere''), the origin 
of huge eruptions of solar material known as coronal mass ejections 
(CMEs), and the interaction between CMEs and the Earth's environment. 
GLAST, which will investigate the high-energy world of black holes and 
neutron stars, is on track for launch in the fall of 2006. SDO will 
increase our understanding of the Sun's magnetic field, solar wind, 
energetic particles, and variations in solar irradiance. Development of 
SDO begins in 2004. During the final HST Servicing Mission, also 
scheduled for 2004, astronauts will install the Cosmic Origins 
Spectrograph (COS) and Wide Field Camera 3 (WFC3) to extend the 
telescope's operational life to 2010. Development activities supporting 
several key missions in the payloads program, such as Solar-B and 
Herschel, will also continue in 2004.

[[Page 956]]

    Support for the Explorer and New Millennium programs will continue. 
Small- and Medium-class Explorer missions provide frequent flight 
opportunities for a diverse array of world-class scientific 
investigations--recently selected projects will examine diffuse 
intergalactic radiation and ice in Earth's mesosphere. Another Small 
Explorers mission, the second of the Two Wide-angle Imaging Neutral-atom 
Spectrometers (TWINS), will be launched in 2004 to provide stereoscopic 
images of the Earth's magnetosphere for the first time. The New 
Millennium Program provides 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. Several of these innovative Space Technology projects (ST-
5, 6, and 7) are scheduled for launch from 2004 through 2006.

    The Discovery Program provides frequent access to space for small 
planetary missions that will perform high-quality scientific 
investigations. Both Deep Impact, the first space mission to probe 
beneath the surface of a comet and reveal the secrets of its interior, 
and the Mercury Surface, Space Environment, Geochemistry and Ranging 
(MESSENGER) mission to orbit Mercury are scheduled for launch in 2004. 
The Kepler Mission to explore the structure and diversity of planetary 
systems, with a special emphasis on detecting Earth-size planets in the 
habitable zones around other stars, will be in development in 2004, as 
will the Dawn mission to study the asteroids 1 Ceres and 4 Vesta.

    Focused technology programs are included in each of the five major 
Space Science themes: Astronomical Search for Origins, Structure and 
Evolution of the Universe, Solar System Exploration, Mars Exploration 
Program, and Sun-Earth Connection. Funding is provided for early 
technology development in support of strategic missions, such as the 
James Webb (formerly ``Next Generation'') Space Telescope and the Living 
With a Star Program. The goal is to retire technology risk early in a 
mission's lifecycle, before proceeding to full-scale development. Funds 
are also provided to continue ongoing operations of approximately thirty 
spacecraft, and to conduct robust research and analysis, data analysis, 
and suborbital research campaigns.

    The budget request for 2004 features two new initiatives: Optical 
Communication and the Jupiter Icy Moons Tour. Optical Communication 
seeks to use lasers to improve by many orders of magnitude the 
communication data rate for deep space missions. Current limitations on 
data transfer using radio constrain scientific discovery and public 
participation in our space missions. The Jupiter Icy Moons Tour will 
explore the icy moons of Jupiter (Europa, Ganymede, and Callisto), 
providing a full characterization of the moons through orbital 
reconnaissance. This will set the stage for the next phase of Jovian 
exploration, to include surface chemical and organic investigations, and 
a probe to explore the sub-surface environment. This mission will be 
part of Project Prometheus, an effort started last year to demonstrate 
nuclear power and nuclear electric propulsion technology that can open 
the solar system to detailed research and exploration.

    Earth Science.--NASA's Earth Science Program contributes to the 
Agency's mission to understand and protect our home planet by developing 
a scientific understanding of the Earth system and its response to both 
natural and human-induced changes to enable improved prediction of 
climate, weather and natural hazards for present and future generations.

    The Earth Science Program 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? In pursuit of this 
question, NASA has pioneered 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. Employing a constellation of over 15 Earth observing 
satellites routinely making measurements with over 80 remote sensing 
instruments, NASA has made it an Agency goal to understand the Earth 
system and apply Earth System Science to improve prediction of climate, 
weather, and natural hazards. Within this goal, we have defined two 
strategic objectives: (1) Science--observe, analyze, and model the Earth 
system to discover how it is changing and the consequences for life on 
Earth; and (2) Applications--expand and accelerate the realization of 
economic and societal benefits from Earth science information and 
technology; with Earth System Science and Earth Science Applications as 
the corresponding budget themes.

    Within Earth System Science, NASA works with the science community 
to identify questions on the frontiers of science that have profound 
societal importance, and to which remote sensing of the Earth can make a 
defining contribution. These science questions become the foundation of 
a research strategy, which defines requirements for scientific 
observations, and a roadmap for combining the technology, observations, 
modeling efforts, basic research, and partnerships needed to answer the 
questions over time. We are responding to the scientific community's 
call for comprehensive observation of the Earth's major components using 
the Earth Observing System (EOS). NASA uses the global view from space 
to contribute to the U.S. Government's Global Change Research Program 
(USGCRP) and Climate Change Research Initiative (CCRI). We have 
identified key areas of investment that will enable us to do more, and 
do it more rapidly, with a targeted investment in observations, 
research, and modeling of uncertainties surrounding the forces acting on 
the climate system.

    Within Earth Science Applications, NASA enables the application of 
information and knowledge gained through partnerships with other federal 
agencies. These partnerships focus on innovative approaches for using 
Earth science information and knowledge to provide decision support 
information. This information supports myriad operational applications, 
as well as policy discussions, and is used to address a variety of 
national priorities, including economic issues and homeland security. 
Through the Earth Science Applications program, NASA is working with 
organizations with the appropriate information infrastructure to apply 
NASA's Earth science results to help manage coastal environments, 
agriculture and water resources, and aviation safety; monitor air and 
water quality, forest fires, and the impacts of infectious diseases and 
invasive species; and conduct hurricane forecasting and disaster relief 
efforts. The potential socioeconomic benefits of these applications are 
significant.

    Biological and Physical Research.--NASA's Biological and Physical 
Research (BPR) Enterprise addresses the opportunities and challenges of 
space flight through basic and applied research on the ground and in 
space. The program exploits the rich opportunities of space flight in 
pursuit of answers to a broad set of scientific questions that support 
NASA's goals to explore the fundamental principles of physics, chemistry 
and biology through research in the unique natural laboratory of space, 
and to extend the duration and boundaries of human space flight to 
create new opportunities for scientific exploration and discovery. The 
major outcomes of this research include fundamental scientific progress 
and safer more efficient space travel. BPR includes three themes: 
Biological Sciences Research, Physical Sciences Research, and Research 
Partnerships and Flight Support.

    Physical Science Research supports basic and applied research that 
takes advantage of the unique environment of space to expand our 
understanding of the fundamental laws

[[Page 957]]

of nature. The theme supports NASA's mission to explore the universe and 
search for life both through applied research to improve safety and 
performance and through exploratory research on the fundamental laws of 
nature. The theme supports NASA's mission to understand and protect our 
home planet by producing research results that have direct application 
to industrial products and processes.

    Biological Science Research conducts basic and applied research to 
enable and support a safe human presence in space in support of NASA's 
mission to explore the universe and search for life. This theme includes 
a basic biology research component that pursues fundamental biological 
research questions as an integral element of understanding how space 
affects life at all levels, from genes to cells to organisms. This theme 
supports research to define and control the physiological and 
psychological challenges to human health associated with space flight, 
including research on radiation risks, risks associated with 
microgravity, and risks associated with prolonged isolation and small 
group dynamics. The theme also includes research and development to 
improve the reliability and performance of life support systems and 
spacecraft crew interfaces.

    The FY 2004 budget request reflects the results of the NASA Advisory 
Council's Research Maximization and Prioritization (ReMaP) Task Force 
recommendations. The request expands planned biomedical research and 
countermeasures experiments, including a new Human Research Initiative; 
initiates a limited flight program in high priority advanced human 
support technology; places additional emphasis on physical science 
research, including applications to human space flight; and reinstates 
funding for plant and animal habitats for planned centrifuge research on 
the International Space Station (ISS).

    Implementing ReMaP in the FY 2004 budget is a crucial first step in 
a longer running planning and prioritization process. In the near term, 
research and facility development are aligned with the ReMaP priorities 
in the FY 04 Budget. At the same time, BPR has responded to NASA's new 
strategic plan by adopting a 5-year direction consistent with overall 
agency vision, mission and goals. This direction has identified major 
research thrusts, consistent with the agency strategic plan and the 
management changes required to support these thrusts.

    Aeronautics.--Aeronautics Technology addresses the Agency's goal to 
``enable a safer, more secure, efficient, and environmentally friendly 
air transportation system'' by performing research and technology to: 
decrease the aircraft fatal accident rate and the vulnerability of the 
air transportation system to threats; protect the local and global 
environmental quality by reducing aircraft noise and emissions; and 
enable more people and goods to travel faster and farther with fewer 
delays. NASA works closely with the Federal Aviation Administration 
(FAA) in setting these goals. Additionally, in support of the Agency 
goal ``to create a more secure world and improve the quality of life by 
investing in technologies and to collaborate with other agencies, 
industry and academia,'' Aeronautics Technology supports national 
security through aeronautical partnerships with the Department of 
Defense and other government agencies. Finally, this theme enables 
pioneering aeronautical concepts to support earth and space science 
missions and new commercial markets in support of the Agency goal to 
``enable revolutionary capabilities through new technology.''

    Three research and technology programs compose the Aeronautics 
Technology theme. The Aviation Safety and Security Program develops and 
demonstrates technologies and strategies for the prevention, 
intervention, and mitigation of factors contributing to aviation 
accidents. This theme gives highest priority to the factors that are 
most strongly tied to accident and fatality rates, as well as those that 
address multiple classes of hazards, including hazardous weather, 
controlled flight into terrain, accidents and incidents caused by human 
error, and mechanical or software malfunctions. The program develops and 
integrates technologies needed to build a safer aviation system, to 
support pilots and air traffic controllers, and to provide information 
to assess situations and trends that might indicate unsafe conditions 
before accidents occur. NASA develops, validates and transfers these 
advanced concepts, technologies and procedures through a partnership 
with the Federal Aviation Administration (FAA) and in cooperation with 
the U.S. aeronautics industry.

    To enable increased capacity and mobility of the nation's air 
transportation system, the Airspace Systems program develops and 
demonstrates technology for revolutionary improvements to, and 
modernization of, the air traffic management (ATM) system. The 
technology enables new ATM decision support tools and airspace concepts 
as well as new systems for aircraft whose operation can take advantage 
of the improved, modern ATM system. The resultant benefit to the 
traveling public will be reduced flight delays and shorter doorstep-to-
destination times. Users of the technologies that result from this 
program include: the FAA, state and local airport authorities and their 
systems suppliers, existing and new commercial and personal aviation 
operators, and the aircraft developers and their system suppliers. This 
program directly supports the FAA's ``Free Flight'' activities and the 
Operational Evolution Plan (OEP) and maintains pace with a continually 
evolving technical environment.

    The Vehicle Systems program develops breakthrough technologies to 
enable new capability and functionality in future aircraft. Technologies 
from this program are then further developed in the Aviation Safety and 
Security Program and the Airspace Systems program to reduce aircraft 
emissions and noise, enable more people and goods to travel faster and 
farther, and to increase air system safety and security. The Vehicle 
Systems program also supports development of common advanced air vehicle 
technologies with the DOD.

    Education.--Since its establishment, NASA has served the Nation's 
educational interests by sharing its unique mission, facilities, 
personnel, and research results with inquisitive minds throughout the 
United States and around the globe. The results have opened the minds of 
people of all ages, races and background to the universe, new 
technologies and expanded possibilities. As the 21st century begins, and 
new national challenges are before us, it is appropriate that NASA re-
examine and re-energize the Agency's education mission and organization. 
To that end, a NASA Education Office has been established as a new, 
mission-focused organization that will aggregate NASA's education 
programs, management and staff. This Office will position NASA to more 
effectively leverage its resources to encourage student interest in 
math, science, and technology education--to inspire the next generation 
of explorers, as only NASA can.

    The NASA Education Office will work toward achieving four 
priorities: (1) motivating K-16+ students to pursue careers in science, 
math and engineering; (2) providing educators with unique teaching tools 
and compelling teaching experiences; (3) seeking to ensure that we are 
investing the taxpayer's resources wisely; and (4) engaging minority and 
underrepresented students, educators and researchers in NASA's education 
program. An important and visible component of the NASA Education Office 
is the Minority University Research and Education Program, insuring that 
minority education programs are a high priority for the Agency.

    This appropriation provides for the full costs associated with the 
capabilities that support Agency research, which consist of the Space 
Flight and Crosscutting Technology Programs. The full costs include both 
the direct and the indirect costs supporting these programs, and provide 
for all of the research; development; operations; salaries and related 
expenses; design, repair, rehabilitation, and modification of facilities 
and construction of new facilities; maintenance and operation of 
existing facilities; and other general and administrative activities 
supporting Science, Aeronautics and Exploration programs. This account 
includes activities that were previously funded in the Human Space 
Flight and Science, Aeronautics, and Technology accounts.

Performance Objectives

    Detailed performance goals associated with the Enabling Capabilities 
activities are addressed in NASA's FY 2004 President's Budget. The 
Enabling Capabilities activities include Space Flight and Crosscutting 
Technology, and are described below.

    Space Flight.--Space Flight encompasses the following themes: 
International Space Station (ISS), Space Shuttle Program, and Space and 
Flight Support.

    The ISS is a complex of research laboratories in low Earth orbit 
(LEO) in which American, Russian, Canadian, European, and Japanese 
astronauts are conducting unique scientific and technological 
investigations in a micro-gravity environment. The objectives of the 
Station are to support scientific research and other activities 
requiring the unique attributes of humans in space, and establish a 
permanent

[[Page 959]]

human presence in Earth orbit. Program estimates have been determined to 
be credible by independent assessment teams, however, concerns were 
raised in regard to the sufficiency of funding levels to cover risks to 
program performance and to expand research. To this end, the FY 2004 
Budget request provides increased funding for continued development of 
the vehicle and for operations in support of continued assembly, 
logistics re-supply, crew exchange, research operations and other 
utilization. With fourteen U.S. assembly and logistic 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, and to continue to expand 
research opportunities commensurate with the build-up of on-orbit 
utilization capabilities and resources.

    The Space Shuttle Program plays a vital role in NASA's strategic 
goal to advance human exploration, use, and development of space by 
providing safe, routine access to space in support of permanent human 
operations in Low Earth Orbit. NASA planning assumes the Space Shuttle 
will need to be capable of supporting assembly and operation of the 
Space Station for at least this decade. Specific program investments are 
required in order to maintain this human transport capability through 
this decade. These investments are consistent with NASA's strategy of 
ensuring the Space Shuttle remains viable until a new transportation 
system is operational. The FY 2004 budget request will allow NASA to 
meet the intended flight rates, provide appropriate contingency planning 
to assure transportation and assembly support to the ISS program and 
include high priority projects for safety and supportability. These 
projects will combat obsolescence of vehicles, ground systems, and 
facilities, in order to maintain the program's safety and viability 
through this decade.

    Space and Flight Support is comprised of separate ``enabling 
capabilities'' programs that provide on-going customer support for a 
wide range of services including environmental activities, space 
communications, Space Shuttle payloads processing, expendable launch 
vehicles, and rocket propulsion systems testing. These services are 
critical for the conduct of space exploration, aeronautical research and 
physiological research. They are provided to a wide range of customers 
including NASA, other U.S. federal agencies, foreign governments and 
commercial interests. Space and Flight Support also includes the 
Advanced Systems program, which will enable NASA to take a ``stepping 
stone'' approach to future NASA missions through by advanced research 
and technology development.

    Crosscutting Technology.--The Aerospace Technology Enterprise 
includes three themes in Crosscutting Technology: Space Launch 
Initiative, Mission & Science Measurement Technology, and Innovative 
Technology Partnerships.

    The Space Launch Initiative (SLI) will develop the Orbital Space 
Plan (OSP) to help assure safe, affordable, and reliable U.S.-based crew 
access and return from the Space Station. The OSP will start as a crew 
return vehicle, launched on an Evolved Expendable Launch Vehicle (EELV). 
Initially, the OSP will provide crew return capability by 2010. By 2012, 
the Orbital Space Plane will evolve to be flown on a human-rated EELV 
and will transfer crew, and possibly limited cargo, to and from the 
International Space Station. This capability will serve as a complement 
and backup to the Space Shuttle for taking crew into space. Later, the 
Orbital Space Plane could become the basis for a crew transfer vehicle 
on a new reusable launch vehicle. Funds for the OSP will support an 
aggressive effort to assess options and complete a preliminary design by 
2005. If the Orbital Space Plane is approved for full-scale development, 
the program will be managed in a streamlined approach to reduce the cost 
of development and maintain an aggressive schedule. The Next Generation 
Launch Technology (NGLT) program will be responsible for making the 
investments relating to the next SLI goal, that focuses on making future 
space transportation systems safer, more affordable, and more reliable. 
NASA will make focused, strategic investments in key technology areas--
including propulsion, structures and operations--to be applied to both 
reusable and expendable launch systems. The NGLT program will enable 
future development decisions on launch systems that support NASA's space 
transportation needs for the upcoming decades.

    The Mission and Science Measurement Technology (MSM) theme enables 
revolutionary capabilities through new technology. MSM objectives are to 
develop science-driven architectures and technology, to create knowledge 
from scientific data, and to develop capabilities for assessing and 
managing mission risk. The advanced system concepts, fundamental 
technologies, and engineering tools developed by MSM are unique to NASA 
needs, and are applicable across many classes of missions in multiple 
Enterprises. These products may require many years to progress from 
initial concept definition to mission infusion. Three programs have been 
formulated to accomplish MSM objectives: the Computing, Information, and 
Communications Technologies (CICT) Program, that develops breakthrough 
information and communication systems to increase our understanding of 
scientific data and phenomena; the Engineering for Complex Systems (ECS) 
Program, that develops the capabilities to assess and manage risk in the 
synthesis of complex systems; and the Enabling Concepts and Technologies 
(ECT) Program, that defines new system concepts, and develops new 
technologies to enable new science measurements for the NASA 
Enterprises.

    NASA's Innovative Technology Partnership activities consist of: 
Commercial Programs, Technology Transfer agents, the Enterprise Engine, 
and the Small Business Research programs. In FY 2004, NASA will initiate 
an orderly phase- out of the existing Commercial Technology Program, and 
a new concept--the Enterprise Engine--will be introduced. The Enterprise 
Engine will create partnerships between NASA, industrial firms and the 
venture capital community to address NASA's new technology mission needs 
through innovative technology development partnerships. NASA's Small 
Business Research programs will continue. They include the Small 
Business Innovation Research (SBIR) and the Small Business Technology 
Transfer (STTR) programs, which were created by Congress, and promote 
awards of NASA research contracts to the small business community and 
promote commercialization of the products of this research by the small 
business community. These programs help NASA develop innovative 
technologies by providing competitive research contracts to U.S. owned 
small businesses.

    NASA's ``Mission Support'' account included Research and Program 
Management (R&PM) and Construction of Facilities (CoF), which have not 
been included in a separate appropriation since 2001. Instead, those 
``Mission Support'' activities are budgeted as part of the full costs 
associated with projects in the Science, Aeronautics and Exploration 
account or the Enabling Capabilities account (except for environmental 
activities, which had previously been included in CoF, and is now 
budgeted separately under Enabling Capabilities). This account shows 
spending from balances prior to the account restructuring.

    Beginning in 2004, NASA's Construction of Facilities (CoF) 
activities will be performed in the Science, Aeronautics and Exploration 
or Enabling Capabilities accounts. From 1995 to 2003, CoF facilities 
activities were included in Human Space Flight; Science, Aeronautics and 
Technology; and Mission Support. This account shows spending from 
balances prior to the account restructuring.

    For necessary expenses of the Office of Inspector General in 
carrying out the Inspector General Act of 1978, as amended, $26,300,000.

    Note.--A regular 2003 appropriation for this account had not been 
enacted at the time the budget was prepared; therefore, this account is 
operating under a continuing resolution (P.L. 107-229, as amended). The 
amounts included for 2003 in this budget reflect the Administration's 
2003 policy proposals.

shall remain available until expended. This provision does not apply to 
the amounts appropriated for institutional minor revitalization and 
construction of facilities, and institutional facility planning and 
design.
    Notwithstanding the limitation on the availability of funds 
appropriated for ``Science, aeronautics and exploration'', or ``Space 
flight capabilities'' by this appropriations Act, the amounts 
appropriated for construction of facilities shall remain available until 
September 30, 2006.
    From amounts made available in this Act for these activities, the 
Administration may transfer amounts between aeronautics of the 
``Science, Aeronautics and Exploration'' account and crosscutting 
technologies of the ``Space flight capabilities'' account.
    Funds for announced prizes otherwise authorized shall remain 
available, without fiscal year limitation, until the prize is claimed or 
the offer is withdrawn.
    The unexpired balances of prior appropriations to NASA for 
activities for which funds are provided under this Act may be 
transferred to the new account established for the appropriation that 
provides such activity under this Act. Balances so transferred may be 
merged with funds in the newly established account and thereafter may be 
accounted for as one fund under the same terms and conditions.
