    This appropriation provides for the full costs associated with the 
Exploration, Science and Aeronautics (ESA) 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 Exploration, Science and 
Aeronautics programs.

    Detailed performance goals associated with the Exploration, Science 
and Aeronautics activities are addressed in NASA's FY 2005 Integrated 
Budget and Performance Document.

    Space science.--NASA's Space Science Enterprise 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 Enterprise achieves its objectives 
through flight missions (e.g. robotic spacecraft), ground-based 
scientific research and data analysis, and the development of new 
technologies for future missions.

    More than 30 Space Science spacecraft will be operating during FY 
2005. These include astronomical telescopes, such as the Hubble Space 
Telescope, the Chandra X-Ray Observatory and the Spitzer Space 
Telescope; interplanetary spacecraft to Mercury, Mars, Saturn, and 
comets; and missions studying the Sun and its influence on Earth. 
Research based on data from these missions will revolutionize our 
understanding of the universe and our place in it, while continuing to 
capture the imagination of the public, and especially schoolchildren.

    In addition to Mars Exploration, which is augmented in this budget, 
NASA will be working on a wide variety of exciting, previously approved 
programs for launch after FY 2005. For example, the New Horizons mission 
to Pluto and beyond will complete NASA's initial reconnaissance of the 
solar systems. The Solar Terrestrial Relations Observatory (STEREO) will 
advance understanding of the Sun's corona (its outer ``atmosphere'') and 
the origin of huge eruptions of solar material known as coronal mass 
ejections. The Gamma-ray Large-Area Space Telescope (GLAST) will 
investigate the high-energy world of black holes and neutron stars. And 
in the next decade, the James Webb Space Telescope, the Laser 
Interferometer Space Antenna, the Jupiter Icy Moons Orbiter, a new 
generation of Mars missions, and others will provide unprecedented 
potential for discovery.

    Earth science.--NASA's Earth Science Enterprise contributes to the 
Agency's mission to understand and protect our home planet by using our 
view from space to study the Earth system and improve prediction of 
Earth system change. The Earth Science Enterprise seeks to answer a 
question of funda

[[Page 1044]]

mental importance to science and society: How is the Earth system 
changing, and what are the consequences for life on Earth? In pursuit of 
answers to 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 18 Earth observing satellites 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, NASA has defined two 
strategic objectives corresponding with our two budget themes, Earth 
System Science and Earth Science Applications: (1) observe, analyze, and 
model the Earth system to discover how it is changing and the 
consequences for life on Earth; and (2) expand and accelerate the 
realization of economic and societal benefits from Earth science 
information and technology.

    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. NASA uses the global view from space to contribute to the 
U.S. Government's Climate Change Science and Technology Programs. We 
have identified key areas of investment that will enable us to reduce 
the scientific 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 is used to address a variety of national 
priorities, including economic issues and homeland security. Through the 
Earth Science Applications theme, 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 Enterprise (BPRE) addresses the opportunities and challenges of 
space flight through basic and applied research on the ground and in 
space aboard the International Space Station. In concert with the new 
exploration vision, NASA will refocus BPRE research on activities that 
prepare human explorers to travel beyond low Earth orbit, such as the 
development of countermeasures against space radiation and the long-term 
effects of reduced gravity. BPRE consists of 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 of nature. The theme supports 
NASA's mission to explore the universe and search for life both through 
applied research to improve safety and efficiency of human space flight 
and through exploratory research on the fundamental laws of nature.

    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 conducts 
fundamental biological research as an integral element of understanding 
how space affects life. This theme also supports research to identify, 
characterize, and control the physiological and psychological challenges 
to human health associated with human space flight and space 
exploration, including risks associated with exposure to radiation, 
microgravity, and prolonged individual and group isolation. The theme 
also includes research and development to improve the reliability and 
performance of life support systems and interactions between the crew 
and the spacecraft systems.

    The FY 2005 budget reflects the priorities of the new national 
vision for space exploration. The budget expands planned biomedical 
research and countermeasures experiments, including the Human Research 
Initiative and links all research to the Enterprise's strategic goals.

    Aeronautics.--The Aeronautics Enterprise addresses three of NASA's 
goals through the Aeronautics Technology theme. To achieve the goal of 
``enabling a safer, more secure, efficient, and environmentally friendly 
air transportation system'', the theme conducts research and develops 
enabling technology that will: reduce 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 in developing these technologies. 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 Homeland Security, 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 NASA's goal to ``enable 
revolutionary capabilities through new technology.''

    Aeronautics Technology consists of three integrated programs. The 
Aviation Safety and Security Program directly addresses the safety and 
security research & technology development needs of the nation's 
aviation system to either prevent both unintentional and intentional 
actions that would cause damage, harm, and loss of life or mitigate the 
consequences when these types of situations occur. The Airspace Systems 
Program conducts research and technology development that will enable 
revolutionary improvements to, and modernization of, the National 
Airspace System, as well as the introduction of new systems for vehicles 
whose operation can take advantage of the improved, modern air traffic 
management system. The Vehicle Systems Program develops enabling 
technologies that will produce future vehicles that are environmentally 
friendly, quieter, faster, more efficient, and technologically superior 
and/or support science missions and commercial applications requiring 
high altitude, long endurance, and remote operations.

    Education.--The Education Enterprise plays the leading role in 
NASA's mission to inspire the next generation of explorers. From the 
excitement of the launch countdown to awe-inspiring images of planets 
and galaxies, aeronautics and space exploration can ignite imaginations 
young and old. The journey to space, however, does not start at the 
launch pad--it starts in the classroom. The NASA mission--to understand, 
explore, and inspire--depends upon people with the ingenuity to invent 
new tools, the passion to solve problems, and the courage to ask 
difficult questions. Inspiring the next generation of scientists, 
technologists, engineers, and educators

[[Page 1045]]

means engaging the education community and inviting them to participate 
in our ongoing work and process of discovery.

    To this end, the Education Enterprise works to inspire and motivate 
students at all levels to pursue careers in the fields of science, 
technology, engineering, and mathematics (STEM), as well as teaching. 
The Enterprise partners with academic institutions, professional 
education associations, industry, and other Government agencies to 
provide teachers and faculty with the experiences that capitalize on the 
excitement of NASA's discoveries to spark their students' interest and 
involvement. The Enterprise provides students with opportunities for 
involvement in NASA's vast research efforts to promote the STEM 
disciplines and encourage them to pursue higher education at the 
graduate and doctoral levels. Finally, The Enterprise engages the public 
in the experiences of exploration and discovery.

    NASA's strategy to accomplish its goals in education involves the 
achievement of four objectives: (1) Increase the number of elementary 
and secondary students and teachers who are involved in NASA-related 
education opportunities; (2) support higher education research 
capability and opportunities that attract and prepare increasing numbers 
of students and faculty for NASA-related careers; (3) increase the 
number and diversity of students, teachers, faculty, and researchers 
from underrepresented and underserved communities in NASA-related STEM 
fields; and (4) increase student, teacher, and public access to NASA 
education resources via the establishment of e-Education as a principal 
learning support system. NASA engages the public in the experience of 
exploration and discovery by improving public understanding of science 
and technology, including NASA aerospace technology, research, and 
exploration missions.

    This appropriation provides for the full costs associated with the 
capabilities that support Agency research, which consist of the 
Exploration Systems and Space Flight Enterprises. 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 Exploration Capabilities programs.

    Detailed performance goals associated with the Exploration 
Capabilities activities are addressed in NASA's FY 2005 Integrated 
Budget and Performance Document. The Exploration Capabilities activities 
include Space Flight and Exploration Systems, 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, and international astronauts are conducting 
unique scientific and technological investigations in a micro-gravity 
environment. The objectives of the ISS program are to support on-orbit 
scientific research and other activities that require human 
participation. In concert with the new exploration vision, NASA will 
refocus U.S. Space Station research on activities that prepare human 
explorers to travel beyond low Earth orbit, such as the development of 
countermeasures against space radiation and the long-term effects of 
reduced gravity. Over the past two years, the program has re-established 
cost control credibility and is positioned to address enhancements 
needed to expand ISS research capabilities. Flight hardware required to 
support the launch of all assembly elements has been delivered to the 
launch site and is undergoing integrated test and acceptance. The 
Columbia accident delayed completion of ISS assembly and introduced 
additional cost risk to the program. The FY 2005 Budget provides funding 
for the completion of ground development activities, resumption of 
vehicle on-orbit assembly with a crew of three, logistics re-supply and 
crew exchange using the Space Shuttle, resumption of research payload 
and experiment deliveries to orbit, and reserves sufficient to address 
Columbia-related impacts. Prior to the accident, sixteen U.S. assembly 
and logistic missions were successfully completed. Completion of the 
U.S. Core configuration is expected to occur 17 to 18 months after 
Shuttle return to flight.

    The Space Shuttle has served as the centerpiece of the Nation's 
human space flight program for more than 20 years. This vehicle is the 
workhorse for Space Station assembly and remains instrumental for the 
laboratory's completion. Consequently, NASA will return the Shuttle to 
service to complete the Space Station, doing so with safety as its top 
priority and based on the Columbia Accident Investigation Board's 
recommendations. But because the aging system remains costly to operate, 
lacks some safety capabilities that could be incorporated into future 
systems, and lacks the capability to fly beyond low Earth orbit, NASA 
plans to retire the Shuttle at the end of this decade, once its role in 
Space Station assembly is complete. The FY 2005 budget 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 programs that provide on-
going customer support for a wide range of services including 
environmental activities, space communications, Launch Services, and 
rocket propulsion systems testing. These services are provided to a wide 
range of customers including NASA, other Federal agencies, foreign 
governments and commercial interests.

    Exploration systems.--The Exploration Systems Enterprise includes 
three new themes that will function cooperatively to enable sustainable 
exploration and scientific discovery in the solar system. The themes are 
Lunar Exploration, Human and Robotic Technology, and Transportation 
Systems. The themes in the new Exploration Systems Enterprise 
incorporate three themes that were formerly in the Aerospace Technology 
Enterprise: Space Launch Initiative, Mission and Science Measurement, 
and Innovative Technology Transfer Partnerships.

    The Lunar Exploration (LE) theme will define requirements for a 
planetary surface exploration architecture that will be tested on the 
lunar surface, assigning functions to humans and robots based on their 
respective capabilities and characteristics. The specific number, 
frequency, duration, sizes and types of human lunar missions and systems 
will be determined based on which capabilities require demonstration at 
the moon, operational concepts for future human and robotic Mars 
exploration, and research results from ongoing Mars robotic missions. 
The Lunar Exploration Theme will develop and conduct robotic missions 
beginning in 2008 to test system capabilities, gather engineering data 
for future systems development, identify resources, and characterize the 
operating environment at the lunar surface. These precursor missions 
will lay a foundation for human missions to the Moon in the next decade 
that will demonstrate how humans and robots work together as integrated 
elements of the architecture that will be used to explore Mars and other 
destinations in the years to come. These human and robotic missions to 
the moon will also seek to address lunar science priorities.

    The Human and Robotic Technology (HRT) theme represents NASA's 
commitment to investing in the technologies and capabilities that will 
make the national vision for space exploration possible. Through applied 
technology research, focused technology maturation, and timely 
technology transition, the HRT theme will develop technologies that can 
be integrated into missions in the LE theme and applied by other NASA's 
enterprises. Working with NASA and non-NASA researchers and 
technologists, through directed investments and innovative partnerships, 
the HRT theme will advance a range of high-leverage technologies and 
space operations concepts, mature and validate key technologies, and 
transition them into applications to enable safe, affordable and 
sustainable human and robotic exploration of the solar system. The HRT 
theme will work closely with other government agencies, industry, 
academia and potential international partners to leverage common 
requirements and identify innovative ideas. The HRT theme incorporates 
activities and funds from the former Mission and Science Measurement 
theme and the former Innovative Technology Transfer Partnerships theme, 
including the Small Business Innovative Research (SBIR) and Small 
Business Technology Transfer Research (STTR) programs.

    The Transportation Systems (TS) theme will provide crew transfer 
capabilities as an integral element of a developing architecture to 
support exploration missions to the Moon,

[[Page 1047]]

Mars and beyond. The activities of the TS theme will be focused on the 
objective of developing and demonstrating a vehicle to provide crew 
transportation for missions beyond low Earth orbit. NASA will conduct 
the initial test flight of this vehicle before the end of this decade in 
order to provide an operational capability to support human exploration 
missions beyond low Earth orbit no later than 2014. The TS theme 
incorporates remaining funds from the former Space Launch Initiative 
theme.

    NASA's ``Human Space Flight'' account included the International 
Space Station; Payload and ELV Support; Human Exploration and 
Development of Space Investments and Support; Space Communications and 
Data Systems; and Safety, Mission Assurance and Engineering). In FY 
2004, these activities--except for Safety, Mission Assurance and

    NASA's ``Mission Support'' account included Research and Program 
Management 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 Exploration, Science and Aeronautics 
account or the Exploration Capabilities account (except for 
environmental activities, which had previously been included in CoF, and 
is now budgeted separately under Exploration Capabilities). This account 
shows spending from balances prior to the account restructuring.

    From 1995 to 2003, CoF activities were included in Human Space 
Flight; Science, Aeronautics and Technology; and Mission Support. 
Beginning in 2004, NASA's CoF activities were performed in the Science, 
Aeronautics and Exploration or Enabling Capabilities accounts. Beginning 
in FY 2005, the Science, Aeronautics and Exploration account has been 
renamed the ``Exploration, Science and Aeronautics'' account and the 
``Space Flight Capabilities'' account has been renamed the ``Exploration 
Capabilities'' account. This account shows spending from balances prior 
to the account restructuring.

                        Administrative Provisions

    Notwithstanding the limitation on the availability of funds 
appropriated for [``Science, aeronautics and exploration''] 
``Exploration, science, and aeronautics'', or [``Space Exploration 
flight capabilities''] ``Exploration capabilities'' by this 
appropriations Act, when any activity has been initiated by the 
incurrence of obligations for construction of facilities or 
environmental compliance and restoration activities as authorized by 
law, such amount available for such activity 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''] 
``Exploration, science, and aeronautics'', or [``Space flight] 
``Exploration capabilities'' by this appropriations Act, the amounts 
appropriated for construction of facilities shall remain available until 
September 30, [2006] 2007.
    From amounts made available in this Act for these activities, the 
Administration may transfer amounts between [aeronautics of] the 
[``Science, aeronautics and exploration''] ``Exploration, science, and 
aeronautics'' account and [crosscutting technologies of] the [``Space 
flight] ``Exploration 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. (Division 
G, H.R. 2673, Consolidated Appropriations Bill, FY 2004.)
