    This appropriation provides for the full costs associated with the 
science, aeronautics, and exploration (SAE) activities of the agency, 
which consist of the programs, or ``themes,'' within the Science, 
Aeronautics Research, and Exploration Systems Mission Directorates and 
Cross-Agency Support Programs. Education Programs is now an element of 
Cross-Agency Support Programs. The full costs include both direct and 
indirect costs supporting these programs, which provide for all of the 
research; development; operations; salaries and related expenses; 
design, repair, rehabilitation, modification of facilities, and 
construction of new facilities; and other general and administrative 
activities supporting the themes within SAE.

    Detailed performance goals associated with the SAE activities are 
addressed in NASA's detailed budget request, and summaries of these 
activities are in the NASA chapter of the 2008 President's Budget.

    Science.--NASA's Science Mission Directorate encompasses four 
themes: Earth Science; Planetary Science; Heliophysics; and 
Astrophysics. The Directorate seeks to answer fundamental questions 
concerning: the ways in which Earth's climate is changing; the 
comparison of Earth with other planets in the solar system and around 
other stars; the connections among the Sun, Earth, and heliosphere; and 
the origin and evolution of planetary systems, the galaxy, and the 
universe, including the origin and distribution of life in the universe. 
The Directorate achieves its objectives through robotic flight missions, 
ground-based scientific research and data analysis, and the development 
of new technologies for future missions.

    Life on Earth prospers in a biosphere and climate powered by energy 
from the Sun and moderated by water and carbon cycles. Working with the 
domestic and international partners,

[[Page 986]]

NASA provides accurate, objective, scientific data and analysis to 
advance understanding of Earth system processes and phenomena, thus 
improving prediction and response capabilities for climate, weather, 
natural hazards, and even human-induced disasters. Employing a 
constellation of 15 Earth-observing satellites routinely making 
measurements, NASA continues using the view from space to study the 
Earth system and improve prediction of Earth system changes and the 
connection between Earth and its star, the Sun.

    In the next few decades, NASA will increase understanding of the 
solar system, with spacecraft fanning out to destinations from the 
innermost planet to the very edge of our Sun's influence. Some will stay 
in Earth's orbit; others will follow looping one-way trajectories 
through the gravitational forces of the planets, and a few will come 
back carrying mystery-unlocking souvenirs from other worlds. Our 
intensive investigation of Mars will continue, from orbit and on the 
surface, with a new generation of missions, including the 2009 Mars 
Science Laboratory rover (September 2009 launch, June 2010 arrival).

    The Dawn mission is planned for launch in 2007 on a nine-year 
mission to investigate in detail 1 Ceres and 4 Vesta, two main-belt 
asteroids that are among the largest proto-planets remaining intact 
since the formation of the solar system. The Cassini Saturn orbiter will 
continue to return stunning images and revise our understanding of the 
ringed planet and its moons. Meanwhile, the Messenger mission to Mercury 
and the New Horizons mission to Pluto will complete NASA's initial 
reconnaissance of the solar system. NASA will also study the Kuiper Belt 
and the comets that come from it to investigate the primordial 
substances that evolved into the solar system.

    In seeking to understand the Sun, heliosphere, and planetary 
environments as a single, connected system, NASA will pursue two sets of 
missions: Solar Terrestrial Probe missions address fundamental science 
questions about the physics of plasma and the flow of mass and energy in 
the solar system, and Living With a Star missions develop specific 
knowledge and understanding of those aspects of the Sun-Earth system 
that directly affect life and society. The Solar Terrestrial Relations 
Observatory, launched in October 2006, will advance understanding of the 
Sun's corona, or its outer ``atmosphere,'' and the origin of huge 
eruptions of solar material known as coronal mass ejections. Under 
Living With a Star, the Solar Dynamics Observatory, to be launched in 
August 2008, will observe the solar interior and atmosphere continuously 
from geosynchronous orbit to determine the causes of solar variability. 
Its images will provide global views of the Sun with four times the 
resolution of those currently available.

    Within the Astrophysics theme, perplexing and important questions 
guide our quest to understand the secrets of the universe:

    How did the universe begin?

    Does time have a beginning and an end?

    Where did we come from?

    Are we alone?

    To answer these questions, NASA will continue to operate its 
prolific Hubble, Chandra, and Spitzer space telescopes, while planning a 
series of future missions linked by powerful new technologies and 
complementary approaches to shared science goals. These missions will 
enhance NASA's ability to find planets around other stars and peer deep 
into the history of the universe and improve understanding of its 
structure. The Kepler mission will enable the discovery of Earth-size 
and smaller planets around other stars. The Gamma-ray Large-Area Space 
Telescope will investigate the high-energy world of black holes and 
neutron stars. The James Webb Space Telescope will study the earliest 
galaxies and some of the first stars formed after the Big Bang.

    Exploration Systems.--The Exploration Systems Mission Directorate 
(ESMD) includes two themes that work together to enable sustainable 
exploration and scientific discovery in our solar system: Constellation 
Systems and Advanced Capabilities.

    The Constellation Systems theme is responsible for developing 
capabilities essential to making the Nation's Vision for Space 
Exploration a reality. Through Constellation Systems, NASA will develop, 
demonstrate, and deploy the transportation, life support, and surface 
systems that will enable sustained human and robotic exploration of the 
Moon, Mars, and beyond. These systems include the Orion Crew Exploration 
Vehicle that will transport and support crews traveling beyond low Earth 
orbit, launch vehicles for transporting Orion and cargo into space, and 
ground support infrastructure for communications and operations. 
Constellation Systems activity supports NASA's mission to explore the 
universe, search for life, and extend human presence to the Moon, Mars, 
and beyond. A human presence will enable scientific activities and 
discoveries not obtainable with robotic explorers.

    ESMD was established to achieve the goals laid out by the President 
in his January 2004 speech, and will do so based on the architecture and 
vehicle systems outlined in the 2005 Exploration Systems Architecture 
Study. Further analysis and refinement of the study's results has 
continued under the direction of ESMD. Initial Constellation Systems 
capabilities include Orion, the crew exploration vehicle; Ares, the crew 
launch vehicle; Extravehicular Activity suits and tools required by the 
flight crews; and associated ground and mission operations 
infrastructure. These systems are intended to support exploration, but 
in their initial test phases will support low Earth orbit missions 
including crew transportation to the International Space Station. The 
Orion also will be capable of delivering some cargo to the Space 
Station, although current plans are to provide servicing via commercial 
systems.

    An important element of Constellation Systems is the International 
Space Station commercial crew/cargo services project, also known as 
Commercial Orbital Transportation Services (COTS). The Vision for Space 
Exploration called for NASA to pursue commercial opportunities for 
providing transportation to the International Space Station. The 
Commercial Orbital Transportation Services project is intended to spur 
private industry to provide cost-effective cargo delivery to the 
International Space Station, allowing NASA to focus its internal 
resources on exploration.

    Following the initial capabilities, Constellation Systems will 
develop crew capabilities for a lunar surface mission by 2020. These 
capabilities include the Ares V heavy-lift launch vehicle, leveraging 
engineering design and capabilities from the Shuttle Program; an Earth 
Departure Stage to propel Orion from low Earth to lunar orbit; a Lunar 
Surface Access Module to safely transport astronauts to and from the 
lunar surface; and systems, capabilities, and support for extended human 
stays on the lunar surface. Future development will provide crew, cargo 
transportation, and destination support capabilities required for human 
exploration of Mars and beyond.

    The Advanced Capabilities theme consists of three programs: the 
Lunar Precursor Robotic Program, the Exploration Technology Development 
Program, and the Human Research Program. Activities within these 
programs help prepare for human lunar exploration, test new technologies 
that enable exploration, and further understanding of the effects of 
space on human performance.

    The Lunar Precursor Robotic Program develops precursor missions to 
characterize the lunar environment. The first of these will be the Lunar 
Reconnaissance Orbiter, which is scheduled to launch in October 2008. 
The Exploration Tech

[[Page 987]]

nology Development Program makes focused investments in innovations to 
reduce the cost and expand the capabilities of future space exploration 
missions. The Human Research Program focuses on ensuring the health, 
safety, and productivity of humans embarking on missions of exploration 
in our solar system. Projects advance knowledge critical for supporting 
long-term human survival and performance during operations beyond low 
Earth orbit, with a focus on improving medical care and human health 
maintenance.

    Aeronautics research.--The Aeronautics Research Mission Directorate 
conducts high-quality, innovative research to expand the boundaries of 
aeronautical knowledge for the benefit of the broad aeronautics 
community, which includes NASA's partners in academia, industry, and 
other Government agencies.

    NASA has significantly restructured its aeronautics program to 
ensure meaningful and relevant research that is aligned with national 
priorities. The program conducts high-quality, cutting-edge research 
that will lead to revolutionary concepts, technologies, and capabilities 
that enable radical change to both the airspace system and the aircraft 
that fly within it, facilitating a safer, more environmentally friendly, 
and more efficient air transportation system. At the same time, NASA is 
ensuring that aeronautics research and critical core competencies 
continue to play a vital role in support of the Vision for Space 
Exploration. NASA will continue to advance knowledge and capabilities in 
aeronautical disciplines such as aerothermodynamics, flight dynamics and 
control, materials and structures (including advanced thermal protection 
systems), and integrated vehicle health management.

    NASA's Aeronautics theme consists of three integrated research 
programs as well as the Aeronautics Test Program that preserves a 
critical suite of aeronautics test facilities.

    The Fundamental Aeronautics Program will conduct cutting-edge 
research that will enable the design of vehicles that fly through any 
atmosphere at any speed. Because aircraft of the future will need to 
address multiple and often conflicting design challenges such as noise, 
emissions, and performance, a key focus will be the development of 
physics-based, multidisciplinary design, analysis, and optimization 
tools. Such tools will make it possible to evaluate radically new 
vehicle designs and to assess, with known uncertainties, the potential 
impact of innovative concepts and technologies on a vehicle's overall 
performance.

    The Aviation Safety Program builds upon the unique safety-related 
research capabilities of NASA to develop tools, methods, and 
technologies that will improve the intrinsic safety attributes of 
current and future aircraft, and to overcome aircraft safety 
technological barriers that would otherwise constrain the full 
realization of the Next Generation Air Transportation System.

    The Airspace Systems Program conducts cutting-edge air traffic 
management research that will enable the Next Generation Air 
Transportation System. In partnership with the Joint Planning and 
Development Office, the program will help develop the concepts, 
capabilities, and technologies that will lead to significant 
enhancements in capacity, efficiency, and flexibility needed to meet the 
Nation's airspace and airportal requirements (gates, taxiways, runways, 
and final approach airspace) for decades to come.

    The Aeronautics Test Program ensures the strategic availability and 
accessibility of a critical suite of aeronautics test facilities that 
are deemed necessary to meet aeronautics, Agency, and national needs. 
Strategic utilization, operations, maintenance, and investment decisions 
are made for major wind tunnel/ground test facilities at NASA's Ames 
Research Center, Glenn Research Center, and Langley Research Center, and 
for the Western Aeronautical Test Range, support aircraft, and test bed 
aircraft at Dryden Flight Research Center.

    Cross-Agency Support Programs.--Cross-Agency Support Programs 
includes four single-program themes that encompass several ongoing 
activities and improve NASA's approach to managing unique facilities. 
The themes are Education, Advanced Business Systems, Innovative 
Partnerships Program, and Shared Capability Assets Program.

    NASA's Education Program works to inspire and motivate students at 
all levels to pursue careers in the fields of science, technology, 
engineering, and mathematics, while also engaging the education 
community to reach this goal. NASA's objectives include providing 
elementary and secondary students and teachers with NASA-related 
education opportunities; supporting higher education research capability 
and opportunities that attract and prepare students and faculty for 
NASA-related careers; providing students, teachers, faculty, and 
researchers from underrepresented and underserved communities with 
opportunities in NASA-related science and technology fields; and 
increasing student, teacher, and public access to NASA education 
resources by developing and deploying innovative technology applications 
platforms. NASA engages the public in shaping and sharing the experience 
of exploration and discovery by improving public understanding of 
science and technology, including NASA aerospace technology, research, 
and exploration missions.

    The Integrated Enterprise Management Program became part of the new 
Advanced Business Systems theme in 2006. The program also became a 
direct-funded program rather than being funded through Corporate and 
Center General and Administrative accounts. The program was established 
in 2000 with an objective to modernize and integrate NASA's business 
systems and processes and is replacing Center-unique and/or Directorate-
unique approaches with a single set of standard integrated business 
processes. New systems are improving NASA business practices by 
minimizing data redundancy, standardizing information and electronic 
data exchanges, processing and recording financial events effectively 
and efficiently, and ensuring consistent information is available for 
decision makers.

    The program consists of functional projects that are formulated 
following the approval of a business case. Each project is charged with 
implementing appropriate information technology tools to meet specific 
sets of business requirements. To date, the following projects have been 
implemented by the program: Resume Management; Position Description 
Management; Travel Management; Core Financials; Program Management 
Information Improvement; Agency Labor Distribution System; Recruitment 
One Stop; e-Payroll; SAP Version Update; and Contract Management Module. 
The following projects are currently in formulation or development: 
Aircraft Management; Integrated Asset Management; Human Capital 
Information Environment; and e-Travel.

    NASA's Innovative Partnerships Program is focused on adding value to 
NASA through partnerships. The mission of the program is to provide 
leveraged technology alternatives for NASA's mission directorates, 
programs, and projects through joint partnerships with industry, 
academia, Government agencies, and national laboratories. Products 
include leveraged technology investments, dual-use technology-related 
partnerships, and secured intellectual property assets. Partnerships 
serve to increase the range of technology solutions for NASA, enable 
cost avoidance, and accelerate technology maturation. The program 
consists of the following elements: Technology Infusion, which includes 
the Small Business Innovative Research/Small Business Technology 
Transfer Program and the Innovative Partnerships Program Seed Fund; 
Innovation Incubator, which includes Centennial Challenges and new 
efforts to facilitate purchase of services from the emerging commercial 
space sector; and Partnership Development, which includes Intellectual 
Property Management, Technology Transfer, and new innovative 
partnerships. Together these

[[Page 988]]

increase NASA's connection to emerging technologies in the external 
communities, enable targeted positioning of NASA's technology portfolio 
in selected areas, and secure NASA's intellectual property to provide 
fair access and to support NASA's strategic goals. Dual-use partnerships 
and licensing also create socio-economic benefits within the broader 
community.

    NASA established a Shared Capability Assets Program, a corporately 
managed program, to ensure that its key capabilities and assets will 
continue to be available to support the missions that require them. 
Additionally, NASA will use this new program to identify and prioritize 
its critical assets and make strategic investment decisions to replace, 
modify, or disposition them based on NASA and/or national needs. NASA's 
Real Property Management Plan, which is approved by the Office of 
Management and Budget, supports NASA's goal of preserving key 
capabilities and assets that are critical to NASA's current and future 
missions.

    NASA has identified seven specific key capability/assets to 
implement NASA's missions. These capability/assets are wind tunnels, 
flight operations and test infrastructure, rocket propulsion testing, 
High End Computing Columbia, thermal vacuum chambers, simulators, and 
arc jets. While funding for four of these capability/assets is in the 
mission directorates (Aeronautics: wind tunnels and flight operations 
and test infrastructure, Space Operations: rocket propulsion testing, 
and Science: High End Computing Columbia), all these capability/assets 
are managed and integrated by the Shared Capability Assets Program. 
Additional capability/assets may be added to the Shared Capability 
Assets Program in future years through a nomination, review, and 
selection process by the Agency.

    This appropriation provides for the full costs associated with the 
Exploration Capabilities activities of the Agency, which include the 
Space Shuttle, International Space Station, and Space and Flight Support 
programs, or themes, which are managed by the Space Operations Mission 
Directorate. The full costs include both direct and indirect costs 
supporting these programs and provide for all of the research; 
development; operations; salaries and related expenses; design, repair, 
rehabilitation, modification of facilities, and construction of new 
facilities; and other general and administrative activities supporting 
the themes within Exploration Capabilities.

    Detailed performance goals associated with the Exploration 
Capabilities activities are addressed in NASA's detailed budget request, 
and summaries of these activities are included in the NASA chapter of 
the 2008 President's Budget.

    The Space Shuttle program's mission will complete the assembly of 
the International Space Station as planned by the end of the decade. In 
addition, the 2008 Budget supports one servicing mission to the Hubble 
Space Telescope. It provides for specific program investments for 
vehicle safety and supportability needed to maintain a viable Shuttle 
fleet through the end of the decade. The 2008 Budget request will allow 
NASA to provide appropriate contingency resources to combat flight 
hardware obsolescence, maintain ground systems and facilities, and 
continue the orderly phase-out of the program. In addition, the Shuttle 
program will support the Space Operations and Exploration Systems 
Mission Directorates in integrating selected Shuttle flight hardware and 
ground systems to advance the development of the Orion crew exploration 
vehicle and the Ares I and V launch vehicles.

    The International Space Station is a complex of research 
laboratories in low Earth orbit in which American, Russian, Canadian, 
European, and Japanese astronauts are conducting unique scientific and 
technological investigations in a micro-gravity environment. The 
objective of the Space Station is to support scientific and engineering 
research for human space exploration. Development is complete on all 
U.S. flight elements required to finish assembly by the end of the 
decade. The on-orbit assembly of the Space Station is about 55 percent 
complete. In 2006, the resumption of Space Shuttle flights returned the 
Space Station to assembly activities. The 2008 Budget provides funding 
for Space Station launch processing activities, maintenance of a crew of 
three on board, continuation of vehicle on-orbit assembly including 
construction of the truss and power segments and the addition of the 
international partner modules, and continuation of research payload and 
experiment deliveries to orbit. It also includes funding for development 
of habitability modifications, purchase of additional spares to be 
stowed on the Space Station for use during the post-Shuttle period, 
purchase of cargo and crew services from international partners, and the 
development of the ExPRESS Logistics Carrier to transport and stow 
critical Space Station components and spares on orbit.

    Space and Flight Support is comprised of separate programs that 
provide ongoing customer support for a wide range of services including 
Space Communications, Launch Services, Rocket Propulsion Testing, and 
Crew Health and Safety. These services are critical to the conduct of 
space exploration, science and aeronautical research, and physiological 
research. They are provided to a wide range of customers including NASA, 
other Federal agencies, foreign governments, and commercial interests. 
Space Communications is procuring two satellites to maintain and 
continue service using the aging Tracking and Data Relay Satellite 
System network. These two replacement satellites will meet user demand 
through 2016.

                        Administrative Provisions

     Notwithstanding the limitation on the availability of funds 
appropriated for ``Science, Aeronautics and Exploration'', or 
``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'', or 
``Exploration Capabilities'' by this appropriations Act, the amounts 
appropriated for construction of facilities shall remain available until 
September 30, 2010.
     Funds for announced prizes otherwise authorized shall remain 
available, without fiscal year limitation, until the prize is claimed or 
the offer is withdrawn.
     The balances of prior appropriations to the National Aeronautics 
and Space Administration 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 shall be merged with funds in the newly established account 
and thereafter may be accounted for as one fund under the same terms and 
conditions but shall remain available for the same period of time as 
originally appropriated.
     Amounts made available in this Act under the headings, ``Science, 
Exploration, and Aeronautics'' and ``Exploration Capabilities'' may be 
transferred between such accounts, subject to the reprogramming 
procedures in section 605 of this Act.
