        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

        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.
