        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 Mission
    Directorate, Exploration Systems Mission Directorate, Aeronautics
    Research Mission Directorate and the Office of Education. (Last year,
    Exploration Systems was in the Exploration Capabilities appropriation.)
    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; and other general and administrative activities supporting
    the themes within SAE.

        Detailed performance goals associated with the SAE activities are
    addressed in NASA's chapter in the 2006 Budget volume. The SAE
    activities are described below.

        Science.--NASA's Science Mission Directorate now encompass three
    themes: Earth-Sun System, Solar System Exploration, and Universe. The
    integration of the former Earth and Space Science Enterprises positions
    NASA's science endeavors to support and benefit from the President's
    vision for space exploration, while providing opportunities to maximize
    investments. The Directorate seeks to answer fundamental scientific
    questions concerning the galaxy and the universe; connections among the
    Sun, Earth and other planets of the solar system; the way in which
    Earth's climate is changing; comparisons of Earth with other planets in
    our solar system and around other stars; the origin and evolution of
    planetary systems; and the origin and distribution of life in the
    universe. The Directorate achieves its objectives

    [[Page 1074]]

    through robotic spacecraft 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
    domestic and international partners, NASA provides accurate, objective
    scientific data and analysis to advance understanding of Earth-Sun
    system processes and phenomena. NASA's contributions enable improved
    prediction and response capabilities for climate, weather, natural
    hazards, and even human-induced disasters. Employing nearly 30 Earth- or
    Sun-observing satellites that routinely make measurements with over 100
    remote sensing instruments, NASA's goal is to continue using the view
    from space to study the Earth system and improve prediction of Earth
    system changes, solar variability and the connection between the two. 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 to 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 to develop specific
    knowledge and understanding of those aspects of the Sun-Earth system
    that directly affect life and society. The Solar Terrestrial Relations
    Observatory (STEREO) will advance our understanding of the Sun's corona,
    or 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 will observe the solar interior and
    atmosphere continuously from geosynchronous orbit to determine the
    causes of solar variability. Its images will provide full-disc views of
    the sun with four times the resolution of those currently available.

        In the next few decades, NASA will deepen our 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 priceless souvenirs from other worlds. Our intensive
    investigation of Mars will continue, from above and on the surface, with
    a new generation of missions; advanced robotic missions such as the 2009
    Mars Science Laboratory are critical to the vision for space
    exploration. The past year's successful investigations of Mars and
    Saturn will be followed by spacecraft bound for the planets Mercury and
    Pluto, completing NASA's initial reconnaissance of our solar system.
    NASA will also visit the Kuiper Belt, the suspected source of comets and
    other icy bodies that lies predominantly beyond Pluto's orbit, to
    investigate the primordial substances which evolved into the solar
    system.

        To answer important scientific questions about the nature of the
    universe, 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 our ability over the
    next decade and a half to find planets around other stars and peer deep
    into the history of the universe and improve our understanding of its
    structure. The Gamma-ray Large-Area Space Telescope will investigate the
    high-energy world of black holes and neutron stars, while the Laser
    Interferometer Space Antenna will detect gravitational waves generated
    by stars and black holes throughout the universe. The Space
    Interferometry Mission (SIM) will allow indirect detection of planets
    through observation of thousands of stars and will investigate the
    structure of planetary disks. SIM will also demonstrate unprecedented
    astronomical accuracy and high spatial resolution and will serve as a
    technological precursor to the Terrestrial Planet Finder, a mission that
    will search for Earth-like planets around stars. The James Webb Space
    Telescope will study the earliest galaxies and stars formed after the
    Big Bang.

        Exploration systems.--The Exploration Systems Mission Directorate
    includes four themes that will collaboratively enable sustainable
    exploration and scientific discovery in our solar system. The themes are
    Constellation Systems, Exploration Systems Research and Technology,
    Human Systems Research and Technology, and Prometheus Nuclear Systems
    and Technology. The organization of the Mission Directorate into these
    four themes reflects, in part, the need to keep some existing
    organizational structures in place as programs are incorporated into the
    Exploration Systems Mission Directorate. This organization may change as
    implementation of the vision for space exploration progresses.

        Through the Constellation Systems theme 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 include the Crew Exploration Vehicle (CEV)
    for the transport and support of human crews traveling to destinations
    beyond low Earth orbit, as well as launch vehicles for transport of the
    CEV and cargo to LEO, and any ground support infrastructure for
    communications and operations. These systems, collectively known as the
    ``system of systems'' will be developed in a ``spiral'' approach,
    wherein early demonstrations and prototypes are used to demonstrate
    capabilities, validate technologies, and mitigate risk, all along an
    evolutionary path toward an operational capability. The planned first
    spiral development will provide the capability to deliver humans to
    orbit in a CEV by 2014. The second spiral will deliver humans to the
    lunar surface by 2020, followed by the third spiral, which will enable
    extended visits on the lunar surface. As spiral development evolves,
    system of systems elements will grow to include in-space support
    systems, destination surface systems, and additional human support
    systems.

        The Exploration Systems Research and Technology theme represents
    NASA's commitment to investing in the technologies and capabilities that
    will enable the vision for space exploration. The goals of solar system
    exploration will demand a robust, ongoing commitment to focused
    innovation that will benefit activities across the Agency. Through a
    focused research and development effort NASA will develop technologies
    planned to mature at intervals allowing pre-planned integration into
    different spirals and different missions. NASA is working closely with
    other government agencies, industry, academia, and other partners to
    leverage common requirements and identify innovative ideas. As part of
    this effort, the theme includes the Centennial Challenges program, an
    effort to establish a series of annual prizes for revolutionary,
    breakthrough accomplishments that advance solar system exploration and
    other NASA priorities. The other programs within this theme are the
    Advanced Space Technology Program, the Technology Maturation Program,
    and the Innovative Partnerships Program.

        The Human Systems Research and Technology (HSRT) theme comprises
    programs and research formerly conducted as part of NASA's Biological
    and Physical Research Enterprise. HSRT research and development is
    focused on supporting the goals associated with the vision for space
    exploration. Programs within this theme advance knowledge and technology
    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. HSRT comprises three programs: Human
    Health and Performance; Life Support and Habitation; and

    [[Page 1075]]

    Human Systems Integration. The Human Health and Performance program
    conducts research on questions about human biology and physiology
    relevant to the human exploration of the solar system, and delivers
    technology to help maintain or improve human health in the space
    environment. The Life Support and Habitation program conducts research
    and develops technology for life support and other critical systems for
    spacecraft operations. The Human Systems Integration program focuses on
    optimizing human-machine interaction in the operation of spacecraft
    systems.

        Prometheus Nuclear Systems Research and Technology is NASA's effort
    to develop nuclear power systems that can transform our ability to
    explore the solar system. Historically, space exploration has been
    limited by the power available from converting light from the Sun into
    energy. On planetary surfaces and in locations distance from the Sun,
    solar power is sometimes insufficient. Radioisotope power systems, a
    passive form of nuclear power, have addressed this issue and enabled a
    wide range of outer planetary exploration missions over the past 40
    years, as evidenced by the Galileo and Cassini spacecraft, but the power
    levels of these systems are very limited. The development of a new space
    nuclear capability can enable more sophisticated, more capable robotic
    spacecraft as well as robust systems that may be needed to support
    larger-scale operations on the surfaces of the Moon and Mars. While high
    costs and technical concerns prompted NASA to defer a nuclear-powered
    mission to study Jupiter's icy moons, the agency will start on a new
    nuclear technology demonstrator with direct applications to exploration.

        Aeronautics research.--The Aeronautics Research Mission Directorate
    seeks to provide advanced aeronautical technologies to meet the
    challenges of next generation systems in aviation for civilian and
    scientific purposes. The Directorate 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; enable more people and goods to travel faster and
    farther with fewer delays; and result in revolutionary earth and space
    science missions and opportunities for economic growth. NASA works
    closely with the Federal Aviation Administration, the Department of
    Homeland Security, industry, academia, and other governmental agencies
    in developing these technologies.

        The Aeronautics Technology Theme consists of three integrated
    programs. NASA is transforming its aeronautics program to emphasize
    development and demonstration of technologies critical to the Nation's
    future aviation requirements, in areas where NASA has unique
    capabilities. The Aviation Safety and Security Program conducts research
    and technology development for the nation's aviation system to prevent
    unintentional and intentional actions that would cause damage, harm, and
    loss of life, and to mitigate the consequences of such actions, should
    they 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 will develop the technologies and conduct flight
    demonstrations of the high risk, high payoff concepts that industry,
    with its focus on the near-term, does not fund.

        Education.--NASA works to inspire and motivate students at all
    levels to pursue careers in the fields of science, technology,
    engineering, and mathematics (STEM), 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 STEM 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.

        This appropriation provides for the full costs associated with the
    Exploration Capabilities activities of the Agency, which includes the
    Space Station, Space Shuttle, and Space and Flight Support themes within
    the Space Operations Mission Directorate. (Exploration Systems, which
    last year was in the Exploration Capabilities appropriation, has been
    moved to the Science, Aeronautics, and Exploration appropriation.) The
    full costs include both the direct and 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; and other
    general and administrative activities supporting the themes within
    Exploration Capabilities.

        Detailed performance goals associated with Exploration Capabilities
    activities are addressed in NASA's chapter in the 2006 Budget volume.
    Exploration Capabilities encompasses the following themes: International
    Space Station, Space Shuttle Program, and Space and Flight Support.

        International Space Station.--The International Space Station (ISS)
    is a complex of research laboratories in low Earth orbit in which
    American and international astronauts are conducting scientific and
    technological investigations in a micro-gravity environment. The primary
    objective of the ISS is to support the President's vision for space
    exploration. The ISS is still under construction and NASA is examining
    how best to complete it in a manner that meets the requirements of the
    vision and the ISS international partners while using as few Shuttle
    flights as possible. This reexamination is critical to fielding a space
    station that adequately supports exploration and allows the Shuttle to
    be retired in 2010 as planned.

        Space Shuttle operations are expected to begin in the late spring of
    2005 and construction of the ISS is planned to resume after the
    successful launch of two Shuttle logistics missions to the station. The
    2006 Budget request provides funding for the continuation of ISS launch
    processing activities, the resumption of vehicle on-orbit assembly with
    a crew of three, logistics re-supply and crew exchange using the Space
    Shuttle, continuation of research payload and experiment deliveries to
    orbit, and reserves sufficient to address unexpected technical issues
    that may arise as the program returns to assembly. The 2006 Budget
    request also includes funding for development of habitability
    modifications and completion of the regenerative environmental control
    and life support system needed to increase the station's crew capacity,
    consistent with human space exploration research requirements. The
    request also includes funds to initiate procurement of crew and cargo
    delivery services to support ISS logistics needs. These services are key
    to ensuring the ISS's viability both leading up to and following the
    Shuttle's retirement.

        Space Shuttle.--The Space Shuttle program's primary mission is to
    assemble the ISS. In 2010, the Space Shuttle--

    [[Page 1077]]

    after nearly 30 years of duty--will be retired from service. NASA is
    currently determining how many Shuttle flights will be required to
    complete an ISS configuration that meets the needs of both the space
    exploration vision and the international partners using as few Shuttle
    flights as possible. The 2006 Budget request assumes the Space Shuttle
    will return to flight in late spring of 2005. It provides for specific
    program investments for vehicle safety and supportability needed to
    maintain a viable Shuttle fleet through retirement. The 2006 Budget
    request will allow NASA to provide appropriate contingency resources to
    combat flight hardware obsolescence, maintain ground systems and
    facilities, and initiate early actions for an orderly phase-out of the
    program.

        Space and flight support.--The Space and Flight Support Theme
    comprises separate programs that provide ongoing customer support for
    critical NASA services including Space Communications, Launch Services,
    Rocket Propulsion Testing, and Crew Health and Safety. These services
    support a wide range of customers including NASA, other federal
    agencies, foreign governments, and commercial interests. Funds for
    environmental remediation, which were previously requested in this
    theme, are now bookkept as part of NASA's corporate general and
    administrative (G&A) funds.

        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. Those ``Mission
    Support'' activities are now budgeted as part of the full costs
    associated with projects in the Science, aeronautics, and exploration
    account or 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'', 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, [2007] 2008.
        [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 but shall
    remain available for the same period of time as originally
    appropriated.]
        From amounts made available in this Act for these activities,
    subject to [the] operating plan [procedures] notification of the House
    and Senate Committees on Appropriations, the Administrator may transfer
    amounts between the ``Science, aeronautics, and exploration'' account
    and the ``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. [Funding shall not be made available for
    Centennial Challenges unless authorized.
        Funding made available under the headings ``Exploration
    capabilities'' and ``Science, aeronautics, and exploration'' in this Act
    shall be governed by the terms and conditions specified in the statement
    of managers except to the extent changes are made in accordance with the
    operating plan procedures of the House and Senate Committees on
    Appropriations.] (Departments of Veterans Affairs and Housing and Urban
    Development, and Independent Agencies Appropriations Act, 2005.)
