    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, 
Exploration Systems, and Aeronautics Research 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 2007 Budget volume. The SAE 
activities are described below.

    Science.--NASA's Science Mission Directorate encompasses three 
themes: Earth-Sun System, Solar System Exploration, and Universe. The 
Directorate seeks to answer fundamental questions concerning the galaxy 
and the universe; the connections among the Sun, Earth and heliosphere; 
the ways in which Earth's climate is changing; the comparison 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 through flight missions (e.g. robotic spacecraft), 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, NASA provides accurate, objective, 
scientific data and analysis to advance understanding of Earth-Sun 
system processes and phenomena. This enables improved prediction and re

[[Page 1066]]

sponse capabilities for climate, weather, natural hazards, and even 
human-induced disasters. Employing a constellation of about 30 Earth or 
Sun observing satellites routinely making measurements with about 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 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 (STEREO) will advance our understanding of the Sun's corona 
(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 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.

    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 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 Phoenix lander 
(August 2007 launch) and the 2009 Mars Science Laboratory rover.

    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 our solar 
system. We will also study the Kuiper Belt, and the comets that come 
from it, to investigate the primordial substances which evolved into the 
solar system.

    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 our ability to find planets around other stars and peer deep 
into the history of the universe and improve our 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 (GLAST) will investigate the high-energy world of black holes 
and neutron stars. 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. 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 three themes that work together to enable sustainable 
exploration and scientific discovery in our solar system. The themes are 
Constellation Systems, Exploration Systems Research and Technology, and 
Human Systems Research and Technology.

    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 (LEO), as well as launch vehicles for transport 
of the CEV and cargo to LEO, and any ground support infrastructure for 
communications and operations.

    The Constellation Systems theme is responsible for developing 
capabilities essential to making the nation's Vision for Space 
Exploration a reality. Constellation Systems supports NASA's mission to 
explore the universe and search for life by developing the 
transportation and supporting systems to extend human presence to the 
Moon, Mars, and beyond. A human presence will enable scientific 
activities and discoveries not obtainable with robotic explorers.

    The program is established to achieve the goals laid out by the 
President in his January 2004 speech, and will do so by developing the 
architecture and vehicle systems outlined in the 2005 Exploration 
Systems Architecture Study (ESAS). Further analysis and refinement of 
the ESAS results will continue under the direction of the ESMD. Initial 
Constellation Systems capabilities include the CEV, Crew Launch Vehicle 
(CLV), 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 (LEO) missions including crew 
transportation to the International Space Station (ISS). The CEV will 
also be capable of delivering some cargo to the ISS, although this will 
be a backup to commercial systems.

    An important element of Constellation Systems is the commercial 
crew/cargo project. The Vision for Space Exploration called for NASA to 
pursue commercial opportunities for providing transportation to the 
International Space Station. The crew/cargo program is intended to spur 
private industry to provide cost-effective access to low-Earth orbit, 
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: a Heavy Lift Launch Vehicle (HLLV), leveraging 
engineering design and capabilities from the Shuttle Program; an Earth 
Departure Stage (EDS) to provide the momentum required to propel the CEV 
from LEO to Lunar Orbit; a Lunar Surface Access Module (LSAM) 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 Exploration Systems Research and Technology (ESRT) theme is 
NASA's investment in the technologies and capabilities that will make 
the national vision for space exploration possible. The goals of solar 
system exploration will be the primary focus of exploration systems 
research and technology, and 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 al

[[Page 1067]]

lowing pre-planned integration in support of evolving missions.

    Within ESRT there are five programs: Advanced Space Technology, 
Technology Maturation, Centennial Challenges, Robotic Lunar Exploration 
and Prometheus (previously a separate theme). The Advanced Space 
Technology Program develops new high leverage technologies and concepts. 
The Technical Maturation Program develops near term technologies for 
human robotic exploration and assures their timely transition into 
exploration systems mission development programs. The Centennial 
Challenges Program establishes awards to stimulate innovative technical 
accomplishments that could advance the state of civil space exploration 
and aeronautics. The Robotic Lunar Exploration Program develops 
precursor missions to characterize the lunar environment. The Prometheus 
program develops nuclear technologies for power and propulsion. NASA is 
working closely with other government agencies, industry, academia and 
other partners to leverage common requirements and identify innovative 
ideas.

    The Human Systems Research and Technology (HSRT) theme focuses on 
ensuring the health, safety, and productivity of humans as we embark on 
missions of exploration in our solar system. Programs within this theme 
advance knowledge and technology critical for supporting long-term human 
survival and performance during operations beyond Low Earth Orbit (LEO), 
with a focus on improving medical care and human health maintenance. 
Within HSRT there are three programs: Human Health and Performance 
(HHP); Life Support and Habitation (LSH); and Human Systems Integration 
(HSI). The HHP program delivers 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 LSH program conducts research and develops 
technology for life support and other critical systems for spacecraft 
operations. The HSI program focuses on optimizing human-machine 
interaction in the operation of spacecraft systems.

    Aeronautics research.--NASA aeronautics was built on the tradition 
of building expertise in the core disciplines of aeronautics and has 
been at the forefront of many major advances in the science of flight.

    NASA scientists and engineers have built a substantial base of 
knowledge and the analytic tools and capabilities to perform more 
exacting work to close the gap between experimental and theoretical 
knowledge. NASA has become the nation's leading government organization 
for aeronautical research, with a charter to develop an integrated 
strategy that addresses the challenges in aviation by developing 
technological solutions that will enable a bold new era in aviation.

    Although NASA is refocusing the Aeronautics Program to place greater 
emphasis on long-term investments in founda- tional research, we are 
maintaining our long-standing commitment to benefit the American public 
by developing technologies that accomplish the following goals:

    1. Make the nation's current and future air transportation system 
even safer;

    2. Protect local air quality and our global climate;

    3. Reduce aircraft noise to benefit airport neighbors, the aviation 
industry, and travelers;

    4. Enable the movement of more air passengers with fewer delays; and

    5. Enable people to travel faster and farther, anywhere, anytime.

    NASA's Aeronautics theme consists of three integrated research 
programs as well as an Aeronautics Test Program that preserves critical 
NASA wind tunnel infrastructure.

     The Fundamental Aeronautics Program will conduct research 
and develop technology to enable revolutionary capabilities for the 
future of aviation. We will develop advanced tools and capabilities that 
will enable whole new classes of aircraft that not only meet the noise 
and emissions requirements of the future but that also provide fast, 
efficient, and economical flight.

     The revectored Aviation Safety Program will focus NASA 
research on improving the inherent safety attributes of aircraft in 
order to eliminate fatal accidents and enhancing the safety of the 
nation's current and future national air transportation system.

     The Airspace Systems Program is being realigned to directly 
address the needs of the Next Generation Air Transportation System 
(NGATS) initiative as defined by the Federal Aviation Administration and 
NASA within the Joint Planning and Development Office (JPDO). NGATS 
research will enable major increases in the capacity and mobility of the 
U.S. air transportation system through development of technologies, 
capabilities, and future concepts.

    The Aeronautics Test Program is a new Aeronautics program that will 
ensure the strategic availability of a critical suite of wind tunnels 
which are deemed necessary to meet Aeronautics, Agency, and National 
needs.

    Cross-agency support programs.--Cross-Agency Support Programs 
includes four single-program themes that encompass several ongoing 
activities and an improved model for managing NASA's unique facilities. 
The themes are Education, Advanced Business Systems, Integrated 
Enterprise Management Program, Innovative Partnerships Program, and 
Shared Capability Assets Program.

    Education at 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.

    The Integrated Enterprise Management Program (IEMP) was placed in 
the new Advanced Business Systems theme beginning in FY 2006 as a direct 
funded program versus being funded within Corporate and Center General 
and Administrative (G&A) expenses.

    IEMP is a large and complex initiative changing the way financial 
and business management is performed throughout NASA. Center and/or 
Directorate unique approaches are being replaced with a single set of 
standard integrated business processes. Each and every NASA employee 
will be impacted by these changes. New IEMP systems are improving 
business processes by minimizing data redundancy, standardizing 
information and electronic data exchanges, processing and recording 
financial events effectively and efficiently, and ensuring consistent 
information throughout the Agency. IEMP consists of functional projects 
that effect business process changes and that acquire and implement 
appropriate information technology tools to substantially improve the 
Agency's performance. The program, reformulated in March 2000, will 
complete implementation in FY 2008. IEMP is composed of multiple 
projects. The following projects are completed and implemented: Resume 
Management, Position Description Management, Travel Management, Core 
Financials, Program Management Information Improvement, and Labor 
Distribution System. The following projects are in planning or devel

[[Page 1068]]

opment: SAP Upgrade, Contract Management, and Integrated Asset 
Management.

    NASA's Innovative Partnerships Program (IPP) is undergoing 
transition to improve value provided to NASA. The mission of the new IPP 
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 of the IPP include: leveraged technology investments, dual-use 
technology-related partnerships, and secured Intellectual Property 
assets. IPP partnerships serve to increase the range of technology 
solutions for NASA, enable cost avoidance, and accelerate technology 
maturation. IPP consists of the following program elements: Technology 
Transfer (T2), Space Products Development (SPD), Small Business 
Innovative Research (SBIR)/ Small Business Technology Transfer Program 
(STTR), and four of NASA's University Research Engineering & Technology 
Institutes (URETI). Together these 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 new 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 four specific key capability/asset classes that 
should be addressed initially to ensure that NASA retains the needed 
specialized assets and skills required to implement NASA's missions. 
These are wind tunnels, rocket propulsion testing, thermal vacuum 
chambers, and high performance computing capabilities. NASA has assessed 
the requirements in three of the initial four asset classes: wind 
tunnels, rocket propulsion testing, and high performance computing 
capabilities. While funding for these asset classes is in the mission 
directorates (wind tunnel in Aeronautics, rocket propulsion testing in 
Space Operations, and high performance computing capabilities in 
Science) all asset classes are managed in an integrated manner by the 
program. The requirements assessment for thermal vacuum chambers and 
decision as to location of funding are still in progress. After 
nomination, review, and selection by the Agency, assets and/or asset 
classes will be added to or withdrawn from the Shared Capability Assets 
Program account based on an overall prioritization and balance among the 
assets being considered, and within the overall constraints of Agency 
priorities and resources.

    This appropriation provides for the full costs associated with the 
Exploration Capabilities activities of the Agency, which include the 
International Space Station, Space Shuttle, and Space and Flight Support 
themes within 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 in the NASA chapter of the 2007 
President's Budget. The Exploration Capabilities activities include 
Space Operations, and are described below.

    Space operations.--Space Operations encompasses three themes: 
International Space Station, Space Shuttle Program, and Space and Flight 
Support. The International Space Station (ISS) is a complex of research 
laboratories in low Earth orbit (LEO) in which American, Russian, 
Canadian, European, and Japanese astronauts conduct unique scientific 
and technological investigations in a micro-gravity environment. The 
objective of the ISS is to support scientific research for human space 
exploration and maintain a permanent human presence in Earth orbit. The 
FY 2007 budget request provides funding for ISS launch processing 
activities, the continuation of ISS on-orbit assembly with a crew of 
three, and continuation of research payload and experiment deliveries to 
orbit. It also includes funding for development of habitability 
modifications and completion of the regenerative environmental control 
and life support system needed to increase the crew capacity, consistent 
with human space exploration research requirements.

    The Space Shuttle program's mission is to support space exploration 
by continuing to construct the ISS. The 2007 Budget request also 
supports one servicing mission to the Hubble Space Telescope contingent 
upon safety and technical feasibility assessments, which will be 
conducted after the next Shuttle flight. The 2007 Budget request will 
allow NASA to provide appropriate contingency resources to combat flight 
hardware obsolescence, maintain ground systems and facilities, and to 
initiate actions for an orderly phase-out of the program by 2010. In 
addition, the Shuttle program will work closely with the Exploration 
Systems Mission Directorate to integrate the application of Shuttle 
flight hardware and selected ground systems to advance the development 
of the Crew Exploration Vehicle/Crew Launch Vehicle and Heavy Lift 
Launch Vehicle.

    Space and Flight Support is comprised of four critical and distinct 
programs that provide on-going 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 for the conduct of space exploration, aeronautical research, 
and physiological research. They are provided to a wide range of 
customers including NASA, other U.S. federal agencies, foreign 
governments, and commercial interests.

    NASA's ``Human Space Flight'' account included the International 
Space Station; Space Shuttle Payload and Expendable Launch Vehicle 
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 Engineering, which was allocated as an 
indirect charge to all programs--along with the Crosscutting 
Technologies portion of the Aerospace Technology Enterprise, were 
included under the ``Space Flight Capabilities'' account. In FY 2005, 
the ``Space Flight Capabilities'' account was 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'', 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, [2008] 2009.
    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 accompanying the conference report for this Act.]
    [The unexpired balances of prior appropriations to 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 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.] 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.
