    This appropriation provides funding for Human Space Flight (HSF) 
activities, and for safety, mission assurance and engineering activities 
supporting the Agency. The HSF activities include development and 
operations of the Space Station and operation of the Space Shuttle. This 
includes high priority investments to improve the safety of the Space 
Shuttle, and required construction projects in direct support of Space 
Station and Space Shuttle programs. This appropriation also provides 
for: salaries and related expenses; design, repair, rehabilitation, and 
modification of facilities and construction of new facilities; 
maintenance, and operation of facilities; and other operations 
activities supporting human space flight programs; and space operations, 
safety, mission assurance and engineering activities that support the 
Agency.

    In 2001, the HSF account provided only for the direct funding of 
human space flight activities; space operations services had been funded 
within the Science, Aeronautics and Technology (SAT) account; and 
safety, mission assurance and engineering had been funded within the 
Mission Support account. Since 2002, other than direct costs (which 
includes Research and Program Management and non-programmatic 
Construction of Facilities) are allocated to either the HSF or the SAT 
account based on the number of full time equivalent people.

Performance Objectives

    Space Station.--The International Space Station (ISS) 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 microgravity 
environment. The goal of the Station is to support scientific research 
and other activities requiring the unique attributes of humans in space 
and establish a permanent human presence in Earth orbit. The President's 
2003 Budget request provides funding for continued development of the 
vehicle and for operations in support of continued assembly, logistics 
resupply, crew exchange, research operations and other utilization. With 
nine assembly missions successfully completed, the budget includes 
funding to keep subsequent assembly missions on schedule through U.S. 
Core Complete (Flight 10A), currently planned for calendar year 2004, to 
support early research commensurate with the build-up of on-orbit 
utilization capabilities and resources.

    In early calendar year 2001, NASA launched the U.S. Laboratory and 
the first set of research equipment necessary for conducting experiments 
on the Space Station. Subsequent flights enabled the installation of the 
Canadian robotic arm, additional research equipment for the U.S. 
Laboratory, installation of the Russian docking compartment, and 
transport of the 3rd and 4th crew expeditions. By mid-calendar year 
2001, the U.S. Airlock had been installed, allowing spacewalks to be 
conducted without the Space Shuttle present, and marking completion of 
Phase 2 of the Space Station assembly. The first utilization flight in 
December 2001 greatly expanded the number of research payloads on-orbit, 
and raised the number of research investigations initiated to over 40. 
Crew training, payload processing, hardware element processing, and 
mission operations were supported without major ground anomalies, and 
all but two on-orbit subsystems performed above predicted levels, 
resulting in a lower than expected maintenance workload. This lower 
maintenance workload, coupled with the commitment of the expedition 
crews to dedicate time for conducting research experiments, resulted in 
research activities that exceeded expectations. NASA will seek to exceed 
expectations for research productivity by achieving astronaut time 
dedicated to research in excess of the planned 20 hours per week. During 
2002, three of the major truss elements constituting the power block 
will be deployed to orbit, Expeditions 5 and 6 will be deployed, and a 
second utilization flight will expand science capabilities even further. 
In calendar year 2003, activation of the thermal system will be 
completed, two of the three remaning solar array modules will be 
deployed, and both the S6 truss and Node 2, the final components of the 
U.S. Core Complete, should be delivered to NASA for final integration 
and pre-flight test and checkout to support planned launches in calendar 
year 2004.

    As required by both the NASA Authorization Act (PL 106-391) and the 
2002 VA/HUD Appropriations Act (P.L. 107-73), the ISS research budget is 
transferred to the Biological and Physical Research Enterprise in 2002. 
The remaining ISS budget supports completion of the U.S. Core Complete 
and allows the program to press ahead with the integration of the 
partners' research modules. A NASA cost estimate, and an independent 
cost estimate (ICE) of the cost to assemble and operate the U.S. Core 
Complete will be completed by September 2002. The 2002 appropriation 
directed a general reduction in the station budget of $75M, which 
eliminated reserves fenced for guaranteed carryover into 2003. The 
appropriation also earmarked $40M for X-38 efforts that was originally 
planned to cover X-38 plus continued work on Node 3 and the advanced 
environmental control system. NASA plans to fund the Node 3 and 
environmental control work into the 2nd quarter of 2002, when a decision 
will be made to continue those efforts or to cancel them.

    Consistent with the recommendations in the ISS Management and Cost 
Evaluation (IMCE) Task Force, and direction from the Administration, 
NASA will develop a Cost Analysis Requirements Document (CARD) to 
support cost estimates of the U.S. Core Complete baseline. NASA will 
also develop an integrated management action plan based on 
recommendations of the IMCE Task Force, and begin implementation of 
those actions. NASA will also report to the Administration and to 
Congress its plans for a non-governmental organization (NGO) for ISS 
research, and the results of discussions with the International Partners 
on ways to increase on-orbit resources for station research, in 
particular innovative methods for increasing crew availability. The ISS 
Program is pressing ahead with final flight hardware deliveries, and 
completion of the current prime contract in December 2003. Requirements 
for follow-on support are being reviewed and estimated, and a plan to 
competitively award contracts for the station's operations phase will be 
released this Spring.

    Payload and Expendable Launch Vehicle (ELV) Support.--The Payload 
Carriers and Support budget provides technical expertise, facilities, 
flight carrier hardware and capabilities necessary to provide end-to-end 
servicing of multiple payloads to be flown aboard the Space Shuttle. 
During 2001, six pallets were used in Space Shuttle missions. In 2002 
and 2003, over 20 major and secondary payloads will be supported, 
including major hardware for International Space Station assembly and 
operations.

    The ELV Mission Support budget provides funds for technical and 
management insight of commercial launch services, including advanced 
mission design/analysis and leading-edge integration services, which are 
provided for the full range of NASA missions under consideration for 
launch on ELVs. During 2001, eight ELV missions were launched. 
Integration and technical management of 11 launches, including one 
secondary, are planned in 2002. In 2003, support for ten launches, 
including one secondary, is planned.

    Investments and Support.--NASA's rocket propulsion test project will 
ensure that unique capabilities are properly managed and maintained in 
world-class condition. The project will significantly enhance NASA's 
ability to properly manage rocket testing activities and infrastructure 
across all four participating NASA centers. Engineering and technical 
base (ETB) activity will continue to: support the institutional 
capability in the operation of space flight laboratories, technical 
facilities, and testbeds; conduct independent safety, and reliability 
assessments; and stimulate science and technical competence in the 
United States. Funding for other direct costs associated with Human 
Space Flight, which were funded in the Mission Support account prior to 
2002, are also funded within investments and support. This includes 
research and program management costs and non-programmatic construction 
of facilities costs.

    Space Shuttle.--The Space Shuttle is a partially reusable space 
vehicle that provides several unique capabilities to the United States 
space program. These include retrieving pay-loads from orbit for reuse, 
servicing and repairing satellites in space, safely transporting humans 
to and from space, launching ISS components and providing an assembly 
platform in space, and operating and returning space laboratories.

    In 2001, the Space Shuttle launched seven flights, all of which were 
ISS assembly and servicing missions. Seven flights are planned during 
2002 including a dedicated microgravity research flight and another HST 
Servicing Mission (HST-3B) and five ISS assembly and servicing missions. 
In

[[Page 1025]]

2003, four flights are planned, all of which are ISS assembly and 
servicing missions. In support of the research objectives of the Space 
Station, the Space Shuttle will commit a minimum of five powered mid-
deck lockers on each mission to deliver necessary research equipment and 
specimens.

    NASA will aggressively pursue Space Shuttle competitive sourcing as 
an important step in transitioning NASA from infrastructure ownership 
and operation to purchasing space transportation services where 
possible. NASA will seek industry comment on its plans early this year, 
leading to release of a solicitation for competitive sourcing. NASA will 
prepare a Cost Analysis Requirements Document (CARD) to support NASA and 
independent cost estimates of Space Shuttle operations and safety 
investments, similar to estimates being done for the Space Station. 
These estimates, to be completed by September, 2002, will provide an 
important baseline from which to assess competitive sourcing options.

    The President's 2003 Budget supports key Space Shuttle safety 
investments as part of NASA's Integrated Space Transportation Plan. NASA 
will seek to accelerate the implementation of safety investments, to 
begin achieving safety gains in Shuttle operations as quickly as 
possible. The President's 2003 Budget also supports investments in the 
Space Shuttle infrastructure, as necessary to address safety issues and 
critical repair and revitalization activities.

    Space Communications and Data Systems.--The program goal is to 
support NASA's Enterprises and external customers with Space 
Communications and Data System (SCDS) services that are responsive to 
customer needs. Additionally, the program performs infrastructure 
upgrades and replenishment efforts necessary to maintain the service 
capabilities that satisfy the approved mission model. The program 
conducts technology and standards infusion efforts to provide more 
efficient and effective services. The Space Communications Office at 
Headquarters manages and directs an integrated Agency-wide Space 
Communications and Data Systems program.

    Beginning in 2002, a decentralized management process has been 
implemented that involves transferring most management and budget 
responsibilities previously performed by the Space Operations Management 
Office to the appropriate Enterprises. Beginning in 2003, the Deep Space 
Network, Ground Network and Western Aeronautical Test Range will be 
managed by NASA's Enterprises. The Office of Space Flight will continue 
to perform overall program integration, including the management of 
Consolidated Space Operations Contract, which is now in its fourth year 
of providing data services to both NASA and non-NASA customers.

    The TDRS-8 spacecraft, which completed on-orbit checkout in 
September 2000, is working well and meets all user service 
telecommunications performance requirements except for a Multiple Access 
(MA) performance anomaly. Modifications to the TDRS-I and TDRS-J 
spacecraft flight hardware and test program as a result of the MA 
investigation have been implemented. TDRS-I launch is now planned for 
February 2002. The launch of TDRS-J is slated for October 2002.

    Safety, Mission Assurance and Engineering.--The Safety and Mission 
Assurance program invests in the safety and success of NASA missions by 
assuring that sound and robust policies, processes, and tools for 
safety, reliability, quality assurance, and engineering disciplines are 
in place and applied throughout NASA. The program also examines long-
term technology requirements for NASA's strategic objectives. The 
Engineering program, managed by the Office of the Chief Engineer (OCE), 
oversees the conduct and improvement of NASA's engineering practice and 
independently evaluates ongoing programs, proposed concepts, and options 
for new programs. The OCE establishes policies, standards, guidance, and 
support for improving NASA engineering practices and technical 
capabilities, and manages the NASA Electronics Parts and Packaging 
Program, which supports evaluation and infusion of advanced electronic 
parts and packaging technology into NASA programs.

    This appropriation provides for the Science, Aeronautics and 
Technology (SAT) supporting the Agency. The SAT activities include space 
science, biological and physical research including research for the 
International Space Station, earth science, aerospace technology, and 
academic programs. This appropriation also provides for salaries and 
related expenses; design, repair, rehabilitation, and modification of 
facilities and construction of new facilities; maintenance and operation 
of facilities; and other operations activities supporting science, 
aeronautics, and technology programs.

    In 2001, the SAT account provided only for the direct funding of 
science, aeronautics and technology activities, and included funding for 
space operations services which are now funded within the Human Space 
Flight (HSF) account. Since 2002, other direct costs (which include 
Research and Program Management and non-programmatic Construction of 
Facilities) are allocated to either the HSF or the SAT account based on 
the number of full time equivalent personnel.

Performance Objectives

    Space Science.--The Space Science program seeks to answer 
fundamental questions concerning: the galaxy and the universe; the 
connection between the Sun, Earth and heliosphere; the origin and 
evolution of planetary systems; and the origin and distribution of life 
in the universe. The Space Science program is comprised of many research 
and development activities, including flight missions, major space-based 
facilities, technology and mission development programs, and research 
and data analysis.

    In 2001, the Space Science program produced many notable scientific 
results: The Hubble Space Telescope discovered a supernova blast that 
occurred very early in the life of the Universe, bolstering the case for 
the existence of a mysterious form of ``dark energy'' pervading the 
Universe. The concept of dark energy, which pushes galaxies away from 
each other at an ever-increasing speed, was first proposed, then 
discarded, by Albert Einstein early in the last century. The Hubble 
discovery also reinforces the startling idea that the expansion of the 
universe only recently began speeding up.

    The Chandra X-ray Observatory enhanced our understanding of black 
holes on many fronts. Chandra took the deepest X-ray images ever and 
found the early Universe teeming with black holes, probed the 
theoretical edge of a black hole known as the event horizon, and 
captured the first X-ray flare ever seen from the supermassive black 
hole at the center of our own Milky Way galaxy.

    Detailed scientific analysis of high-resolution images obtained by 
the BOOMERANG (Balloon Observations of Millimetric Extragalactic 
Radiation and Geophysics) mission provided the most precise measurements 
to date of several of the key characteristics cosmologists use to 
describe the Universe. These images were the first to bring the cosmic 
microwave background (the radiation remaining from the ``big bang'' that 
created the Universe) into sharp focus.

    In addition to these discoveries that have enhanced our 
understanding of the origin, evolution, and structure of the Universe, 
many discoveries in 2001 related to the rapidly growing field of 
extrasolar planet (planets outside our Solar System) detection. NASA and 
National Science Foundation-funded astronomers discovered eight new 
extrasolar planets, bringing the total number of extrasolar planet 
detections to about eighty. Observations from the Submillimeter Wave As

[[Page 1027]]

tronomy Satellite (SWAS) provided the first evidence that extrasolar 
planetary systems contain water, a molecule that is an essential 
ingredient for known forms of life. Also in this field, astronomers 
using the Hubble Space Telescope have made the first detection and 
chemical analysis of the atmosphere of a planet outside our Solar 
System.

    Within our Solar System, NASA spacecraft made many stunning 
achievements in 2001. In a risky flyby, the Deep Space-1 spacecraft 
successfully navigated past comet Borrelly, giving researchers the best 
look ever inside a comet's glowing core of icy dust and gas. Deep Space-
1 passed just 2,200 kilometers (1,400 miles) from the rocky, icy nucleus 
of the 10 kilometer-long (more than 6 mile-long) comet. The NEAR (Near 
Earth Asteroid Rendezvous) Shoemaker spacecraft achieved the first soft 
landing on an asteroid. The landing was the culmination of a year-long 
orbital mission at the asteroid Eros during which the mission returned 
enormous quantities of scientific data and images.

    A pair of spacecraft, the Mars Global Surveyor and the Hubble Space 
Telescope, provided astronomers with a ringside seat to the biggest 
global dust storm seen on Mars in several decades. The Martian dust 
storm, larger by far than any seen on Earth, raised a cloud of dust that 
engulfed the entire planet for several months. The sun-warmed dust 
raised Martian atmospheric temperatures by 80 degrees Fahrenheit while 
the shaded Martian surface chilled precipitously. Also in calendar year 
2001, the Mars Odyssey 2001 spacecraft successfully achieved orbit 
around Mars following a six-month, 286-million mile journey. Following 
aerobraking operations, this spacecraft will be placed in its science-
mapping orbit in early calendar year 2002 and will characterize 
composition of the Martian surface at unprecedented levels of detail.

    In the field of Sun-Earth Connections, where we seek to develop a 
scientific understanding of the physical interactions in the Sun-Earth 
system, there were several important scientific accomplishments in 
calendar year 2001. The Solar and Heliospheric Observatory (SOHO) 
observed the largest sunspot in ten years, with a surface area 
equivalent to thirteen Earths. This area proved to be a prolific source 
of stormy solar activity, hurling clouds of electrified gas (known as 
Coronal Mass Ejections, or CMEs) towards Earth. Other studies conducted 
by the SOHO spacecraft have provided the first clear picture of what 
lies beneath sunspots, peering inside the Sun to see swirling flows of 
electrified gas that create the self-reinforcing cycle that holds a 
sunspot together.

    The calendar year was capped by the successful launch of the TIMED 
(Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) mission 
on December 7, 2001. This is the first mission in the Solar Terrestrial 
Probes program. It will study a region of the Earth's atmosphere that 
has never been the subject of a comprehensive, long-term scientific 
investigation.

    The NASA budget request for 2003 features two very significant 
changes from the previous baseline program: a reformulated planetary 
program and the inclusion of a nuclear power and propulsion program. In 
the field of planetary exploration, the 2003 Budget takes a 
fundamentally different approach from previous years. Given cost growth 
and schedule delays, all funding for the Pluto-Kuiper Belt mission and 
the Europa Orbiter mission has been eliminated in 2003 and subsequent 
years. These missions will be replaced by a revamped planetary program 
that will incorporate the following principles: clear science priorities 
that support key goals in understanding the potential existence of life 
beyond Earth and the origins of life; open competition and rigorous 
reviews of cost, schedule, and risk to minimize future overruns and 
delays per the highly successful Discovery Program; and an architectural 
approach that balances science return in this decade with investments in 
high-leverage technologies that will enable faster and more frequent 
missions with greater science return in the next decade. It is 
envisioned that the new planetary program will be structured and managed 
along the lines of the highly successful Discovery program. A key 
element of this new program will be the development and incorporation of 
nuclear power and propulsion technologies. Building upon ongoing NASA 
investments in advanced electric propulsion and instrument and 
electronics miniaturization, investments in nuclear power and nuclear-
electric propulsion technologies that will enable much faster and more 
frequent planetary investigations with greater science capabilities. 
These investments will allow NASA to undertake fundamentally new 
approaches to planetary exploration. In the next decade, nuclear-
electric propulsion technology will enable affordable planetary missions 
that: can reach targets in half the time it would take using today's 
propulsion systems; are not limited by today's power and mass 
constraints; and can conduct long-term observations of multiple targets.

    Nuclear power technology will also be incorporated into the Mars 
Exploration Program, specifically in the Mars Smart Lander/Mobile 
Laboratory mission. This mission will now be launched in calendar year 
2009 to allow the incorporation of nuclear power, instead of calendar 
year 2007 as previously planned. By using nuclear power, the time during 
which the Mars Mobile Laboratory can conduct science operations will be 
extended from several months to several years. The nearer-term missions 
in the Mars Exploration Program remain essentially unchanged. In May and 
June of 2003, two highly capable surface rovers will be launched to 
Mars, with landings on the surface expected in April and May of 2004. 
The Mars Reconnaissance Orbiter (MRO) will be launched in calendar year 
2005; this powerful scientific orbiter will focus on analyzing the 
surface at unprecedented levels of detail to follow tantalizing hints of 
water detected in images from the Mars Global Surveyor spacecraft. MRO 
will measure thousands of Martian landscapes at 20- to 30-centimeter (8- 
to 12-inch) resolution. It will be followed by a competitively selected 
Mars Scout mission in calendar year 2007 and the Smart Lander/Mobile 
Laboratory in calendar year 2009. This robust program of orbiters, 
landers, and rovers is poised to unravel the secrets of the red planet's 
past environments, the history of its rocks, the many roles of water, 
and, possibly, evidence of past or present life.

    This Budget supports the completion of development of many 
significant missions, including Gravity Probe-B (GP-B), the Space 
Infrared Telescope Facility (SIRTF), and the Stratospheric Observatory 
For Infrared Astronomy (SOFIA). GP-B, which will verify a key aspect of 
Einstein's theory of general relativity, will be launched in October 
2002. SIRTF, the fourth and final of the Great Observatories, is 
scheduled for launch in 2003. SOFIA development activities will 
continue, with the aircraft door and the telescope to be installed and 
tested in 2003. Development activities supporting the Solar Terrestrial 
Relations Observatory (STEREO), the Gammaray Large Area Space Telescope 
(GLAST), the final Hubble Space Telescope servicing mission, as well as 
several key missions in the payloads program such as Solar-B and 
Herschel, will also continue in 2003.

    In the Explorer program, the Microwave Anisotropy Probe successfully 
launched on June 30, 2001, and development of Swift, a multi-wavelength 
observatory for gammaray burst astronomy, remains on schedule for a 
September, 2003 launch. Another MIDEX mission, the Full-sky Astrometric 
Mapping Explorer (FAME), did not pass confirmation review due to cost 
increases and was not approved for full-scale development. Selection of 
the MIDEX-5 and MIDEX-6 missions will occur in 2002, and an Announcement 
of Opportunity for MIDEX-7 and MIDEX-8 will be released in 2003. In the 
Small-class (SMEX) mission series, three NASA missions and two non-NASA 
Missions of Opportunity are sup

[[Page 1028]]

ported. The NASA missions include the Galaxy Evolution Explorer (GALEX), 
Two Wide-Angle Neutral Atom Spectrometers (TWINS), and the High Energy 
Solar Spectroscopic Imager (HESSI). The Missions of Opportunity are the 
Coupled Ion Neutral Dynamics Investigation (CINDI; a cooperative mission 
with the Air Force), and ASTRO E-2, an X-ray astronomy mission (in 
cooperation with Japan). ASTRO E-2 is a rebuild of ASTRO E, which was 
lost due to a failure of the Japanese launch vehicle in February, 2000.

    In the Discovery program, the Genesis mission was launched on August 
8, 2001; it has begun collecting samples of charged particles from the 
solar wind, and it will return these samples to Earth for analysis in 
calendar year 2004. Development activities continue on three other 
Discovery missions. The Comet Nucleus Tour (CONTOUR) will be launched in 
July 2002, and it will encounter two comets: comet Encke in calendar 
year 2003, and comet Schwassman Wachman-3 in calendar year 2006. The 
Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) 
mission to orbit Mercury, and the Deep Impact mission to fly by and fire 
an impactor into comet Temple-1, are both scheduled to launch in early 
calendar year 2004.

    The New Millennium program is providing flight demonstrations of 
critical new technologies that will reduce the mass and cost of future 
science and spacecraft subsystems, while maintaining or improving 
mission capabilities. In calendar year 2003, the Nanosat Constellation 
Trailblazer (Space Technology-5, or ST-5) will undergo spacecraft and 
instrument integration and test in preparation for launch in calendar 
year 2004. Also in calendar year 2003, the Critical Design Review for 
ST-6 will be conducted, as will the Confirmation Review for ST-7, and 
the initial confirmation for ST-8.

    The President's 2003 Budget also provides funding for focused 
technology programs in each of the four major Space Science themes: the 
Astronomical Search for Origins, Structure and Evolution of the 
Universe, Solar System Exploration, and Sun-Earth Connections, which 
includes both the Living With A Star Program and the Solar Terrestrial 
Probes Program. These funds provide for early technology development in 
support of strategic missions such as the Next Generation Space 
Telescope and the Space Interferometry Mission. The goal is to retire 
technology risk early in a mission's life-cycle, before proceeding to 
full-scale development. Funds are also provided to continue on-going 
operations of approximately thirty spacecraft, and to conduct robust 
research and analysis, data analysis, and suborbital research campaigns.

    Biological and Physical Research.--The Biological and Physical 
Research Enterprise (BPRE) seeks to exploit the rich opportunities of 
space flight for fundamental research in the biological and physical 
sciences, as well as in commercial development of space, and conducts 
research to enable efficient and effective systems for protecting and 
sustaining humans in space. BPRE seeks to achieve advances in biological 
and physical sciences by understanding nature's forces in space, and 
achieve an understanding of the human experience in space.

    In late 2001, BPRE was created as NASA's fifth strategic enterprise. 
BPRE closed its first fiscal year with a significant record of 
accomplishment. It expanded its interagency research collaborations, 
establishing a new memorandum of understanding with the United States 
Department of Agriculture, conducting a joint research solicitation with 
the National Cancer Institute, and continuing work under 18 other 
agreements with the National Institutes of Health. A BPRE investigator 
received the Nobel Prize in physics for ground-based research that he 
plans to extend and expand on the International Space Station. 
Outfitting the International Space Station (ISS) for research began with 
the delivery of the Human Research Facility in March 2001. Two research 
equipment racks were delivered to the ISS in mid-April and an additional 
two at the beginning of Expedition 3 in August. BPRE initiated a program 
of research on the ISS to take advantage of available resources during 
the construction phase. The ISS Expedition 1 and 2 teams were able to 
exceed expectations for meeting research objectives of the planned 
experiments, with only one unsuccessful experiment due to technical 
reasons.

    In 2002, BPRE will continue to increase knowledge and demonstrate 
key technology capabilities for humans in space, address critical 
questions in crew health and safety, and materials science and 
commercial research payloads will be flown on both the Space Shuttle and 
aboard ISS. The Space Station research program is on track to deliver 
another five equipment racks on orbit by the end of calendar year 2002. 
BPRE also will complete definition studies leading to award of a 
contract to manage ISS utilization to a Non-Governmental Organization 
(NGO). Working with the scientific community, its advisory committees, 
and the Administration, BPRE will complete the development of research 
priorities across its portfolio of research endeavors to provide a basis 
for critical resource allocation decisions. In the area of public 
outreach and education, BPRE plans to develop electronic and printed 
educational materials that focus on biological and physical research.

    In 2003, BPRE will implement its research priorities and develop ISS 
flight facilities to achieve a prioritized and productive research 
program. BPRE will also work with Life Science Museum Network members to 
explore opportunities for the development of projects, special events, 
or workshops focused on the life sciences and biology-related research 
themes to attract and engage public audiences. In addition, BPRE will 
make available to wide audiences an online database of Commercial Space 
Center activities, including publications listings, patents, and other 
information useful to the general public.

    Earth Science.--The mission of NASA's Earth Science Enterprise (ESE) 
is to develop a scientific understanding of the Earth system and its 
response to natural and human-induced changes to enable improved 
prediction of climate, weather and natural hazards for present and 
future generations. ESE seeks to answer a question of fundamental 
importance to science and society: How is the Earth system changing, and 
what are the consequences for life on Earth? To do so, ESE is developing 
the interdisciplinary research field of Earth System Science, which 
recognizes that the Earth's land surface, oceans, atmosphere, ice 
sheets, and life itself all interact in a highly dynamic system. Earth 
system science is an area of research with immense benefit to the 
Nation, leading to new knowledge and tools that may improve weather 
forecasting, agriculture, urban and regional planning, environmental 
quality, and natural disaster management. ESE has established three 
goals to pursue in order to fulfill its mission: (1) Science--observe, 
understand, and model the Earth system to learn how it is changing, and 
the consequences for life on Earth; (2) Applications--expand and 
accelerate the realization of economic and societal benefits from Earth 
science, information, and technology; (3) Technology--develop and adopt 
advanced technologies to enable mission success and serve national 
priorities.

    In ESE Science, 2001 was another year of substantial accomplishment 
toward understanding the Earth system. Goddard Space Flight Center 
(GSFC) produced the first global record of the Earth's biosphere, 
showing the uptake and release of carbon by land and oceans continuously 
over three years. NASA-sponsored research showed that the growing sea

[[Page 1029]]

son over parts of the Northern hemisphere has lengthened over the past 
two decades, with an accompanying increase in lushness of vegetation. 
NASA and the EarthSAT Corporation released the first consistent 30-m 
resolution land cover map for the U.S., and are nearing completion of 
the global map. These data are from calendar year 1990 and provide a 
basis for comparison of future change; plans are being developed to 
repeat the process for calendar year 2001 and beyond. Results from a 
major NASA/NSF-led international research campaign indicate that 
aerosols from dust and pollution may be reducing evaporation and thus 
slowing the global water cycle. Results from comparing the 2000 and 1997 
Antarctic Mapping Missions have led to new estimates of change in the 
Antarctic ice sheet; ice in the Lambert glacier flows from the interior 
to the ``mouth'' where it reaches a rate of 1 kilometer per year. In the 
Northern hemisphere, NASA researchers identified patterns of change in 
sea ice extent over a twenty-year period; overall, Arctic sea ice extent 
has decreased since calendar year 1978. Continued monitoring of global 
ocean topography showed that the Pacific Decadal Oscillation governs 
climate impacts of the Pacific in non-El Nino/La Nina years, and allowed 
the prediction of last winter's chill across the northern U.S. and 
relative warmth across the South. ESE also made major advances in 
computing for climate modeling, using a partnership among two NASA 
Centers and Silicon Graphics, Inc. to simulate 900 days of Earth's 
climate in one day, up from the prior capability of 70 days per day; 
performance on end-to-end climate simulation improved ten-fold. This 
greatly enhances climate modelers' ability to perform the multiple runs 
of many years of climate simulations needed to generate useful 
projections of climate change.

    In ESE Applications, ESE has entered into a variety of partnerships 
that will apply the goods and services made possible by ESE's research. 
ESE provides QuikSCAT data in real time to the National Oceanic and 
Atmospheric Administration (NOAA) to improve marine weather forecasting, 
and has used these data to show that severe storms forming over the 
oceans can be predicted two days in advance. ESE is working with the 
Federal Emergency Management Agency (FEMA) to use remote sensing tools 
to update their flood plain maps throughout the U.S. In a partnership 
called Agriculture 2020 with the U.S. Department of Agriculture (USDA) 
and four growers associations representing 100,000 farmers, ESE is 
demonstrating how to increase crop productivity, reduce risks to crop 
health, and manage environmental impacts. With the National Institutes 
of Health, we are exploring the use of satellite data to predict spread 
of infectious diseases such as malaria that are highly influenced by 
weather and climate. Throughout the summer, three ESE satellites tracked 
devastating wildfires in the western U.S., providing data to the U.S. 
Forest Service (USFS) and regional authorities. As a result, USFS is 
investing in direct broadcast receiving stations to rapidly acquire data 
from NASA's Terra satellite.

    In ESE Technology, the Enterprise's first New Millennium Program 
satellite to demonstrate a variety of new technologies for Earth Science 
successfully completed all its demonstration tasks (save one high-risk 
propulsion task scheduled for near the end of mission life). These 
include a new instrument to produce a Landsat-type sensor one-fourth the 
size of the current Landsat 7 instrument, and the first hyperspectral 
imager in space, which views the land surface in hundreds of spectral 
channels rather than the conventional five to seven channels. Sponsored 
technology research with universities, industry and other government 
laboratories moved 35% of ESE's new remote sensing instrument concepts 
one step closer to reality on an established scale of technology 
maturity. These advances will substantially reduce the cost and enhance 
the capability of new satellites over the next decade or more. ESE also 
began formation flying of four land imaging satellites, demonstrating 
that several smaller satellites can be operated in tandem to 
dramatically increase spatial and temporal coverage.

    ESE is in the midst of deployment of the Earth Observing System 
(EOS), a set of spacecraft and associated interdisciplinary science 
investigations to initiate a long-term data set of key parameters 
required for the study of global climate change. The first six EOS 
satellites are already in orbit, including Jason-1 and SAGE III, 
launched in December 2001. The remaining EOS satellites will be launched 
through calendar year 2004, including Aqua (calendar year 2002) to study 
the water cycle and atmospheric circulation, and Aura (calendar year 
2004) to probe the chemistry of the upper and lower atmosphere. 
Complementing EOS is a series of small, focused Earth System Science 
Pathfinder missions to explore Earth system processes never before 
examined globally from space. Data from the EOS satellites already in 
orbit are being acquired, processed, and distributed by the EOS Data and 
Information System (EOSDIS), which is currently handling more than 1 
terabyte of data per day. EOSDIS handled 12.3 million user queries for 
over 15 million products in calendar year 2001. EOSDIS continues to 
evolve as new satellites are launched, and as new partners are added to 
produce data products with innovative applications.

    As it deploys EOS, ESE is also planning for the future. ESE and U.S. 
Geological Survey (USGS) released a request for proposal for Landsat 
Data Continuity Mission to succeed Landsat 7; it is being implemented as 
a commercial data purchase. ESE is also planning for the transition of 
several of its key research observations to the Nation's weather 
satellite system. The Department of Defense (DoD), NOAA and NASA have 
established an Integrated Program Office (IPO) to create a converged 
civilian and military weather satellite system called the National 
Polar-orbiting Operational Environmental Satellite System (NPOESS) to 
replace the present generation of separate systems. NASA and the IPO are 
jointly funding the NPOESS Preparatory Project (NPP) that will 
simultaneously continue key measurements begun by EOS and demonstrate 
instruments for NPOESS. The NPP will save money for both NASA and NOAA 
by combining essential atmospheric and Earth surface observations on a 
single platform, and by seeking to meet both climate science and 
operational weather requirements with the same advanced instruments.

    ESE data products and research are a major contribution to the U.S. 
Global Change Research Program, an interagency collaboration overseen by 
the Committee on Natural Resources of the National Science and 
Technology Council. NASA ESE will also contribute to the new Climate 
Change Initiative, a multiagency effort with strong focus on outcomes. 
Because Earth science is inherently global in scope, ESE is engaged in a 
variety of international partnerships with individual nation's space 
agencies, and with international consortia such as the World 
Meteorological Organization. ESE seeks and receives scientific advice on 
a broad range of topics from the various boards and committees of the 
National Research Council. These partnerships, together with those 
above, ensure that NASA's Earth Science Enterprise conducts research at 
the frontiers of Earth science on questions of practical importance to 
the Nation.

    Aerospace Technology.--The Aerospace Technology (AST) Enterprise 
mission is to pioneer the identification, development, verification, 
transfer, application, and commercialization of high-payoff aerospace 
technologies and the development of broad, crosscutting revolutionary 
innovations critical to a number of NASA missions. The Enterprise plays 
a key role in: 1) maintaining a safe and efficient national aviation 
system, 2) enabling affordable, reliable space transportation systems, 
and 3) developing basic technologies for a broad range of space 
applications. Research and development pro

[[Page 1030]]

grams conducted by the Enterprise contribute to NASA's science and 
exploration missions, national security, economic growth, and the long-
term competitiveness of American aerospace companies. The Enterprise 
directly supports national policy in both aeronautics and space as 
directed in the President's Goals for a National Partnership in 
Aeronautics and Research Technology, the National Space Policy, and the 
National Space Transportation Policy.

    A modern air and space transportation system is fundamental to our 
national economy, quality of life, and security of the United States. 
For 75 years, a strong base for aerospace technology research and 
development has provided enormous contributions to this system, 
contributions that have fostered the economic growth of our Nation and 
provided unprecedented mobility for U. S. citizens. Although major 
technical advances have made our Nation's air and space transportation 
system the largest and best of its kind, the future holds critical 
challenges to its continued growth and performance. Because the U. S. 
air and space transportation system serves both the public good and 
critical national security needs, ensuring the continued health and 
preeminence of that system is a key issue for the future of the Nation.

    Although NASA technology benefits the aerospace industry directly, 
the creative application of NASA's advanced technology to disparate 
design and development challenges has made numerous contributions to 
other areas such as the environment, surface transportation, and 
medicine.

    In order to develop the aerospace systems of the future, 
revolutionary approaches to system design and technology development 
will be necessary. Pursuing technology fields that are in their infancy 
today, developing the knowledge bases necessary to design radically new 
aerospace systems, and performing efficient, high-confidence design and 
development of revolutionary vehicles are challenges that face us in 
innovation. These challenges are intensified by the demand for safety in 
our highly complex aerospace systems.

    The President's 2003 Budget provides the resources necessary to 
maintain the progress required to achieve a 21st Century aviation system 
that is safe, environmentally friendly, efficient and meets the growing 
demands for increased and predictable performance. The President's 2003 
Budget also supports technology development for space transportation 
systems that are safer and significantly less costly than today's 
systems. The structure of the Aerospace Technology budget has been 
changed so that the budget lines are directly linked to the Enterprise 
Strategic Goals. The first goal, Revolutionize Aviation, addresses 
fundamental, systemic issues in the aviation system to ensure continued 
growth and development appropriate to the needs of the national and 
global economies. These systemic issues--safety, capacity, environmental 
compatibility, and mobility--cut across markets including large subsonic 
civil transports, air cargo, commuter and general aviation. NASA 
coordinates its investments and technology objectives in this area with 
the Federal Aviation Administration (FAA) and the Department of Defense 
through the National Research and Development Plan for Aviation 
Security, Efficiency, and Environmental Compatibility. In 2003, the 
President's Budget provides for the demonstration of several advanced 
technologies that when implemented will result in a significant 
reduction in aviation accidents. Specific flight evaluations will 
include an integrated Synthetic Vision System and Runway Incursion 
Prevention System intended for use on commercial and business aircraft, 
a next-generation cockpit weather information digital datalink and 
turbulence awareness system, and a smart icing management system which 
will automatically activate and manage an aircraft's ice protection 
systems. In addition, ground-based demonstrations of an advanced vehicle 
health management system, an engine disk crack detection monitoring 
system and recovery methods for flight critical systems will be 
accomplished. The Administration's request also provides for continued 
development of the technologies necessary to reduce the environmental 
impact of today's aircraft. The sector testing of a jet engine combustor 
that could reduce nitrous oxide emissions by 70 percent will be 
complete. Selection of contractors to proceed with full annular testing 
for large and regional jet engines will also be complete. Additionally, 
the Administration's request includes funding for the development of a 
broad suite of advanced technologies that will provide the basis for 
future emission reductions including carbon dioxide. The request also 
includes the continuation of the noise reduction technology that in 
calendar year 2007 will reduce the perceived aircraft noise pollution by 
a factor of two from the calendar year 1997 baseline set by the 
International Civil Aviation Organization (ICAO). The budget request 
also continues to transfer to the Federal Aviation Administration 
technologies required to safely increase the use of the National 
Airspace System (NAS). In order to define future technology investments 
in this area, the Virtual Airspace Modeling and Simulation project will 
provide state-of-the-art models of the airspace system which have the 
capability to model the dynamic effects of interactive agents in the 
NAS. These models will provide the capability to assess the economic 
impact of new technologies on the operational performance of the NAS and 
thus guide future technology development. The budget request continues 
the Small Aircraft Transportation System (SATS) demonstration program. 
In 2003, SATS will select candidate technologies for experimental flight 
evaluation based on their impact on mobility--either through reduced 
system cost, improved doorstep-to-destination time, increased trip 
reliability, and/or improved safety--and complete initial lower landing 
minimum and higher volume flight experiments. Building on its altitude 
world-record-setting performances, the Environmental Research Aircraft 
and Sensor Technology (ERAST) project will demonstrate a solar power 
unpiloted air vehicle with the ability to fly 14 hours above 50,000 
feet. The accomplishment of this goal could have significant impact on 
the application of these systems in disaster relief, communications, 
environmental sensing, and defense.

    The second goal, Advance Space Transportation, will create a safe, 
affordable highway through the air and into space by improving safety, 
reliability, and operability, and significantly reducing the cost of 
space transportation systems. With the creation of the Integrated Space 
Transportation Plan (ISTP), NASA defined a single, integrated investment 
strategy for all its space transportation efforts, including Space 
Shuttle safety investments, the Space Launch Initiative (SLI), and 3rd 
Generation Space Transportation Technology. By investing in a sustained 
progression of research and technology development, NASA will enable 
future generations of reusable launch vehicles and in-space 
transportation systems that will surmount the Earth-to-orbit challenge 
and allow less costly, more frequent, and more reliable access to 
neighboring planets and the stars beyond. As planned in the 2002 Budget, 
the President's 2003 Budget request includes an increase in funding for 
the Space Launch Initiative (SLI), which supports the 2nd Generation 
Reusable Launch Vehicle (RLV) Program. In 2001, NASA awarded 23 
contracts under the 2nd Generation RLV Program for study and risk 
reduction activities across many technical areas, including: airframes, 
vehicle subsystems, operations, integrated vehicle health management, 
flight mechanics, NASA-unique systems, and propulsion. In 2003, the Main 
Engine Prototype Critical Design Review and the Systems Requirements 
Review will be complete and the Architecture Systems Requirements 
Document will be baselined. Upon completion of these activities, NASA 
will

[[Page 1031]]

downselect to a minimum of two space transportation architectures for 
continued development based on their ability to meet safety and 
affordability goals. This selection will determine what architectures 
and critical technology developments will be continued through 2006. The 
successful completion of 2nd Generation RLV Program risk reduction and 
technology development will enable a mid-decade competition to 
transition all of NASA's launch needs, including human space flight, to 
safer, lower cost, commercially competitive, privately operated vehicles 
at the turn of the decade. In 3rd Generation Space Transportation 
Technology, the Department of Defense and NASA have collaborated on an 
integrated science and technology plan for hypersonics research, the 
National Hypersonic Science and Technology Plan (NHP), which defines a 
national effort to address numerous challenges. The plan addresses 
airbreathing propulsion or, in some cases, combined rocket/airbreathing 
(RBCC) or turbine/airbreathing propulsion (TBCC) cycles. While pure 
rockets have already achieved hypersonic speeds, airbreathing 
technologies could offer significant benefits over rocket propulsion in 
performance and cost. In 2003, NASA will complete the independent 
evaluation of three competing, revolutionary hypersonic propulsion 
technology systems demonstrations, including an RBCC engine, a TBCC 
engine and a scramjet engine.

    The third goal, Pioneer Technology Innovation, focuses on broad, 
crosscutting innovations critical to a number of NASA missions and to 
the aerospace industry in general. Pursuing technology fields that are 
in their infancy today, developing the knowledge bases necessary to 
design radically new aerospace systems, and developing tools for 
efficient, high-confidence design and development will enable a 
revolution in aerospace. The Administration's request includes a 
significant investment in computing and information technology 
developments and also increases investment in biotechnology and 
nanotechnology--the revolutionary technologies of the 21st Century. To 
ensure the highest quality research and strong ties to NASA's missions--
Space Science, Earth Science, Biological and Physical Research, Human 
Space Flight, and Aerospace Technology--these investments will be guided 
by technology development agreements signed by customers in other NASA 
Enterprises.

    Beginning in 2002, NASA will have the National Academy of Sciences 
undertake reviews of one of these three program areas--Revolutionize 
Aviation, Advance Space Transportation, and Pioneer Technology 
Innovation--every three years. These reviews will provide independent 
assessments of the quality of NASA's technology research and program 
planning, whether the research can be performed by universities or 
corporations outside NASA, and how well NASA's technology research 
integrates with customer needs. In each of these program areas, NASA 
will also seek to reduce institutional costs at it field centers so more 
funds can be invested in technology research through openly competed 
NASA research announcements and through university and industry 
partnerships.

    The fourth goal, Commercialize Technology, extends the commercial 
application of NASA technology for economic benefit and improved quality 
of life. By partnering with both aerospace and non-aerospace industry as 
well as academia, the full range of NASA's assets--technological 
expertise, new technologies, and research facilities--are made available 
to help the Nation.

    Academic Programs.--Academic Programs has two components: (1) 
Education Program and (2) Minority University Program. Since the 
creation of NASA, the agency has made a substantial commitment to 
education. NASA's contribution to education has been and is based on the 
Agency's inspiring mission, specialized workforce, close working 
relationship with the research and education community, and unique 
world-class facilities. Based on these attributes, NASA has created a 
comprehensive education program containing a portfolio of activities 
directed toward education at all levels. The guidance for the Education 
Program stated in the NASA Strategic Plan: ``Educational Excellence: We 
involve the educational community in our endeavors to inspire America's 
students, create learning opportunities, and enlighten inquisitive 
minds.'' NASA's Education Program brings students and educators at all 
levels into its missions and its research as participants and partners, 
providing opportunities for a diverse group of students and educators to 
experience first hand involvement with NASA personnel, facilities, and 
research and development activities.

    The Minority University Research Program has a goal to: expand 
NASA's research base by strengthening the research capabilities of 
minority universities and colleges; contribute to the scientific and 
technological workforce; and promote educational excellence. The range 
of activities conducted under this program will continue to capture the 
interest of all students in science and technology, develop talented 
students at the undergraduate and graduate levels, provide research 
opportunities for students and faculty members at NASA centers, and 
strengthen and enhance the research capabilities of the Nation's 
colleges and universities.

    Together, these two components of the Academic Programs budget 
provide guidance for the Agency's interaction with both the formal and 
informal education community.

---------------------------------------------------------------------------

    In 2001, this appropriation provides funding for mission support and 
includes: safety, mission assurance, engineering and advanced concepts 
activities supporting agency programs; salaries and related expenses in 
support of research in NASA field installations; design, repair, 
rehabilitation and modification of institutional facilities and 
construction of new institutional facilities; and other operations 
activities supporting conduct of agency programs.

    Since 2002, NASA has implemented a two-appropriation budget 
(excluding the Inspector General account). The two-appropriation budget 
(Human Space Flight (HSF) and Science, Aeronautics and Technology (SAT)) 
is NASA's first step at transitioning to a full cost budget. While full 
cost will ultimately integrate institutional and programmatic funds into 
a single budget, that integration is done in a step-wise manner, by 
providing for a mission support budget line under each Enterprise and 
eliminating the present mission support appropriation. This initial step 
will begin to recognize, budget, and track direct full time eqivalent 
(FTE) personnel associated at the Enterprise level and then use this FTE 
data to distribute other-than-direct (OTD) institutional costs (Research 
and Program Management and non-programmatic Construction of Facilities) 
using the relative percentages of direct FTE's by Enterprise.

    This means the distribution of the OTD resources takes advantage of 
a basic assumption, to be used prior to the existence of cost and 
service pools, that FTE's are a reasonable relative indicator at the 
Enterprise level of required facility and institutional capabilities. 
Taking this step will help program/project personnel and decision makers 
begin to understand the potential magnitude of institutional funds that 
are associated with each Enterprise in preparation for the day when full 
cost budgeting will distribute these funds most appropriately to the 
project level via the appropriate cost/service pools.

    Beginning in 2002, there is no longer a Mission Support account. 
Institutional costs will be budgeted within HSF and SAT (as discussed 
above) and safety, mission assurance and engineering will be budgeted 
within the HSF account.

    NASA plans to control personnel levels through full time permanent 
(FTP) civil servant positions while continuing to track full time 
equivalent positions, as done in the past. This will allow NASA more 
flexibility in the use of non-permanent positions for short-term 
technical needs as well as co-op and intern programs.

Performance Objectives

    Research and program management.--In 2001, this activity provided 
for the salaries, travel support, other personnel expenses of the entire 
NASA civil service workforce, and includes vital support to the physical 
plant at the Centers and at NASA Headquarters.

    Construction of facilities.--In 2001, this activity provided for 
facility construction activities to preserve NASA's infrastructure and 
enable NASA's missions; environmental compliance and restoration 
activities, design of facilities projects, and advanced planning and 
critical functional leadership activities related to future facilities 
needs. Activities in support of construction projects to repair, 
revitalize and modernize the basic infrastructure and institutional 
facilities at NASA centers will continue with the major focus on 
eliminating safety-related concerns. Increasing attention is being given 
to activities in support of environmental compliance and restoration 
requirements.
