Fundamental Physics at NASA
• “Laboratory” fundamental physics within the Astrophysics Division: The fundamental issues
• Difficult times: Budget, earmarks• Advisory bodies• The Roadmap process: The nose of the camel…• Summary
How Can Laboratory Fundamental Physics Become a Priority within Astrophysics?
• Context:• Fixed funding: money for LFP comes at expense of other existing programs• Large (strategic) missions: Must be in the Decadal Survey, which establishes
national priorities across agencies, and subsequently the NASA Roadmap.• NRC’s Board of Physics and Astronomy (BPS) and the Space Studies Board (SSB)
supports the Astronomy and Astrophysics Survey Committee (AASC)• Panel Reports to the BPS/SSB provide input to AASC
• Small mission opportunities: Explorer Program (WMAP success; STEP made finalist list)
• Research and Analysis: Reduced funding, although LFP does receive modest support (e.g. APOLLO, in cooperation with the NSF); balloon missions.
• International Space Station: No longer a NASA decision; the Administration has decided to use the US share of the ISS only for those life science studies required for exploration.
• Entry Points:• Decadal Survey• Advisory bodies (NAC, ApS, AAAC)• SMD Roadmap

Current Budgetary Issues at NASA
• Unanticipated costs within the Shuttle and International Space Station programs required the Administrator to reduce the growth in the Science Mission Directorate funding levels by ~$3B over the next five years.
• SMD now sees 1.5% growth in FY07, followed by 1% growth in later years.
• Within the Astrophysics Division, cost increases in JWST, GLAST, and HST SM4 have serious impact on other, later missions: • NuSTAR is cancelled.• SOFIA has undergone review (budget zeroed out for FY07 and
beyond); fate TBD.• Terrestrial Planet Finder (TPF) zeroed out for FY07 and beyond.• Beyond Einstein Program severely cut.• R&A budget cut by 15% for FY07 and beyond. (This is being
reconsidered following response from the science community.)

Astronomy and Astrophysics in the New Millennium
The report of the Astronomy and Astrophysics Survey Committee (AASC), Astronomy and Astrophysics in the New Millenium, contains recommendations in priority order for new initiatives to realize the science goals of the field. It is the most recent in a series of surveys that are carried out once every 10 years.
In preparing the New Millennium report, the AASC made use of a series of panel reports that address various aspects of ground- and space-based astronomy and astrophysics. These reports provide in-depth technical detail.

3. Astronomy and Astrophysics Advisory Committee (AAAC)
• Congress in 2002 mandates establishment of Astronomy and Astrophysics Advisory Committee (AAAC) to oversee coordination of A&A programs between NASA, the NSF, and DOE. This is an official advisory body to the Government, operating under FACA law.
• Oversight by the Office of Science and Technology Policy, whose role in the Executive Office of the President includes coordination of interagency activities.
• The AAAC has commissioned a number of task groups:• Task Force for Cosmic Microwave Background Research• Dark Energy Task Force• Dark Matter Scientific Assessment Group
• Chaired by Garth Illingworth, UC Santa Cruz
As established in SEC. 23 of P.L. 107-368 (the National Science FoundationAuthorization Act of 2002) and amended by SEC. 5 of P.L. 108-423 (the Department of Energy High-End Computing Revitalization Act of 2004):
ASTRONOMY AND ASTROPHYSICS ADVISORY COMMITTEE
(a) Establishment.—The Foundation, the National Aeronautics and Space Administration, and the
Department of Energy shall jointly establish an Astronomy and Astrophysics Advisory Committee (in this
section referred to as the “Advisory Committee”).
(b) Duties.—The Advisory Committee shall—
(1) assess, and make recommendations regarding, the coordination of astronomy and astrophysics
programs of the Foundation, the National Aeronautics and Space Administration, and the Department of
Energy;
(2) assess, and make recommendations regarding, the status of the activities of the Foundation, the
National Aeronautics and Space Administration, and the Department of Energy as they relate to the
recommendations contained in the National Research Council's 2001 report entitled “Astronomy and
Astrophysics in the New Millennium”, and the recommendations contained in subsequent National
Research Council reports of a similar nature; and
(3) not later than March 15 of each year, transmit a report to the Director, the Administrator of the
National Aeronautics and Space Administration, the Secretary of Energy, the Committee on Science of
the House of Representatives, the Committee on Commerce, Science, and Transportation of the
Senate, and the Committee on Health, Education, Labor, and Pensions of the Senate on the Advisory
Committee's findings and recommendations under paragraphs (1) and (2).
Congressional Charter for the AAAC
Task Force for CMB Research (TFCR)
• The AAAC in 2004 establishes a Task Force for CMB Research: “The Task Force has been asked to provide an ordered program of preliminary observations and technology development ultimately leading to a possible space mission post WMAP and PLANCK.”
• TFCR report (2005) outlines scientific and technology pathway to an ultimate space-based CMBPol mission. (Available at http://www.nsf.gov/mps/ast/tfcr_final_report.pdf)
• Most importantly: The TFCR establishes a unified voice for the U.S. CMB community which is heard by Congress, NASA, and the White House (Office of Science and Technology Policy, Office of Management and Budget)
(From a talk at the CMB and Physics of the Early Universe Conference, April 22, 2006)
4. Strategic Planning and Roadmap: 2001-2003
• Each Theme within the Division had its own subcommittee (under the Space Science Advisory Committee)
• Triennial theme roadmaps produced by “roadmap committees” composed of community and subcommittee members, with agency oversight.
• Theme roadmaps used as input to the Space Science strategic plan, which in turn informed the Agency Strategic Plan.

Summary
• Opportunities exist for doing some types of laboratory fundamental physics experiments in space, but not at the strategic mission level.
• Flat funding levels for SMD science means that addition of new program elements will displace others.
• Scientific priorities are established by the community through NAS/NRC surveys and federal advisory committees. Interagency adoption of common, coordinated goals adds stability and visibility to programs.
• Small, incoherent communities have small influence; a united fundamental physics community is essential. Consider possible avenues to developing a strong science case (national strategic case?), prioritizing, and building a representative body.
• Jean Clavel’s talk on ESA’s Fundamental Physics program; proposal pressure works.
