2. Astro 2010 The Next Decadal Survey in Astronomy & Astrophysics Board on Physics and Astronomy (lead) –Anneila Sargent, Chair –Jon Bagger, Executive Committee –Don Shapero, Executive Officer Space Studies Board –Len Fisk, Chair –Marcia Smith, Executive Officer Committee on Astronomy and Astrophysics –Meg Urry (BPA) & Chuck Bennett (SSB), co-chairs –2-year planning process for Astro 2010 –CAA going into hibernation (during survey)

3. Astro 2010 Current Status Internal proposal at NRC is approved; planning can proceed April 28, 2007 meeting under auspices of BPA and SSB –BPA, SSB astronomers plus several others –How to adjust survey model to changed circumstances? –Developed guiding principles for survey Proposal submitted to NASA, NSF, DOE Survey will not start (and committee will not be selected) until it is funded by agencies –Hope to start in early 2008

4. Astro 2010 Guiding Principles (1) Community involvement –Already town meetings at AAS, APS –Will be extensive, on the Bahcall model Organization of panels –Re science v., open issue Evaluating cost and technical readiness –BEPAC model? Independent assessment Unrealized projects - include in prioritization

5. Astro 2010 Guiding Principles (2) International community –Cooperation on big projects? Scientific scope –E.g., include Beyond Einstein science –Other boundaries? Robustness to changing circumstances (e.g., cost growth, technical issues, changing science) –“Decision rules” –Mid-term assessments?

6. Astro 2010 Guiding Principles (3) Makeup of committee –Addition of other experts in science, policy, etc. –Could help with friendly critique and credibility Send nominations, comments, suggestions to astro2010@nas.edu
