4. May 11, 20064 Astrophysics Division Budget Problems and Issues Budget problems and issues that must be dealt with during this summer’s budget formulation – Additional funding in slip of HST SM4 launch date beyond 12/07 – Level of near term contingency for JWST – Funds required for SOFIA to support final decision on path forward – Additional funds to cover expected GLAST replan – Potential cost growth in Kepler – Decision on future of WISE – Restoration (full or partial) of funds to R+A program – Adjustments to mix within Navigator program (TPF issue) – Direction within Balloon Program on future plan for ULDBs

5. May 11, 20065 Astrophysics Division Budget Principles, Priorities & Constraints (1) General Principles – Follow priorities set by NRC surveys and reports – Support Administration goals and direction In Practice – Incremental budget “solutions” can lead to wrong global solution Best approach is to solve all problems at one time each year (POP) – Slipping current missions not always the right answer Only solves short term budget problems Creates bow wave of funding requirements downstream Increases total mission cost far more than inflation (marching army) Cancellation may be more sensible option – Applying a “tax” across the board not a good approach Spread the pain but weakens all programs Once or twice may have minor impact; eventually has significant impact on all projects Reserve this approach for directed reductions (rescissions, hurricane tax, etc.)

6. May 11, 20066 Astrophysics Division Budget Principles, Priorities & Constraints (2) Priorities – Continue healthy operating missions – Complete and launch missions in development – Provide for the future ( R&A, technology, balloons, concept studies) Constraints – Congressional direction/mandates – Solution must balance each of the 5 years in the budget horizon Currently working on FY08-12 budget Only guaranteed budget is the single year approved by Congress in the Operating Plan Considerations – Mission size/launch frequency – Wavelength – Mission Phase – Long term strategy

11. May 11, 200611 Astrophysics Division Budget Example Hypothetical Issue: Restore15% R&A funding reduction Solution 1: Reduce Beyond Einstein Program funding – Hold budget to the FY06 level for FY07-08 (~ $14M per year) Restores ~10% ($7M) in FY07 and FY08 Restores full 15% starting in FY09 ($11M per year) – Slips first Beyond Einstein mission Solution 2: Apply an across the board “tax” – Approximate 1% reduction to all programs Some programs may be protected (e.g. HST SM4) Solution 3: Restore as part of overall Astrophysics budget solution during FY08-12 POP – Allows more flexible solution space – Solution is part of Division’s overall strategy
