5. Progress on Recommendations

6. Status of Decadal Survey Recommendations Small Initiatives: –National Virtual Observatory (NVO) - Framework development funded; discussion with NASA planning long-term support through joint solicitation; Cyber funds in ’06 and beyond? –Laboratory Astrophysics program - funded in grants program, strongly represented in FY2004 proposals and awards; substantial co- funding with chemistry and physics divisions –Theory support – MPS Theory Workshop; science opportunities, modes of support, education and training issues - ~30% of grants are for theory, no need for separate theory program in AST

9. The ATST Project The Advanced Technology Solar Telescope

10. Improvements over current state of the art: Resolution – ~7X improvement Light grasp – 10X improvement (solar physics is actually photon starved in some experiments) Technical Specifications: 4-m, off-axis Gregorian (all reflective), alt-az mount. Integrated adaptive optics. Hybrid enclosure with thermal control and dust mitigation. Wavelength sensitivity from 0.3-28 microns (near- UV through thermal infrared). Field of view: 3 arcminutes (5 arcminute goal). Angular resolution < 0.03 arcsecond. Polarization accuracy < 0.01%. ATST will be the world’s flagship facility for ground-based solar physics observation and the first large US solar telescope constructed in the past 30 years. The Telescope

11. Recent and Upcoming Milestones A comprehensive and very successful conceptual design review held on August 25-28, 2003. Construction proposal under review. A set of preliminary design reviews will be held in late 2004 – early 2005, culminating in a systems review by late winter of 2005. Final site selection: Haleakala with La Palma as back-up. Planning for the environmental impact study has begun. RFP will go out ASAP. Note: this is a necessary component of the design process since final design depends on the details of the site.

12. Marching toward MREFC ATST team had planned aggressively for an FY06 start of construction. This will not happen. Additional funding will be required to pay marching army and produce final design (note that current MREFC rules preclude funding design from MREFC). AST will fund through FY06 (FY07). The next steps:  ATST and AST craft development plan for FY05-6.  Site selection complete – contract for environmental impact study  Preliminary design reviews.  Bring to MREFC panel in March 2005.  Attempt to address critical path items – early procurement of primary mirror.  Let contracts for final design to design and engineering firms.  Complete Project Execution Plan.  Final design review in early 2006.  Construction begins in fall of 2006/2007.

13. Readiness – Second Rank Criteria  Impact on scientific advances in related fields considering portfolio balance? In the opinion of AST, the ATST Project is ready for consideration for promotion to “ready” status by the MREFC panel and the NSB. Second Rank Criteria endorsed by MPS Advisory Committee  Opportunities to serve the needs of researchers in multiple fields or multi- disciplinary research?  Commitments from other agencies or countries?  Potential for education and workforce development?  Readiness for further development and construction?
