  1. AAAC Meeting February, 2007

  2. New GSMT Role NSF has asked that AURA/NOAO act as NSF’s "Program Manager" for the GSMT Technology development effort at a national level in a manner similar to the role played by NASA’s major Centers for the development and operations of various space missions.

  3. AURA/NOAO Role Cont. • Assure that the national needs are understood, and subscribed to, by both TMT and GMT in any public/private partnership for GSMT.  This implies: • Establish and run a national community Science Working Group • Establish and maintain the national Design Reference Mission (DRM) to set scientific performance expectations for candidate designs • Provide an independent evaluation of the community operational needs, costs, and scientific sociology of a GSMT – then leading the community in understanding the implications of these for both a GSMT and the necessary underlying instrumental and human resource capability. • AURA/NOAO will advise NSF on options for international collaboration at a governmental level • NOAO will be the NSF/national presence in any eventual partnership that operates the GSMT. 

  4. AURA/NOAO Role Cont. • Advise NSF about engineering design performance necessary to respond to the DRM and the technical progress of both projects; this should not be interpreted as AURA/NOAO holding independent reviews of either project. • Perhaps provide certain technical services or advice to each project on an equal footing and with funding from the project • Assure a healthy scientific enterprise in the GSMT era. In this regard, AURA/NOAO should lead in defining “the system”, being certain that it addresses an appropriate range of apertures, suite of instrumentation, and utilization of existing non-federal facilities where available.

  5. AURA/NOAO Role Cont. • As recommended by the Senior Review, promote the development of both TMT and GMT at a pace that recognizes the timescales of the MREFC and federal budget processes • Identify areas of commonality or overlap in technology with a view towards optimizing federal and private budgetary commitments • Carry out any appropriate independent technology efforts of importance to both programs. • Advise NSF on possible alternatives to a competitive down-select

  6. AURA/NOAO Role In order to respond to the new role as defined by NSF, AURA/NOAO is restructuring its existing relationships with both projects, withdrawing from any direct partnership participation, and establishing symmetric interfaces with both projects. AURA, NSF, TMT, and GMT are in active discussion about the necessary means and timescales to address any previous imbalances in support for the two projects.

  7. GSMT Development PlanTwo Paths Forward • Full MREFC Construction Path • A three year process • High bar for justification • Operations support • Public Observer interface • One of two telescopes?

  8. GSMT Design Reference MissionEarly 2008 • AURA will work with the GSMT Science Working Group to develop a national Design Reference Mission (DRM) • Quantify performance vs. aperture. • Set scientific expectations for candidate designs traceable to the science goals articulated by the Decadal Survey and the science case that has evolved since then • It will comprise not only the large survey like projects, but would address the nature and level of PI-class projects as well as the role and value archival research. • This Design Reference mission will be reviewed on an annual basis thereafter and is expected to evolve as the community increases its engagement in potential GSMT science.

  9. Pre Decadal Survey AssessmentMid 2009 • AURA will work with the GSMT Science Working Group and the two projects to carry out a full assessment of • Community operational needs including number of nights for known key science projects • Telescope construction costs • Instrumentation costs • The scope and cost of operations that will ensure broad community access for observing and accessing the data. • The results of this assessment will provide a general framework for the Decadal Survey to judge the priority of GSMT.
