Advancing GSMT SWG Recommendations: AURA’s Proposal to the NSF

  • Stephen E. Strom

  • AURA New Initiatives Office

  • Presented to the GSMT SWG

  • 12 February, 2004


GSMT SWG Conclusions (June, 2003)

  • “In order to reap the enormous potential synergy between the James Webb Space Telescope (JWST) and a 20-m to 30-m telescope, it is essential to initiate major design and technology development efforts now to ensure that facility operations coincide with the early JWST era.”

  • “Federal investment now in a major technology development program targeted at key areas can advance multiple design programs, and will ensure a strong public voice at all stages in the development of next-generation telescopes.”



AURA’s Initial Response

  • Partner with Caltech, UC and ACURA to carry out the design of a 30m telescope (TMT)

    • Complete Preliminary Design by Q4 2007
  • Request NSF funds ($35M ) for technology developments critical to TMT and essential to other ELTs

    • Site evaluation
    • Detectors
    • AO components
    • Instrument components (e.g. gratings)
    • High performance durable coatings
  • Engage the community via participation in

  • NSF investment results in community time on TMT



AURA’s New Approach

  • Goal:

    • Advance the design of TMT and one or more other US ELTs programs so that performance, cost, schedule and risk of differing approaches can be assessed
  • Provide $17.5M for TMT partnership

    • NSF dollars leveraged 3:1 (assuming ACURA funded by CfI)
  • Provide comparable funds for other ELT programs



Investment in TMT

  • Responds directly to AASC recommendations

  • The community will receive observing time in proportion to the public investment

  • Technology developments will be transparent

    • Reported to other groups
    • Published openly
  • NSF-supported technology developments will be competed openly so as to engage the broader community

  • AURA will be represented at all levels in the project

    • The community will have a ‘seat at the table’ throughout the Design and Development Phase
  •  



Investment in Other ELT Programs

  • Support technology development and design efforts needed to advance one or more ELT concepts

  • AURA will request letters of intent outlining a coherent plan for advancing an ELT concept

  • Letters would need to outline

    • Current and future private/state matching funds
    • Total cost of the proposed Design and Development effort
    • Proposed mechanisms for making technology developments transparent
    • Proposed mechanisms for incorporating community input into decision making
    • Proposed mechanisms for engaging the broader community in technology developments


Advantages of the New Approach

  • Directly responsive to SWG recommendations

  • AURA will ensure that NSF investments in TMT and other efforts are synergistic and complementary

  • US community is engaged in ELT efforts and will receive time in proportion to federal investment in all ELTs

  • Open dialog between projects benefits all and leaves open a ‘convergence path’

  • Technology investment in ELT programs will result in significant gains for existing telescopes



AURA MOU with ESO

  • In fall, 2003 AURA signed a Memorandum of Understanding with ESO

    • Establishes multiple working groups
  • AURA-NIO will work with ESO to align investments in:

    • Site evaluation
    • AO system and component developments
    • SiC evaluation
    • Detector development
  • Investments are intended to accelerate design efforts in the US and in Europe

    • Explore multiple approaches to technically challenging problems
    • Develop multiple (competitive) vendors


Potential for International Collaboration

  • AURA’s MOU with ESO opens the path to collaboration on a large, international ELT

  • AURA welcomes collaboration with other international groups

    • Accelerate both US and international efforts by focussing funds on technically challenging systems and components
    • Builds relationships from which partnerships can develop naturally
