Observatory Systems of Systems OVERVIEW
  • Goal
  • Leverage astronomical communitys plan to develop
    a
  • synoptic survey telescope (LSST)
  • interactive web-based access to massive
    archival databases (NVO)
  • worlds premiere observation site and largest
    in-place telescope investment (Mauna Kea)
  • wide-band remote access to telescopes,
    computing centers, and databases (Internet2)
  • state-of-the-art high performance computing
    center (MHPCC)
  • into a new model of a system-of-systems
    observatory that would generate a dramatic
    change in both
  • how observational astronomy is conducted, and
  • what we understand of our universe.
  • Request
  • 5M in FY-02 to provide developmental funding
    to capture a 200M out-year program for
    Hawaii-based organizations.
  • FY-03 and 04 needed funding would be
    approximately 10M each year to bring the
    initiative to fruition.

Observatory Systems of Systems New Approach to
Astronomy
  • in the past, exploratory efforts in astronomy
    were constrained by the need to carefully select
    small samples, we can now imagine exploiting the
    revolution in computing and networking to
  • - discover patterns revealed from analysis of
    statistically rich and unbiased image and/or
    catalog databases and from application of
    advanced visualization tools and,
  • - deepen our understanding of complex
    astrophysical systems through sophisticated
    numerical simulations with the use of advanced
    statistical methods
  • erase old barriers of time and distance in
    carrying out modern astronomical observations
