  2. Observatory Systems of Systems OVERVIEW • Goal: Leverage astronomical community’s plan to develop a: • synoptic survey telescope (LSST) • interactive web-based access to massive archival databases (NVO) • world’s 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.

  17. 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
