1Observatory System of Systems
2Observatory 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.

17Observatory 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
