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.

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
