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
