LSST Status
Kirk GilmoreLSST Camera ScientistStanford/SLAC/KIPAC
LSST Science Requirements focus on 4 Representative and Divergent
Programs
LSST enables multiple investigations into our understanding of the universe
Dark Energy-Dark Matter Exploring our Solar System
LSST will find 90% of hazardous NEOs
down to 140 m in 10 yrs
“Movie” of the Universe: time domain Mapping the Milky Way
LSST will map the rich and
complex structure of our
Galaxy.

Ultra-large Data Management: LSST
* 100+ petabyte system* Multi-dimensional data set* Large user base ranging from professional astronomers to general public. Complex
analytics* SLAC is responsible for delivering the LSST database and data access system
* SciDB - a new open source data management system for data-intensive scientific analytics
– Design led by world-class database researchers • Mike Stonebraker, David DeWitt
* SLAC's involvement– Actively helped define SciDB– Coordinates input from all sciences
* SLAC has a chance to make big positive impact on complex scientific analytics and beyond

Conclusions
* LSST Camera R&D progressing well toward NSF full LSST PDR, scheduled for early 2009.
* A contemporaneous DOE CD-1 would keep the project on track to enable first light in 2016.
* Significant growth in this program is envisioned beginning if FY10, with LSST replacing GLAST/Fermi as the major development effort in particle astrophysics and cosmology at SLAC.
