Major milestone: The first of 21 "science rafts" for the 3.2-gigapixel Large Synoptic Survey Telescope (LSST) camera has arrived from Brookhaven National Lab this week. The rafts are arrays of nine imaging sensors, or CCDs, each with 4K-by-4K pixels. The LSST camera will be the largest digital camera ever built for astronomy. It will provide researchers with the widest, deepest and fastest views of the night sky for unprecedented studies of the Milky Way, the solar system, dark matter, dark energy, and much more. SLAC is assembling and testing the camera from parts built by a large collaboration of labs and universities.
