3.2 billion pixel LSST camera project gets DOE "Critical Decision 1" approval

April 24, 2012
Menlo Park, CA--The Large Synoptic Survey Telescope (LSST) camera received "Critical Decision 1" approval by the DOE to move into the next stage of the project.

Menlo Park, CA--The Large Synoptic Survey Telescope (LSST) cameraa 3.2 billion-pixel digital camera designed by the SLAC National Accelerator Laboratory that will capture the widest, fastest, and deepest view of the night sky ever observedreceived "Critical Decision 1" approval by the U.S. Department of Energy (DOE) to move into the next stage of the project. If all continues as planned, construction on the telescope will begin in 2014. Preliminary work has already started on LSST's 8.4 m primary mirror and its final site atop Cerro Pachón in northern Chile.

According to SLAC, The LSST will survey the entire visible sky every week, creating an unprecedented public archive of data--about 6 million gigabytes per year, the equivalent of shooting roughly 800,000 images with a regular eight-megapixel digital camera every night, but of much higher quality and scientific value. The data will help answer critical questions about the nature of dark energy and dark matter and aid studies of near-Earth asteroids, the structure of our galaxy, and many other areas of astronomy and fundamental physics.

Now that the LSST camera has passed Critical Decision 1, the project begins a detailed engineering design, schedule, and budget phase. While the DOE funds the design and construction of the camera, the full cost and logistics of the new telescope are being shared by the DOE and the National Science Foundation, as well as a large partnership of public and private organizations in the United States and abroad.

"With 189 sensors and over 3 tons of components that have to be packed into an extremely tight space, you can imagine this is a very complex instrument," said Nadine Kurita, the project manager for the LSST camera at SLAC.

"Not only should LSST revolutionize our understanding of the universe, its contents and the laws that govern its behavior, but it will also transform the way all of us, from kindergarteners to professional astrophysicists, use telescopes," said Tony Tyson, LSST director and a professor of physics at the University of California, Davis. "These are exciting times!"
