Opening a Window of Discovery on the Dynamic Universe

LSST High Fire Event

The LSST primary/tertiary mirror experienced a successful High Fire over the weekend of March 28 & 29th, 2008, reaching a peak temperature of approximately 1165∫C (2125∫F). (See this video taken inside the oven over high fire). This event is the critical first step in fabricating the key optical components of the LSST, a unique wide-field survey telescope. The LSST mirror will now anneal and cool gradually to room temperature over the next 100 days in the slowly rotating oven of the UA Steward Observatory Mirror Lab, and will be removed for grinding and polishing in mid-August. More images are to be added as time allows.

Financial support for LSST comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded LSST Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA).  The DOE-funded effort to build the LSST camera is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
