Opening a Window of Discovery on the Dynamic Universe

Surrogate Mirror

April 2017

The LSST secondary mirror (M2) system has completed another big milestone, with successful demonstration of closed-loop mirror control. The Harris team accomplished this using the aluminum surrogate mirror integrated into the cell assembly.  Meanwhile, the mirror substrate is being prepared for its “first light optical test” in July at Harris in Rochester, NY, with the successful bonding of all actuator pads.

LSST Project / NSF / AURA

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.
NSF and DOE will continue to support LSST in its Operations phase. They will also provide support for scientific research with LSST data.
