LSST Mirror Turns Blue

Welcome

LSST received its federal construction start in August of 2014. This website supports the LSST Project Office in its construction of the facility.

LSST Mirror Turns Blue

It’s not the frigid cold temperatures being experienced by much of the county this week, but rather a thin coating of polyethylene that has turned the LSST primary/tertiary mirror (M1M3) a vibrant shade of blue. This coating has been applied to protect the mirror as it is prepared for delivery and final acceptance. Formal delivery is expected in early April when the LSST Project will take responsibility for the mirror in its shipping container and move it to a secure facility for storage. The mirror is expected to remain in storage for approximately two years until the operational mirror support cell is fabricated, at which time the mirror and mirror cell can be integrated and tested before being shipped to Chile.

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).
