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


June 21, 2018 – Last week’s SPIE meeting on Astronomical Telescopes and Instrumentation in Austin, TX, gave LSST team members a chance to share exciting construction progress and learn from colleagues working on other projects and related technologies.  Over the six-day meeting, there were 20 LSST-authored posters, 16 oral presentations plus 2 invited talks, one on LSST Construction Status (V. Krabbendam) and another on the LSST Science Platform (F. Economou).  Deputy Director Beth Willman’s plenary talk on LSST Construction Progress and Scientific Opportunities is available here.  

Several LSST vendors had booths on the exhibit floor.  Ball Aerospace was showing a scale model of the LSST L1-L2 camera lens assembly and Teledyne e2v, maker of half the LSST sensors, brought one to show.  Other vendors included Asturfeito, builders of the Telescope 

Mount Assembly seen in this video, our Dome vendor EIE, as well as MagicDraw, creator of the system modeling tool used throughout the project.

At the time of SPIE 2020 in Japan, LSST will be experiencing engineering first light – providing lots of progress to share at this always exciting meeting!

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.
