Construction Progress

February 17, 2017 - New drone images from the summit of Cerro Pachón show the rapid progress of LSST construction. You can see the circular lower enclosure with the telescope pier inside, the elevator shaft, and the (long rectangular) service building. The third image shows white siding going up on the lower enclosure and progress on the foundation for the Auxiliary Telescope. Inside the facilities building windows are appearing, drywall is going up and cable trays are being installed. The summit team has one month to get ready for the start of Dome installation. Telescopes in the background are (L-R) SOAR, and Gemini South. Thanks to LSST Telescope & Site Assembly, Integration, and Verification (AIV) Manager Jacques Sebag for obtaining these pictures during a recent visit. 

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).
