LSST Mirror Arrives at Cerro Pachón

14 May 2019

The 8.4m-diameter primary mirror of the Large Synoptic Survey Telescope (LSST) has reached its home at Cerro Pachón in Chile. Earlier this month, the mirror reached the port at Coquimbo, where it was loaded onto a 72-wheeled transport vehicle for the trip to the summit. The trip included passage through the tunnel at Puclaro Dam, with just inches to spare on either side. In a survey set to begin in 2022, LSST will scan the entire visible sky every few nights for 10 years, opening a new window on the changing Universe.
