LSST Mirror Lifted

30 Octubre 2008

The 8.4-meter mirror blank for the Large Synoptic Survey Telescope (LSST) has been successfully lifted from the furnace hearth at the Steward Observatory Mirror Lab, installed into a turning ring, and tilted to a vertical position. It is now ready for core cleanout, which will reduce its mass from 46,500 kg to 16,600 kg. The mirror is scheduled to be completed in January 2012, and will be the largest two-surface optical mirror ever made from a single substrate.
