Subject: Successful LSST Milestone of transition of mirror blank from furnace hearth to vertical position
Yesterday the cast 8.4 meter LSST mirror blank was successfully lifted from the furnace hearth, put into the turning ring and tilted to the vertical position. The finished light weighted mirror will be 16,600 kg with the thickest outside edge height of 0.92 meters ever made at the Mirror Lab. Once completed this will be the largest two surface optical mirror made from one substrate in the world. The mirror is schedule to be completed in January 2012. See the pictures in the attached file.
This is a significant milestone for this project, the Mirror Lab and Steward Observatory. Thanks to all the staff that have contributed to successfully making this accomplishment happen.
