LSST is a multi-agency project

NSF / DOE coordinated – MOU established

National Science Board: NSF Director can move LSST forward

DOE has assigned SLAC National Accelerator Center to build the Camera

LSST is now an independent AURA Center for construction

LSST Center and NOAO Center have MOU for specific cooperation

Project is organized and preparing for July 2014 construction

New C.A for Design and Development FY13- FY15

Budget set: Requesting $466M NSF, $160M DOE, $36M Private

Schedule duration is 7 years 3 months from NSF construction start

The LSST Project continues to progress steadily in anticipation of a July 2014 formal construction start

LSST was ASTO 2010 highest ranked new ground based facility – We are preparing for a 2014 Start
