M2 Optical Fabrication Contract Awarded to ITT Exelis

July 12, 2013 -- ITT Exelis has been awarded the optical fabrication contract for LSST’s 3.5m secondary mirror assembly ( The two-phase contract was awarded by AURA on behalf of the LSST project. The first phase supports vendor-specific engineering design activities targeted at risk reduction. The second phase includes the optical fabrication, testing, and integration of the finished mirror into the LSST-supplied M2 cell assembly.

LSST Mirror Status - Thinking Outside/Inside the Box

The unique LSST M1/M3 mirror surfaces are nearing perfection. Both mirror surfaces are being carefully polished and optically tested with completion anticipated by the end of December 2013. Testing has transitioned from the realm of mechanical measurement to optical measurement as the remaining deviations from the mirror’s perfect smooth shape are now on the scale of nanometers instead of microns.

DM Awarded XSEDE Computing Resource Allocation

Friday June 21, 2013 - LSST Data Management was awarded a computing resource allocation from the Extreme Science and Engineering Discovery Environment (XSEDE) in June 2013.  This award of 530,000 compute service units and 148 terabytes of storage is a renewal of previous awards that LSST has been granted by XSEDE.  It allows DM to continue the larger scale runs associated with the sequence of Data Challenges and large-scale middleware and infrastructure tests that are necessary in preparation for the Construction phase of LSST.  This allocation will be in effect fo

Final Design Review - Save the Date

The Final Design Review (FDR) for the LSST project has been scheduled for the week of October 21, 2013 in Tucson, Arizona.  This review must be completed successfully before the National Science Foundation (NSF) can release funds to start construction.  And, of course, Congress also must appropriate the funds before the NSF can release them.  We’re expecting a review format and schedule (Monday noon to Friday noon) much like the August 2011 NSF Preliminary Design Review.

Inaugural Meeting of LSST@Illinois

LSST Institutional Members from Illinois met at Argonne National Laboratory on May 30 for the inaugural meeting of LSST@Illinois.  Organized by Salman Habib, the meeting was attended by about 40 individuals from Adler Planetarium, Argonne, Fermilab, University of Illinois/NCSA and Northwestern University.  Many in the group "bonded" previously at a Washington, DC LSST Board Meeting and decided to continue their discussion of current projects, what each institution would individually like to get out of LSST, and how they can work together to help LSST@Il

LSST Represents AAS in May 2013 CNSF Exhibit

May 10, 2013

LSST exhibited at the 19th Annual Coalition for National Science Funding (CNSF) reception in the Rayburn House Office Building on May 7, 2013. The American Astronomical Society is a member of CNSF and sponsored LSST to participate in this year’s event with the theme: Investments in STEM Research and Education: Fueling American Innovation.

Chuck Claver Receives AURA Technology / Innovation Award

AURA announced LSST Systems Scientist Chuck Claver as one of the 2013 recipients of its Technology / Innovation Award (see He is being recognized for his outstanding contribution to LSST as Project Systems Engineer over the previous five years. For the complete story, visit     



Steve Kahn Named LSST Project Director

Washington March 12, 2013 -- AURA announced today that Dr. Steven M. Kahn will assume the role of Director of the Large Synoptic Survey Telescope (LSST) Project effective July 1, 2013. Dr. Kahn will succeed Dr. Sidney C. Wolff and retain his current affiliation with SLAC and Stanford.

LSST AAS 221 Posters Online

11 LSST posters were put up (on time) at the Long Beach AAS Meeting and have been posted here for viewing or download. Most posters then went on to SLAC for the DESC meeting.  Many thanks to the poster authors and production team for yet another successful LSST poster session.


Financial support for Rubin Observatory 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 Rubin Observatory 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 the Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.
