The lifter is supported by the crane above the mirror with 54 vacuum pads on the mirror. The pumps connected to the pads (yellow boxes located on the lifter) are on in this picture, creating a vacuum under each pad and securing the mirror to the lifter.

DrupalCon Austin

The LSST web team made its annual trip to DrupalConJune 2-6 with the maturing LSST website redesign project in mind. Drupal is a free, modular, and open source content management framework used by LSST for its websites. DrupalCon, the largest gathering of Drupal developers and users, afforded the LSST web team the opportunity to meet, brainstorm, and share lessons learned with the approximately 3,300 other Drupal users who attended. During the week in Austin, Texas, the team focused on sessions addressing “Frankensites,” accessibility, security, and best practices for upgrading to new Drupal versions.

TMA Contract Officially Signed

August 13, 2014 – The LSST Telescope Mount Assembly (TMA) contract has been signed by AURA and vendor GHESA Ingeniería y Tecnología, S.A (in consortium with ASTURFEITO, S.A.).

Andy Connolly’s TED Talk

In March of 2014, UW astronomer and LSST Simulations Lead Andy Connolly was a featured speaker at the Vancouver, Canada, TED Symposium. He describes LSST when talking about “What’s the Next Window into our Universe?”. This talk is now featured online:

“Big Data is everywhere – even the skies. In an informative talk, astronomer Andrew Connolly shows how large amounts of data are being collected about our universe, recording it in its ever-changing moods. Just how do scientists capture so many images  at scale? It starts with a giant telescope…”

Mirror Nears Completion

The LSST monolithic M1M3 mirror blank approaches completion at the University of Arizona’s Steward Observatory Mirror Lab. The combined primary (M1) and tertiary (M3) surfaces are seen on the left in this image from July 2014 with the red polishing compound highlighting the active polishing zone of M3. In anticipation of completion, the vacuum lifting fixture (right, September 2014) is being assembled to supply suction to lift the mirror off the polishing cell and lower it into the mirror transport box once the polishing is complete. The fixture will then be disassembled and stored locally until it’s time to reinstall the M1M3 for final optical testing in the telescope cell prior to shipment to Chile.

SAC Seeks Input

Now that federal construction on LSST has formally begun, the LSST Project has constituted a Science Advisory Committee (SAC). The committee’s job is to represent the wider scientific community (including the US astronomical community) and to advise LSST Project Director Steve Kahn as decisions are made throughout the LSST construction phase.

New Hires

The LSST Hiring Campaign continues in full force as the project staffs up to meet the demands of the construction effort. Current positions, along with those filled and coming soon, are posted online at www.lsst.org/hiring. The five individuals below have joined the project recently as examples of Top Talent Working in a Team Environment that Inspires Excellence – welcome!

M2 Substrate Relocation

The LSST secondary mirror (M2) substrate has been safely relocated from Harvard University in Cambridge, MA to the Exelis facility in Rochester, NY. The mirror’s trek, which involved the use of a 50-ton internal bridge crane to load the mirror transport box onto a wide-load flatbed truck and a 70-ton external crane to offload it at destination, covered 604 miles in a little over a day. The truck and pilot vehicle departed Harvard at 1 pm on October 20 and arrived in Rochester at 3 pm on October 21. Subsequently, Exelis personnel have disassembled the transport box and thoroughly inspected the substrate.

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 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.
