Mirror Lab workers load 51,900 pounds of glass into mirror mold.

The University of Arizona's Steward Observatory Mirror Laboratory is about to cast a new kind of giant optic for a unique wide-field survey telescope, the Large Synoptic Survey Telescope. The telescope will be the widest, fastest, deepest eye of the new digital age.

 Mirror Lab workers will begin loading 51,900 pounds of glass into the mirror mold early today.

The Mirror Lab will cast two mirrors as a single piece of glass for the telescope, known as the LSST, this month. The lab will cast an outer 27-foot-diameter (8.4 meter) primary mirror and an inner 16.5-foot-diameter (5 meter) third mirror in one mold. It is the first time a combined primary and tertiary mirror will be produced on such a large scale.

The LSST will be the world's largest, most powerful wide-angle survey telescope. It will provide time-lapse digital imaging across the entire available night sky every three days, enabling astronomers anywhere simultaneous access to study supernovae, planet-approaching asteroids or comets and other dynamic celestial chance events, and explore the nature of dark matter and dark energy.

Science Collaborations

The LSST will open a new window on the variable sky. Recent surveys have shown the power of variability for studying gravitational lensing, searching for supernovae, determining the physical properties of gamma-ray burst sources, etc. The LSST, with its repeated, wide-area coverage to deep limiting magnitudes will enable the discovery and analysis of rare and exotic objects such as neutron star and black hole binaries; gamma-ray bursts and X-ray flashes, at least some of which apparently mark the deaths of massive stars; AGNs and blazars; and very possibly new classes of transients, such as binary mergers and stellar disruptions by black holes. It is likely that the LSST will detect numerous microlensing events in the local group and perhaps beyond.

AHM August 9-13, 2010

The LSST All Hands Meeting will take place the week of August 9th 2010 at the Ritz-Carlton Dove Mountain 15000 North Secret Springs Drive, Marana, Arizona, 30 miles north of Tucson.

This page will be updated with information as it becomes available, approximately April 1st.

Financial support for Rubin Observatory comes from the National Science Foundation (NSF) through Cooperative Support Agreement No. 1202910, 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.
