The U.S. National Science Foundation (NSF) and the U.S. Department of Energy (DOE) Office of Science will support Rubin Observatory in its operations phase to carry out the Legacy Survey of Space and Time. They will also provide support for scientific research with the data. During operations, NSF funding is managed by the Association of Universities for Research in Astronomy (AURA) under a cooperative agreement with NSF, and DOE funding is managed by SLAC National Accelerator Laboratory (SLAC), under contract by DOE. Rubin Observatory is operated by NSF NOIRLab and SLAC.

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.

The DOE Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.

The coated 8.4-meter mirror

View of Rubin’s 8.4-meter mirror with its reflective coating applied. The mirror is positioned in front of and just below the similarly sized round silver coating chamber. Six people in white coveralls, haircovers, and face masks are standing above and behind the mirror, raising their hands in the air, 3 on the left side of the mirror, and 3 on the right. One similarly dressed person is popping out of the hole in the center of the mirror.
Group photo with Rubin Observatory’s 8.4-meter combined primary/tertiary mirror, right after it was coated with protected silver in April 2024. The reflective coating was applied using the observatory’s onsite coating chamber, which will also be used to re-coat the mirror as necessary during Rubin’s 10-year Legacy Survey of Space and Time. L-R: Juan Lopez Toro, Mario Rivera, Claudio Araya Cortés, Tomislav Vučina (in the center of the mirror), Franco Colleoni, Sandra Romero and Mauricio Araya.
