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.

Rubin's secondary mirror uncovered for the first time after installation

Seven members of the Rubin Observatory team pose for a group photo beneath the newly revealed reflective secondary mirror. The secondary mirror itself is surrounded by a black light blocking baffle ring. Beyond the light baffle, the far wall of the observatory dome interior is visible as a white wall with many criss crossing teal beams.
Rubin Observatory summit staff removed the protective cover from the secondary mirror on August 20, 2024, revealing the reflective surface while installed on the telescope for the first time. Staff then installed a stray light-blocking baffle, which will reduce glare and other unwanted effects in Rubin images.
