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 Rubin Observatory primary mirror cell is suspended beneath the telescope mount, in the process of being installed. A person in an orange construction vest and white hard hat stands slightly to the right, facing the mirror cell. The cell itself is as tall as the person, and four times as wide as the person is tall. On top of the cell is a thick black disk that replicates the dimensions and mass of the 8.4-meter primary mirror. The black disk is just below a similarly sized opening in the telescope mount base, which is a large, thick teal steel structure that the heavy mirror will be bolted to.
The summit team installed the "M1M3 cell and surrogate assembly"—which refers to the steel structure that supports the primary mirror (the cell), with a stand-in for the mirror (the surrogate) attached—to the telescope mount in April 2023
