Vera C. Rubin Observatory, as a Federal Government funded project, is operating in compliance with the
Presidential Executive Order on Ensuring Adequate COVID Safety Protocols for Federal Contractors.
Rubin Observatory will undertake a thorough exploration of our Solar System with two goals in mind: learning how it originally formed, and protecting Earth from hazardous, near-flying asteroids.
Discovering the origin of the Solar System requires a thorough census, but identifying objects in the outer solar system is challenging. Despite the difficulty, the effort is worth it; gaining a detailed understanding of that region of rocks and dust beyond Neptune could not only clarify the formation history of our solar system, but could point the way to how other systems may form and how star formation in general proceeds.
Protecting the Earth from a possible asteroid impact is not strictly a scientific question but it bears extraordinary importance for life on Earth. While the frequency of near-Earth object (NEO) impacts is exceptionally low, the damage they can cause is immense. A 100-meter diameter asteroid impact would be equivalent to 1600 megatons of TNT—in an ocean basin, the resulting tsunami could devastate coastal margins.
Frequency of occurrence may be low but our ability to predict such events using available technology is higher than for any other form of natural disaster. A recent national Research Council report titled "Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies" found that Rubin Observatory is the most cost-effective way of surveying the most likely and potentially most damaging Earth-threatening objects.
In addition to dark energy and matter, the Milky Way mapping and transient Universe, mapping the Solar System is one of the four key scientific design drivers, with emphasis on efficiently detecting potentially hazardous asteroids (PHAs). Rubin Observatory will make uniquely powerful contributions to the study of small bodies throughout the Solar System, identifying and characterizing 10 to 100 times more objects than are currently known. With these exquisite orbital, color and photometric variability measurements, we will be able to improve models of how our Solar System formed and how it has evolved over time. The latest publication about Rubin Observatory capabilities for enabling Solar System science is Jones et al. (2015)

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.
