Table Mountain Observatory

Table Mountain Observatory (TMO) is an astronomical observation facility operated by NASA’s Jet Propulsion Laboratory (California Institute of Technology).

TMO is part of JPL’s Table Mountain Facility (TMF). The larger site hosts a number of non-astronomical projects. The site was first used by the Smithsonian Institution in 1924, which conducted atmospheric, solar, and astronomical observations for many years. JPL took over the lease in 1962. The observatory conducts high-precision astrometric observations to support NASA and international spacecraft mission navigation, confirmation and recovery of near-Earth objects such as comets and asteroids that may potentially impact the Earth, and technology development.
