Table Mountain Observatory (TMO) is an astronomical observation facility operated by NASA's Jet Propulsion Laboratory (California Institute of Technology). It is located in Angeles National Forest near Wrightwood, California.[1] Located 63 kilometers (39 mi) north-northeast of Los Angeles, 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.[2]

TMO 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.[3]

Instruments[edit]

Observing with the 0.6m telescope

Former instruments[edit]

  • A 1.25 m (49 in) reflector previously located at Cloudcroft Observatory was acquired in the late 1980s and became operation in the early 1990s.[7][8] It was removed from the TMO web site before June 2003.[9]
  • A 0.4 m (16 in) Ritchey-Chrétien reflector built by RC Optical Systems was attached to an equatorial mount. It was installed in 2003 and removed from the TMO web site before July 2011.[10] It was housed in the dome where the Schmidt camera was previously located.
  • A 0.4 m (16 in) Cassegrain reflector was installed at TMO in 1962.[2] Harvey Mudd College was the main user of this telescope from the 1970s through at least 1991.[8]
  • A 0.27 m (11 in) Schmidt camera owned by JPL operated at TMO from 1985 until at least 1991.[8][11]
  • A 5.5 m (18 ft) millimeter wavelength radio antenna was located at TMO from 1970 until at least 1985.[11]
  • A radio interferometer with dishes of 4.4 m (14 ft) and 3.0 m (9.8 ft) became operational at TMO in 1974.[12]
