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.[3][2] 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.[4]
More than 260 minor planets were discovered at TMO, often referred to as "Wrightwood" the
Minor Planet Center and credited to several astronomers, most notably to
James Young, but also to other astronomers such as
Jack B. Child,
Greg Fisch,
A. Grigsby,
D. Mayes, and
Mallory Vale. The MPC also directly credits TMO with the discovery of one numbered main-belt asteroid (see table).
The 1.02 m (40 in) Pomona College Telescope is a
Cassegrain reflector built at
Pomona College. It first became operational in 1985, and had new mirrors installed in 1996.[5][6]
A 1.25 m (49 in) reflector previously located at
Cloudcroft Observatory was acquired in the late 1980s and became operational in the early 1990s.[9][10] It was removed from the TMO web site before June 2003.[11]
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.[12] 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.[3]Harvey Mudd College was the main user of this telescope from the 1970s through at least 1991.[10]
A 0.27 m (11 in)
Schmidt camera owned by JPL operated at TMO from 1985 until at least 1991.[10][13]
A 5.5 m (18 ft)
millimeter wavelength radio antenna was located at TMO from 1970 until at least 1985.[13]
A radio interferometer with dishes of 4.4 m (14 ft) and 3.0 m (9.8 ft) became operational at TMO in 1974.[14]
