About twice daily, the Hubble Space Telescope radios data to a satellite in the geosynchronous Tracking and Data Relay Satellite System (TDRSS), which then downlinks the science data to one of two 60-foot (18-meter) diameter high-gain microwave antennas located at the White Sands Test Facility in White Sands, New Mexico.

Studying X-ray and gamma-ray objects with Hubble, as well as Chandra and Compton, gives accurate size and positional data. In particular, Hubble's resolution can often discern whether the target is a standalone object, or part of a parent galaxy, and if a bright object is in the nucleus, arms, or halo of a spiral galaxy. Similarly, the smaller ...
While the Hubble Space Telescope of the National Aeronautics and Space Administration (NASA) has collected a large amount of astronomical data, has outlived all expectations, and has been described as one of the space agency's most successful missions, the facility will eventually succumb to the extreme environment of space.

When they did fly again, Galileo would have to compete with high-priority Department of Defense launches, the tracking and data relay satellite system, and the Hubble Space Telescope. By April 1986, it was expected that the Space Shuttles would not fly again before July 1987 at the earliest, and Galileo could not be launched before December 1987.
The first Misty satellite, USA-53, was released by the Space Shuttle Atlantis on mission STS-36 in 1990. The USA-144 satellite, launched on 22 May 1999 by a Titan IVB from Vandenberg Air Force Base may have been a second Misty satellite, [53] or an Enhanced Imaging System spacecraft. The satellites are sometimes identified as KH-12s.
Satellite Tracker - (ProSat) Displays satellite paths 7 days in advance and operates offline until additional days are needed. Compass view of paths as well as 3D earth view. Allows user to input and store satellite radio frequencies while accounting for live doppler shift. [12]
The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by a Space Shuttle in April 1990. It is named after American astronomer Edwin Hubble. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy.
The disaster that engulfed the Space Shuttle Challenger led to a review of the entire space-shuttle program, delaying the launch of the Hubble from 1986 to 1990. Bulkin described the April 24, 1990 launch of the Hubble Space Telescope as "like watching your mother-in-law go over a cliff in your brand-new Cadillac."
