The Aeros-B satellite was built to help scientists study the state and behavior of the upper atmosphere and ionosphere.
The Applications Technology Satellite (ATS) was built to provide good quaility TV signals to small, inexpensive ground receivers.
The Broad Band X-ray Telescope (BBXRT) was flown on the space shuttle Columbia (STS-35) as part of the ASTRO-1 payload.
The Compton Gamma Ray Observatory was the second of NASA's Great Observatories. Compton, at 17 tons, was the heaviest astrophysical payload ever flown at the time of its launch on April 5, 1991 aboard the space shuttle Atlantis. Compton was safely deorbited and re-entered the Earth's atmosphere on June 4, 2000.
The COBE satellite was developed by NASA's Goddard Space Flight Center to measure the diffuse infrared and microwave radiation from the early universe to the limits set by our astrophysical environment. It was launched on November 18, 1989.
The Extreme Ultraviolet Explorer (EUVE), a NASA explorer class satellite mission, was launched on June 7 1992 and it operated till January 31 2001.
America's first artificial satellite.
The Explorer 6 satellite was designed to study trapped radiation of various energies in the Earth's atmospere.
The IUE mission was the world's longest (18.7 years uninterrupted orbital operations) and most productive astronomical space observatory mission.
The first 3 Landsat missions were also known as the Earth Resources Technology Satellite (ERTS) series. Landsat-2 largely carried on the work conducted by Landsat-I; like its predecessor, it far exceeded its design life, sending images until 1982.
The ROSAT mission consisted of an x-ray observatory satellite that carried three instruments.
The SMS-A mission was built to allow scientists to sense meteorological conditions from a fixed location above the Earth.
SNOE re-entered the atmosphere on December 13 2003, after orbiting for 5 years and 290 days.
NASA's Spartan program was based on the idea of a simple, low-cost platform deployed from a space shuttle in orbit for a 2-3 day flight, then recovered and returned to Earth.
Tiros-1 was the first successful weather study satellite.
The Total Ozone Mapping Spectrometer, launched in July 1996 onboard an Earth Probe Satellite (TOMS/EP), continues NASA's long-term daily mapping of the global distribution of the Earth's atmospheric ozone.
The vanguard mission was a small satellite designed to test the launch capabilities of a three-stage launch vehicle and study the effects of the environment on a satellite and its systems in Earth orbit.
