STS-80 was a Space Shuttle mission flown by Space Shuttle Columbia. The launch was originally scheduled for 31 October 1996, but was delayed to 19 November for several reasons. Likewise, the landing, which was originally scheduled for 5 December, was pushed back to 7 December after bad weather prevented landing for two days. The mission was the longest Shuttle mission ever flown at 17 days, 15 hours, and 53 minutes. Although two spacewalks were planned for the mission, they were both canceled after problems with the airlock hatch prevented astronauts Tom Jones and Tammy Jernigan from exiting the orbiter.
Low Earth OrbitThe Mars 96 spacecraft was launched into Earth orbit, but failed to achieve insertion into Mars cruise trajectory and re-entered the Earth's atmosphere at about 00:45 to 01:30 UT on 17 November 1996 and crashed within a presumed 320 km by 80 km area which includes parts of the Pacific Ocean, Chile, and Bolivia. The cause of the crash is not known.
Heliocentric N/AThe Mars Global Surveyor (MGS) is designed to orbit Mars over a two year period and collect data on the surface morphology, topography, composition, gravity, atmospheric dynamics, and magnetic field. This data will be used to investigate the surface processes, geology, distribution of material, internal properties, evolution of the magnetic field, and the weather and climate of Mars.
Heliocentric N/AThe Ekspress series spacecraft for Data transmission, TV & radio-broadcasting, communications, Internet, video-conference closely resembled the Gals spacecraft and shared a similar spacecraft bus. Ekspress was to replace the widely used Gorizont spacecraft, and plans called for deployments at 13 locations (40 degrees, 53 degrees, 80 degrees, 90 degrees, 96.5 degrees, 99 degrees, 103 degrees, 140 degrees, 145 degrees, 205 degrees, 322.5 degrees, 346 degrees, and 349 degrees, all East longitude) for domestic needs and to support the Intersputnik Telecommunications Association.
