TSS-1
A number of space tethers have been deployed in space missions. Tether satellites can be used for various purposes including research into tether propulsion, Gravity-gradient stabilization, tidal stabilisation and orbital plasma dynamics. The missions have met with varying degrees of success; a few have been highly successful. Description Tethered satellites are composed of three parts: the base-satellite; tether; and sub-satellite. The base-satellite contains the sub-satellite and tether until deployment. Sometimes the base-satellite is another basic satellite, other times it could be a spacecraft, space station, or the Moon. The tether is what keeps the two satellites connected. The sub-satellite is released from the base assisted by a spring ejection system, centrifugal force or gravity gradient effects. Tethers can be deployed for a range of applications, including electrodynamic propulsion, momentum exchange, artificial gravity, deployment of sensors or antennas etc. Tethe ...

STS-75
STS-75 was a 1996 NASA Space Shuttle mission, the 19th mission of the ''Columbia'' orbiter. Crew Allen, Hoffman, Nicollier and Chang-Díaz had previously been members of the STS-46 crew, which had flown the TSS-1 experiment in 1992. Mission objective Tethered Satellite System The primary objective of STS-75 was to carry the Tethered Satellite System Reflight (TSS-1R) into orbit and to deploy it spaceward on a conducting tether. The mission also flew the United States Microgravity Payload (USMP-3) designed to investigate materials science and condensed matter physics. The TSS-1R mission was a reflight of TSS-1 which was flown onboard Space Shuttle ''Atlantis'' on STS-46 in July/August 1992. The Tether Satellite System circled the Earth at an altitude of 296 kilometers, placing the tether system within the rarefied electrically charged layer of the atmosphere known as the ionosphere. STS-75 mission scientists hoped to deploy the tether to a distance of . Over 19 kilometers of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
