Space Shuttle Project

A crewmember aboard the Space Shuttle Orbiter Atlantis (STS-46) used a 70mm handheld camera to capture this medium closeup view of early operations with the Tethered Satellite System (TSS). TSS-1 is being deployed from its boom as it is perched above the cargo bay of the Earth-orbiting Shuttle circling the Earth at an altitude of 296 kilometers (184 miles), the TSS-1 will be well within the tenuous, electrically charged layer of the atmosphere known as the ionosphere. There, a satellite attached to the orbiter by a thin conducting cord, or tether, will be reeled from the Shuttle payload bay. On this mission the satellite was plarned to be deployed 20 kilometers (12.5 miles) above the Shuttle. The conducting tether will generate high voltage and electrical currents as it moves through the atmosphere allowing scientists to examine the electrodynamics of a conducting tether system. These studies will not only increase our understanding of physical processes in the near-Earth space environment, but will also help provide an explanation for events witnessed elsewhere in the solar system. The crew of the STS-46 mission were unable to reel the satellite as planned. After several unsuccess
