Tether Experiments

A number of tether experiments have been flown in space. In the early days of the space age the Gemini 11 and 12 missions (1966) used short tethers to connect two spacecraft and rotate them around each other to study artificial gravity and other dynamics.

In the 1990s the National Aeronautics and Space Administration (NASA) conducted two series of tether experiments. One series involved a large tether flown on the space shuttle that was called the Tethered Satellite System (TSS). Unfortunately, the TSS missions encountered well-publicized problems. In the 1992 TSS-1 mission, the TSS system attempted to deploy a spherical satellite built by the Italian space agency upwards from the shuttle at the end of a 20-kilometer-long (12 miles) tether made of insulated copper wire. A few hundred meters into deployment the spool mechanism jammed, ending the experiment.

In 1996 NASA repeated the experiment. As the tether approached its full length, the rapid...
