Mission overview
The 49th space shuttle mission began with a problem-free start on July 31, 1992. With this start two nations were able to celebrate their first citizens in space, namely the Swiss Claude Nicollier and the Italian Franco Malerba .
The two main objectives of the mission were the launching of the free-flying experiment platform EURECA (European Retrievable Carrier) and the TSS experiment (Tethered Satellite Systems). EURECA was a reusable platform that contained over 70 experiments. She was suspended from the mission by the astronauts a day later than planned due to problems with her computer. As a result, the STS-46 flight was extended by one day. After igniting the satellite's engines, the burning phase was aborted a little too early, so a corrective ignition had to be carried out on the sixth day of flight of the mission in order to reach the planned altitude. A year later, the satellite was recaptured as part of the STS-57 mission .
After the successful launch of EURECA, the space tether experiment TSS was started. TSS was a tethered satellite weighing around 500 kilograms, which was supposed to float in space on a 20 kilometers long steel cable away from the shuttle. The aim of this experiment was to generate electrical energy. The cable to the satellite got stuck after about 260 meters, so practically no results could be obtained. The crew tried for several days to get the satellite free, but it failed. Therefore it was stowed back in the payload bay to return to earth.
The mission ended on August 8, 1992 with a landing at KSC in Florida.
