Mission overview

Originally, the space shuttle Atlantis was to leave on 23 March 1992. One occurred during refueling excessive fuel concentration ( liquid hydrogen and oxygen ) in Orbiterheck enforced a 24 -hour shift. The engineers went assume that the problem with the thermal loads on the fuel lines was related, because the troubleshooting had not given any leakage. The preparations for the start of the next day ran smoothly.

The mission carried the first Atmospheric Laboratory for Applications and Science ( ATLAS -1) on two Spacelab pallets in the cargo bay of the shuttle. The installed in the payload bay cargo consisted of twelve instruments from the U.S., France, Germany, Belgium, Switzerland, the Netherlands and Japan. There have been studies in the areas of atmospheric chemistry, solar radiation, plasma physics and ultraviolet astronomy. Other research projects have included the Shuttle Solar Backscatter Ultraviolet Experiment ( SSBUV ) and the Get Away Special Experiment ( GAS ).

The landing took place on April 2 at 11:23 UTC on the runway 33 at the Kennedy Space Center. The mission lasted a day longer than planned in order to continue scientific experiments can.
