Originally, Michael Lampton was scheduled for this flight but was replaced by Frimout for medical reasons. Also, was Charles Chappell backup payload specialist.

Mission overview

Originally the space shuttle Atlantis was supposed to leave on March 23, 1992. An excessive concentration of fuel (liquid hydrogen and oxygen) in the orbiter stern during refueling forced a 24-hour shift. The engineers assumed that the problem was related to the thermal loads on the fuel lines, because troubleshooting had not revealed a leak. The preparations for the start the next day went 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 load installed in the payload bay consisted of twelve instruments from the USA, France, Germany, Belgium, Switzerland, the Netherlands and Japan. Studies have been conducted in the fields of atmospheric chemistry , solar radiation , plasma physics, and ultraviolet astronomy . The two Atlas pallets alone contained 14 experimental arrangements for examining the ozone layer, the load on the earth's atmosphere and the temperature and pressure distribution. These included several spectrometers , a millimeter wave measuring device , radiometer , photometer and particle accelerator. A Japanese electron gun was also supposed to create artificial aurora borealis, which was only partially successful. The FAUST UV telescope even failed completely after half of the observations. The commander and pilot carried out more than 200 changes in position in order to align the instruments with the planned observation targets. Other research projects 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 runway 33 in the Kennedy Space Center . The mission lasted a day longer than planned in order to continue scientific experiments.
