Mission overview

The start of the mission took place without any delay, the second time was started at night.

Within the mission three communications satellites were brought into orbit: Morelos -B ( Mexico), AUSSAT -2 ( Australia) and SATCOM KU -2. Another main goal, attempts to assemble structural elements in free space, in view of the construction of the International Space Station. These two spacewalks of twelve hours and ten minutes duration were necessary. In this mission, the IMAX camera was carried.

The landing was a mission in orbit earlier than planned in Edwards AFB in California. The shortening of the mission was decided at short notice due to the storm situation in the country area; also put the space shuttle on the concrete runway, because the nature runway normally used in the dry lake was too wet. Atlantis was transported back four days later by a special aircraft to Cape Canaveral, Florida.
