Mission overview

STS -55 is better known as the second German Spacelab Mission D-2, which was conducted eight years after the first flight (D1 with STS -61 -A) in German speaking countries. Despite the designation of the flight was international: the 88 scientific experiments were created next to the DLR from NASA, ESA, and the French and the Japanese space agency. The crew worked two shifts around the clock.

The launch was scheduled for February 1993, but was postponed several times. On March 22, the start had to be aborted when the main engines had been switched on for three seconds before liftoff. The computer indicated that one of the three engines did not develop a full thrust. All three engines were replaced. The launch attempt on April 26 was finally successful.

In the course of the mission, numerous attempts have been carried out in the Spacelab. Dating from Europe module was equipped with the Anthrorack (Human Medical experiments on astronauts ), the bio lab ( Biological tests), the materials laboratory and other test facilities. Many experiments built on those of the D1 mission, however, had been, for example, improved by more accurate methods.

By the astronaut and physician Dr. Bernard Harris, intravenous access was first in space an astronaut (Hans Schlegel ) placed through which a saline solution was injected. This was part of a study designed to investigate the replacement of a result of adaptation to weightlessness lost fluid. Other crew members also took part.

Tests with Rotex, a remote controlled from Earth lightweight robot arm, were very successful. For the first time it was possible to remotely capture a free -floating object.

The landing had to be diverted due to bad weather at the Kennedy Space Center at Cape Canaveral to Edwards Air Force Base in California.
