Mission description

The Columbia mission was Spacelab's 22nd and final deployment . During the NeuroLab mission, the main focus was on the functioning of the brain . For this purpose, studies were carried out on humans and animals . In addition to the 7 space travelers, there were also 18 pregnant mice , 152  rats , 135  snails , 229 swordtail fish , 4 oyster fish and 1514 crickets on board . Most of the animals, however, were either killed and examined in orbit or after landing. A large number also died in flight. Investigations concerned embryonic development , brain tissue and activity as well as the sense of balance . For this purpose, the oyster fish had special electrodes implanted in the inner ear .

Extensive investigations were also carried out on four astronauts. Sleep was carefully examined in all its phases (brain and body functions). The coordination of brain and body movements was also researched. To do this, the test subjects had to catch balls and follow points of light with their eyes. Other tests covered adaptation to weightlessness, the function of the sense of balance, the use of medication for space traveler's disease , the treatment of insomnia, dizziness, low blood pressure and symptoms of immunodeficiency .
