- Primary payload was Spacelab-3. First operational flight for
Spacelab orbital laboratory series developed by European Space
Agency. Five basic discipline areas: materials sciences, life sciences,
fluid mechanics, atmospheric physics. and astronomy main mission
objective with Spacelab-3 was to provide high quality microgravity
environment for delicate materials processing and fluid experiments.
Two monkeys and 24 rodents observed for effects of weightlessness.
Of 15 Spacelab
primary experiments conducted, 14 considered successful.
Two Get Away Specials on board.
