Mission Highlights:

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.
