Spacelab wasSpacelab was a reusable laboratory used on certain spaceflights flown by the Space Shuttle. The laboratory comprised multiple components, including a pressurized module, an unpressurized carrier and other related hardware housed in the Shuttle's cargo bay. The components were arranged in various configurations to meet the needs of each spaceflight.
Spacelab components flew on 22 Shuttle missions between November 1983 and April 1998. Spacelab allowed scientists to perform experiments in microgravity in Earth orbit.
This flight carried first Spacelab mission and first astronaut to represent the European Space Agency (ESA), Ulf Merbold of Germany. ESA and NASA jointly sponsored the Spacelab-1 and conducted investigations which demonstrated the capability for advanced research in space. Spacelab is an orbital laboratory and contains an observations platform composed of cylindrical pressurized modules and U-shaped unpressurized pallets which remain in the orbiter's cargo bay during flight. Altogether 73 separate investigations were carried out in astronomy and physics, atmospheric physics, Earth observations, life sciences, materials sciences, space plasma physics and technology. This was the first time six persons were carried into space on a single vehicle.
