Spacelab was the scientific laboratory used aboard the Space Shuttle. Ten European nations contributed to the development of Spacelab through the European Space Agency and in partnership with NASA. Spacelab was first flown on STS-9 aboard Space Shuttle Columbia in 1983, and was last flown on STS-90 in 1998. Spacelab flights carried either the module, a pallet, or the Spacelab Multipurpose Experiment Support Structure (MPESS) in the payload bay of the Shuttle. Experiments on Spacelab focused on the life sciences, micro-gravity, and observations of Earth and its atmosphere.
