A manned space laboratory for conducting various experiments in space. It was developed by the European Space Agency in response to NASA's invitation to participate in the Space Shuttle program. It consists of a pressurized module (laboratory) that is sealed and has a diameter of 4.2 meters and is kept at a constant pressure inside, and a pallet (platform) that is exposed to space. Spacelab will be loaded into the cargo bay of the Space Shuttle and transported into orbit, where it will conduct material experiments, life science experiments, and other experiments in space.
