The Spartan (Shuttle Point Autonomous Research Tool for Astronomy) satellite was a reusable free-flying astronomical observatory which was deployed and then retrieved by the US Space Shuttle's Remote Manipulator System arm. The most often flow Spartan-201's main payload was the UVCS and WLC telescope package containing the SAO/Cambridge ultraviolet spectrometer and the HAO/Boulder white light coronagraph. Secondary equipment varied by mission - for example, the fifth flight had a target for the VGS laser, and sample plates to trap beryllium ions from the solar wind.
