Space Telescope Science (STSscI) Institute Established in 1981, the STSscI helped guide the most famous observatory in history, the Hubble Space Telescope. Since its launch in 1990, STSscI has performed the science operations for Hubble. Currently, STSscI is leading the science and mission operations for the James Webb Space Telescope (JWST), planned to launch in 2021. STSscI staff conducts world-class scientific research, and its Barbara A. Mikulski Archive for Space Telescopes (MAST) curates and disseminates data from over 20 astronomical missions.
