STScI's public outreach activities provide a wide range of resources for media, informal education venues such as planetariums and science museums, and the general public.

The ground system development activities create and maintain the software systems that are needed to provide these services to the astronomy community. The science operations activities directly serve the astronomy community, primarily in the form of HST and JWST (and eventually Roman) observations and grants, but also include distributing data from other NASA and ground-based missions via MAST. STScI operates its missions on behalf of NASA, the worldwide astronomy community, and to the benefit of the public. The total STScI staff consists of about 850 people as of 2021. scientists working at STScI, 15 of whom are ESA staff who are on assignment to the HST project. The staff at STScI consists of scientists (mostly astronomers and astrophysicists), spacecraft engineers, software engineers, data management personnel, education and public outreach experts, and administrative and business support personnel. Most of the funding for STScI activities comes from contracts with NASA's Goddard Space Flight Center but there are smaller activities funded by NASA's Ames Research Center, NASA's Jet Propulsion Laboratory, and the European Space Agency (ESA).

In addition to performing continuing science operations of HST and preparing for scientific exploration with JWST and Roman, STScI manages and operates the Mikulski Archive for Space Telescopes (MAST), which holds data from numerous active and legacy missions, including HST, JWST, Kepler, TESS, Gaia, and Pan-STARRS.

STScI's offices are located on the Johns Hopkins University Homewood Campus and in the Rotunda building in Baltimore, Maryland. STScI was established in 1981 as a community-based science center that is operated for NASA by the Association of Universities for Research in Astronomy (AURA). The Space Telescope Science Institute ( STScI) is the science operations center for the Hubble Space Telescope (HST), science operations and mission operations center for the James Webb Space Telescope (JWST), and science operations center for the Nancy Grace Roman Space Telescope.
