The GALEX mission was developed under NASA's Explorers Program, which is managed by the NASA's Goddard Space Flight Center in Greenbelt, Maryland.

The GALEX mission is a partnership between the California Institute of Technology (Caltech) and NASA's Jet Propulsion Laboratory (JPL) with universities, science institutes, laboratories, and commercial technology providers from around the world. Caltech in Pasadena, California, hosts the GALEX science center and has overall responsibility for the project. JPL in Pasadena, California, constructed the GALEX science instrument, performed calibration, and is responsible for project management. Leading the GALEX project is the principal investigator, professor Chris Martin, of Caltech.
