On June 27, NASA announced a revised schedule for the James Webb Space Telescope, with a new launch date on March 30, 2021. The Space Telescope Science Institute (STScI) anticipates releasing the Call for Proposals for Cycle 1 General Observations (GO) approximately 12 months before launch (L-12 months), with a proposal deadline 3 months later (L-9 months). A final schedule for Cycle 1 proposals will be developed in consultation with the JWST Users Committee, the JWST Project, and representatives from the European and Canadian Space Agencies.

JWST is NASA’s next flagship observatory, enabling a wide range of ground-breaking science spanning the solar system, exoplanets, star- and planet formation, and galaxies near and far. The Early Release Science investigations have already been awarded 460 hours of Cycle 1 Director’s Discretionary time. The Cycle 1 Call for Proposals will offer approximately 6000 hours of General Observer time to the worldwide astronomical community.
