We are pleased to announce the Cycle 5 Call for Proposals for James Webb Space Telescope (JWST) General Observer (GO), Survey, and Archival Research (AR) programs. We anticipate allocating up to 8,000 hours in Cycle 5 divided proportionately among Very Small, Small, Medium, and Large/Treasury programs, depending on proposals pressure. We invite scientists to participate in this opportunity, which is open to all categories of organizations, both domestic and foreign, including educational institutions, profit and nonprofit organizations, NASA Centers, and other Government agencies.

Proposals are due on October 15, 2025 by 8:00 p.m. U.S. Eastern Daylight Time. The Cycle 5 Telescope Allocation Committee will meet in the first two weeks of February 2026, with selections announced in March 2026. Cycle 5 observations are planned to begin July 1, 2026.
