  • We have changed the requirements for Survey programs. Individual visits are generally expected to have a total duration of less than 90-100 minutes, including the science integration time and all associated overheads. Longer visits are possible but may be more difficult to schedule. See Survey Programs for more information.

Welcome

We invite scientists to participate in Cycle 2 of the James Webb Space Telescope (JWST). The telescope and its instruments were built under the auspices of the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and the Canadian Space Agency (CSA). Management of JWST's scientific program is carried out by the Space Telescope Science Institute (STScI). We anticipate allocating up to 5,000 hours in this cycle, including 2,900 hours for Small programs (≤ 25 hours), 1,250 for Medium programs (> 25 and ≤ 75 hours), and 850 for Large programs (> 75 hours). Abstracts of previously accepted programs can be found on the JWST proposal catalogs webpage.

This document establishes the goals, requirements, and policies for General Observer (GO) and Archival Research (AR) programs in Cycle 2. The table of contents for the web version of this document is on the left side of the page, and links there can take you to any page from any other page (click the arrow to expand the entire table of contents under "JWST Call for Proposals for Cycle 2").
