placeholder JWST Call for Proposals for Cycle 1
The policies governing the JWST General Observer (GO) and Archival Research (AR) programs in Cycle 1 are established in this Call for Proposals.
Late breaking news
April 25, 2019: JWST Cycle 1 GTO Call re-opened and updated Cycle 1 science timeline released. The Cycle 1 GO Call will be released on January 23, 2020.
July 12 2018: Following the completion of the assessment by the Independent Review Board, NASA has announced a launch date of March 30 2021 for JWST.
March 27 2018: Based on recommendations made by the JWST Standing Review Board, NASA is re-scheduling JWST’s launch window.
March 13 2018: Successful JWST proposers will be eligible to apply for NASA High-End Computing Time. Please indicate whether you intend to apply for HEC time in the text of the Special Requirements section of the PDF submission. More information on NASA HEC Program can be found on https://www.hec.nasa.gov.
February 22 2018: A number of GTO programs will be making some or all of their data immediately available with no exclusive access period. Those data will be available for Cycle 1 archival research programs. The relevant programs and datasets will be listed on JWST Cycle 1 GTO Observations Available for Archival Proposals.
About this document
We invite scientists to participate in Cycle 1 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). JWST observing programs are allocated against wall-clock time, with up to 6,000 hours available for general observers in this cycle, divided by program sizes as 3,500 hours for Small programs (≤ 25 hours), 1,500 for Medium programs (> 25 and ≤ 75 hours), and 1,000 for Large programs (> 75 hours). Observing time has already been allocated for Guaranteed Time Observations (GTO) and Director's Discretionary Early Release Science (DD-ERS) programs. This document establishes the goals, requirements, and policies for the General Observer (GO) and Archival Research (AR) programs in Cycle 1.

The Cycle 1 GO Call is currently being updated and will be formally released on January 23 2020.
The online documentation is the authority, and will be updated with the latest information.
The Cycle 1 proposal deadline is May 1 2020
The Time Allocation Committee meeting date will be scheduled for late July/early August 2020.
The Budget deadline is TBD.
Cycle 1 observations will start after a 6 month commissioning period. NASA has announced March 30, 2021 as the formal launch date. Cycle 1 will have a duration of one year. The window for time-constrained observations will be set when the Cycle 1 GO Call is released.
Members of the Science Mission Office at STScI are responsible for the oversight of the JWST science program selection process. The members involved include Neill Reid (Associate Director for Science), Alessandra Aloisi (Head of the Science Mission Office), Amaya Moro-Martin, Louis-Gregory Strolger, and Technical Manager Brett Blacker. The Science Policies Group also includes Claus Leitherer, Katey Alatalo, Christine Chen, Andy Fruchter, and Molly Peeples. As delegated by NASA Headquarters, the selection official for JWST proposals is the STScI Director.
