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


March 27 2018: Based on recommendations made by the JWST Standing Review Board, NASA is re-scheduling JWST’s launch window for 2020. Given those circumstances, STScI will delay the Cycle 1 GO/AR proposal deadline until no earlier than February 1 2019.

A revised proposal schedule will be developed in consultation with the JWST Users Committee, the JWST Project and representatives from the European and Canadian Space Agencies. Proposals already submitted in response to the Cycle 1 Call will not be carried over and will need to be resubmitted. 


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 are listed here JWST Cycle 1 GTO Observations Available for Archival Proposals .

February 20 2018: The GTO and ERS teams have finalized their observations for Cycle 1. The targets and high-level instrument modes are listed in this spreadsheet GTO & ERS observations (please download for readability); for further details, please use the Program Information Tool to consult the APT files.

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.

Important Dates

The Cycle 1 proposal deadline is TBD, no earlier than February 1, 2019.

The Time Allocation Committee meeting date will be announced at a later date.

The Budget deadline is TBD.

Cycle 1 observations will start after a 6 month commissioning period. The start date will depend on when JWST launches within the launch window for 2020. Cycle 1 will have a duration of one year. The window for time-constrained observations will be set once the launch window has been more definitively set.

Who's Responsible

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 and Head of the Science Mission Office), Jennifer Lotz, Amaya Moro-Martin, Louis-Gregory Strolger, Brian Williams, and Technical Manager Brett Blacker. The Science Policies Group also includes Claus Leitherer, Alessandra Aloisi, Andy Fruchter, and Molly Peeples. As delegated by NASA Headquarters, the selection official for JWST proposals is the STScI Director.
