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 proposal deadline is Friday, April 6, 2018, 8pm Eastern Time.
The Time Allocation Committee will meet in late June 2018, with results announced in July 2018.
The Budget deadline is Thursday, August 30, 2018, 8pm Eastern Time.
Cycle 1 observations will start after a 6 month commissioning period. The start date will depend on when JWST launches within the March 31 - June 29 2019 launch window. Cycle 1 will have a duration of one year. Time-constrained observations can be submitted for the period October 1 2019 to December 31 2020.
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), 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.
