JWST Opportunities and Policies

Articles in this section comprise the traditional call for proposals. These articles include information on observing and science policies, and details on the proposal submission process (including checklists). Other sections, that are selectable from the left sidebar menu, provide information on the observatory and instrumentation, observation planning, and data calibration and analysis. Downloadable PDF collections are provided as a courtesy, made available and updated when feasible. The online documentation is the authority, and will be updated with the latest information.

Release Notice: January 23 2020 (updated July 23, 2020)

We are pleased to announce the Cycle 1 Call for Proposals for James Webb Space Telescope (JWST) observations and funding for archival research programs.

Participation in this program is open to all categories of organizations, both domestic and foreign, including educational institutions, profit and nonprofit organizations, NASA Centers, and other Government agencies.

JWST is now on track to a launch readiness date of October 31, 2021. Science observations for Cycle 1 will commence after a 6 month commissioning phase. We will accept proposals for all instruments: MIRI, NIRCam, NIRSpec, and NIRISS.

We anticipate up to 6000 hours offered for GO programs this cycle. See the JWST Call for Proposals for Cycle 1 for further details.

This solicitation for proposals will be open through November 24, 2020 by 8pm ET. The Astronomer's Proposal Tool (APT) is required for proposal submission. Results of the selection will be announced in late August 2020.

Questions can be addressed to the STScI JWST Help Desk (http://jwsthelp.stsci.edu) where you can submit questions directly to the appropriate team of experts.

The Cycle 1 Call for Proposals

The Call for Proposals (CfP) invites the astronomical community to propose for observing time on JWST in a given cycle (nominally one year in duration). It summarizes the policies and procedures for proposing in that cycle of JWST observing, including requests for research funding on archival JWST data. See the JWST Call for Proposals for Cycle 1 for more information.

The James Webb Space Telescope offers proposal opportunities for General Observers (GO) and Archival Proposals (AR), Guaranteed-Time Observers (GTO), and Early Release Science Programs (DD ERS) during Cycle 1. JWST is now on track to a launch readiness date of October 31, 2021. Science observations will commence after a 6 month commissioning phase. 

We invite scientists to participate in the first cycle of investigations with the James Webb Space Telescope (JWST). JWST is an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). JWST is operated and managed by AURA's Space Telescope Science Institute (STScI)

Science justification templates

Templates for JWST Cycle 1 proposal PDF attachments

Note: The templates have intentionally different margins to accommodate about the same amount of text per page.

Proposers are encouraged to refer to Getting Started with JWST Proposing in planning and submitting their proposals. Proposers should also be familiar with the policies on data rights, duplications, and other important topics covered in JWST General Science Policies.

JWST general science policies

James Webb Space Telescope (JWST) science programs are required to follow STScI and NASA policy regarding requested time allocations, duplicate observations, data rights, and funding.
