Cycle 1 Frequently Asked Questions

Q: Given the delay in the launch of JWST until 2021, will the Cycle 1 Call for Proposals be delayed?

A: The Cycle 1 GO Call for Proposals was issued on November 30, 2017, following the original schedule. However, the deadline for proposal submission has been extended from April 6, 2018 until no earlier than February 1, 2019. The 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.  

Q: Will there be an opportunity to propose observations based on new scientific discoveries and information that arise after the nominal Cycle 1 Call for Proposals deadline?

A: Yes. STScI and the GSFC JWST Project science team are working with the JWST Users Committee (JSTUC) on developing a Supplemental Call for Proposals. A prime aim will be to provide an avenue for JWST follow-up observations of discoveries made subsequent to the Cycle 1 GO deadline.

Q: When will the Cycle 1 Supplemental Call for Proposals be issued and reviewed?

A: The implementation schedule is being developed with the JSTUC, but it is likely that the selection process will be completed 2-3 months after JWST’s launch. 

Q: How will the Cycle 1 Supplemental Proposals be reviewed, and what will be the criteria against which they are judged and selected?

A: The Cycle 1 supplemental proposals will be peer reviewed. The detailed implementation plan and proposal criteria are under development in consultation with the JSTUC. Proposers will need to justify why the observations could not have been submitted in response to the standard Cycle 1 GO Call. Cycle 1 supplemental proposals will be subject to the standard duplication policies and grant support. 

Q: When will approved Cycle 1 Supplemental Proposals be implemented?

A: Approved Cycle 1 Supplemental programs will be incorporated in the Cycle 1 Long Range Planning schedule and will be executed along with Cycle 1 GO programs. The prime criterion in scheduling observations will be to maximize the JWST observing efficiency. 

Q: Will the launch delay for JWST affect the timing of the next (Cycle 26) Call for Proposals for the Hubble Space Telescope?

A: No. The Cycle 26 Call will be issued on May 1, 2018; the proposal deadline is August 17, 2018; and the TAC will meet during the week of October 8, 2018.

Q: Where can I find more information on these matters?

A: The JWST Cycle 1 GO Call for Proposals was published on November 30, 2017. It is available on JDox. Further community updates will be communicated through JWST Observer news.
