The JWST Cycle 1 GO Proposal Schedule: What To Expect
On March 27, 2018, NASA announced a postponement of the launch of the James Webb Space Telescope. With the completion of the report by the Independent Review Board, NASA has developed a revised schedule, setting a launch date of March 30, 2021. Working in conjunction with the JWST Project at Goddard Space Flight Center (GSFC) and the JWST Users Committee (JSTUC), STScI has developed an outline for the Cycle 1 proposal process.
STScI anticipates re-issuing the Cycle 1 Call for Proposals around New Year 2019/2020, and the proposal deadline will fall in the March-May 2020 timeframe. The Time Allocation Committee will meet in the summer of 2020. Following NASA policy, any changes to the GTO and Early Release Science programs must be finalized 7 months in advance of the Cycle 1 Call for Proposals – or in late spring 2019.
The final schedule for the Cycle 1 proposal process will be announced in early 2019. A total of ~6,000 hours will be offered for GO programs. The available time includes ~20% over-subscription, which is essential to ensure efficient use of the observing time throughout the cycle. Any programs not completed during Cycle 1 will roll over into Cycle 2. As in the original Call, programs will be grouped by size as Small, Medium, and Large programs, but the overall balance in time allocation in Cycle 1 will be weighted towards smaller programs.
