The XRISM Key Program
Announcement of the first XRISM Key Program (KP)
The first Key Program (KP) Call for Proposal is now open. See this document.
Proposal deadline is 23:59 UT on Thursday, December 3, 2026.
The Cycle 3 Proposers' Observatory Guide (POG) is sufficient for advanced planning of KP proposals. We plan to publish updates in mid-October, 2026. ARK/RPS for KP will be available only at ISAS/JAXA, and will open for submission in mid-October, 2026. ARK/RPS at NASA and ESA will not be opened for the submission of KP proposals.
