XRISM Key Program Call for Proposals
Observations for the first Key Programs are scheduled to begin in June 2027. The proposal submission deadline is 4 December 2026. The post XRISM Key Program Call for Proposals appeared first on NASA Science .
The X-ray Imaging and Spectroscopy Mission (XRISM) marked its 3-year anniversary this weekend, having already produced groundbreaking discoveries in various cosmic topics. These include the formation of large-scale structures, co-evolution of galaxies and supermassive black holes, and plasma physics, as well as numerous unexpected findings.
In response to these successes, the XRISM project has introduced Key Programs, offering researchers worldwide the chance to submit proposals for strategic, large-scale observation projects.
The objective of these Key Programs is to generate legacy data and scientific results of significant value to the astronomical community. The first set of observations under these programs is expected to commence in June 2027, with an allocation of roughly 3 million seconds of observing time. Researchers have until 4 December 2026, at 8:59a Japan Standard Time (or 3 December 2026 at 6:59p Eastern, 3:59p Pacific) to submit their proposals.
Important to note is that data collected through Key Program observations will be publicly accessible without any exclusive access period. For those interested in learning more about the program, application guidelines, and updated science objectives, the Call for Proposals is available on the Key Program webpage.
