The Nancy Grace Roman Space Telescope Cycle 1 Call for Proposals is expected to open in Fall 2025, with the proposal deadline being approximately four months after the Call is issued. The Call will solicit proposals to fund the analysis of Roman data across a broad range of science areas, as well as theoretical investigations or ground-based data analysis with direct relevance to Roman science. Proposals requesting observing time for General Astrophysics Surveys with the Wide Field Instrument in imaging or spectroscopic mode will also be solicited. The Science Support Center at IPAC, together with the Science Operations Center at STScI, will host a number of proposal preparation workshops to introduce the community to Roman proposal tools and other specific elements of the Cycle 1 Call.
