NASA Headquarters is offering the ROSES 2025: C.10 Cassini Data Analysis Program, a federal grant opportunity aimed at supporting research and development in space and Earth sciences. Eligible applicants must be affiliated with a U.S. institution, as NASA primarily funds domestic organizations, although some provisions exist for international collaboration under specific guidelines. This program is part of NASA's broader Research Opportunities in Space and Earth Sciences (ROSES) initiative, which encompasses various research topics and aims to advance scientific knowledge in planetary science. Proposals must be submitted in two steps, with the Step-1 proposal due by June 6, 2025, and the Step-2 submission deadline set for August 14, 2025. For further details, interested parties can contact Nicholas Lang or Henry Throop at HQ-CDAP@mail.nasa.gov, and additional information can be found at https://solicitation.nasaprs.com/ROSES2025.
