NASA Headquarters is offering a federal grant opportunity titled "ROSES 2025: D.3 Astrophysics Research and Analysis," aimed at supporting research and analysis in astrophysics. Proposers 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 grant is part of NASA's broader Research Opportunities in Space and Earth Sciences (ROSES) initiative, which encompasses a wide range of scientific research and technology development. Interested applicants must submit a mandatory Notice of Intent by December 12, 2025, with proposals due by January 29, 2026. For further details, contact David C. Morris at NASA via email at David.C.Morris@nasa.gov.
