NASA Headquarters is offering a federal grant opportunity titled "ROSES 2025: A.7 Water Quality Applications," aimed at advancing research in water quality applications within the context of space and Earth sciences. Proposers must be affiliated with a U.S. institution, as NASA primarily funds domestic organizations, although some provisions exist for non-U.S. entities under specific guidelines. This grant is part of NASA's broader Research Opportunities in Space and Earth Sciences (ROSES) initiative, which supports a wide range of scientific research and technology development. Interested applicants must submit a mandatory Notice of Intent by August 19, 2025, with the full proposal due by October 21, 2025.
