NASA Headquarters is offering a federal grant opportunity titled "ROSES 2025: A.8 Water Resources Applications," aimed at supporting research and development in water resources applications. 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 various program elements focused on advancing scientific knowledge and technology. Interested applicants should note that the Step-1 proposal is due by September 5, 2025, with the Step-2 proposal deadline set for November 14, 2025.
