NASA Headquarters is offering a federal grant opportunity titled "ROSES 2024: A.22 NASA Energy and Water Cycle Study," aimed at advancing research in Earth sciences. 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 the broader Research Opportunities in Space and Earth Sciences (ROSES) initiative, which encompasses various research and technology programs, with awards typically structured as grants, cooperative agreements, or contracts, and a standard performance period of three years. Interested applicants should submit optional Notices of Intent by January 9, 2025, and can access further details and application instructions through the NSPIRES platform, with the proposal submission deadline set for February 20, 2025.
