NASA Headquarters is offering a federal grant opportunity titled "ROSES 2024: A.65 Responsive Science Initiatives Research," aimed at advancing research in space and Earth sciences. Eligible applicants must be affiliated with a U.S. institution, and while organizations outside the U.S. can apply under specific conditions, NASA primarily funds domestic proposals. This initiative is part of the broader Research Opportunities in Space and Earth Sciences (ROSES) program, which encompasses various research and technology projects, with most awards expected to be grants. Interested parties should note that optional Notices of Intent are due by January 24, 2025, and the application deadline is March 25, 2025.
