The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) is announcing the release of its annual NASA Research Announcement (NRA), Research Opportunities in Space and Earth Sciences (ROSES) - 2024. ROSES is an omnibus solicitation with multiple program elements, each with its own due dates and topics. This solicitation covers a wide range of basic and applied supporting research and technology in space and Earth sciences supported by SMD. The ROSES NRA allows for grants, cooperative agreements, contracts, and inter- or intra-agency transfers, depending on the nature of the work proposed. Non-governmental organizations are eligible to submit proposals without restriction on teaming arrangements. The awards range from under $100K per year to more than $1M per year, with periods of performance typically lasting three years. Electronic submission of proposals is required, and organizations must be registered with NSPIRES or Grants.gov. Notices of intent to propose and Step-1 Proposals will be due starting March 27, 2024, and Full (Step-2) Proposals will be due no earlier than May 14, 2024. Potential proposers are encouraged to read the ROSES Summary of Solicitation and FAQ#1 for significant changes from recent ROSES.
