The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) announces that its annual NASA Research Announcement (NRA), Research Opportunities in Space and Earth Sciences (ROSES) – 2023 (OMB Approval Number 2700-0092) has been released on February 14, 2023. ROSES is an omnibus NRA, with many individual program elements, each with its own due dates and topics. All together these cover the wide range of basic and applied supporting research and technology in space and Earth sciences supported by SMD. Awards will be made as grants, cooperative agreements, contracts, and inter- or intra-agency transfers, depending on the nature of the work proposed, the proposing organization, and/or program requirements. However, most extramural research awards deriving from ROSES will be grants, and many program elements of ROSES specifically exclude contracts, because contracts would not be appropriate for the nature of the work solicited. The typical period of performance for an award is three years, but some programs may allow up to five years and others specify shorter periods. Organizations of every type, domestic and foreign, Government and private, for profit and not-for-profit, may submit proposals without restriction on teaming arrangements. Note that it is NASA policy that all research involving non-U.S. organizations will be conducted on the basis of no exchange of funds. This ROSES-2023 NRA will be available on its release or about February 14, 2023, at http://solicitation.nasaprs.com/ROSES2023. Tables 2 and 3 of this NRA, which will be posted at http://solicitation.nasaprs.com/ROSES2023table2 and http://solicitation.nasaprs.com/ROSES2023table3, respectively, provide proposal due dates and hypertext links to descriptions of the solicited program elements in the Appendices of this NRA. Frequently asked questions about ROSES-2023 will be posted at http://science.nasa.gov/researchers/sara/faqs/. Further information about specific program elements may be obtained, after the release of ROSES-2023, from the individual Program Officers listed in the Summary of Key Information at the end of each program element of ROSES-2023 and at: http://science.nasa.gov/researchers/sara/program-officers-list/. Questions concerning general ROSES-2023 policies and procedures may be directed to Max Bernstein, Lead for Research, Science Mission Directorate, at firstname.lastname@example.org.
