NASA’s Science Mission Directorate (SMD) announces the release of its annual omnibus solicitation for basic and applied research, Research Opportunities in Space and Earth Science (ROSES) 2021 as NNH21ZDA001N on or about February 12, 2021, on the NSPIRES web page at


ROSES is an omnibus solicitation, with many individual program elements, each with its own due dates and topics. Table 2 and Table 3 of this NRA, which will be posted at and, respectively, provide proposal due dates and hypertext links to descriptions of the solicited program elements in the Appendices of this NRA. Together, these program elements cover the wide range of basic and applied supporting research and technology in space and Earth sciences supported by SMD.


The ROSES NRA is written to allow program elements to issue 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 awards deriving from ROSES will be grants, and almost all program elements of ROSES specifically exclude contracts because it would not be appropriate for the nature of the work solicited. 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.


Awards range from under $100K per year for focused, limited efforts (e.g., data analysis) to more than $1M per year for extensive activities (e.g., development of hardware for science experiments and/or flight). Periods of performance are typically three years, but some programs may allow up to five years and others specify shorter periods.


The funds available and the anticipated number of awards are given in each program element and range from less than one to several million dollars, which allows for selection from a few to as many as several dozen proposals. 


Electronic submission of proposals is required by the respective due dates for each program element and must be submitted by an authorized official of the proposing organization. Electronic proposals may be submitted via the NASA proposal data system NSPIRES or via


Every organization that intends to submit a proposal in response to ROSES-2021 must be registered with NSPIRES; organizations that intend to submit proposals via must be registered with, in addition to being registered with NSPIRES. Such registration must identify the authorized organizational representative(s) (AOR) who will submit the electronic proposal. All proposal team members must be registered in NSPIRES regardless of the submission system, so we may perform automatic organizational conflict of interest checking of reviewers. Potential proposers and proposing organizations are urged to access the system(s) well in advance of the proposal due date(s) of interest to familiarize themselves with its structure and to enter the requested information.


Notices of intent to propose and Step-1 Proposals will be due starting in April 2021 and Full (Step-2) Proposals will be due no earlier than May 13, 2021 through no later than May 14, 2022, by which time it is expected that the next ROSES solicitation will be released.


Potential proposers are strongly encouraged to read Section I(d) of the ROSES Summary of Solicitation that lists Significant Changes from Recent ROSES.
