Subject: ROSES-2023 Updates Regarding Open Science and Data Management Plan to Summary of Solicitation and Research Overviews.

On or about May 15, 2023, Section II(c) of the ROSES-2023 Summary of Solicitation and the six research overviews (A.1, B.1…) have been updated in two ways regarding the "Open Science and Data Management Plan" (OSDMP):

1) to include a link to the new SMD Open-Source Science Guidance document at https://science.nasa.gov/oss-guidance to help proposers write their plans and

2) An important clarification regarding software archiving: The method of archiving software will not result in a weakness for proposals to ROSES-2023.

Where appropriate, in both the ROSES-2023 Summary of Solicitation and the six research overviews other small updates were also made, such as to the list of program elements and the references to the "Proposer's Guide" (formerly the Guidebook for Proposers). New text is in bold.

General questions concerning the ROSES-2023 Summary of Solicitation may be directed to Max Bernstein at SARA@nasa.gov, General questions concerning the OSDMP may be directed to HQ-SMD-SPD41@mail.nasa.gov, questions regarding the division overviews may be directed to the R&A leads, and questions about particular program elements directed to their respective point(s) of contact, all of whom may be found on the Program Officers list.
