This synopsis is a generic summary that is posted for each of the many individual "program elements" in NASA’s Research Opportunities in Space and Earth Sciences (ROSES) – 2025 solicitation. For specific information on this particular program element download and read the PDF of the text of this program element by going to Tables 2 or 3 of ROSES at https://solicitation.nasaprs.com/ROSES2025table2 and https://solicitation.nasaprs.com/ROSES2025table3, respectively, click the title of the program element of interest, a hypertext link will take you to a page for that particular program element. On that page, on the right side under "Announcement Documents" the link on the bottom will be to the PDF of the text of the call for proposals. For example, if one were interested in the Solar System Science program (NNH25ZDA001N-SCUBED) one would follow the link to the NSPIRES page for that program element and then to read the text of the call one would click on “C.2 Solar System Science (.pdf)” to download the text of the call. If one wanted to set it into the context of the goals, o
