Amendment 59: Several Updates to the ROSES-25 Summary of Solicitation
Research Opportunities in Space and Earth Sciences (ROSES)-2025 is an ongoing "omnibus" or "umbrella" solicitation meaning that it includes many individual program elements each with its own topics and due dates. Refer to Table 3 of ROSES-25 for a list of those program elements. The ROSES-25 "Summary of Solicitation" is the front matter that sets the default backstop rules for each of the program elements in ROSES-25.
ROSES-25 Amendment 59 makes several additions, changes, and clarifications to the ROSES-25 Summary of Solicitation to conform with Agency and administration priorities, see Sections I, I(g), II(a), II(b), III(b), III(d), V(b)ii, VI(c) & VIII(b). New text is in bold.
