NASA ROSES-25 Amendment 59: Key Updates and Impact on Research Proposals (2026)

In the ever-evolving landscape of space and earth sciences, NASA's ROSES-25 program continues to adapt and evolve, and Amendment 59 is a testament to that. This update is more than just a simple modification; it's a reflection of the agency's commitment to staying aligned with the priorities of the administration and the broader scientific community.

The ROSES Umbrella

At its core, ROSES-25 is an 'omnibus' or 'umbrella' solicitation, a flexible framework that encompasses a multitude of individual program elements, each with its own unique topics and deadlines. This approach allows NASA to respond swiftly to emerging scientific opportunities and priorities. The 'Summary of Solicitation' acts as the guiding document, setting the rules and providing the necessary backstop for each program element.

Amendment 59: A Deep Dive

Amendment 59 introduces several significant changes and clarifications to the ROSES-25 Summary of Solicitation. These updates are designed to ensure that NASA's research efforts remain in sync with the broader goals of the agency and the administration. The amendment touches on various sections, including I, I(g), II(a), II(b), III(b), III(d), V(b)ii, VI(c), and VIII(b). The new text, highlighted in bold, provides clarity and direction to researchers and stakeholders.

One of the most notable aspects of Amendment 59 is its alignment with the proposed revisions to 2 CFR 200, the government-wide guidance for grants and cooperative agreements. These revisions, set to take effect on October 1, 2026, could have a significant impact on the types of costs that are allowable for research projects. Currently, allowable costs include publications, research, and events outside the United States, but these may be subject to restrictions or exceptions under the new guidelines.

Implications and Future Outlook

The potential restrictions on allowable costs could have far-reaching implications for researchers. It may encourage a shift towards more cost-effective research strategies and a focus on domestic research initiatives. However, it's important to note that legal exceptions and special award conditions may provide some flexibility, allowing for a case-by-case approach to funding decisions.

As we await the implementation of these revisions, the scientific community is invited to provide public comments until July 13, 2026. This opportunity for feedback ensures that the final guidelines reflect the needs and concerns of researchers and stakeholders.

A Step Towards Transparency

The transparency and accessibility of NASA's research opportunities are evident in the posting of this amendment. On or around June 15, 2026, Amendment 59 will be available on the NASA research opportunity homepage and SARA's ROSES blog. This ensures that researchers and the public can easily access the updated information and stay informed about the evolving landscape of space and earth sciences research.

In conclusion, Amendment 59 to ROSES-25 is a crucial step in ensuring that NASA's research efforts remain dynamic and responsive to changing priorities. It highlights the agency's commitment to transparency and collaboration with the scientific community. As we navigate the implications of these updates, one thing is certain: the future of space and earth sciences research is an exciting and ever-evolving journey.
