NASA Science Update: ROSES-25 Amendment 59 - What You Need to Know (2026)

NASA's ROSES-25 program, an ongoing 'omnibus' solicitation, has undergone significant amendments with the release of Amendment 59. This update is a crucial development for researchers and scientists, as it reflects the agency's evolving priorities and the broader administrative changes within the federal government. The amendment introduces several key changes, each with far-reaching implications for the space and Earth sciences community.

A Shift in Allowable Costs

One of the most notable aspects of Amendment 59 is its impact on allowable costs. The amendment proposes substantial revisions to 2 CFR 200, the government-wide guidance for grants and cooperative agreements. Effective October 1, 2026, many types of currently allowable costs may be restricted or denied. This includes publications, research or events outside the United States, and domestic conferences. Such changes could significantly impact the operational and budgetary planning of research projects.

What makes this particularly fascinating is the potential for these revisions to reshape the landscape of scientific research. For instance, the restriction on international research or events could limit the opportunities for collaboration and knowledge exchange, which are vital for advancing scientific understanding. This raises a deeper question: How will these changes affect the global scientific community, and what alternative strategies might researchers adopt to maintain their international partnerships?

The Role of Public Comments

The amendment also emphasizes the importance of public engagement. Public comments on the revisions to 2 CFR 200 are being accepted until July 13, 2026. This is a critical step in ensuring that the changes are well-informed and responsive to the needs of the scientific community. What many people don't realize is that this process is not just about compliance; it's an opportunity for scientists and researchers to have a direct impact on the policies that shape their work.

The Impact on NASA's Priorities

The amendment's updates are aligned with NASA's and the administration's priorities, as outlined in Sections I, I(g), II(a), II(b), III(b), III(d), V(b)ii, VI(c), and VIII(b). This means that the changes are not arbitrary but are designed to support specific goals and objectives. From my perspective, this is a strategic move that demonstrates NASA's commitment to aligning its research programs with broader national priorities.

Looking Ahead

As we move forward, it's essential to consider the potential future developments that may arise from these amendments. For instance, how might the restrictions on international travel and events impact the planning of space missions or Earth science projects that require global collaboration? What alternative mechanisms might be put in place to facilitate international cooperation?

In conclusion, Amendment 59 to ROSES-25 is a significant development that will have a profound impact on the space and Earth sciences community. It reflects the agency's evolving priorities and the broader administrative changes within the federal government. As researchers and scientists, it is crucial to stay informed about these changes and to engage in the public comment process to ensure that our voices are heard. Personally, I think that this amendment is a critical step in shaping the future of scientific research, and I am eager to see how the community responds to these challenges and opportunities.
