NASA ROSES-2025 Amendment 26: Final Guidelines for Astrophysics Data Analysis Program Released

The latest update to NASA’s Research Opportunities in Space and Earth Sciences (ROSES-2025) has just been released, and it promises exciting opportunities for researchers in astrophysics. Amendment 26 finalizes the text for the Astrophysics Data Analysis Program (ADAP), providing clear deadlines, updated submission guidelines, and the scope of eligible data. For scientists aiming to maximize the scientific return on NASA’s missions, this amendment clarifies how archival data from space observatories like Euclid, SPHEREx, and Chandra can be leveraged for innovative investigations.

Summary of Amendment 26

Amendment 26 to ROSES-2025 officially releases the final guidelines for the D.2 Astrophysics Data Analysis Program (ADAP). ADAP is designed to fund research that focuses on analyzing archival data from NASA’s space astrophysics missions, ensuring that the wealth of observational data collected over the years is fully utilized. The amendment specifies key dates: optional Notices of Intent (NOIs) are due by December 19, 2025, while full proposals must be submitted by January 30, 2026.

Eligible datasets include fully public Euclid mission data available by the proposal deadline, including Early Release Observations and Quick Release 1. Additionally, SPHEREx regular data releases and archival data from Chandra X-ray observatory may serve as primary sources for ADAP proposals.

Significant changes have been made to streamline submissions. Documents previously required for the “Expertise and Resources” section of proposals are now requested only after provisional selections. Budget submissions have been simplified; only a single-page justification is required, eliminating the need for NSPIRES-based budgets or Total Budget files. Proposals must specify duration and cost category (small, medium, or large).

The amendment is expected to be posted around November 26, 2025, on NASA’s ROSES-2025 solicitation page and on SARA’s ROSES blog. Questions can be directed to Pablo Saz Parkinson and Joshua Pepper via their official NASA emails.

What Undercode Say: Strategic Implications for Astrophysics Researchers

The finalization of ADAP under Amendment 26 is a strategic win for astrophysics researchers, particularly those interested in archival data exploitation. By clearly defining eligible datasets, NASA is incentivizing proposals that mine high-value, previously under-analyzed data. This approach aligns with a broader scientific trend: maximizing the return on expensive space missions by encouraging secondary analyses that might reveal unexpected insights.

Euclid’s Early Release Observations and Quick Release 1 datasets present unique opportunities for cosmological studies. Researchers can propose investigations on large-scale structure formation, dark energy constraints, or galaxy evolution using these datasets long before they are widely analyzed by other teams. Similarly, SPHEREx’s data will provide multi-wavelength insights, enabling new research avenues in star formation, exoplanet studies, and interstellar medium characterization.

Chandra archival data remains a goldmine for high-energy astrophysics. With reduced submission requirements for expertise documentation and simplified budget formats, the barrier to entry for smaller teams or early-career scientists is lowered, democratizing access to NASA funding. Researchers can now focus on the scientific merit of proposals rather than administrative complexities.

Another subtle but important implication is the explicit encouragement of using a single primary source of data, such as Chandra. This reinforces NASA’s support for focused, high-quality analyses over diffuse, multi-source investigations that might dilute research impact.

The deadline structure also allows a clear timeline for planning. By requesting optional NOIs, NASA can gauge interest and prepare reviewers ahead of full proposal submission. The early communication with NASA contacts ensures that researchers can clarify eligibility or dataset questions, further reducing wasted effort.

In summary, Amendment 26 represents a shift toward efficiency, inclusivity, and scientific leverage. Researchers who strategically select datasets, focus on achievable goals within the cost and duration categories, and exploit NASA’s streamlined submission process are likely to maximize both funding success and scientific impact.
