What NASA announced
NASA’s 4 September 2026 announcement says ROSES-2025 Amendment 70 releases D.4 TCAN as a new opportunity in the ROSES-25 program. The agency describes TCAN’s purpose and focus; these are program statements rather than independently assessed outcomes. [1]
- NASA says the program is intended for coordinated work in fundamental theory and computational techniques that goes beyond individual-investigator projects.
- Its stated goals include collaborative networks crossing institutional and geographical boundaries and training future theoretical and computational scientists.
- NASA describes the opportunity as focused on time-domain multi-messenger astrophysics and integrated modeling tools for multi-messenger phenomena.
04
Network model described by NASA
NASA says proposed networks are expected to include participants with different relevant specialisms. It encourages, rather than guarantees or requires in the supplied announcement, collaboration spanning multiple sectors. [1]
- NASA expects proposing networks to combine complementary expertise, which it says may include astrophysics, gravitational physics, nuclear physics, plasma physics, computational mathematics, numerical methods and algorithms, software engineering, and observational astronomy.
- The agency encourages multidisciplinary collaboration across sectors, including academic institutions, national laboratories, and private organizations.
05
Deadlines and missing details
The announcement gives two dates but does not state submission times or time zones. Applicants should not infer eligibility or submission requirements from the announcement alone: the supplied record does not specify them. [1]
- Mandatory Notice of Intent: 15 October 2026.
- Proposal deadline: 3 December 2026.
- NASA identifies NSPIRES as its relevant solicitation and proposal system, but the supplied material does not provide a direct D.4 application link.

What interested applicants can do
The NASA announcement provides planning dates, but not the full application record or participation rules.
- 01
Record 15 October 2026 as the mandatory Notice of Intent deadline and 3 December 2026 as the proposal deadline.
- 02
Use NASA’s linked NSPIRES resource to locate the underlying solicitation before preparing a submission.
- 03
Confirm eligibility, award terms, required materials, submission procedures, and deadline time zone from the full solicitation.
- 04
Assess whether a proposed network brings together complementary expertise relevant to multi-messenger astrophysics.
