Amendment 80: D.3 AGIGO: Swift, Fermi, and TESS Observatories Second Opportunities in ROSES-25

On October 20, 2026, the National Science Foundation announced Amendment 80 to the ROSES-25 budget, which introduces second opportunities for investigators to propose research to the Swift, Fermi, and Transiting Exoplanet Survey Satellite (TESS) General Investigator programs. These General Investigator programs offer funding for basic research relevant to each respective mission.

Swift Cycle 23 is scheduled to commence on or around July 1, 2027, and will last for a nominal period of 12 months. Proposed investigations may cover a wide range of astrophysical topics, including Theoretical GRB and non-GRB Investigations, Other Correlative Investigations, and New Swift GRB Projects. Proposals for archival data-analysis investigations utilizing Swift data are also welcome.

Fermi Cycle 20 is set to begin approximately 5 to 10 months after the Phase-1 Proposal due date, with a nominal duration of 12 months (3 years for large proposals). The Fermi General Investigator program aims to support various scientific pursuits, such as utilizing Fermi data, conducting correlative observations across different wavelengths, developing data analysis methods applicable to Fermi data, and carrying out theoretical research relevant to Fermi observations.
