Amendment 76: D.3 AGIGO: NuSTARGeneral Observer Second Opportunity in ROSES-25.
The Nuclear Spectroscopic Telescope Array (NuSTAR) General Observer (GO) Program solicits proposals for basic research relevant to the NuSTAR mission. NuSTAR Cycle 13 will commence on or about June 1, 2027, and last for a nominal period of 12 months. The total amount of time allocated to General Observers during NuSTAR Cycle 13 is expected to be 11.7 Ms (73% of the total available observing time), of which 8.5 Ms will be allocated to NuSTAR observations selected through this program element.
On or about October 1, 2026, ROSES-25 Amendment 76 announces the second opportunity to propose to the NuSTAR General Observer (GO) program in ROSES-25. The due date for Phase-1 Proposals (submitted via ARK RPS) is January 28, 2027. The text for this new opportunity may be found in the new Section 11 of D.3 Combined General Investigator General Observer Program.
