Amendment 23: D.5 Swift Cycle 19 Update on Joint Observations with NICER.

ROSES-2022 Program element D.5, the Neil Gehrels Swift Observatory General Investigator - Cycle 19 Program (D.5 Swift) solicits proposals for basic research relevant to the Swift gamma-ray burst mission. The primary goal of this mission is to determine the origin of gamma-ray bursts (GRBs) and use these bursts to probe the early Universe. Swift is also a valuable asset for obtaining multiwavelength images, spectra, and light curves on interesting Targets of Opportunity (ToOs) and other non-transient sources

ROSES-2022 Amendment 23  adds to D.5 Swift a new joint observing opportunity with the Neutron Star Interior Composition Experiment (NICER) mission. Programs requiring the use of both observatories to meet their primary science goals may now be awarded NICER observing time directly through the D.5 Swift. New text is in bold. The due date remains unchanged: Phase-1 proposals are due at 4:30 p.m. Eastern time via ARK/RPS by 09/22/2022.

On or about June 7, 2022, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2022" (NNH22ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on SARA's ROSES blog at:
