ROSES-19 Amendment 46: This amendment releases final text for program element D.9, Cycle 6 of the NuSTAR General Observer (GO) Program.


The NuSTAR General Observer (GO) Program solicits proposals for basic research relevant to the NuSTAR mission. Observing time will be made available to scientists at both U.S. and non-U.S. institutions. Individuals may submit proposals for three general types of observations: “standard-mode”, “Target-of-Opportunity” (ToO, see Section 1.3.4), and “Large Programs” (LP, see Section 1.3.5).


In addition to investigations utilizing NuSTAR observations only, proposals involving coordinated observations with the European Space Agency (ESA)/NASA X-ray Multi-Mirror Mission (XMM)-Newton X-ray observatory, NASA’s Neil Gehrels Swift observatory, and NASA’s Neutron star Interior Composition ExploreR (NICER) mission are also solicited under this Call for Proposals.


Phase-1 proposals are due by 4:30 p.m. Eastern Time January 24, 2020 (via ARK/RPS). Major changes since last cycle include:


·         The Phase-1 proposal review will be done in a dual-anonymous fashion resulting in changes to how proposals are written (see Section 2.2.1 and the Guidelines for Anonymous Proposals) and

·         Proposals requesting that observations occur over two cycles may be submitted (see Section 1.3.2).


On or about October 25, 2019 this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2019” (NNH19ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on the RSS feed at:
