NuSTAR Proposals and Tools

While NuSTAR was initially approved by NASA as a 2-year Principal Investigator-led (PI-led) mission, NuSTAR has now been approved to continue operations through 2018 (subject to review by the 2016 NASA Astrophysics Senior Review of Operating Missions) and to have a dedicated Guest Observer (GO) Program. There are several opportunities for guest observers in the general scientific community to propose for NuSTAR observations.
