The Nuclear Spectroscopic Telescope Array, or NuSTAR, is a pathfinder mission that will study the sky through high energy X-rays.
NuSTAR is a part of NASA's Explorer Program. The program provides frequent, low-cost access to space for missions with small- to mid-sized spacecraft. NuSTAR originally was selected from proposals submitted in response to an announcement of opportunity in 2003. Fiona Harrison of the California Institute of Technology, Pasadena, is the NuSTAR principal investigator.
NASA expects to select three additional Small Explorer missions for flight in the first half of the next decade through a competitive selection within the astrophysics and heliophysics scientific communities.
