NuSTAR (Nuclear Spectroscopic Telescope Array)

NuSTAR (Nuclear Spectroscopic Telescope Array) is a space-based X-ray telescope that uses a Wolter telescope to focus high energy X-rays from astrophysical sources, especially for nuclear spectroscopy, and operates in the range of 5 to 80 keV.[3] It is the eleventh mission of the NASA Small Explorer satellite program (SMEX-11) and the first space-based direct-imaging X-ray telescope at energies beyond those of the Chandra X-ray Observatory and XMM-Newton. It was successfully launched on 13 June 2012, having previously been delayed from 21 March due to software issues with the launch vehicle.

Its primary scientific goals are to conduct a deep survey forblack holes a billion times more massive than the sun, understand how particles are accelerated to within a fraction of a percent below the speed of light in active galaxies, and understand how the elements are created in the explosions of massive stars by imaging the remains, which are called supernova remnants.
