The Nuclear Spectroscopic Telescope Array Mission Overview and First Results

The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 13 June 2012, is the first focusing high-energy X-ray telescope in orbit. NuSTAR operates in the band from 3 -- 7 keV, extending the sensitivity of focusing far beyond the ~1 keV high-energy cutoff achieved by all previous X-ray satellites. The inherently low-background associated with concentrating the X-ray light enables NuSTAR to probe the hard X-ray sky with a more than one-hundred-fold improvement in sensitivity over the collimated or coded-mask instruments that have operated in this bandpass. In this talk I will provide an overview of the mission, discuss the in-flight performance, and present some results from observations of Active Galaxies, the Galactic Center, and supernova remnants.
