NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) will be the first sensitive, focusing high energy X-ray telescope to orbit the Earth. NuSTAR will investigate the hottest regions in the Universe, studying sources ranging from neutron stars to supernovae to black holes and the Sun. Because of its focusing optics and improved detectors, NuSTAR will be sensitive to objects one hundred times fainter than any previous mission working at these energies. Developed by an international team, this Small Explorer mission will launch in 2012, and spend at least two years observing the high energy Universe.
