After it launches in 2011 aboard a Pegasus rocket, NuSTAR will give scientists an unprecedented view of high-energy X-rays coming from supernova remnants, black holes, blazars, and other extreme cosmic phenomena.
NASA has made a decision to restart an astronomy mission that will have greater capability than any existing instrument for detecting black holes in the local universe.
The selected proposals were among 29 SMEX and eight mission-of-opportunity proposals originally submitted to NASA in May 2003 in response to an Explorer Program Announcement of Opportunity issued in February 2003.
