NASA will hold a media briefing at 9 a.m. PDT (12 p.m. EDT) on Tuesday, March 13, to discuss the upcoming launch of the Nuclear Spectroscopic Telescope Array.

Technicians at Vandenberg Air Force Base in central California are placing the two halves of the rocket nose cone, or fairing, around NASA's Nuclear Spectroscopic Telescope Array, in preparation for its launch.

NASA's Nuclear Spectroscopic Telescope Array is being mated, or attached, to its Pegasus XL rocket today at Vandenberg Air Force Base in central California.

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, mission arrived at Vandenberg Air Force Base in California this morning after a cross-country trip by truck from the Orbital Sciences Corporation's manufacturing plant in Dulles, Va.

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, shipped to Vandenberg Air Force Base, Calif., on Tuesday, to be mated to its Pegasus launch vehicle.

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 recently confirmed that the Nuclear Spectroscopic Telescope Array, or NuSTAR, mission will launch in August 2011.

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.
