NuSTAR, Meet Rocket

At Vandenberg Air Force Base's processing facility in California, the separation ring on the aft end of NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, at right, inches its way toward the third stage of an Orbital Sciences Pegasus XL rocket under the watchful eye of a member of the Orbital Sciences technical team.

Pegasus Rocket Carrying the Nuclear Spectroscopic Telescope Array

An Orbital Sciences Corporation owned L-1011 "Stargazer? takes-off with a Pegasus rocket carrying the Nuclear Spectroscopic Telescope Array satellite here Tuesday, June 5, 2012. The NuSTAR satellite will image high-energy X-rays, giving scientists a new perspective on black holes, supernovae and galactic nuclei.
