An Orbital Sciences’ Pegasus rocket and NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, are installed under Orbital’s L-1011 carrier aircraft awaiting departure from Vandenberg Air Force Base in California for the U.S. Army's Ronald Reagan Ballistic Missile Defense Test Site on Kwajalein Atoll, part of the Marshall Islands in the Pacific Ocean.
The Pegasus, mated to its NuSTAR payload, will be launched from the carrier aircraft 117 nautical miles south of Kwajalein at latitude 6.75 degrees north of the equator. The high-energy X-ray telescope will conduct a census of black holes, map radioactive material in young supernovae remnants, and study the origins of cosmic rays and the extreme physics around collapsed stars. Launch is scheduled for June 13. For more information, visit http://www.nasa.gov/nustar. Photo credit: NASA/Randy Beaudoin, VAFB
