VANDENBERG AIR FORCE BASE, Calif. – The transporter for the Orbital Sciences Pegasus XL rocket juts through the open door of Orbital’s hangar at Vandenberg Air Force Base in California. The rocket is mated to NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, encapsulated in the Pegasus payload fairing. The transporter will move them to the runway ramp where they will be attached to the underside of Orbital’s L-1011 carrier aircraft. The aircraft will fly the pair from Vandenberg to the Ronald Reagan Ballistic Missile Defense Test Site on the Pacific Ocean’s Kwajalein Atoll for launch. A revised launch date will be set at the Flight Readiness Review, planned for later this week. 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.
