At Vandenberg Air Force Base in California, the second stage of the Pegasus XL rocket that will launch the Nuclear Spectroscopic Telescope Array (NuSTAR) to orbit is ready to move from a jackable rail to a stationary one for processing in Building 1555. After the rocket and spacecraft are processed at Vandenberg, they will be shipped to the Ronald Reagan Ballistic Missile Defense Test Site located at the Pacific Ocean’s Kwajalein Atoll for launch.
The high-energy X-ray telescope will conduct a census for black holes, map radioactive material in young supernovae remnants, and study the origins of cosmic rays and the extreme physics around collapsed stars. Photo credit: NASA/Randy Beaudoin, VAFB
