The Orbital Sciences L-1011 known as "Stargazer" awaits the Orbital Sciences Pegasus XL rocket with its NuSTAR spacecraft. The Pegasus will launch NuSTAR into space where 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.
