English: At Vandenberg Air Force Base in California, a worker secures a crane on the Taurus XL Stage 0 motor. The motor will be lifted onto a flatbed truck and transported to Orbital Sciences' Hangar 1555. The Taurus XL will launch NASA's Orbiting Carbon Observatory, or OCO, spacecraft targeted for Jan. 15. The OCO is a new Earth-orbiting mission sponsored by NASA's Earth System Science Pathfinder Program.
