The Taurus XL rocket's Stage 3 motor is moved to a stationary rail in a temporary processing tent.

At Vandenberg Air Force Base in California, the Taurus XL rocket's Stage 3 motor is moved to a stationary rail in a temporary processing tent near the pad at Space Launch Complex 576-E. Orbital Sciences' Taurus XL is a four-stage rocket that will carry NASA's Glory spacecraft into low Earth orbit. In early February, the spacecraft is scheduled to arrive at the pad, where it will be attached to the third stage and then stacked atop the remaining stages.

Once Glory reaches orbit, it will collect data on the properties of aerosols and black carbon. It also will help scientists understand how the sun's irradiance affects Earth's climate. Launch is scheduled for 5:09 a.m. EST Feb. 23. For information, visit www.nasa.gov/glory. Photo credit: NASA/Randy Beaudoin, VAFB
