Workers unlatch the crane that lowered Stage 0 of the Orbital Sciences Corp. Taurus XL into launch position on Space Launch Complex 576-E at Vandenberg Air Force Base in California. As part of the four-stage Taurus XL rocket that will carry NASA's Glory spacecraft into low Earth orbit, stages 1, 2 and 3 will join Stage 0 at the launch pad about a week later.

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/Don Kosoksa, VAFB
