VANDENBERG AIR FORCE BASE, Calif. -- Inside the Astrotech payload processing facility at Vandenberg Air Force Base in California, Orbital Sciences technicians conduct an ultraviolet light cleanliness inspection on the payload load isolators of the Taurus XL launch vehicle for the Orbiting Carbon Observatory, or OCO, before installation on the ballast ring. From left are Dana Frederic, Bill Nelson and Randy Bone. The OCO is an Earth-orbiting mission sponsored by NASA's Earth System Science Pathfinder Program. The observatory will collect precise global measurements of carbon dioxide in the Earth's atmosphere. Scientists will analyze the data returned to better understand the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas. Launch is targeted for Feb. 24 from Space Launch Complex 576-E at Vandenberg. Photo credit: NASA/Richard Nielsen, KSC
