This Jan. 22, 2014, artist concept rendering provided by NASA shows their Orbiting Carbon Observatory (OCO)-2. The OCO-2, managed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., will launch from Vandenberg Air Force Base, Calif., on a Delta II rocket on July 1, 2014. Five years after a NASA satellite to track carbon dioxide plunged into the ocean after liftoff, the space agency is launching a carbon copy _ this time on a different rocket. The $468 million mission is designed to study the main driver of climate change emitted from smokestacks and tailpipes. (AP Photo/NASA/JPL-Caltech) less
