OCO-2 Booster on Stand

VANDENBERG AIR FORCE BASE, Calif. – Workers in the environmental enclosure, or clean room, at the top of the mobile service tower at Space Launch Complex 2 on Vandenberg Air Force Base in California steady the upper end of the United Launch Alliance Delta II rocket for NASA's Orbiting Carbon Observatory-2 mission, or OCO-2, as work platforms move into position around it. Launch is scheduled for July 2014. The observatory will collect precise global measurements of carbon dioxide in the Earth's atmosphere and provide scientists with a better idea of the chemical compound's impacts on climate change. Scientists will analyze this data to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important atmospheric gas.
