Satellite To Measure Greenhouse Gas Prepared For July 1 Launch

In this handout provided by the National Aeronautics and Space Administration (NASA), the United Launch Alliance Delta II rocket with the Orbiting Carbon Observatory-2 (OCO-2) satellite onboard, is seen as the launch gantry is moved at the Space Launch Complex 2 on June 30, 2014 at Vandenberg Air Force Base, California. OCO-2 will measure the global distribution of carbon dioxide, the leading human-produced greenhouse gas believed to drive changes in Earth's climate. OCO-2 is set for a July 1 launch.
