Positioning NASA's OCO-2's Delta II Launch Vehicle Second Stage for Mating

The Delta II second stage for NASA's Orbiting Carbon Observatory-2 mission, or OCO-2, is positioned atop the rocket's first stage in the mobile service tower at Space Launch Complex 2 on Vandenberg Air Force Base in California. Operations are underway to mate the stages for launch. OCO-2 is scheduled to launch aboard a United Launch Alliance Delta II rocket in July. The rocket's second stage will insert OCO-2 into a polar Earth orbit. OCO-2 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.

OCO-2 is managed by JPL for NASA's Science Mission Directorate, Washington. Orbital Sciences Corporation, Dulles, Va., built the spacecraft and provides mission operations under JPL's leadership. The California Institute of Technology in Pasadena manages JPL for NASA.
