VANDENBERG AIR FORCE BASE, Calif. – Workers lower the interstage adapter, or ISA, for NASA's Orbiting Carbon Observatory-2 mission, or OCO-2, toward a transportation hardware cradle in the high bay of the Building 836 hangar on Vandenberg Air Force Base in California. OCO-2 is scheduled to launch aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 in July. The ISA is the interface between the Delta II first and second stages. The second stage engine fits within the ISA. 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.
