A United Launch Alliance (ULA) Delta II rocket carrying the Orbiting Carbon Observatory-2 (OCO-2) payload for NASA lifts off from Space Launch Complex-2. This launch marks the 51st Delta II mission for NASA and Delta II's return to flight as the first of two planned Delta II launches this year. Orbiting Carbon Observatory-2 (OCO-2) will be NASA's first dedicated Earth remote sensing satellite to study atmospheric carbon dioxide from Space. OCO-2 will be collecting space-based global measurements of atmospheric CO2 with the precision, resolution, and coverage needed to characterize sources and sinks on regional scales.
