NASA’s first spacecraft dedicated to measuring carbon dioxide levels in Earth’s atmosphere will launch in July from Vandenberg Air Force Base, California.
The Orbiting Carbon Observatory-2 (OCO-2) mission will provide a more complete, global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored. Carbon dioxide, a critical component of Earth’s carbon cycle, is the leading human-produced greenhouse gas driving changes in Earth’s climate.
“Carbon dioxide in the atmosphere plays a critical role in our planet’s energy balance and is a key factor in understanding how our climate is changing,” said Michael Freilich, director of NASA’s Earth Science Division in Washington. “With the OCO-2 mission, NASA will be contributing an important new source of global observations to the scientific challenge of better understanding our Earth and its future.”
