NASA launches satellite to study carbon pollution in the atmosphere


Vandenberg Air Force Base, CA (CNN) -- NASA launched a satellite to study climate change on Wednesday, shooting the Orbiting Carbon Observatory-2 (OCO-2) into space.

The liftoff from Vandenberg Air Force Station, California, was originally scheduled for Tuesday but was scrubbed because of a water flow issue in the launch pad.

With OCO-2, NASA is attempting to achieve a "vantage point" from space to study atmospheric carbon dioxide.
