For the second time, NASA has had to scrub an attempt to put a new carbon-tracking satellite into space. Tuesday's try for the Orbiting Carbon Observatory, dubbed OCO-2, was aborted at 2:56am with less than one minute before launch. OCO-2 is designed to circle Earth from pole to pole, mapping CO2 behavior on a grid similar to the globe's lines of longitude. KQED Science Editor Craig Miller joins us from Vandenberg Air Force Base.
