NASA's Orbiting Carbon Observatory (OCO) satellite has failed to reach orbit after "problems separating" from its launcher rocket. The space agency describes the launch as "not successful".

NASA has issued a brief statement, saying:

It appears that the satellite didn't achieve any kind of useful trajectory, with NASA describing the mission as "ended".

The two-year OCO plan would have seen the satellite's new spectrometers map atmospheric carbon around the globe to unprecedented levels of accuracy. It was thought that results from the OCO would remove much of the uncertainty and acrimony from the current debate on CO₂. ®
