The threat was invisible to the eye: tons of methane billowing skyward, blown out by natural gas pipelines snaking across Siberia. In the past, those plumes of potent greenhouse gas released by Russian petroleum operations last year might have gone unnoticed. But armed with powerful new imaging technology, a methane-hunting satellite sniffed out the emissions and tracked them to their sources.

Thanks to rapidly advancing technology, a growing fleet of satellites is now aiming to help close the valve on methane by identifying such leaks from space. The mission is critical, with a series of recent reports sounding an increasingly urgent call to cut methane emissions. Continue reading →
