Detecting cow burps from space

In March 2024, a satellite built to detect the potent greenhouse gas methane launched into orbit – backed by New Zealand to a final total of $32 million. MethaneSAT aimed to pinpoint large leaks from oil and gas fields, since plugging these is considered an easy climate win. But an add-on mission was investigating whether the satellite could pick up the smaller, more diffuse methane emissions from agriculture. Our Changing World joined the New Zealand-based team testing this capability – before disaster struck. With MethaneSAT uncontactable and lost in space, what did the mission deliver?

This episode was updated on 6 October to include the correct total figure of the New Zealand's contribution to MethaneSAT of $32 million.
