The world's biggest methane producers could be identified from space after a climate group created a satellite to detect and track greenhouse gas "super emitters".
Non-profit organisation Carbon Mapper planned to launch the satellite, which is smaller than a bar fridge, on a SpaceX rocket in California early on Friday morning.
The satellite will be one of two tracking methane, which is the second most common greenhouse gas in the atmosphere and makes a significant contribution to global warming.
