The Carbon Mapper imaging spectrometer, which will measure the greenhouse gases methane and carbon dioxide from space, sits at NASA's Jet Propulsion Laboratory in Southern California in August 2023, before its September shipment to Planet Labs PBC in San Francisco. The instrument will be integrated into a Tanager satellite.

Designed and built by JPL, imaging spectrometer will be part of an effort led by the nonprofit Carbon Mapper organization to collect data on greenhouse gas point-source emissions. The information will help locate and quantify "super-emitters" – the small percentage of individual sources responsible for a significant fraction of methane and carbon dioxide emissions around the world.
