An artist's concept depicts one of the Carbon Mapper Coalition's Tanager satellites, which will use imaging spectrometer technology developed at NASA's Jet Propulsion Laboratory in Southern California to measure methane and carbon dioxide point-source emissions, down to the level of individual facilities and equipment, on a global scale.

The Tanager-1 satellite, launched from Vandenberg Space Force Based in California on Aug. 16, 2024, was developed as part of a philanthropically funded public-private coalition led by the nonprofit Carbon Mapper. JPL and Planet Labs PBC, which built Tanager-1, are both members of the Carbon Mapper Coalition. The group plans to launch a second Tanager satellite, called Tanager-2, also being built by Planet Labs and equipped with a JPL-built imaging spectrometer.
