ESA's Tango mission will measure and monitor three greenhouse gases: methane, carbon dioxide and nitrogen dioxide being emitted from large industrial sites. Tango will comprise two 25-kg satellites orbiting in tandem: one configured to measure methane and carbon dioxide and one to measure nitrogen dioxide.
The mission will deliver high-resolution images of emission plumes as well as the surrounding pollution, with sufficient accuracy to determine emissions with a single observation.
