Sentinel-5 Precursor

Sentinel-5 Precursor, usually called Sentinel-5P, is a European Earth observation satellite developed by the European Space Agency for the Copernicus Programme. It was launched in October 2017 on a Rokot rocket from Plesetsk and was designed for a seven year life, bridging the gap in observations between Envisat and the later Sentinel-5 instruments. ESA selected Astrium UK, now part of Airbus Defence and Space, as prime contractor for the satellite in December 2011. The spacecraft is built on a hexagonal Astrobus L 250 satellite bus and carries a single instrument, the TROPOspheric Monitoring Instrument, which measures ozone, methane, formaldehyde, aerosol, carbon monoxide, nitrogen dioxide and sulphur dioxide in the atmosphere.
