A European satellite built to map Earth’s air like never before will launch into space early Friday (Oct. 13), and you can watch it live online.
The Sentinel-5P satellite of the European Space Agency (ESA) is scheduled to lift off aboard a Rockot launch vehicle at 5:27 a.m. EDT (0927 GMT) from the Plesetsk Cosmodrome in northern Russia.

Sentinel-5P (the “P” stands for “Precursor”) is designed to track global air pollution from orbit in unprecedented detail. The satellite is part of the European Union’s Copernicus program for Earth-monitoring missions, but it is the first dedicated to creating a global map of air quality every 24 hours.
At the heart of Sentinel-5P is Tropomi (short for Tropospheric Monitoring Instrument), which will map air quality along a swath 1,801 miles (2,900 kilometers) wide from an orbit 512 miles (824 km) above Earth. The instrument will monitor trace gases that affect the air we breathe, such as nitrogen dioxide, ozone, formaldehyde, sulfur dioxide, methane, carbon monoxide and aerosols, according to an ESA mission description .

“Every day, Tropomi will make almost 20 million observations of important air pollutants and gases affecting the climate,” Pepijn Veefkind from the Royal Netherlands Meteorological Institute (KNMI) said in a recent statement . “KNMI will use this data to improve air-quality forecasts and to keep a close eye on emission increases or reductions, and to monitor what mitigation measures are effective in protecting the air we breathe.”
The Sentinel-5P satellite is designed for a mission life of about seven years but carries enough fuel to last a decade, ESA officials said.
