A pollution monitoring satellite built in Stevenage is being launched today from Russia to monitor pollution levels across the globe.
It comes after a World Health Organisation warning that pollution is a greater global threat than Ebola and HIV.
The satellite, Sentinel-5 Precursor, will be able to map a number of gases including nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane, carbon monoxide and aerosols.
Scientists hope it will give a global picture of where the situation is worst, and which countries and industries our pumping out the most pollution.
