The European Space Agency has launched the first satellite capable of measuring the wind speed on the surface of the Earth from space. The satellite, Named Aeolus after the ruler of the winds in Greek mythology, was built in the UK and was launched from an ESA facility in Kourou in French Guiana. Aeolus is expected to improve weather prediction models by using lasers to track winds on the Earth up to 30km into the stratosphere. Image: Twitter / @esa
