As part of the series of tests being carried out at Intespace in Toulouse, France, the Aeolus satellite has been given a ‘fit check’ to see that it can be connected to its Vega rocket. Aeolus will be launched from Europe’s Spaceport in French Guiana in the autumn of 2018. Carrying pioneering ultraviolet lasers, never before flown in space, Aeolus will provide slices through the world’s winds along with information on aerosols and clouds.
