Aeolus standing proud for testing

As part of the campaign to launch ESA's Aeolus satellite on 21 August, the satellite is held in a vertical position, allowing engineers to access the different components. Since the satellite's arrival in Kourou, French Guiana, on 28 June, it has been 'functionally tested'. This included tests on the pressure of the propulsion tanks, piping, valves, filters and thrusters.
