As engineers are preparing EarthCARE for its life in orbit, the satellite is being put through its paces at ESA testing facilities in the Netherlands – the largest satellite test facility in Europe, equipped to simulate every aspect of the space environment. One of the first tests involved the deployment of the satellite’s 11 metre solar wing from its folded stowed configuration, which allows it to fit in the rocket fairing, to its fully deployed configuration as it will be in orbit around Earth.
