ALT Animated black and white sequence of a satellite antenna opening up in space. The footage shows a series of images of the different stages of the antenna opening from stowed to fully deployed. Just a week after its launch, ESA’s Biomass mission has reached another critical milestone on its path to delivering unprecedented insights into the world’s forests and their vital role in Earth’s carbon cycle – the satellite’s 12-metre-diameter antenna is now fully deployed. The photographs in this animated sequence come from a camera installed on the Biomass satellite and offer a rare glimpse into the action in space.
