Over the last six months, engineers at Airbus in Stevenage, UK, and teams from Europe and North America have turned a multitude of structural parts and electronic units into a complete satellite: ESA’s Biomass satellite. Now complete, this brand-new satellite has been shipped to Airbus’ testing facility in Toulouse, France, where it will be put through its paces to ensure that it will survive the rigours of liftoff and the harsh environment of space to deliver on its promise, that being to yield new insight into Earth’s precious forests.
