Airbus has built a giant sand pit in Stevenage to mimic the surface of Mars. The indoor terrain, about the size of a basketball court, will be used to test systems on the rover that Europe will send to the Red Planet in 2018.
ExoMars, as it is known, will be a six-wheeled robot tasked with finding signs of past or present life.
