Share Radio's technology expert Steve Caplin lets us hear the first ever audio from Mars. He brings news of airless tyres developed from NASA tech, of a virtual Mars house sold for $0.5m, an invisible security keypad, robot lifeguards, a car using your phone as its dashboard, a foolproof Face ID system for phones, the archive of Douglas Adams's letters called - perhaps not surprisingly - 42 and the launch of clothes made from mushroom leather.
