Included on board the 10ft-long (3m) rover is a machine that has turned the thin, carbon dioxide-rich Martian air into oxygen and a helicopter the size of a tissue box that made the first-ever powered, controlled flight on another planet. Perseverance – the car-sized rover that safely touched down on the Martian surface on 18 February this year – might only have a top speed of less than 0.1 miles per hour (152m/hr), but it carries a wide range of tools, instruments, and experiments that have already made some groundbreaking achievements. Trundling across the surface of Mars as you read this is a remarkable machine.
