TopGear goes to the Moon
Posted: 20 May 2010
Underneath the Winnebago, the Rover has a fabulously capable chassis, nicknamed the ‘golden chariot' by the people at NASA. It has 12 wheels arranged in six pairs, all of which steer and have their own motor. So it's a 12-wheel-drive, all-wheel-steer machine. Each pair of wheels has its own suspension unit that allows them to climb over rocks while those on the other side drop into hollows. Like a spider picking its way over stones, with some legs perched high and others stretched low while its body stays level, it's perfect for the boulder-strewn lunar surface.
