Early on Monday morning, Nasa's Curiosity rover will attempt a hazardous landing on the Martian surface. It will take seven minutes from the capsule hitting the top of the atmosphere at six kilometres per second to the van-sized vehicle being placed gently on the ground.
A heat shield to withstand heating to 1,600C, the largest and strongest supersonic parachute yet built, and finally a new piece of kit called the Sky Crane will all be used.
