South African entrepreneur Elon Musk launched his new rocket, the Falcon Heavy, from the Kennedy Space Center in Florida on 6 February. It is designed to deliver a maximum payload to low-Earth orbit of 64 tonnes - the equivalent of putting five London doubledecker buses in space. For this experimental and uncertain mission, however, he decided on a much smaller and whimsical payload - his old cherry-red Tesla sports car. A spacesuited mannequin was strapped in the driver's seat and the radio set to play a David Bowie soundtrack on a loop. The Tesla and its passenger have been despatched into an elliptical orbit around the Sun that reaches out as far as the Planet Mars.
