Elon Musk reveals how he wants to colonise Mars – video

SpaceX, Elon Musk's project to colonise Mars, has released a video demonstrating his hopes for space travel. Musk has said that he wants to make it possible for 'anyone who wanted to go' to Mars to be able to get there but predicts it could take between 40 and 100 years to establish a large colony of people. The new rocket involved in this would be the largest in history.
