He wants to secure humanity’s future by turning the human race into a space-faring people able to colonise other planets. It’s the only way, Musk believes, that we can be saved, either from destroying ourselves or from some outside calamity. To put it mildly, Musk thinks big and takes the long view. “It’s important that we attempt to extend life beyond Earth now,” he says in an accent hinting at his childhood in South Africa. “It is the first time in the four billion-year history of Earth that it’s been possible and that window could be open for a long time – hopefully it is – or it could be open for a short time. We should err on the side of caution and do something now.”

Using its hyper-efficient Merlin engines, SpaceX has successfully flown its first rocket, Falcon 1, up into space, where it put a satellite into orbit. Then it successfully flew the much bigger Falcon 9 rocket earlier this year. Now the company is working on Dragon, a space capsule that will sit on top of a Falcon 9 and deliver first cargo – and then, hopefully, astronauts – to the International Space Station.
SpaceX, which was only founded in 2002, is not even a decade old. Yet it is doing things in space that some countries with their own national space programmes have not yet achieved. “When we launched the initial rocket actually leaving the launch pad, that was awesome,” Musk says, gazing at the Dragon module being built. “Getting into orbit was when a lot of people thought: OK, it’s real. That’s something that South Korea tried a couple of times and they failed. Brazil tried three times and they failed. This is normally something a country does, and only a few countries have succeeded.”

SpaceX’s Merlin engines are beautifully engineered and powerful, but simply made. They run on highly refined kerosene that costs less than petrol. The rockets they power – in the shape of the Falcon 1 and Falcon 9 – are also simple. They have fewer stages (where one bit of the rocket separates from the other) than their rivals and are mostly re-usable. Thus they can put cargo into space for a fraction of the cost.
The Dragon module is also a throwback. It looks nothing like the space shuttle, which it essentially hopes to replace as the “taxi” service to the International Space Station. Instead, it resembles something from the 60s, being shaped like a shuttlecock.
…through it all is the desire to colonise Mars. Musk insists that his most powerful Falcon 9 rockets could already launch missions to Mars if assembled in Earth’s orbit. He wants SpaceX to help humanity spread into space, just like the first European explorers setting out for the New World. “One of the long-term goals of SpaceX is, ultimately, to get the price of transporting people and product to Mars to be low enough and with a high enough reliability that if somebody wanted to sell all their belongings and move to a new planet and forge a new civilisation they could do so.”
