SpaceX is Musk's attempt to do that something. Its headquarters are situated within earshot of the busy runways of Los Angeles International airport. The company's logo stands proudly on an otherwise nondescript hangar-sized building. But inside, a revolution in space travel could be taking place.
The factory floor has been roughly organised into an assembly line to make space rockets, part of a process of wresting the future of space travel out of the hands of government bodies, such as Nasa, and into the hands of private businesses. 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.
That is stunning stuff. 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 is not alone in aiming for the stars. A raft of private firms have joined in a new space race. Jeff Bezos, founder of Amazon, is building a suborbital rocket called the Blue Origin New Shepard. John D Carmack, the man behind video games Doom and Quake, has his eyes on a lunar landing. Virgin Atlantic boss Richard Branson is aiming to kickstart space tourism with his Virgin Galactic project. Yet SpaceX is the most advanced and ambitious. Its rockets have already flown into space and it has won hundreds of millions of dollars worth of business contracts for future voyages.
