1. Elon Musk
The founder of Tesla and former CEO of Paypal, Musk is worth approximately US$20 billion. SpaceX, which he founded in 2002, designs, manufactures and launches rockets and spacecraft. Its core business is launching satellites and transporting cargo to the ISS for Nasa. Currently, SpaceX is refining its Dragon capsule to enable it to fly people to the ISS, with the first manned test flight expected within six months to a year.
But the ultimate goal? To dramatically reduce the cost of space travel by developing reusable booster rockets and capsules, with the ultimate goal of making us a “multi-planetary species.” Musk wants to colonise Mars to protect the human race from extinction.
