(CBS News) Only four entities have put a space capsule in orbit and brought it back: the United States, Russia, China -- and Elon Musk. It is Musk's company, SpaceX, that launched that capsule to the space station today.
Musk is a man who does things others say are impossible. "CBS Evening News" anchor Scott Pelley recently spoke to him for "60 Minutes."
"I think we're at the dawn of a new era. And I think it's going to be very exciting," Musk said. "What we're hoping to do with SpaceX is to push the envelope and provide a reason for people to be excited and inspired to be human."
Elon Musk is 40, and worth about $2 billion. As a teenager, he wrote computer games in his native South Africa before heading to the U.S. and starting PayPal. He built an electric car company called Tesla. But his passion is space.

Pelley: Now tell me what's that big piece right up there?
Musk: That's the second stage of a Falcon Nine rocket.
Musk's California factory is filled with young engineers and NASA veterans. He plans to cut the cost of space flight by 90 percent.
Musk: The odds of me coming into the rocket business, not knowing anything about rockets, not having ever built anything, I mean, I would have to be insane if I thought the odds were in my favor.
Pelley: Why even begin?
Musk: When something is important enough, you do it even if the odds are not in your favor.
We came across a Dragon capsule like the unmanned one headed to the space station. The first thing we noticed were the windows
Pelley: But people don't put windows in cargo ships.
Musk: That's right. Exactly.
Pelley: So what that tells me is that this was never intended to be only a cargo ship.
Musk: No the Dragon was always designed to carry astronauts.
Eventually it could hold seven seats. But there are critics, including space heroes, who doubt the safety of a private company.
Pelley: Neil Armstrong, Gene Cernan have both testified against commercial space flight in the way that you're developing it. And I wonder what you think of that?
Musk: I was very sad to see that because those guys are -- yeah, you know, those guys are heroes of mine, so it's really tough. You know, I -- I wish they would come and visit, and see the hard work that we're doing here. And -- and I think that would change their mind.
Pelley: They inspired you to do this, didn't they?
Pelley: And to see them casting stones in your direction?
Musk: It's difficult.
Pelley: Did you expect them to cheer you on?
Musk: Certainly hoping they would.
Pelley: What are you trying to prove to them?
Musk: What I'm trying to do is, is to make a significant difference in space flight. And help make space flight accessible to almost anyone. And I would hope for as much support in that direction as we -- as we can receive.
Musk's Dragon capsule is schedule to dock with the space station on Friday.
