Astronauts prepare for the first manned orbital mission in nearly a decade: "We're go for launch" - CBS News

For SpaceX and its Falcon 9 rocket, there's a 60% chance the weather on the launch pad will cooperate for a moment in space history.

"I've gotta believe that's a help," said CBS News correspondent Mark Strassmann.

CBS News spoke with SpaceX founder Elon Musk and NASA Administrator Jim Bridenstine.

Musk told CBS News that early on, he gave his fledgling SpaceX company less than a 1% chance of succeeding — and now, it's about to make history.

But Musk's goal — everyone's goal — is to launch them safely.
