It's SpaceX to the rescue after NASA officials made a tough safety call to send Boeing's Starliner spaceship back to Earth without its two astronauts.

The capsule rocketed into orbit to fetch the test pilots whose Boeing spacecraft returned to Earth empty earlier this month because of safety concerns.

SpaceX launched a NASA astronaut and a Russian cosmonaut toward the ISS today (Sept. 28), on a mission unlike any other the company has flown.
