At 8:29 PM EST, SpaceX’s Falcon 9 rocket blasted away from Cape Canaveral Air Force Station in Florida. Only minutes later it would make history.

For the first time—after successfully completing its commercial mission to deliver 11 satellites into orbit—the rocket returned to earth and and landed intact.

The event was broadcast live online and as the landing was confirmed cheers and chanting (USA! USA!) erupted from employees at SpaceX headquarters in California—and all across the Internet.

The successful landing could have a huge impact on future space travel. Until now, a rocket booster could only be used once—after lift-off, they often end up exploding or in the ocean. But now SpaceX founder Elon Musk has found a potential way to reuse rockets and cut down on the costs that limit space exploration.

SpaceX founder Elon Musk has been open about his plans to get to humans on Mars and this landing puts him one step closer. As the Washington Post reports:

As Musk said during a forum last year, there are “no runways on Mars,” meaning rockets would have to land using the thrust in their engines. “You really have to get good at propulsive landing if you want to go somewhere other than earth,” he said.

The company has tried to land rockets twice before but both times ended badly. Aiming for a floating landing pad in the ocean, one attempt resulted in an explosion and the other just didn’t quite make it.

This time, SpaceX made some important adjustments, lowering the temperature of the both liquid oxygen and the kerosene fuel.

It also probably helped that the landing was spot-on. Musk called the moment revolutionary, saying that it landed “dead center on the landing pad.”
