SpaceX launches Falcon Heavy rocket, lands 2 side boosters simultaneously on land

In a historic first, SpaceX launched its long-awaited Falcon Heavy rocket Tuesday and landed its two side boosters on land -- a feat the Hawthorne, Calif., space company hopes will lead to increased commercial and national security missions.

The company said it was still waiting on news about the landing of its center core booster, which was set to land on a floating platform at sea.

The launch occurred at 3:45 p.m. Eastern time from Kennedy Space Center Launch Complex 39A, the same Florida launch pad where the Saturn V rocket lifted off to take astronauts to the moon. The launch was delayed several times Tuesday to wait out high upper-atmosphere winds.

After liftoff, SpaceX attempted to land all three of Falcon Heavy's boosters back on the Earth -- two on land and one on a floating platform at sea. SpaceX Chief Executive Elon Musk has described the attempt as "synchronized aerial ballet." Around 8 minutes after liftoff, the two side boosters landed simultaneously on land.

The test payload for this demonstration mission is Musk's midnight cherry Tesla Roadster, which will be launched toward Mars.

But it will take a difficult road to get there. On a conference call with reporters Monday afternoon, Musk said the car -- along with a dummy named Starman who is shown on Musk's Instagram sitting in the driver's seat while wearing a spacesuit -- will do a "grand tour" through the Van Allen belts, an area of high radiation that surrounds the Earth, as part of a six-hour coast in deep space that is intended to demonstrate to the U.S. Air Force that Falcon Heavy can meet specific orbit insertion requirements.

If the car survives that environment, then it will continue on to an elliptical orbit that at times will come close to Mars, with an "extremely tiny" chance it will actually hit the Red Planet, though Musk said, "I wouldn't hold your breath."

Falcon Heavy will be the most powerful U.S. rocket since the Saturn V.

First announced to the public in 2011, Falcon Heavy is expected to generate 5.1 million pounds of thrust at liftoff and will be capable of carrying more than 140,000 pounds to low-Earth orbit.

With its large payload capacity, the Falcon Heavy is expected to help SpaceX win contracts that require more capability than its workhorse Falcon 9 rocket.
