The Falcon Heavy's liftoff from Launch Complex 39A at NASA's Kennedy Space Center created a spectacle, just as it did during the maiden launch.
A 2018 test already had proven the side boosters could land themselves.
The US Air Force tapped SpaceX in 2018 to launch a classified military satellite, which cost it $US130 million ($182.3 million), and in February added three more missions in a $297 million contract.More news: Disney+ Price, Release Date, & More Exciting Details Announced
And smooth it was: All three of the Falcon's rockets guided themselves home once they'd served their goal.
The rocket's side boosters landed at the SpaceX Landing Zones 1 and 2 within seconds of each other, while the center core landed on the "Of Course I Still Love You" droneship located in the Atlantic ocean, the company has confirmed.
The Arabsat-6A satellite deployed from the rocket's second-stage about 34 minutes after liftoff.
It consists of the equivalent of three Falcon 9 rockets combined, tripling its thrust. But the middle booster missed a seaborne platform it was created to land on, and instead splashed into the ocean.More news: Uber reveals finances as it gears up for IPO
"Three for three boosters today", a SpaceX webcast commentator said. As such, this marks the first commercial mission for SpaceX's powerful rocket. That mission was more of a test than anything else, with head man Elon Musk deciding to send his own Tesla as the rocket's payload. It's nearly certainly still in orbit around the sun with a mannequin at the wheel.
Since then, the U.S. military and private clients have signed contracts for Falcon Heavy launches, and NASA has raised the possibility it may use the rocket for its planned missions to the Moon.
SpaceX has several paying customers committed to flying on Falcon Heavy, including Inmarsat, Viastat and Arabsat, according to its launch manifest.
The satellite is created to provide television, internet, telephone, and secure communications to customers in the Middle East.More news: USA military also 'terrorist force'
High wind speeds far above the ground were responsible for derailing yesterday's launch, and we won't know for sure whether things are calm enough for a launch until SpaceX makes the call.
