The middle booster, after pushing the payload into space, returned almost ten minutes later for a successful landing on SpaceX's seafaring drone ship 645km off the Florida coast.
SpaceX launched its Falcon Heavy rocket yesterday, ferrying the Arabsat-6A satellite to geosynchronous orbit in its first commercial mission.
Less than 10 minutes into the flight, the rocket's three boosters detached from the Falcon Heavy on schedule. As SpaceX explains on its website, this vehicle is the most powerful (operational) rocket now in existence.
The satellite will be deployed approximately 34 minutes after liftoff.

Peut-être que, dans le futur, il vaudrait mieux donner le mot de passe au petit pour éviter d'autres problèmes du genre. L'appareil est bloqué pour plus de 25 millions de minutes.
The version of the Falcon Heavy that will fly this week will not be exactly the same as the previous mission: The Falcon Heavy's rocket cores will be more powerful, making use of upgrades to SpaceX's smaller workhorse rocket, the Falcon 9. But everything went exceedingly well and the satellite ended up in the proper orbit. Another important distinction: All three of the Falcon Heavy boosters returned safely to Earth.
Mr Musk shared photos of the landing on Twitter, saying: "The Falcons have landed". It's nearly certainly still in orbit around the sun with a mannequin at the wheel. This telecommunications satellite will service areas of Africa, the Middle East, and Europe.
The Thursday April 11 launch marked the first flight of the 230-foot-tall (about 70 meters) rocket with the payload from a paying customer.
The satellite was constructed for the Saudi Arabian company by USA contractor Lockheed Martin.
Until SpaceX came along, boosters were discarded in the ocean after satellite launches.
