"The Falcons have landed" Elon Musk wrote on Twitter, inaugurating the first successful recovery of all three rocket boosters, which will be refurbished and re-fly in another Falcon Heavy mission this summer to carry a swarm of military and science satellites for the Air Force.
SpaceX made headlines early a year ago with the first-ever launch of the Falcon Heavy, and the successful return of two of its three boosters was a stunning sight. The center core landed on a SpaceX drone ship ten minutes and 20 seconds into the mission.
"What an wonderful day", a SpaceX flight commentator exclaimed. "Three for three boosters today on Falcon Heavy, what an fantastic accomplishment".
The Falcon Heavy soared from NASA's Kennedy Space Center, using the same pad that shot Apollo astronauts to the moon a half-century ago and later space shuttle crews.
All planned launch events went as planned, though high winds delayed takeoff yesterday.
The landing happened roughly eight minutes after the rocket took off into orbit and was followed by the core rocket stage landing on a SpaceX droneship in the Atlantic.
SpaceX set a company record a year ago with 21 launches for customers.
Mr Musk shared photos of the landing on Twitter, saying: "The Falcons have landed".
NASA offered swift congratulations. Then came SpaceX's successful commercial mission into space. The red Roadster - with a mannequin, dubbed Starman, likely still at the wheel - remains in a solar orbit stretching just past Mars.
The Falcon Heavy made its maiden flight on February 6, 2018.
The launch is a powerful endorsement of Falcon Heavy, which provides far more payload capacity, at far lower cost, than any competitor. The boosters for that flight may be recycled from this one.
SpaceX typically launches Falcon 9 rockets. The Falcon Heavy is essentially three of those single rockets strapped together. The company is bent on recycling all rocket parts.
