This means the company has successfully launched and landed a first-stage booster of a rocket like its Falcon 9 at least 260 times. The first stage of a rocket is the largest and most expensive part of it, and SpaceX has designed its Falcon 9 rocket's first stage to perform controlled descents back to landing pads or drone ships to be reused -- significantly reducing the cost of launching payloads into space.

"The design intent is that the rocket can be re-flown with zero hardware changes," Musk said in 2017, referring to the Falcon 9 first stage. The Falcon 9 rocket first launched in June 2010. "In other words, the only thing that changes is, you reload propellant."

At the time, Musk said a single Falcon 9 rocket could be reflown at least 100 times, adding: "Actually, really, we could make 1,000, but it probably isn't quite there. I'm being careful." The most number of times a single first-stage booster has flown stands at 16 times.

Still, the feat was celebrated by SpaceX fans, who joked that the rocket "seems safer than a Boeing."

That launch came just three hours after SpaceX launched a Falcon 9 rocket carrying a Eutelsat 36D geostationary telecommunications satellite, which will provide TV broadcasting and government services to customers in Africa, Europe and parts of Asia.

About three minutes into launch, Falcon 9 separated from the payload and touched down aboard the droneship Just Read the Instructions in the Atlantic Ocean at 6:01 p.m., marking the 259th reflight of a Falcon 9 rocket.
