The core was one of three that made up the Falcon heavy rocket.
In an announcement that the company certainly wishes it didn't have to give, SpaceX revealed to The Verge that the Falcon Heavy center booster was swallowed up by the ocean after it landed safely on the company's drone ship. SpaceX has been making excellent progress, but just had its latest bump - having its central Falcon Heavy booster fall over in choppy seas off the coast of Florida.
And while SpaceX crew members tried to keep the booster steady during the trip home, that plan was aborted when the droneship encountered "rough sea conditions", according to the company. Unable to remain upright, the rocket tipped over and fell into the ocean. While we had hoped to bring the booster back intact, the safety of our team always takes precedence. "We do not expect future missions to be impacted" by the loss of the Arabsat booster, Gleeson said.
The Falcon Heavy's three first-stage boosters are modified versions of Falcon 9 first stages.
Musk tweeted Tuesday that a special robot created to batten down rocket boosters while they taxi to shore was not able to latch on to the Falcon Heavy core.

Japanese court extends ex-Nissan chief Ghosn's detention by 10 days
Ghosn's initial detention period was set to expire on Sunday, and had been widely expected to be extended by the maximum 10 days. Ghosn led the Japanese automaker for two decades and says he is innocent of the accusations that led to his downfall.
Musk says custom devices to secure the booster weren't ready in time for this second flight of the Falcon Heavy. Whatever it was that caused SpaceX to build two Falcon Heavy Block 5 center cores almost back to back, that foresight or luck now means that B1055's untimely demise should have little to no impact on SpaceX's launch manifest, including the imminent STP-2 mission.
SpaceX was also able to recover both fairing halves of the megarocket for the first time. Falcon Heavy, which is the most powerful operational rocket in the world, was used to put a satellite from the Saudi Arabia-based TV and radio provider Arabsat into orbit.
SpaceX tries to re-use rockets, payload fairings, boosters and other parts to try to cut down on the cost of each rocket mission.
