SpaceX has failed in their third attempt to vertically land a rocket booster on an unmanned ship, after their Falcon 9 spacecraft broke one of its legs in a hard landing.
The private space transport company, owned by tech billionaire Elon Musk, managed a successful landing in December, when another Falcon 9 rocket made a safe vertical landing at Cape Canaveral in Florida after delivering a payload into space.
However, it's never been able to make a landing at sea. One previous attempt failed due to the rocket coming in too fast, while the other abruptly ended when the booster tipped over due to too much horizontal movement at the time of landing.
SpaceX livestreamed the landing attempt on their website, but the video feed cut out just before the rocket touched down - however, the company confirmed on Twitter that the Falcon 9 experienced a "hard landing".
