Video Shows SpaceX Falcon 9 Rocket Land on Droneship, Then Fall Over and Explode

The short video, which Musk posted on Instagram, shows the Falcon 9 rocket first stage touching down on the drone ship as planned, but then falling over to hit the deck and explode. Musk has said one of the four landing legs on the rocket failed to latch securely, leading to the fall. The rocket landing occured after SpaceX successfully launched the Jason-3 satellite into orbit from Vandenberg Air Force Base in California.
