It was close, but close doesn't cut it when you're dealing with a space rocket. For the fourth time, Space X has failed at the difficult task of landing a rocket on a platform bobbing up and down in the middle of the ocean.
Live video pictures from the barge, anchored in the middle of the Atlantic, showed the glow of the rocket exhaust as it approached, and then the picture froze. It resumed for a second before a testcard appeared, cutting the feed.
Space X CEO Elon Musk took to Twitter later to confirm the landing didn't work.
Rocket landed hard on the droneship. Didn't expect this one to work (v hot reentry), but next flight has a good chance.— Elon Musk (@elonmusk) March 5, 2016
Space X had said it didn't expect success this time around. The SES-9 communications satellite being launched called for a heavier rocket, which made the landing more complex, but the company tried anyway.
It's attempting something that's never been done, part of Elon Musk's plan to bring down the cost of rocket launches by returning the first stage to Earth for reuse.
Space X managed it on dry land in December, when a Falcon 9 returned to Cape Canaveral, but perfecting the sea landings will be vital, because many satellite orbits call for launches that will drop the rocket first stage far from land.
Here's the launch and landing:
