Well he's probably pretty happy that he did because this time it didn't exactly go to plan.
What you're looking at is the Falcon 9 rocket that had previously sent the Jason 3 satellite into orbit. The plan was to place the satellite in orbit then successfully land the rocket on Space X's floating launchpad.

Don't panic though, this is far from a major disaster, in fact if anything it'll be supremely useful to the Space X team who are taking every opportunity to test their new reusable rocket system.
