The Jason-3 ocean monitoring satellite successfully reached orbit today following a late morning launch from Vandenberg Air Force Base in California. But SpaceX's third attempt to land the first stage of its Falcon 9 rocket on a drone ship came up short. SpaceX CEO Elon Musk said one of the rocket's four deployable landing legs failed to lock in place, causing the rocket to tip over.

Bad news on the first stage arrived a few minutes later:

But the primary mission of deploying Jason-3 was a success:

SpaceX offered a commentary free version of their webcast. Here it is; spacecraft deployment comes about one hour, 38 minutes into the video:

Further analysis revealed the first stage was right on target. SpaceX appears to have mastered the accuracy portion of their drone ship landings; they just need to perfect the touchdown: 

Elon Musk tweeted the aftermath of the rocket's Rapid Unscheduled Disassembly, or RUD:

He went on to re-iterate a few details about land versus drone ship recovery scenarios:
