Elon Musk said on a conference call with reporters that the launch "seems to have gone as well as one could have hoped with the exception of center core. The center core obviously didn't land on the drone ship" and he said that "we're looking at the issue." Musk says that the core ran out of propellant, which kept the core from being able to slow down as much as it needed for landing. Because of that, the core apparently hit the water at 300MPH, and it was about 100 meters from the ship. "It was enough to take out two thrusters and shower the deck with shrapnel," Musk said. That should be worth seeing on video: "We have the video," Musk confirmed, "it sounds like some pretty fun footage... if the cameras didn't get blown up as well."
For the first time, in a long time, I have hope of watching a moon landing as an adult.
