SpaceX pulled off quite the feat today when it launched the Falcon Heavy rocket. What's more, it landed the two flanking boosters in perfect synchronized formation. But the fate of the core booster was unclear; now it appears that the center booster, which was supposed to land on a drone ship, was lost.

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."

Elon has stated during the post launch Press Conference (aired live by ABC https://www.youtube.com/watch?v=cygUnhAGdWc ) that the center core ran out of TEA-TEB ignition fluids. These are used to restart the Merlin 1D engines in flight. The central engine relit, but the outer two failed to reignite. The resultant loss of thrust cause the center core to hit the water at 300mph/500kph and explode. Elon reports two drone ship thrusters on OCISLY were damaged or destroyed.

TEA-TEB is a reference to triethylaluminium-triethylborane.

takyon: Instead of becoming an Earth-Mars cycler, it appears that the car has overshot its intended orbit and will reach far into the asteroid belt:

Elon Musk's Tesla Roadster, which launched on top of SpaceX's Falcon Heavy earlier today, is going farther out into the Solar System than originally planned. The car was supposed to be put on a path around the Sun that would take the vehicle out to the distance of Mars' orbit. But the rocket carrying the car seems to have overshot that trajectory and has put the Tesla in an orbit that extends out into the asteroid belt between Mars and Jupiter. [...] SpaceX CEO Musk tweeted out a map of the Roadster's final orbit after the burn, showing just how far out the car will travel. And it looks like it's going so far into the asteroid belt that it will get relatively close to the orbit of the dwarf planet Ceres.

    Well, maybe he has more fuel, and can turn around and slow his roll.

    By the way, watch this Youtube to get a sense of the sound of this rocket, and the triple sonic booms as the boosters land.

    Play this video with headphones, or at least your best ear buds. Turn it up.
