Toyota sez fuel cells are the powerplants for cars of the future, not batteries. If so Musk is toast. I'll be watching this one (eating popcorn).

SpaceX launches CR7 to the ISS today! (hopefully)

CR sez the current Tesla car is the equal of top of the line MB and BMW...

Yeah, I just heard that on the news and thought about Bronsin's post above. I think they said this was the 3rd time since SpaceX got the contract to deliver supplies to the Space Station ?

This was Mission 7 to the ISS. HArd to explain how they could have 6 successes and then something like this went wrong.

SpaceX is saying the 1st stage was nominal and the problem was in the 2nd stage. But if the 1st stage was nominal it should have soft landed on a platform in the Atlantic. It blew up or went asymetrical right about MECO which is main engine cutoff for the 1st stage. Altitude ~40 miles.

I saw something about fuel sloshing around in the fuel tanks for the 2nd stage. When MECO happens the fuel can rush to the front of the tank, (deceleration) and thuis air sucks into the engine. Which isnt good because the 200 below 0 fuel (oxygen) is routed around the engine to cool it. If the engine sees air no cooling and kaboom.

This happened to Flacon 1 years ago and supposedly was fixed.

Today SpaceX landed the first stage of an orbitial rocket back on earth at Cape Kennedy, a huge historic first. Watching all the young faces at their headquarters who watched the event was seeing the baton passed from one generation to another in The Space Age.
