    Yay!  Space exploration go!  Boo! Thruster issue.

    I am so utterly psyched by this!

    watch out, Elon Musk might get upset if you call it a thruster problem.

    Reportedly they tried liftoff during suboptimal conditions.

    Probably ice from water vapor in the oxidizer line.  I worked at Pratt & Whitney back in the day and they had an upper stage failure that they traced to water vapor.  When you chill the engines down to liquid oxygen temperatures, the water vapor freezes and blocks the fuel or oxidizer lines.  When P&W built the rockets they would dry them in an oven and then weld them up in a container to keep them dry, but even a pin-hole leak was enough to cause the failure if they were left long enough.

    Some people are so quick to criticize on small oops. let them try it and show how perfect they are themselves. They should think and learn about how engineering marvels are continuous string of fine small details. Surely different than sitting on couch sipping beers and ridicule other people’s sleepless achievement. Hooray, Elon Musk…. I have a lot of respect for the young pioneer who struggles carry on not much left American technology.
