Elon Musk says he personally called off Saturday’s launch attempt [Updated]

SpaceX

Noon ET Update: In a series of tweets on Saturday, SpaceX chief executive Elon Musk said he personally called off the launch of a Falcon 9 rocket when the system was "green" for liftoff.

"All systems go, except the movement trace of an upper stage engine steering hydraulic piston was slightly odd," he tweeted. "If this is the only issue, flight would be fine, but need to make sure that it isn't symptomatic of a more significant upstream root cause. Btw, 99% likely to be fine (closed loop TVC wd overcome error), but that 1% chance isn't worth rolling the dice. Better to wait a day."
