SpaceX cancels Falcon rocket launch seconds before liftoff

Countdown at Kennedy Space Center was halted with just 13 seconds remaining over a 'slightly odd' thrust control problem, delaying launch until Sunday

SpaceX scrubbed a planned launch on Saturday from Kennedy Space Center, citing a "slightly odd" thrust control problem and delaying the return to service for a historic launchpad at the Florida spaceport.

"All systems go, except the movement trace of an upper stage engine steering hydraulic piston was slightly odd," CEO Elon Musk said on Twitter. "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."
