Saturday’s attempted launch of SpaceX’s Falcon 9 launch vehicle and Dragon capsule looked like it was going to go off without a hitch. Until one second remained in the countdown.
Launch aborted: slightly high combustion chamber pressure on engine 5. Will adjust limits for countdown in a few days.

Engineers have spent the last few days looking over the number five Merlin 1C engine and have determined the Falcon 9 can be cleared for another launch attempt tomorrow morning, only a few days after the latest scrub.
With any luck, at 3:44AM EDT the mission can resume and we’ll find out if we’re one big step closer towards a new crew transport vehicle.
