We're past T-3:40 where the previous attempt failed. Edit: Flight computer has aborted after engine fireup.

They say that after every failure. It's part of the abort sequence that they confirm - not necessarily the cause of the abort.

Sure, but in this case it was the actual flight computer that aborted the launch. No human had a part in it :)

Thanks for submitting this now rather than 15 minutes from now! Moments like these are historic, and it's wonderful to experience this in realtime rather than watching a replay. T minus 10min. Go SpaceX! EDIT: It's impressive they were able to abort safely after ignition. That's historically rare, isn't it?

Aborting after ignition is only possible with liquid engines. The F9 in particular is designed to light and stabilize all nine engines before removing the restraints holding the rocket down - this gives them very robust abort capabilities. And since the engines are designed for multiple lights, they can even retry it without needing refurbishment.

I'm not sure how rare it is with liquid fueled rockets, but I know it's not even possible on solid fueled rockets (like the Shuttle's two boosters).

Just said that they're putting a bit more fuel on in the hopes of trying again if the engineers can figure out what went wrong, their window is about an hour.

Also said that if not today, they have more or less the same window tomorrow

EDIT: someone just said starting the clock momentarily ... looks like they might be going again

Looks like they'll make a second attempt. He just said "resetting to t-13 minutes"

The operations team are getting ready in case the engineering team give the green light

Musk seems to think they're going forward.
