First launch attempt was held at T-1:30 due to a range safety issue. Not scrubbed yet. They've recycled the countdown clock to T-10:42, but still holding.

Abort, just after engine start.

Elon Musk: "Launch aborted on low thrust alarm. Rising oxygen temps due to hold for boat and helium bubble triggered alarm."

Teething issues with the superchilled lox probably.

No, they had to hold for the range violation during which time it warmed up. Not a SpaceX problem.

I'm down at the Space Coast right now, and I don't get what happened here. How could a ship violate the range? SpaceX is obviously paying a lot of money to launch from the cape, you would think these types of issues would be addressed.

Ships are allowed to sail near the range. One of them sailed into it. I was guessing that it was Jeff Bezos' yacht, but probably not.
