Yep - these launches are instantaneous time windows, so no way to reset until at least tomorrow. They had a launch a couple years ago that it seems like did this 2-3 times in a row while a sensor of some sort kept tripping. Sucks, but it's good that the computer can sense possible issues before it becomes a problem in the air.

That was interesting how the called liftoff when it hadn't. That's a first.

What is “out of family data”?

Kinda sorta sounds like another way of saying they were hacked :shrug:

My understanding is that they have a bunch of sensors (a "family"), and when one of them starts reporting something that the others don't, it's considered to be "out of family." One possibility is that one of the sensors that measure engine thrust was providing a reading that was out of line for the rest, so the system shuts down in case there's an engine problem.

Got out the duct tape and zip ties, I guess.

I'd bet it's just a sensor issue.

Yeah, loose one. ;)

I've been wondering about the Demo2 flight. They are going to the ISS, right?

Yeah, and extending it into a long-duration mission apparently.

I missed this morning's launch, but apparently it was eventful. One engine failed on ascent - first time since the first Falcon 9 launch (and that was technically a M1C instead of a M1D). Regardless, it's a resilient vehicle and got the satellites into orbit fine. Landing wasn't possible, though.

You can see it briefly at T+2:21.

Wonder if that will impact Demo-2 launch time.
