Though fully hoping for the launch to be today, we all know full well there’s also a high likelihood of a scrub. There’s a lot riding on this launch, and I mean beyond SpaceX - a lot of folks have converged to watch this historic event and not everyone has the luxury of extending their stay to accommodate a scrub. So... what’s the likelihood of this happening?

Quote from: deruch on 02/06/2018 02:27 pmExtended coasting allows the upper stage to circularize the orbit at apogee. So, instead of delivering to a transfer orbit where the payload has to finish raising the orbit and circularizing, the upper stage does it all and injects the payload into a full direct GEO or direct MEO (Semi-Sychronous orbit).The different EELV reference orbits can be found HEREThat makes sense, thanks. So the six hours is kind of a placeholder where IF we were going to GEO, we would be using that time to move to the final position?What would a failure look like in this (FH Demo) case? Let's say we get to orbit, no problem. Start the coast phase and then BAM? Something goes wrong while coasting? I guess I am saying this (coasting) sounds easy, but I know it isn't easy.

I see venting!
So what's the duration of these proceedings - from liftoff to Trans-Mars Injection? About 13 hours?

The whole point of the static fire is to show that everything is working for the launch. There's still a good chance of a scrub, they can't control the weather or wayward boats, and they might run into something odd during the countdown. But they've already done everything except release the hold down clamps.
It's a beautiful day for a rocket launch from my favorite launchpad. #FalconHeavy
Has any mention been made of the payload mass for this mission? I presume that, in addition to the roadster, there would be some additional dummy load. - Ed Kyle
How often do they send up weather balloons? Every 15 min?
