That call out was regarding Launch Complex, Youtube Technical webcast 33:31https://www.youtube.com/watch?v=7WimRhydggo?t=2010
T+14 minutes. Think I heard "No indications of fire on ASDS".
Quote from: Brian45 on 01/15/2017 02:03 pmDidn't see any comment on this so I thought I'd ask.Watching the launch yesterday I noticed the number 29 on the lower part of the rocket, just above the octoweb. Does anyone know what that number is? The 29th rocket?It is booster 1029. However this was the 30th Falcon 9 launch (F9-030). I assume the reason that the booster s/n is lower than the flight number is because they changed the s/n syntax with the introduction of Block 2.

Do you count the September explosion as a launch (attempt)?I do not. (For me the Iridium-1 flight was flight #29, 28 of those were successful.) Nor do SpaceX, ot his booster should have been at LEAST #30.
On the tech webcast shortly after s2 startup they say "mvac pu is active". Did I here that correctly? what is mvac pu?
I count it as a launch attempt, and so does SpaceX actually.
thanks for the clarification. Does that mean we'll see the "29" again on the launch pad at some future date (assuming the re-use this core)?I don't recall seeing this number label on previous launches. Was it just the camera angle?
I know this is all semantics, but F9-29 was not an actual launch attempt as I'm sure you are aware.
This is first painted number we've seen...

I would bet that stage serial numbers are 0 indexed.

PU could be a variety of things.
Propellant Utilization, presumably. Adjusts mixture ratio for more complete propellant consumption.

Can you point me to some of those pictures? I'd love to see them.
My old workhorse computer got so excited it crashed and rebooted back up with 15 seconds to launch... Just what I needed, more nail-biting...
