Possible final pre-ignition LOX dump occurring.
Quote from: Daniels30 on 06/15/2017 10:14 pmPossible final pre-ignition LOX dump occurring.I don't think I've ever seen a 'pre-ignition LOX dump' mentioned before, Is that really a thing?
Looking at thumbnail of Bulariasat test fire over at Spaceflight Now, I think I see the payload already mounted! Anyone else see that?
Yes I see now... I mistook a patch of sky showing through the tower structure as the dome of the fairing. Thanks and sorry to bother.
So by fairing valve, do they mean the little vents visible on the pad that pop off in flight? Or could it be the plumbing that takes care of the thrusters for fairing orientation after fairing sep?

Given that they have done complex repairs over night before. Given that launch weather is not favorable. Given that they are planning on a continued high launch cadence. Maybe they decided to not push as hard for launch as they have sometimes done?
Static Fire is June 20. Two individual launch teams, so possible to keep to the schedule, even if SpaceX launches BulgariaSat-1 the same day (based on the new back up date to the new NET 19th target).

One is at the Cape and another is at Vandenberg, would that really be an issue? Could be, depending on TDRS scheduling. Atlas VAFB launches use TDRS east, and possibly all 3 locations depending on the flight profile. Not sure about SpX.And Echostar is definitely using TDRS east.It's not just the launch window, it's how long through the plus-count TDRS is required.

If the answer to both launches is YES, then...Are there any potential TDRSS scheduling conflicts, given two same-day launches?Does Chris' statement imply that there are no such scheduling conflicts--or that the potential conflict is already worked out?Inquiring minds want to know!
So it seems that the Falcon is on the pad right now. Anyone know why?

Maybe they want to test their new fairing valve in the vertical orientation or in some more realistic pre-flight scenario?
