Jeepers. The intensity of the mission numbering debate above could come straight out of an episode of Big Bang Theory😀.

Droneship support ship GO Quest has departed from the Port of Morehead City towards the Starlink LZ.

A great sign that SpaceX is still working towards Falcon 9 liftoff on Wednesday.

I'm pretty sure that on their website SpaceX will call these missions "eighteenth Starlink mission" and "nineteenth Starlink mission" in whichever order they fly. And we'll see what they send in the emails to the space tracking community (e.g. T.S. Kelso called the previous mission Starlink-18 on CelesTrak and SpaceX had specifically told them to use this very numbering in some previous emails).

It’s possible that SpaceX will refer to this as the 19th Starlink mission, counting the 10 from Transporter-1. We will get official word soon.

There is not the slightest chance in the world that Space will add one to its count because of Transporter-1!

50% GO for tomorrow, +90% GO on backup day. Booster recovery risk is still high, vs moderate/low on backup day.

According to Ben Cooper, this launch is now planned for "February 4 at 5:36am EST".

The next (or maybe previous :) ) Starlink launch is now planned for "February 4 or 5 earliest at 1:19am or ~12:58am EST".

Can they launch two missions within a little more than 4 hours according to what we know? I doubt it.
GO for launch, GO for age of reflight

Yes, according to previous statements from the Eastern Range. AFTS makes it possible.

Just wanted to note that this is the seventh time that the launch date has changed since originally announced.

Wonder if that’s a record? 😂

BTW how do we know the "L17" & "L18" designators are assigned to specific rockets/satellites and not sequential?

Those are the mission names they provide to the range.  They are on all of the planning documents (weather forecasts, hazard areas).

Someone forgot to tell 45th media team ...

The 45th Space Wing has approved the launch of two SpaceX Falcon 9 missions carrying hundreds of Starlink satellites.  Working extremely close with our FAA, USN, and international partners, Starlink L-17 and Starlink L-18 are approved to launch at 0536L and 0119L, respectively.

This is the first time since 11 November 1966 that two launches will lift off from the Eastern Range on the same day. Those previous missions were Gemini 12 and Atlas Agena which lifted off 99 minutes apart from each other. The two Falcons will lift off less than 5 hours apart.
