I think I have proof that B1061 will be used for this mission. How exactly? By examining the soot markings from the previous mission.

Here are some past pictures of B1061 before IXPE and the recent dual Falcon 9 photo SpaceX posted on Twitter.

Waiting for a new launch time for this mission due to the cancellation of the CSG-2 launch.

Hold was at T-33 seconds due to ship in the range. Will be trying again tomorrow.

I see the thread title was updated to a new launch date and time.

Is that in any way confirmed, or is it just someone's assumption based on the CSG-2 scrub?

A Shortfall of Gravitas droneship is outbound for the Starlink mission NET Jan 29 at 3pm ET.

Very busy month for ASOG whilst JRTI is out of service for work after B1069 shenanigans.

What tug will be used?

It's my assumption based on CSG-2 being tomorrow.

At the end of the CSG-2 SpaceX Mission Control Audio YouTube stream, they said  "This will be our final attempt ahead of NROL 87 launch." That sounds like the Starlink launch will be after NROL 87, currently scheduled for Wednesday 2 February. Go to 59:20 in the video below.

It could also be "our final attemp (of this launch) ahead of NROL-87".

Also, for what is worth, Jami Higginbotham replied to someone saying that the three launches are back-to-back. So 31, 1 and 2.

I wondered why you removed my calculated times (the first pair of which matched what Galactic Penguin SST posted from SFN).  So I just went ahead and deleted the comment entirely (which then broke vaporcobra's link in his article, sorry Eric).

My calculated times:
February 1 at 18:56 and 22:13 UTC.
February 2 at 18:34 and 21:51 UTC.

The other part of the message was the two Space Debris notices, because you accidentally posted the Rocket Launching notice three times in your comment (you must have been tired then also), which you later removed the two extra.

The CSG-2 launch was successful.  Let's see 👀 if there's mention of this launch in the SpaceX webcast.

No, no mention at the webcast close of either upcoming launch.

 🤔
Edit to make my thought clear: Makes one think this launch is delayed until after NROL-87.

According to TFRs the Starlink launch is Wednesday but that kind of doesn’t seem right

NROL-87 likely has taken priority across all ranges for SpaceX.

I guess that but it’s on the same day around 2 hours before NROL 87 unless it takes the backup window

If there is an explanation of a (unconfirmed) delay of Starlink 4-7 until NET February 3, I'll be interested to hear it.

SpaceX launches within less than 24 hours of one another is now supposed to be within standard operating procedures?

I wonder if there are additional person-hours (man-hours) required for the actual launch day of a national security launch?  (Or HSF and/or crewed launch?)

And, it's just easier to slightly delay the Starlink launch because it's for the internal customer?

Or, did the five attempts to launch CSG-2 eat into labor costs?  Ending in the same result?

(Direct labor costs for wage employees, especially in terms of overtime.  For salaried employees, indirect costs.)
