Launch moved forward from November to August.
What about Starlink Group 4-23 and Group 4-24?
Perhaps coming later down the line. They haven't been doing these missions in order for a while.

Starlink 4-23 is now listed on NextSpaceFlight for [NET] November 2022 [June 1]

Starlink 4-24 is now listed on NextSpaceFlight for [NET] December 2022 [June 1]

Starlink 4-23 NextSpaceFlight has been updated in the meantime.

Launch moved forward from November to August.
I still see November on the website.



Looking ahead, what first stage will Starlink 4-23 launch on?

Rotating forward the boosters available in Florida, by oldest available after previous recovery, but not already assigned, gives us: 1052.6 (May 18), 1060.14 (June 17), 1061.10 (June 19), 1073.3 (June 29), 1058.14 (July 7) and 1067.6 (July 15), and possibly 1051.14 (July 17) and 1062.9 (July 24).

KPLO/Danuri, launching on August 2 UTC, is said will use a booster already recovered 5 times. 1067.6, if recovered successfully on July 15, likely will not be ready.  That would make 1052.6 the first stage for Danuri.

Deducing from the "last use" rotation, 1060.14 will launch Starlink 4-27.

Following this rotation, 1061.10 will launch Starlink 4-23.

None of the available first stages would require a Static Fire.

Edited July 25

First stage is 1067.6--no need for a Static Fire.

1052.6 : KPLO
1061.10 : Starlink 3-3, after transported to Vandenberg
1073.3 : Starlink 4-26
1062.9 : Starlink 4-27
1069.2 : Starlink 4-20

Edited August 3

Edit August 25: B1069.2 Static Fire this morning EDT.  It was moved forward to Starlink 4-23.

Ben Cooper indicates that the pad has been switched to SLC-40. Is this because of possible conflicts with nearby LC-39B with SLS?

Map from the NGA notice. ASDS 655km downrange.

Edit: added the space debris map, north-east of French Polynesia, but suspect that from the horizontal line just north of the equator, it is incomplete.

It only delivered B1062 to port 9 hours ago, but ASOG has been turned around and is heading downrange for Starlink 4-23.

Here are NGA Space Debris notices (the same notice for two different navigational areas).  I assume that they are for this launch even though there is no Space Debris hazard warning period for the last Rocket Launching hazard warning period.

Hearing of potential static fire test for this mission tomorrow. T-0 would be in the morning EDT. We'll see if it happens.

Apparently SpaceX pulled out a last minute change of booster. This is now B1069-2, explains why they're doing the static fire. 9 new engines for this booster.
