But, what if Starlink 6-42 is skipped over again, and this notice is for Starlink 6-45?

Starlink 6-42?

NGA Rocket Launching for March 21 already, so I assume it's [SpX-30].

Starlink 6-45 could launch from either Kennedy LC-39A or Canaveral SLC-40 (after SpX-30).  LC-39A is more likely, as SLC-40 is currently assigned the Eutelsat 36D launch after SpX-30 and to Bandwagon-1 immediately after Eutelsat 36D.

Starlink 6-45 could land aboard either Florida ASDS.  Launch is NET late March.

Edit/add:
Could this mean that this launch (and further Florida Starlink launches) are postponed until after Bandwagon-1?

This is for Starlink 6-46 according to this NOTAM:

The NGA notice starts on March 24 and the NOTAM on March 25. Could they be for two different launches, one from SLC-40 and one from LC-39A? It would be a three-day turnaround on both pads. 😲

May be Starlink 6-45?

[Ken the Bin]

May be Starlink 6-45?

I originally posted it here. My post here was split off and used to start the 6-46 topic. That's why the first post of the 6-46 is a hybrid of the standard header combined with my post.

Which first stage will be used for this launch?
(semi-rhetorical question)

Falcon 9 first stages are now apparently cleared for use up to twenty times for non-crewed launches, although that number is apparently more restricted for Cargo Dragon or Cygnus than these other payloads.

1064.6 and 1065.6 are the Falcon Heavy side boosters for Europa Clipper.  1072.1 and 1086.1 are assigned as the Falcon Heavy side boosters for GOES-U.

1073.14 and 1076.12 may undergo modifications to become Falcon Heavy side boosters for a future launch, but both are currently available for "single-stick" launches.

Available first stages, with UTC date of most recent recovery:
1078.8    Feb 14  Starlink 6-46
1060.19  Feb 15  Starlink 6-42
1067.18  Feb 20
1069.14  Feb 25
1076.12  Feb 29  Eutelsat 36D
1083.2    Mar 4    (save for a crewed or ISS cargo mission?)
1073.14  Mar 4
1077.12  Mar 10 (maybe)

Edit March 30: It's B1067.18.

[crandles57]

JRTI Droneship used for 6-42 on 24 March
ASOG Droneship apparently headed out for 6-46 25 March.

Will either be ready again before April? I think 29th is likely to slip at least a couple of days.

NGA Space Debris notices (the same notice for two different Navigational Areas). The time between the start of the Rocket Launching hazard period and the start of the Space Debris hazard period is longer than usual. Am I missing something?

NGA Rocket Launching notice that I think is for this launch (Starlink Group 6-45) but at this point my brain is about to explode, so I don't know. 🤯

The Space Debris notice implies a 43° orbital inclination, which is not consistent with the earlier Exuma notice. It is however consistent with your most recent NGA Rocket launching notice, and is identical to Starlink 6-43.

If everyone agrees, perhaps a mod could move the earlier Exuma posts to 7-25 or 7-28?

That doesn't agree with the NGA notice, which runs 23:00 to 02:31 UTC, a hazard period of 3 hours and 31 minutes.

The last set of Starlink launches have had a hazard period of 4 hours and 31 minutes, with the first 4 hours being the launch window.

Some of those have been 22:00 to 02:31 UTC, so maybe Ben missed that this one starts an hour later and only has a launch window of 3 hours. I had to do the math several times myself to be sure that it really had changed (including again while typing this comment).

[Ken the Bin]

A new cancel-and-replace NGA Rocket Launching notice.

The Primary Day launch window now starts two hours later, on March 31 at ~01:00, and is now only an hour long. The Backup Days still have the three-hour launch window starting at ~23:00.

~Three hours later, Falcon 9 is targeted to lift off from pad 40 in Florida, delivering 23 @Starlink satellites to low-Earth orbit

https://www.spacex.com/launches/mission/?missionId=sl-6-45

SpaceX is targeting Saturday, March 30 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 9:02 p.m. ET, with backup opportunities available until 10:00 p.m. ET. If needed, additional opportunities are also available on Sunday, March 31 starting at 7:00 p.m. ET.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the 18th flight for the first stage booster supporting this mission, which previously launched CRS-22, Crew-3, Turksat 5B, Crew-4, CRS-25, Eutelsat HOTBIRD 13G, mPOWER-A, PSN SATRIA, Telkomsat Merah Putih 2, and eight Starlink missions. (= B1067-18) Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.

31 launches in 2024 so far. To give a little perspective, we launched 31 times in the entire year of 2021 - today is day 90 of the year 🤯

In just a little over 2 years we achieved the same milestone in a quarter of the time! That is some real impressive progress right there 🙌🏽🚀

And on the 7th anniversary of our inaugural re-flight! 🥳🚀

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 49.85 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad SLC-40 turnaround time:
5 days 1 hour 48 minutes
(the previous launch from this pad was Starlink Group 6-46 on Mar 25, 2024 UTC).

FYI: median turnaround time for SLC-40 is currently 5.11 days *
* – based on the last 30 launches.

Does anyone know the times (T+xx:xx:xx) for the start and end of the deorbit burn and the propellant dump for launches like this one?  I have seen something twice from Colorado Springs in this time region but have not determined exactly which event I am seeing.

The action doesn't stop at Port Canaveral as JRTI delivers Falcon 9 B1076 from Eutelsat 36D while B1067 is simultaneously lifted off ASOG, having arrived just five hours ago following Starlink 6-45.
