Cross-post regarding first Starlink Group 8 launch:

ASDS North  29  52  50   West  116  45  3
[NET Sep 25]

ASDS same coordinates as Group 7 (non dogleg).  Indicates probable 53 degree inclination?
Perhaps Group 8 indicates a satellite variant change like Group 5 (V1.5) and Group 6 (v2.0Mini) did.
Perhaps the first production V2.0 Mini F9-3 variants? 
In an September 1 FCC Filing.  SpaceX indicated.

"Dear Ms. Dortch:
SpaceX is poised to bring the massive benefits of ubiquitous mobile coverage to millions of American consumers—and billions around the world—through supplemental coverage from space.1 SpaceX met with Commission staff on August 30, 2023 to urge the Commission to expeditiously grant its modification application to support upcoming launches of its direct-to-cellular capabilities.2 As SpaceX has shown at length in these proceedings, this barrier-breaking technology will serve the public interest and advance the Commission’s ambitious space agenda without causing harmful interference to other in-band, out-of-band, or cross-border users.
Sincerely,
/s/ Jameson Dempsey"

Starlink 8-1 now moved from NET Oct 2023 to Q4.
This perhaps solidifies the concept that Group 8 is a "Satellite Varient (F9-3)" change.

This likely pertains to Starlink 8-1.

More on SpaceX D2D "Scope of Grant"

The most important.  "Authority to Launch"
This Grant authorizes SpaceX for the Launch of  "Modified" satellites (up to 7,500 Gen. 2)  into the three authorized Gen. 2 orbital parameters and allows "limited on-orbit check out in the PCS G Block of the satellite buss and antenna deployment for a period of 10 days or less. This authority does not permit LEOP operations. Only the initial 10 day check out period on orbit.

This authorization was the first necessary step in the process.  You can not authorize the  "launch of satellites" on a STA. So this is the purpose of this License Grant.  SpaceX will need to perform LEOP operations shortly after the payloads are past the initial checkout period. 

That is where the new STA SpaceX applied for today 12/01 comes into play.

SES-STA-INTR2023-06753

"SpaceX will conduct its payload testing activities during the launch and early orbit phase (“LEOP”) of the satellites’ mission. During the critical check-out phase, which will begin within hours of launch at an altitude between 290 km and 350 km—depending on the particulars of the specific launch—and will continue for several weeks for each satellite, SpaceX will test the functionality of each direct-to-cellular payload and its network capabilities to ensure that they are operating as intended. Permitting this initial, internal LEOP check-out testing over several weeks (or longer as necessary) for each satellite is critical to assess and address issues as they arise."

Then eventually they will transition to the previously filed STA on October 2nd. for wide-spread testing with TMobile.
SAT-STA-20231002-00240

"Direct-to-cell STA to launch and test its non-geostationary orbit NGSO second generation Gen2 satellites with direct-to-cellular communications payloads to connect unmodified cellular phones directly to SpaceX Gen2 satellites"

Every D2D operator that will provide service to the US will require authority to launch from the FCC.

https://twitter.com/FREESPEECH1017/status/1730971108495823025

Quote
Correct.  10 days, then the STA will be approved fo[r] LEOP testing, 30 days, renewable.  The take away is, you can't launch on a STA.  Because you can not easily "unlaunch them" if the STA is not renewed. Watch for a series of filings next week for D2D missions @FCC. I suspect that the 800 satellite number will include at least 1 Starship launch.

Only 1 launch slot available on or around March 22nd.

SpaceX applied for 7-18 - 7-23 from Vandenberg today.  Looks like Group 8 flights will launch from Eastern Range.

That's quite a quick assumption given there's still 8-2 and 8-3. Also 8-1 hasn't been filled for the Cape and they can just renew the existing application for another 6 months.

Starlink 7-17 successfully launched earlier today [Mar 11] UTC.  Is [Starlink 7-16] the next Vandenberg Falcon 9 launch, or Starlink 8-1?

Edit: Starlink 7-16 is next.

Will USSF-62 launch before or after Starlink 8-1?

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

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

Available first stages, with UTC date of most recent recovery:
1082.3     Feb 15  (Save for USSF-62 or WorldView Legion Flight 1?)
1061.20   Feb 23
1081.6     Mar 4
1063.18   Mar 11

Edit April 5 UTC: It's B1081.6, skipping over B1082.3 and B1061.20.

Edit April 10: USSF-62 will launch on B1082.3.

Due to unfavorable weather, we are standing down from tonight's Falcon 9 launch of @Starlink from California. Vehicle and payload remain healthy. Teams continue to keep an eye on the weather as they work toward the next best opportunity for liftoff – we will announce a new launch date once confirmed on the Range.

2. CANCEL THIS MSG 120756Z APR 24.

Remember that west coast operations are not like East coast operations.
OCISLY shuttles between the port of Long Beach to the landing area,
then back to Long Beach with the landed rocket.
Then a barge can carry multiple Falcon 1st stages to Vandenberg.

I think of the trip from Long Beach to the landing area as about 2 days.
Hence OCISLY can support 2 landings 4 days apart.
SLC4E takes longer to turn round than LC40.
Plus the additional barge voyage and fewer rockets in the refurbishment pool
lead to a touch longer than 4 days cycle time as the norm.

I'm hand waving a bit since I've not kept detailed records of the above.
However I have followed most Falcon 9 launches in detail - hence the above is my impression of the answer to your question.

Hope this helps

If SpaceX pulls off the Vandenberg launch tomorrow night, that'll be the fastest turnaround time at SLC-4E. The current record is 5 days, 5 hours, 22 minutes, and 20 seconds, new record could be as short as 3 days, 23 hours, and 55 minutes.

https://www.spacex.com/launches/mission/?missionId=sl-8-1

Quote from: SpaceX
SpaceX is targeting Friday, April 5 for a Falcon 9 launch of 21 Starlink satellites, including six with Direct to Cell capabilities, to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. Liftoff is targeted for 7:31 p.m. PT, with backup opportunities available until 11:25 p.m. PT. If needed, additional opportunities are also available on Saturday, April 6 starting at 7:25 p.m. PT.

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

This is the sixth flight for the first stage booster supporting this mission, which previously launched Crew-7, CRS-29, PACE, Transporter-10, and one Starlink mission. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.

That was the same number that was launched on Starlink Group 7-9 on 3 January 2024. Perhaps they are still in the testing phase.

For West Coast and South Western US Viewers

Quote
A Falcon 9 rocket is scheduled for launch from Vandenberg SFB, Calif. this evening (April 6). The vehicle is slated to leave the south base between 7:25 and 11:17 p.m. PDT and carry 21 Starlink satellites into orbit.

If the vehicle lifts off early in the launch window, a large portion of the southwestern U.S. and northwest Mexico could be treated to an interesting display as the rocket's exhaust is illuminated by the Sun at high altitude while suspended in a dusk or dark sky.

Following stage 1/stage 2 separation, three white, star-like objects may appear to follow the rocket. The two objects closest to the rocket are the jettisoned halves of the protective payload shroud (nose cone). The object farthest behind the Falcon 9 is the first stage.

Observers with an unobstructed horizon may briefly see the bright orange flame from the first stage as it prepares to land on a drone ship downrange.

If the Falcon 9 is launched later, the event could still be visible to the unaided eye for hundreds of miles, but the exhaust plume will be much less pronounced.

Although this event could be visible to the unaided eye over a wide area, tripod-mounted binoculars or a telescope may provide a surreal view.

And another booster back home. Some fire out of the aft is usual after touchdown, but it seemed like a lot that time - before they cut off. Could have been the lighting.

The recent shells bear no relation to the ones specified in the FCC filings, but it seems that this launch is heading for 53 deg like Group 7. Unclear what their operational altitude will be.

I saw the launch "comet" seen from Albuquerque tonight.  I did not look for some of the first stage stuff so I don't know how much of that would be visible above the horizon.

Now that I know its doable, I might have to go to a place with a more unobstructed view for a future launch.

And it looks like Stage 2 has a Mission Extension Kit installed, hence the gray band on the bottom half.
Wonder why. 

Also wondering what 1081 will look like upon return.

What does B1081 have to do with the MEK? The MEK is installed on the RP-1 tank of Stage 2, which I'm not sure if it did something else after payload separation.

The next extra-long Falcon 9 mission is coming soon, Galileo.
Maybe SpaceX wanted to test something at this launch, if a “Mission Extension Kit” was on board.
This kit probably includes further extensions that cannot be seen from the outside.

IIRC they've also flown Mission Extension Kits before just because that was the next available second stage they had

We saw this from a Hacienda near Chihuahua in Mexico Our whole eclipse chasing tour now knows a whole lot more about SpaceX

Apologies for the poor quality as this was taken from inside our moving bus.

I just stumbled on another videographer that takes videos of launches.  He incorporated SpaceX and Narration.  His location (North of San Diego) provides an excellent view of the booster entry burn.  Since he lives a long way downrange (370km/230 miles) it took a minute before the LV was visible.  If he continues to provide coverage I will have a third contributor for VSFB launches.

Caught the 2nd Starlink launch from Vandenberg SFS in a week. Higher vantage point this time (240m) and slightly shorter distance (370 km).

Stills, nearly a minute of flight time before the rocket was visible, passing 7000m altitude.

The 20-second gap in the middle of the sequence due to loss of focus and stopping/restarting recording to switch to manual.

Tracked 1st stage return entry burn in the final sequence of recording.

The Inset video is SpaceX's video feed. Audio commentary is SpaceFlightNow narrator.

Nothing.  Two separate thoughts.  I'm wondering about 1081 because when we last saw it after landing it was on fire and SpaceX abruptly cut its feed.

Ed I saw that and wonder about that too.  My photographer contact who records all the boosters coming into the port has left so I won't be able to verify how it looks.

Looks like OCISLY is off San Diego now, coming straight in toward Long Beach, so not behaving like there are any problems.
[EDIT] Looks like she arrived Long Beach later during the day on April 8.

 - Ed Kyle

the actual turnaround time also depends on the barge travel and departure date from LB to VSFB.  Since the wait for two cores to send a barge, B1081 could be waiting until the next flight, or the barge is waiting for this core to shove off.

Realsnouns,
Wanted to ask if you could add to your task the following:

Is it possible for you to identify the barge that hauls the cores and farings from LB to VSFB and do tracking for us?

We appreciate your effort with the tracking you do.

Best

Some reusability stats for this launch (Starlink Group 8-1):

Booster B1081.6 turnaround time:
33 days 4 hours 20 minutes
(its previous mission was Transporter-10 on Mar 4, 2024 UTC).

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-4E turnaround time:
4 days 23 hours 55 minutes
(the previous launch from this pad was Starlink Group 7-18 on Apr 2, 2024 UTC).

It's the fastest turnaround ever for SLC-4E launchpad.
The previous record was 5 days 5 hours 22 minutes between Starlink Group 7-11 and Starlink Group 7-12 launches in January, 2024.

FYI: median turnaround time for SLC-4E is currently 10.97 days *
* – based on the last 30 launches.

The same type of stats for previous SpaceX launches may be found on this spreadsheet online.
