[zubenelgenubi]

Thread for the Starlink Group 9-1 launch.

Launch 19 June 2024, at 03:40:00 UTC (18 June 8:40 pm PDT), from Vandenberg SLC-4E, on booster 1082-5.  The first stage successfully landed aboard Of Course I Still Love You.

Payload 20 Starlink V2.0 Mini satellites, 13 of which are Direct-to-Cell, to a 53 degree inclination orbit on a southeastern trajectory.  Initial orbit 286 x 295 km.

Assuming neither Starlink 8-3 nor 7-19 are the next Vandenberg Falcon 9 launch after Starlink 8-8, then Starlink 8-9 would be that launch.

The next Vandenberg Falcon 9 launch should be NET mid June.

Well, surprise surprise...the next West Coast Starlink launch after 8-8 has shown up, but...it's named Starlink Group 9-1 in the NOTAM filings:

NGA Space Debris notice that is effectively a Rocket Launching notice.

Maps from the NGA notices. ASDS 642km downrange, in an area identical to 8-7 and 8-8.

[zubenelgenubi]

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:
1075.11   Mar 19
1082.5     May 10
1063.19   May 14
1071.17   May 22 (maybe)

I am interested in what has delayed the use of B1075.11.

Edit June 17: It's B1082.5, skipping over B1075.11 again.

Very good opportunity for Southwestern U.S. launch visibility if it launches on its first opportunity.

Good heads up.   

For the Los Angeles area here are the sun events for 18 June 2024:

Sunset:  8:07 PM PDT
Civil twilight:  8:37 PM PDT
Nautical twilight:  9:13 PM PDT
Astronomical twilight:  9:52 PM PDT

As a rough starting point, a launch at civil twilight may allow the ground observer to have adequately dark skies to see the plume.  It would be much better (darker sky on the ground) as the launch gets later. At some point, the second stage would no longer be sunlit.  That time is unknown to me but let us assume about 9:35 PM PDT.

Here is a positive.  For a given launch time that has the second stage in sunlight, the further east you go the darker the skies are on the ground, which would make a better visual experience.

To illustrate that, here are the sun events for Artesia, NM where the launch jellyfish has been seen:

Sunset:   8:08 PM MDT
Civil twilight:  8:37 PM MDT
Nautical twilight:  9:12 PM MDT
Astronomical twilight:  9:50 PM MDT

An 8:00 PM PDT launch is 9:00 PM MDT in Artesia which is almost nautical twilight.  Much better viewing conditions (darker sky) in this more eastern area. 

I use https://www.sunrisesunset.com/ to determine sun events (sunset/twilight) for various locations.  Use the "Search USA" link on the left to input your location and select months and year.  Then after it creates a calendar go back to the bottom left and select "Modify Settings" and scroll down to choose whichever twilight settings you want and again scroll down and select "Make Calendar."

Booster B1082-5

SpaceX is targeting Tuesday, June 18 for a Falcon 9 launch of 20 Starlink satellites, including 13 with Direct to Cell capabilities, to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Station in California. Liftoff is targeted for 8:00 p.m. PT, with backup opportunities available until 12:00 a.m. PT on Wednesday, June 19. If needed, additional opportunities are also available on Thursday, June 19 starting at 8:00 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 fifth flight for the first stage booster supporting this mission, which previously launched USSF-62, and three Starlink missions. 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.

Group 7 launched to 53 degree inclination from Vandenberg = 22 V2.0Mini's
Group 9 launched to 53 degree inclination from Vandenberg = 20 Starlinks.

[Steven Pietrobon]

Group 7 launched to 53 degree inclination from Vandenberg = 22 V2.0Mini's
Group 9 launched to 53 degree inclination from Vandenberg = 20 Starlinks.

The reduction by two satellites is due to the 13 direct-to-cell Starlinks (unofficial name v2d) being carried, which are a little heavier than the standard mini's (unofficial name v2m). 24 v2m's were launched with 17,500 kg payload [1]. That gives a v2m mass of 729 kg. Solving 22*v2m = 7*v2m+13*v2d, gives a v2d mass of (22-7)*v2m/13 = 841 kg.

It is interesting that Dr Kelso was only given data for one launch time yet one source listed the launch window as four hours long and another post shows a possible four hour and 31 minutes launch window.

The four hour launch window is from the SpaceX website:  "Liftoff is targeted for 8:00 p.m. PT, with backup opportunities available until 12:00 a.m. PT on Wednesday, June 19."

Falcon 9 delivers 20 @Starlink  satellites to orbit from California

[shiro]

Some reusability stats for this launch (Starlink Group 9-1):

Booster B1082.5 turnaround time:
39 days 23 hours 10 minutes
(its previous mission was Starlink Group 8-2 on May 10, 2024 UTC).

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 34.78 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad SLC-4E turnaround time:
10 days 14 hours 42 minutes
(the previous launch from this pad was Starlink Group 8-8 on Jun 8, 2024 UTC).

FYI: median turnaround time for SLC-4E is currently 9.63 days *
* – based on the last 30 launches.

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

Too cloudy in Albuquerque to see it tonight.   Your video is great info that it can be darker skies and not just dusk skies to see it as long as the launcher is sun-illuminated.   The upper stage engine does not provide enough illumination to be seen if it is totally dark for both observation site and launcher.

Perhaps, this helps explain the continued delay of launch of Group 8-9 from Florida?

Starlink 32119, which failed at launch on Jun 19, reentered over the Lake Baikal region at 2338 UTC Jul 7.
Five more failed satellites from the Group 9-1 batch will reenter in the next week or so.
The S-band DTC satellites (magenta) from Group 9-1 have all raised orbit to 326 or 340 km. One of the Ku-band sats is working ok (blue). The failed Ku-band sats (red) are now below 250 km.

Given 20 S/C were launched, and 13 were direct-to-cell units, this means 6 out of 7 v2 Mini "classic" Starlinks failed right at launch, with one of them having already reentered and the other 5 to follow suit. Interestingly, Group 9-2 shows nothing like this sort of stillbirth failure rate.
