Discussion thread for the Starlink group 4-11 launch from Vandenberg Space Force Base.

NSF Threads for Starlink Group 4-11: Discussion

Launch is February 25, 2022 at 17:12 UTC (9:12 am PST) on Falcon 9 1063.4 from SLC-4E. Booster landing anticipated on Of Course I Still Love You. Fairing recovery is expected from the water.

Payload: A batch of 50 Starlink satellites. Expected deployment orbit of approximately 306 x 316 km at 53.2 degrees inclination.

Please use the Starlink Discussion Thread for all general discussion on Starlink.

Check the Starlink Index Thread for links to more Starlink information.

From a previous mission's Press Kit:
Quote
Each Starlink satellite weights approximately 260 kg and features a compact, flat-panel design that minimizes volume, allowing for a dense launch stack to take full advantage of Falcon 9’s launch capabilities. With four powerful phased array and two parabolic antennas on each satellite ... At end of their life cycle, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event their propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years, significantly less than the hundreds or thousands of years required at higher altitudes. Further, Starlink components are designed for full demisability.

Starlink is targeting service to near global coverage of the populated world by 2021. Additional information on the system can be found at starlink.com.

Are there any outward signs yet of a launch campaign?

I also heard nothing of a January mission from Vandy, we will probably have the launch of this mission in February along with NROL-87, though never say never.

SFN Launch Schedule, updated January 10.

Also, NROL-87 is listed in February, no date.

Apparently, plenty of room for a Vandenberg Starlink launch beforehand, if SpaceX desires.

There's no FCC permit for a Starlink mission on January from Vandy, at least that I remember. Not sure where the room is for that...

One other item that I edited into a previous post; cross-posted here:
In addition, given the two first stages currently in use at Vandenberg, 1051.12 and 1063.4, I suspect that 1063.4 will be used for the NRO launch; as the NRO is an "external" customer, and 1051 will be the first booster used for the twelfth time.

[Could be 1071.1 instead.]

I therefore suspect 1051.12 will be used for the next Vandenberg Starlink launch (if it's in the near future).

This could be a launching manifest for Vandenberg (based on my personal knowledge and opinion):

B1071 | NROL-87
B1063 | SARah 1 & Rideshares
B1051 | Various Starlink missions

Circumstantial evidence against a January Vandenberg Starlink launch--fitting a launch campaign within the dwindling days between now and February 2; cross-post:

The launch of the NROL-87 mission is scheduled for February 2 at 16:37 UTC.

I'm leaning more towards 2-2, I'd say 4-2 for Florida, but I may be wrong.

2-2 would imply 70° inclination.

This one is to 53.2° (just like 4-4, which also launched from California).

Note that the name of the mission on the notice has a typo, this is Starlink 4-11 not 4-1 (obvious because we've already seen the launch of 4-1 but noting it just in case)

Possible first stages for Starlink 4-11: 1051.12 or 1063.4.

1063.4 landed on last Nov. 24.  1051.12 landed last Dec. 18.

1071.2 would probably not yet be available, and it is being held for NROL-85.

No other completed and tested first stages are known to be in California.

Static Fire or no Static Fire before launch?  My guess:
Probably yes if 1051.12.  No if 1063.4.

Edit Feb 21: It's 1063.4.  1051.12 returning to Florida.

B1060.11 for Starlink 4-9.

No, but my guess would be 49 (because that's 3 less than the 52 satellites launched on 4-4). Assuming they're sticking to the new higher deployment altitude.

The dogleg maneuver required to get into a 53.2 degree orbit from SLC-4E requires less dV than the dogleg maneuver recent Cape Starlink missions like Starlink 4-8 preformed.

SpaceX is targeting Friday, February 25 for a Falcon 9 launch of 50 Starlink satellites to low Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. The instantaneous launch window is at 9:12 a.m. PST (17:12 UTC), and a backup opportunity is available on Saturday, February 26 at 8:50 a.m. PST (16:50 UTC).


The first stage booster supporting this mission previously launched Sentinel-6 Michael Freilich, DART, and one Starlink mission. Following stage separation, SpaceX will land Falcon 9’s first stage on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.


A live webcast of this mission will begin about 15 minutes prior to liftoff.

That last view shows well the positive angle of attack in flight. Chris G. goofed in the commentary when he called it an optical illusion. The SpaceX webcast shows it too in the view downward from stage 1, when the plumes bend toward the horizon and then straighten again before staging.

Angle of attack, or could it be they are doing some of the dogleg with the first stage?  The slower you are going when you change inclination, the smaller the penalty, so it would pay to do this if possible.  The shape of the safety corridor will determine if a first stage dogleg is possible.

I went down to Gaviota Pass along the south facing cliffs to take advantage of the coast hugging trajectory to get side on views of the booster and particularly the evolution of the first stage plume as it ascended.  My plan worked well under very clear skies.

From this vantage point I was 24 miles from the launch site at liftoff, but the vehicle came to within approximately 15 miles and was only 10 degrees off zenith.

It was also clear that the vehicle was flying at a noticeable angle of attack before staging.

Telemetry and video look good until after the entry burn, then the video dropped out.  I don't believe that is unusual.  The links have improved a lot from the early recovery missions, but dropouts still happen.

Here is a comparison of the Starlink 4-4 and 4-11 webcast telemetry.

1. From their respective Starlink Mission Control Audio webcasts, the ground tracks were indistinguishable. Both indicate a small S2 dogleg after fairing separation.

2. From their respective Starlink Mission webcasts, there was a small difference in the throttle buckets. 4-11 throttled back earlier, and slightly deeper, but there was little difference in the resulting altitude and velocity attained during the booster burns.

3. There were 3 S1 telemetry freezes after the entry burn, visible as steps in the velocity plot.

During the webcast it was said that it was the third flight for both fairing halves (with no more details about specific flights).

I think it hasn't been mentioned in this thread yet.

Yeah, the active half is from NROL-108 and Starlink 2-1, but there weren't any good views of the passive half, so I don't think it can be identified with certainty.

Booster 1063.4 sits atop OCISLY at an unusually vacant Port of Long Beach this afternoon after returning from its Starlink mission from Vandenberg SFB.

CelesTrak has @18SPCS TLEs for 25 of the 50 #Starlink Group 4-11 satellites launched on Feb 25. We expect the remainder soon and IDs to follow shortly thereafter.

Forgot to capture the launches page for this one, so I retrieved the old html from archive.org into the spacex website and pasted the top portion from 4-9 (I guess the image was the same, a certain Nighttime_Starlink_Fairing_DESKTOP.jpg)

The text should be correct tho.

Satellite imagery shows that SpaceX has only just removed B1063 from OCISLY following its flight on February 23rd.

Look closely at the second picture and you can see the booster vertical and its transporter waiting next to it.
