Here is a comparison of the webcast telemetry from Starlink 4-27 and 4-20.

Although 4-20 may have utilised a late load of propellant, there was no evidence of the increased acceleration evident in 4-27 or 4-23. The 4-20 booster landed some 40km less distance downrange, velocity at MECO was some 43m/s less, and peak S2 acceleration was 3.8g vs 4g for 4-27.

Overall, it was a much more relaxed affair.

Update: Happy to report Sherpa-LTC made contact on its first pass last nite (while I was sleeping) and is proceeding through its checkouts. Stay tuned for more progress reports! (Photo credit to the talented @johnkrausphotos)

That's cool tracking. Presumably the same payload, etc on the two flights?

One suggestion, if I may. This sort of image would probably work particularly well in PNG format, which uses lossless compression, rather than JPG.

Cheers, Martin

Per webcast, fourth and fifth flight for those fairing halves.

CelesTrak has ephemeris-based SupGP data for all 51 satellites from the launch (2022-107) of #Starlink Group 4-20 from Cape Canaveral on Sep 5 at 0209 UTC:

This morning, we saw the recently launched Starlink satellite (Starlink Group 4-20)! It looks like it was taken from my home in Hiratsuka at 4:15 on September 6, 2022. There will also be a launch on the 11th, and AST's BlueWalker 3, which will be on board, is equipped with a 10m diameter antenna for direct communication with smartphones. It may look brighter.

Starlink 4-20: Just Read the Instructions droneship is underway towards Port Canaveral with B1052

ETA ~approx Thursday morning.

Going to be a tight turnaround. Starlink 4-23 is reportedly NET Sep 12th using JRTI droneship.

This morning, I was able to take a picture of the Starlink satellite (Starlink Group 4-20) through the clouds! It looks like it was taken from my home in Hiratsuka at 4:26 on September 7, 2022. The interval has widened compared to yesterday. It will be easy to see on the evening of September 9, and will rise in the southwestern sky before 7:30 pm.

The @SpaceX launch support vessel Doug is currently in the Port Canaveral entrance channel after a busy Starlink 4-20 launch period. I am thinking some gently used payload fairings may be aboard.

SpaceX's Doug returned from the Starlink 4-20 mission this morning with two fairing halves

Bonus: Check out American flag the crew are flying from the crane boom!

JRTI should deliver B1052 to Port Canaveral around/after 8am ET on Thursday morning. Tug Kurt Crosby is towing.

While the booster that had been standing on Port for days finally got positioned on the transporter to be returned to Hangar X for refurbishment, Doug returned with 2 recovered fairings from the Starlink 4-20 mission. Both fairings were in good condition.

After #Starlink 4-20 #Falcon9 B1052 had returned to @PortCanaveral just as rain has started to fall.

Spectacular light show at Port Canaveral yesterday mostly between 6:30 and 6:40 PM EDT. Lightning 'touchdowns'. Even the container crane got a hit.
