T+2 minutes and 17 minutes. AOS Mauritius.

T+2 minutes and 18 minutes. Nominal deorbit burn.

T+2 minutes and 19 minutes. Separation of Starlinks confirmed!

That was very strange. Were the Starlinks deployed after the deorbit burn? Also strange that for both BlueWalker 3 and the Starlink satellites, deployment was scheduled a few seconds after LOS. Also, at Malindi AOS there was no immediate confirmation of Starlink deploy and we had to wait until after confirmation of the deorbit burn.

Confirmation of deployment by SpaceX.

"Deployment of 34 Starlink satellites confirmed"

The methodology to read telemetry is to start with the AOS and go backwards in time and read off events. The last item to occur is first to be read off.

Thanks for that information, but SpaceX doesn't always follow that order. For example, at Tasmania AOS, BlueWalker 3 separation was read out first, followed by the AOS call!

Here is a comparison of the webcast telemetry from the Starlink 4-2 / BlueWalker-3 mission and 4-20 / Sherpa-LTC2.

Both missions were rideshare, to similar orbital inclinations, with BlueWalker-3, at some 1.5t being the heaviest rideshare payload so far.

The booster profiles were similar, neither of them demonstrating the performance improvements of the recent 4-27 and 4-23 'pure' Starlink missions.

However, the 4-2 second stage demonstrated a similar burn time to those 'pure' missions, indicating an increased appetite for pushing the Falcon 9 performance envelope for paying customers.

Please compare 4-2 and globalstar fm-15 also so that knowing the timings of engine ignition will mapped

Liftoff! Falcon 9 launches 34 Starlink satellites and AST SpaceMobile’s BlueWalker 3 satellite at 9:10 p.m. EDT this evening.

This launch marked the first 14th flight of a Falcon booster!

SpaceX's most-flown Falcon 9 booster -- numbered B1058 -- launched and landed for the record 14th time tonight. This rocket debuted in 2020 with the first launch of astronauts on the Crew Dragon capsule.

Here's a snapshot of this rocket's flight history.

BlueWalker 3 is comfortably roaming around the globe, thermally stable and communicating with our ground stations! If you want to learn more about what's next, please take a look at this video: https://youtube.com/watch?v=uUBiGseRDw4 🤠🇺🇸📶#5G

Update / Update

First time a booster is launched/recovered 14 times. That is already amortized.
