SpaceX confirms deployment of 46 new Starlink internet satellites, completing the 58th dedicated launch for the privately-funded broadband network.

SpaceX has now launched 3,208 Starlink satellites, including spacecraft already retired from service.

Here is a comparison of the webcast telemetry from the Starlink 3-3 and 3-4 missions.

The most recent Starlink 4-27 mission demonstrated increased second stage performance, but this mission demonstrates unprecedented first stage performance. Despite throttling back early for a wider throttle bucket, the 3-4 booster thereafter showed increased thrust up until terminal guidance, and MECO was at 2292m/s, some 30 m/s faster than for 3-3.

It will be interesting to see what Falcon 9 can do when both stages are pushed to their new maxima.

Thanks for the overnight (US) coverage Steven, and the data analysis OneSpeed. You guys are what makes NSF the best.

If someone is tracking when things happen in the countdown, LOX load was finished later than usual on both stages for this mission. This is one of the things they're doing now to pack more propellant on the tanks
