Pretty good show considering the cloud cover. Falcon 9 carrying Starlink group 5-4 to orbit. #SpaceX

The Moon and Falcon rise together!
Ok, that’s cheesy. 😅

That’s another batch of Starlink satellites delivered to orbit atop veteran Falcon 9 B1062, marking its 12th flight.

The Moon hiding behind some clouds as Starlink 5-4 passes by on its way to deliver 55 Starlink satellites. B1062 completed its 12th mission.

AOS Western Australia.

T+54 minutes and 12 seconds. Second stage ignition for two seconds should be occurring about now.

"MVAC ignition and shutdown."

"Nominal orbit insertion."

Expected LOS Western Australia.

Steven Pietrobon · « **Reply #69 on:** 02/12/2023 05:13 am »

T+1 hour, 3 minutes and 15 seconds. Separation should be occurring about now.

Falcon 9 launches 55 Starlink satellites to orbit

Here is a comparison of the webcast telemetry from the Starlink 5-1 and 5-4 missions.

The outstanding difference is the altitude at injection to the coast orbit. Previous shell 5 missions have all inserted at 211-230km, but this mission injected at 152km, lower than any previous SpaceX mission I can find. A quick search suggests the previous lowest altitude was around 164km for several GTO missions like Amazonas Nexus.

This not exceptionally low by historical standards - flight that will go quickly go higher often use (and profit from) very low parking orbits. Apollo 17's perigee was 147 km (91.2 miles).

Into and through the clouds...#SpaceX Falcon9 this morning over Cape Canaveral Space Force Station...I like the way the rocket opened a tunnel for itself in the clouds as it went and through them.

A Shortfall of Gravitas is en-route back to Port Canaveral with B1062, following the successful Starlink 5-4 mission. Doug is towing the droneship back.

Returning late Wed or early Thursday
