And M-Vac has shut down after a 58-second burn. Standing by for the GNC controller to verify a good GTO.

S/C Sep! Merah Putih (Telkom 4) has been separated following launch on the Falcon 9 Block 5 B1046.2 - which also landed on OCISLY.

ARTICLE: https://www.nasaspaceflight.com/2018/08/spacex-falcon-9-merah-putih-block-5-reflight/ - by William Graham.

As always (well recently) all congrats posts/questions and non-updates to be posted on the other threads. This remains updates only.

Thanks to Chris G, Steven, Zach and all for the coverage!

Online ZachS09

Merah Putih separation confirmed via telemetry and the forward-facing camera.

The 5,800-kilogram satellite will proceed to raise its perigee to 35,800 kilometers and lower the inclination to 0 before beginning its 15-year mission, which might be extended based on fuel usage.
