And we have MECO-1 on schedule. Stages have separated; good luck to Core B1046.

The M-Vac engine has ignited for the first of two burns. This first burn will last 343 seconds until T+8 minutes, 19 seconds.

Stage 1 grid fins have deployed as the booster slowly maneuvers to reentry attitude.

T+3 minutes, 37 seconds. Payload fairing has been jettisoned. Stage 2 propulsion is nominal.

Awesome fish-eye camera views from the second stage.

First stage separation.

T+3 minutes.

4 minutes into the flights of Core B1046 and Bangabandhu 1. The Bermuda tracking station now tracking the vehicles.

Next major event will be the Stage 1 entry burn at T+6 minutes, 15 seconds, which will slow the booster to just faster than the speed of sound. Typical entry burns during a GTO mission last about 20 seconds.

Improved cameras it seems. 1-2!

Fairing separation.

T+4 minutes.

T+5 minutes. Stage 1 and Stage 2 power and telemetry look good.

Altitude 147 kilometers, velocity 11,500 kilometers an hour.

T+5 minutes.

T+6 minutes. Standing by for the entry burn to begin. Stage 1 AFTS will be safed in a few seconds.

ZachS09 · « **Reply #291 on:** 05/11/2018 08:20 pm »

Stage 1 entry burn has started. This burn uses a 1-3-1 engine sequence.

Steven Pietrobon · « **Reply #292 on:** 05/11/2018 08:20 pm »

T+6 minutes.

Stage 1 entry burn has ended. We'll briefly lose video and telemetry of the booster before the Of Course I Still Love You drone ship acquires signal.

ZachS09 · « **Reply #294 on:** 05/11/2018 08:21 pm »

T+7 minutes. Stage 2 propulsion continues to look good.

Shortly before SECO-1, the second stage will enter Terminal Guidance mode and safe its AFTS.

Entry burn.

T+7 minutes.

Stage 1 is transonic. Landing burn is coming up.

ZachS09 · « **Reply #297 on:** 05/11/2018 08:22 pm »

Stage 1 landing burn has started. As expected, the cameras on the drone ship will lose signal due to the heavy vibrations from the engine thrust and the fact that a satellite link is being utilized.

ZachS09 · « **Reply #298 on:** 05/11/2018 08:22 pm »

Stage 1 landing legs deploying. Coming up on touchdown confirmation.

Steven Pietrobon · « **Reply #299 on:** 05/11/2018 08:22 pm »

T+8 minutes. Landing burn has started.
