1 minute into the flight. About 30 seconds remaining in the SRBs, which should burn out at T+91 seconds. They will be jettisoned in sets of two within 2.4 seconds.
This is Recovery; the center core has landed. All landing operators, proceed to Procedure 11.000 on ECRY and ECF9 Net.

We have burnout on all four SRBs.

And jettison has occurred. The main engine continues to burn well at 108.5% of rated thrust.

The next major event will be payload fairing jettison at the 199-second point.

Realtime telemetry of the vehicle is being called out by Patrick Moore in the Mission Director's Center.

Both fairing halves have been jettisoned, exposing the satellite to space for the first time.

In a few seconds, the main engine will be throttled down from 108.5% to 58% in preparation for MECO. This will help limit acceleration stresses on the payload.

We have MECO on time.

The first stage has been discarded and the RL-10 nozzle is being deployed.

We have LOX and LH2 prestart in work.

We have the first ignition of the RL-10 engine. This first burn will last over 15 minutes to insert the vehicle into a slightly elliptical parking orbit.

Talking about WGS. Talking about antijam engancements.
