Stage 1 landing burn has started. For typical GTO landings, the booster uses a 1-3-1 engine sequence for efficiency.

Meanwhile, SECO-1 has occurred and the vehicle is in a slightly elliptical parking orbit.

As for Stage 2, between SECO-1 and the M-Vac engine restart, there is a coast phase lasting 18 minutes and 9 seconds. At the time of engine restart, the vehicle will have made its first pass over the Equator.
