#TDRSM, like its two predecessors, makes use of an extended coast phase, targeting a Geotransfer Orbit with increased perigee.

The #TDRSM profile has been tweaked further in response to the introduction of the RL-10C engine, extending the coast by 8.25 minutes.

The slight adjustment to the coast duration is expected to give #TDRSM two additional years of stationkeeping propellant in GEO.

T+plus 42 minutes. Bus and battery voltages, tank pressures and other system measurements look good on the rocket as it coasts in this parking orbit.

Approx 40 minutes into the planned ~90-minute coast phase. Continuing to look good. #AtlasV #TDRSM

Создателей РД-180 можно поздравить с ещё одним двигателем, отработавшим нормально?

T+plus 1 hour, 6 minutes. Tank pressures remain stable on Centaur. More than half of this 90-minute coast period has elapsed.

Ten minutes to the critical Centaur re-start, occurring between perigee & apogee to lift the altitude of both. #TDRSM
