03:18 Attitude nominal.
03:19 TBC pre-set down slew has started.
03:21 Attitude remains nominal.
03:23 Three minutes into the flight of Antares.
03:25 We've got about 15 seconds until main engine cutoff.
03:28 Slow throttle down, steady 55% thrust.
03:40 And we have main engine cutoff.
03:45 Helmets is taking care of business.
03:52 We have stage separation.
03:55 Switching to animation with confirmed stage separation as we lose Antares into the clouds on this hazy evening.
04:02 Stage two ignition time expected at mission time 246.

04:24 Antares currently in a coast phase.
04:29 Stage two ignition and TBC battery is nominal.
04:33 Second stage, solid rocket motor has ignited.
04:36 Power remains nominal.
04:38 This stage will burn for two minutes and 44 seconds.

04:54 Power remains nominal.
05:00 Stage two TBC is nominal.
05:03 Flight controllers reporting good performance on the second stage.
05:11 Power remains nominal.
05:21 TBC remains nominal in stage two.
05:27 And power is nominal.
05:35 We're approximately 100 seconds from stage two burnout.
05:40 Attitude still nominal.
05:44 Attitude remains nominal.

06:25 TBC remains nominal.
06:28 50 seconds to stage two burnout.
06:39 TBC and electrical power remain nominal.
06:56 TBC and power remain nominal.
07:03 Beginning to tail off in the mode of pressure and we have stage two burnout.
07:16 Six minutes, 55 seconds into the flight.
07:19 The second stage solid rocket motor has burned out.
07:24 ACS enabled.
07:26 ACS payload enabled.
07:28 We're now entering about approximately a two-minute coast phase.
07:31 Antares is in orbit and will coast for roughly 100 seconds prior to payload separation.
08:00 Seven minutes, 45 seconds into the flight of Antares.
08:09 After spacecraft separation, it will take approximately two hours, 30 minutes until the solar arrays are unfurled to start collecting power for the Cygnus vehicle.
08:20 Shortly after spacecraft separation, we'll have a representative from the International Space Station program online to provide some comments on the flight of Antares
08:32 and some comments on Cygnus's journey to the International Space Station.
08:36 We plan to wrap our coverage shortly after orbital insertion, but please stay tuned for updates online on the solar array unfurl.
08:45 Spacecraft separation is coming up on 30 seconds.
09:00 Power remains nominal.
09:02 Vehicle continues to coast prior to payload separation.
09:14 And we have payload separation.
09:24 The flight control teams confirmed the visuals you're seeing here on the animation.
09:28 Cygnus has separated from the Antares second stage, flying free and beginning its journey to the International Space Station.
09:42 All right, launch team, LC on countdown net.
09:46 We're going to go ahead and proceed with our post-launch checklist.
09:50 We've confirmed that we've had Cygnus separation.
09:54 Congratulations to the Cygnus team.
09:56 And that sound you heard a little earlier was a mic drop.
09:59 [ Silence ]
