00:00And there's the retraction of that first umbilical.
00:18T-minus 25 seconds and counting, just a few seconds away from the second umbilical retracting
00:24that begins the engine sequence start.
00:30And we have engine ignition.
00:37The engine's coming up to flight speed. Five, four, three, two, one.
00:46And liftoff. Liftoff of the Progress 92 cargo craft bound for the International Space Station.
01:00The Soyuz booster arcing out to the northeast. Roll pitch and yaw all nominal.
01:14Engine performance nominal as the Soyuz heads downrange.
01:1737 seconds into the flight, all parameters reported to be normal from the blockhouse in Baikonur.
01:35Punching a hole through the clouds, heading into an orbit 51.6 degrees inclined to the equator.
01:39The engine chamber pressure is nominal.
01:47We've passed the one minute mark into the flight.
01:51Yaw, pitch and roll all reported to be nominal.
01:53Passing through the area of maximum dynamic pressure on the vehicle.
02:06One minute 25 seconds into the flight.
02:09About 25 seconds, uh, remaining in first stage performance.
02:25Stop.
02:26Everything looking good on the Soyuz booster standing by for first stage set.
02:45And we have confirmation of first stage separation on time.
02:48Two minutes, 16 seconds into the flight.
03:05Second stage up and running, good stabilization on the vehicle reported.
03:09So far, all of the structural parameters reported to be normal from the engineers at the blockhouse in Baikonur.
03:25Second stage performance is by the book, according to the engineers.
03:29Six minutes of powered flight remaining.
03:55Three minutes, 11 seconds into the flight.
03:57Everything going well.
03:58The launch shroud has been jettisoned.
04:04The progress being propelled uphill on the power of the second stage engine on the Soyuz 2.1A booster.
04:15Three and a half minutes into the flight.
04:27Five minutes of powered flight remaining.
04:33Nothing but good reports coming from the blockhouse in Baikonur so far.
04:44We've now passed the four minute mark into the flight.
04:47The liftoff time was right on the money at 2.32 and 40 seconds p.m. Central Time.
04:55Second stage performance continues to be nominal, according to the engineers in Baikonur.
05:01You're looking at a live view from a balcony camera at the Russian Mission Control Center in the town of Koryov on the outskirts of Moscow.
05:09So those flight controllers will take over control of the vehicle.
05:14The progress itself following its separation from the third stage of the Soyuz booster.
05:21And we have confirmation of the shutdown of the second stage engine.
05:42The Soyuz being propelled now by the third stage engine.
05:45There you see the second stage, the third stage skirt jettison and that view on the center screen of the Russian Mission Control Center.
05:56Five minutes, 15 seconds into the flight, everything looking good so far.
05:59Five and a half minutes into the flight, so far so good.
06:20The progress being propelled uphill by its third stage engine on the Soyuz 2.1A booster.
06:27Three minutes of powered flight remaining.
06:36Now we have a better view from the camera on the upper stage of the Soyuz booster.
06:43If we hold this view, we should be able to see third stage shutdown, spacecraft separation,
06:49and the deployment of the solar arrays on the progress itself.
06:55Six minutes, 15 seconds into the flight, two and a half minutes of powered flight remaining.
06:59The third stage engine performance is nominal.
07:12Third stage engine performance is nominal.
07:15Six minutes, 48 seconds into the flight, just two minutes of powered flight remaining.
07:37So far, everything is gone by the book, all of the milestones having been passed in trip
07:43hammer fashion.
07:55The yaw, pitch, and roll, all good, good structural stability on the Soyuz booster's third stage.
08:03Seven minutes, 20 seconds into the flight.
08:08Seven minutes, 45 seconds into the flight, one minute of powered flight remaining.
08:19We're expecting third stage shutdown at the eight minute, 45 second mark, followed just
08:37seconds later by spacecraft separation.
08:44Passing eight minutes into the flight.
08:55Eight minutes, 15 seconds into the flight, 30 seconds of powered flight remaining.
09:04All the parameters on the third stage looking good.
09:20The third stage engine beginning to tail off now as we stand by for third stage shutdown
09:24and spacecraft separation.
09:32Third stage shutdown confirmed.
09:36The command should be issued momentarily for the initiation of the deployment of the solar
09:48rays and navigational antennas on the progress.
09:52And there they go.
