00:00 We are now one minute away from launch of the Progress 86 spacecraft atop a Soyuz 2.1a
00:07 booster.
00:08 The booster is now on internal power.
00:17 In just about 10 seconds we will see retraction of the first umbilical and these are the towers
00:22 that have buttressed up against the upper stage of the rocket.
00:30 And there we have retraction of the first umbilical.
00:33 The second umbilical will retract in about 13 seconds and this will initiate engine start
00:39 sequence.
00:47 We are 15 seconds away from launch.
00:53 Second umbilical has retracted and the engine sequence has started.
00:56 Engines are coming up to full throttle.
01:07 And liftoff of the 86 Progress resupply vehicle for its 34-orbit journey to the International
01:12 Space Station.
01:20 Engines on the first stage are operating as expected.
01:26 Booster systems are also operating as expected.
01:41 The structural parameters of the vehicle are normal.
01:43 The vehicle continues to be stable.
02:04 The vehicle continues to be stable and we are about a minute away from first stage shutdown
02:08 and separation.
02:13 Roll pitch and yaw of the vehicle are normal.
02:23 We are a minute and 20 seconds into the flight and everything is proceeding as expected.
02:46 Engines of the first stage continue to operate as expected.
02:48 We are standing by for first stage shutdown and separation.
03:06 We have confirmation of first stage shutdown and separation.
03:09 The vehicle is currently traveling 4,500 miles per hour and 29 miles in altitude, 29 miles
03:16 downrange from the Cosmodrome.
03:33 The vehicle continues to be stable and all structural parameters are normal.
03:43 We are about 20 seconds away from launch shroud jettison.
03:48 Engines in the second stage are operating as expected.
03:56 We are about a minute and 20 seconds into the flight and everything is proceeding as expected.
04:05 The vehicle is currently traveling 4,500 miles per hour and 29 miles in altitude, 29 miles
04:25 downrange from the Cosmodrome.
04:26 We have confirmation that the launch shroud successfully jettisoned.
04:32 The second stage engine continues to operate as expected.
04:37 In about one minute we will see second stage shutdown followed shortly thereafter by second
04:41 stage separation and third stage skirt jettison.
04:44 We are now four minutes into today's flight and everything continues to proceed as expected.
