What is said in the film

Rob: anne: rob: you are looking live at launchpad 6, site 31 in kazakhstan where a three-stage soyuz 2. 1a booster stands fully fueled ready for launch just 22 minutes from now on a two-day journey to deliver 2. 8 tons of food, fuel and supplies for the residents of the international space station. Good afternoon from mission control in houston and the international space station flight control room. That is soyuz booster was fueled for launch several hours ago by technicians down in baikonur in the central asian desert.

It is just after midnight baikonur time on the fourth of july. It is quite sultry in this summer evening out there, 90degrees. Partly cloudy skies for the liftoff of the soyuz and the progress 92 resupply craft that launched scheduled at 2:32 and 40 seconds p. m. Central time and that is 32 minutes and 40 seconds after midnight baikonur time on friday morning.

The soyuz booster and the progress resupply craft encapsulated in the super stage of the three-stage rocket rolled out to the pad on tuesday, where technicians worked to hook up electrical lines and fuel lines to make time preparations for the liftoff of the progress, that launch will carry the soyuz booster arcing out to the northeast of the baikonur cosmodrome to 51. 6degrees to either side of the equator. Again, beginning a 34-orbit two-day journey to reach the international space station for what is expected to be automated docking at 4:27p. m. Central time on saturday afternoon.

The soyuz booster is emblazoned with the logo which is just two weeks away from marking the 50th anniversary of that historic spaceflight. On july15th, 1975, the soyuz spacecraft with alexey launched first from baikonur followed 7. 5 hours by the apollo spacecraft with three onboard. That was the precursor the international cooperation that has existed for the past five decades and of course, which is seen today aboard the international space station. Onboard the station at that hour, the expedition 73 crew led by takuya onishi from the japan aerospace exploration, three astronauts anne mcclain, nichole ayers and jonny kim and three roscosmos, sergey ryzhikov, alexey zubritsky and four members of the astronaut mission former peggy whitson, india's shubhanshu shukla and poland's slawosz uznanski-wisniewski and tibor kapu on saturday afternoon.

We are minutes. Leading to the liftoff itself will occur at the t minus 35 30 second mark when launch control will report that the range in baikonur is clear, that the soyuz rocket is ready to begin its journey. About 30 seconds later, onboard systems will be switched to onboard control. And that the t minus 4 minute mark, the fall lines, the rocket engines will be purged with nitrogen to fireproof them by removing vapors of fuel and oxidizer. About a minute 15 seconds after that, the t minus 2:45 mark, the booster's fuel tanks will be pressurized for flight, optimizing the flow of fuel, helping to add structural support to the rocket.

The ground propellent feed will be terminated at the t minus 1:30 mark just before the soyuz booster is placed on internal power. About 35 seconds before liftoff, the first of two that will initiate auto sequence start about 15 seconds later the second umbilical tower will be retracking as well, and that will initiate engine starr. The engines will come up to flight speed the holddown posts will be retracted the soyuz booster and the progress 92 spacecraft will be on their way. The progress is also now on autonomous power, down in baikonur. The first 8:45 of flight to deliver the progress into the preliminary orbit, where it will deploy the solar arrays and navigational antennas, the launch phase is operated by the engineers at the blockhouse in baikonur, as soon as the progress reaches orbit and separates from the third stage of the soyuz booster control will be turned over to the flight control team at the russian mission center in korolyov, and on the outskirts of moscow for the rest of the two-day journey to the international space station.

There you can see the view from the balcony camera overlooking the international space station flight control room outside of moscow and you can see, on lower right-hand corner of the front screen, that is the apollo soyuz logo, just as it is emblazoned on the side of the soyuz booster marking the 50th anniversary of the apollo soyuz mission. You are hearing communications from the blockhouse in baikonur. Of course, this is uncrewed vehicle carrying 3. 8 tons of food, fuel and supplies and will dock on saturday afternoon to the poisk module on the space facing side of the russian segment of the international space station. That docking port, was vacated on july first, two days ago, with the departure and the deorbit of the older progress 90 cargo craft, that had arrived at the station a few months ago.

So progress 92 will dock to the poisk module, that is scheduled to be automated docking, with the link-up scheduled on saturday afternoon at 4:27p. m. Central time. 5:27p. m.

Eastern time. We are approaching the t minus 15 minutes mark in the countdown. Again, everything has been going smoothly. We are expecting a liftoff at 2:42 and4p. m.

Central time. And 32 minutes and 40 seconds after midnight on thursday on friday, I should say, in baikonur. Some of the ascent milestones you will be hearing as we go uphill with the progress 92 cargo craft, the first stage of the three-stage soyuz booster will separate at the 1:57 second mark at the 3:04 mission mark, the launch shroud will be jettisoned. That is the shroud basically, the clamshell-like shroud that encompasses, envelopes the progress, at the top of the third stage of the vehicle. Second stage shutdown will occur at the 4:37 mark into the flight, followed 10 seconds later by the separation of the second stage.

The third stage engine will be burning at that point. The enveloping the third stage of the soyuz booster will separate at the 4:57 second mark and the last milestone of 6:45 into the mission. The third stage separation of the soyuz booster from the progress will occur four seconds later at 8:49 followed seconds later by the command to deploy the progress' solar arrays and navigational antennas. For a 34 on orbit two-day journey the launch window is 25 seconds long. You can see the soyuz venting liquid oxygen from the first stage of the booster.

Everything is proceeding on track as we approach the t minus 13 minute mark in the countdown. Once the progress arrives at the international space station for its automated docking to the poisk module on saturday afternoon, the cosmonauts aboard the station will conduct leak checks at both sides of the docking interface between the progress and poisk before opening the hatch and beginning the process of unloading the cargo that is onboard, again, 2. 8 tons of food, fuel and supplies for the crewmembers onboard the international outpost. This progress resupply vehicle is expected to remain docked to the station for approximately six months or so before it departs much later this year. This delivery run once again part of the continuing chain of resupply craft that maintained an ongoing supply of food, fuel and supplies and dry goods for the crewmembers onboard the station, along with a surplus that is used to prevent any short fall of any food or other supplies for the crewmembers onboard the international complex.

Once the progress arrives in the preliminary orbit, a series of preprogrammed engine firings called dv burns or delta velocity burns will be conducted that will incrementally raise the altitude of the progress to match that of the international space station before we go into what is known as automated rendezvous operations at mid afternoon on saturday. At the moment the international space station and the 11 occupants are flying 260 statute miles over the south pacific about to begin a southwest and northeasterly swing in orbit inclined 51. 6 degrees to earth side of the equator. Approaching nine minutes 45 seconds before liftoff. Once again, you can barely make it out, but can see the umbilical, one of the two umbilicals that is up against the side of the soyuz booster, the 2.

1a booster on launchpad 6 on site 31 in baikonur, that taller of the two umbilicals will retract at about the t minus 35 second mark followed by some 20 seconds later of the second umbilical that will trigger the beginning of the engine firing sequence that will enable the engines on the first stage to come up to flight speed, and command the posts to be released allowing the soyuz to take flight. All is quiet here on the international space station flight control room at mission control. Flight director fiona polled her team of flight controllers of the orbit 2 team about 40 minutes ago and gave a go for launch, that was relayed to the russian flight control team of the russian mission control center outside of moscow and we just passed the 8 minute mark in the countdown. All quiet at the block house in baikonur. A number of actives about to get underway over the next few minutes in preparation for engine ignition and liftoff.

Rob: countdown clocks continue to tick backward at t minus 6:45 before launch. Rob: t5:45 before launch. We are coming up in the milestone of launch control down at baikonur reporting that the range is clear and that the soyuz rocket is ready to begin its journey. We are at the t minus 5 minute mark in the countdown onboard systems now switching to onboard control in the soyuz booster. Again, this is a three-stage rocket, the first stage will burn for about a minute 57 seconds before separating.

The second stage engine will have ignited to continue the journey uphill for the progress and 8:45 journey to deposit the resupply craft into the preliminary orbit. Passing the t minus 4 minute mark in the countdown. The fuel line on the soyuz and other limbs of the rocket engines now being purged with nitrogen. Everything ready in baikonur for a midsummer's night launch to deliver the progress 92 cargo craft and 2. 8 tons of food, fuel, supplies to the residents of the international space station.

Approaching the t minus 3 minute mark in the countdown. Mark t minus 3 minutes. The booster's fuel tanks soon to be pressurized for flight. T minus 2:30 and counting. T minus 2 and counting.

Two minutes from launch. A few seconds from now the ground propellent feed will be terminated to the rocket. The booster and the progress itself on autonomous power. T minus 90 seconds. Coming up on the one minute mark.

Mark one minute and counting. 20 seconds away from the umbilical retraction. There is a retraction of the first umbilical. T minus 25 seconds and counting, just a few seconds away from the second umbilical retracking that begins the engine sequence start. And we have engine ignition.

The engine is coming up to flight speed. 5, 4, 3, 2, 1. And liftoff liftoff of the progress 92 cargo craft bound for the international space station. The soyuz booster marking out to the northeast, roll, pitch all nominal. Engine performance nominal as the soyuz heads down range.

37 seconds into the flight, all perimeters reported to be normal trillion the blockhouse in baikonur. Punching a hole through the clouds heading into orbit 51. 6degrees and flying to the equate ore. Equator. Engine chamber pressure is nominal.

Past the one minute mark into the flight. Pitch and roll all reported to be nominal. Passing through the area of maximum dynamic pressure on the vehicle. 1:25 into the flight. About 25 seconds remaining in first stage performance.

Everything looking good on the soyuz booster standing by for first stage set. And we have confirmation of first stage separation on time. 2:16 into the flight. Second stage up and running. Good stabilizing on the vehicle reported.

So far all the structural parameters reported to be normal from the engines near at the blockhouse in baikonur. Second stage performance is by the book according to the engineers. Six minutes of powered flight remaining. 3:11 into the flight. Everything going well.

The launch shroud has been jettisoned. The progress being propelled uphill on the power of the second stage engine on the soyuz 2. 1a booster. Three and a half minutes into the flight. Five minutes of powered flight remaining.

Nothing but good reports coming from the blockhouse in baikonur so far. Four minute into the flight. The liftoff time was right on the money at 2:42:40p. m. Central time.

The second stage performance continues to be nominal according to the engineers in baikonor. You are looking at a live view from the balcony camera, at the russian mission control center in the town of korolyov on the outskirts of moscow, those flight controllers will take over control of the vehicle, the progress itself following its separation from the third stage of the soyuz booster. And we have confirmation of the shutdown of the second stage engine. The soyuz now being propelled now by the third stage engine. There you see the second stage, the third stage skirt jettisoned and that view on the center screen of the russian mission control center.

5:15 into the flight. Everything looking good so far. Five and a half min nines into the flight. So far, so good. The progress being propelled were up hill by the third stage engine on the soyuz 2.

1a booster, three minutes of powered flight remaining. Now we have a better view from the camera on the upper stage of the soyuz booster. If we hold this view, we should be able to see third stage shutdown, spacecraft separation, and the deployment of the solar arrays on the progress itself. 6:15 into the flight. Two and a half minutes of powered flight remaining.

Third stage engine performance is nominal. 6:48 into the flight. Just two minutes of powered flight remaining. So far, everything has gone by the book all of the milestones having been passed and trip hammer fashion. The pitch and roll all good.

Good structural ability on the third stage. 7:20 into the flight. 7:45 into the flight. One minute of powered flight remaining. We are expecting third stage shutdown at the 8:45 second followed seconds later by spacecraft separation.

8:15 into the flight. 30 seconds of powered flight remaining. Al the perimeters on the third stage looking good. The third stage engine beginning to tail off now as we stand by for spacecraft separation. Third stage shutdown confirmed.

And spacecraft separation. The command should be issued momentarily for the initiation of the deployment of the solar arrays and navigational antennas on the progress. And there they go. And we have confirmation that all of the two solar array and all of the navigational antennas have now been deployed, so it was an uneventful, smooth ride uphill for the progress 92 cargo craft. It is now on its way for a two-day journey and delivery run ton the international space station.

Once again, the launch occurred on time at 2:23:40p. m. Central time. That was 32 minute 40 seconds a. m.

Right after midnight at baikonur on friday morning. The progress soon, as we see the first view from the external tv camera on the progress, looking out at the lymph the earth, that camera will come into more significant use on saturday during the final phase of rendezvous and the docking of the progress to the poisk module on the space facing side of the russian segment of the international space station. And the progress' cores automated rendezvous system is now in the test mode per the timeline. If all goes as planned, the progress will reach the neighborhood of the international space station at mid afternoon on saturday, and begin a fly-around of the station to align its forward docking probe with the poisk module for an automated link-up to the poisk at 4:27p. m.

Central time, 5:27p. m. Eastern time. Back here in the international space station flight control room here in mission control in houston, the orbit 2 team of flight controllers, now settling in for the remainder of its shift for the day. It has been an off-duty day for the crew onboard the international space station.

2:32:40p. m. Central time. Everything went perfectly on the orion uphill and 8:45 to deliver the progress into the preliminary orbit. The progress will now execute a preprogrammed series of engine firings to raise its altitude eventually to match that of the international space station for the final phase of the rendezvous and the eventual docking of the progress the poise module on saturday afternoon.

With that, here is a look at the docking coverage on nasa plus on saturday. We will go on the air at 4:45p. m. Eastern time. 3:45p.

m. Central. Docking is expected at 5:27p. m. Eastern time.

4:27p. m. Central time on saturday. So amidst the holiday weekend plans, please tune in to us on saturday, and we'll bring you along as the newest cargo craft arrives at the international space station with 2. 8-tons of food, fuel and supplies?

For now, we'll sign off for the coverage of this launch of the progress 92. Have a great fourth of july. That is it. We'll sign off. This is mission control in houston.
