U.S. Astronaut, Crewmates Close Spacecraft Hatch Ahead of Return to Earth

NASA astronaut Tracy C. Dyson and Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub closed the hatches of their Soyuz MS-25 spacecraft on Sept. 23 ahead of undocking from the International Space Station’s Prichal module. The trio will return to Earth a few hours later for a parachute-assisted landing on the steppe of Kazakhstan. During her mission, Dyson spent 184 days in space living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions as part of NASA’s Moon and Mars exploration approach, including lunar missions through NASA’s Artemis program. Kononenko and Chub landed after spending 374 days in space. Video Courtesy: NASA Center Contact: Sandra Jones, 281-483-5111 HQ Contact: Joshua Finch, 202-358-1100 For more info: www.nasa.gov/station

What is said in the film

and good morning from Mission Control in Houston in the International Space Station flight control room at the Johnson Space Center where at this hour flight controllers working with their colleagues at the Russian Mission Control Center in the town of carof on the outskirts of Moscow are preparing to bid a farewell to three of the crew members on board the International Space Station for their return back to Earth on the soyu ms25 spacecraft the soyu ms25 which is docked to the prall node module uh which in turn is linked to the naoka multi-purpose laboratory module on the earth-facing side of the Russian segment of the international space station is the ticket home tonight for NASA's Tracy Dyson and two Russian cosmonauts from roscosmos Alig kenko and Nikolai chub kenko and chub are completing a an ISS record 374 days in space since they were launched uh over a year ago in September of 2023 Tracy Dyson is wrapping up a mission of 184 days in duration 182 days aboard the International Space Station in terms of the statistics Dyson returning home tonight after having completed 2,944 orbits of the Earth in a mission that will have Spann 78 million statued miles in this her third flight into space konun Yenko and Chu uh will be completing 374 days in space 5,984 orbits of the earth a mission that will have spanned 158. 3 million statued miles and again uh kenko and Chu eclipsed the former endurance record for any single ISS Mission this past Friday when they went past the 371 day Mark that was set a year ago by Sergey procopio Dimitri patelan and NASA's Frank Rubio the uh three departing crew members placed their soyu spacecraft on autonomous power about 35 to 40 minutes ago as they are preparing to say farewell to the other nine crew members on board the International Space Station the new station Commander Sunny Williams uh joined by Matt Dominic Mike Barrett Janette EPS Don Pettit and uh Butch Wilmore and Ros Cosmos cosmonauts Alexi oin Ivon Vagner and Alexander grenen on Sunday morning kenko who is completing uh the third command of the International Space Station that he has held handed over the Keys of the Kingdom to Sunny Williams the NASA astronaut who now is the new space station commander and commander of the International Space Station for the second time let's take a look back at the Sunday morning change of command ceremony okay Houston I would like to thank all space agen space agenes and Mission Control Center for uh the great help and uh support from the ground thanks to all my crewmate for your friendship uh it has been a great time to work and a great pleasure to work uh and spend time uh uh together here as a big family in uh on board in the space uh station and right now I'm leaving my second home as a space station in Sanitas delicate hands I pass you uh the key to the International Space Station and some V in Russian uh C Willams so I guess I get to say a couple words so I appreciate it ALG this uh Expedition 71 has taught all of us a lot about uh flexibility um the ability to adapt to a number of amazing things um um a lot of things weren't planned and somehow you guys put it all together and did it it's it's pretty amazing pretty impressive uh you adopted Butch and I even though that was not quite the plan but here we are as part of the family you welcomed uh don Alexi and Ivonne uh with open arms and uh with your soyu's crew and crew eight you have made this a great family we appreciate it ALG we'll miss your hundreds of stories around on the dinner table but I guess that's what you get for having over a thousand days in space you get those stories right uh coia we're going to miss your Precision your professionalism but I guess that's what you get when you sign up for your rookie flight AS over a year in space and Tracy we're going to miss your desk and your organization and your ability to make order out of chaos even in the the craziest of times so we thank you all three of you for that so I'm going to try and station Houston uh thank you we'll be resuming normal operational audio uh 12 years and 7 days ago was the last time Sunny had the keys in her hand uh glad to have him back that was uh spacecraft Communicator Mike Jensen on Sunday morning uh relaying the fact that Sunny Williams who's now the commander of the International Space Station first became a station Commander during Expedition 33 just over 12 years ago one other note uh for the returning crew Al Konan Yenko comes back to Earth uh on Monday morning with 1,111 days in space on his five space flights including three commands of the International Space Station he and roscosmos cosmin foda yurin are the only two people who have commanded the station three times other two-time commanders include Scott Kelly Alec kotov Anton shapov pavl vinegrad off Peggy witson and Jeff Williams as the international space station flies 260 Mi uh over the southern Indian Ocean about to begin a Southwest and North easterly track that will carry it across the equator a short time from now in an orbit incline 51. 6 de to either side of the Equator Airborne on a Russian antinoff 26 aircraft are the Ros aviaa search and Recovery forces and the NASA team uh that is is embedded with them uh to support uh this morning's recovery of the uh soyu ms25 crew at the time of undocking that is scheduled for 3:36 and 302s a. m. Central Time 436 and 32s a.

m. eastern time Expedition 71 will come to an end and Expedition 72 will formally begin the uh current deorbit burn time is is scheduled at 6:05 and 46 seconds a. m. Central 7:05 and 46 seconds a. m.

eastern time that will be a 4minute 39 second retrograde firing of the soyu engines uh to slow the soyu down by 128 m/s allowing it to drop out of orbit for its descent back into the Earth's atmosphere landing on the step of Kazakhstan in a remote site about 91 miles to the southeast of the town of jez kazgan is scheduled at 6:59 and22 seconds a. m. Central 7:59 and 22 seconds a. m. eastern time which will be 45922 Kazakhstan time about 1 hour and 13 minutes before sunset at the Landing site we'll talk a lot more about the landing operations uh as the morning uh unfolds uh as uh as mentioned earlier the NASA team is aboard a an antinoff 26 aircraft uh they are flying it's about a 2hour and 15minute flight from the staging city of karaganda Kazakhstan down to jez kazgan jez kazgan is in the south central region of Kazakhstan that's where the Russian mi8 helicopters are pre-staged uh the uh Team of search and Recovery forces including the NASA team will get off that Anton off they'll spend uh a short time in the jez kazgan airport before they board the Russian mi8 helicopters for what will amount to about a 25-minute flight down to The Landing Zone they will arrive in a racetrack pattern around the landing Zone waiting for the soy to descend under its main parachute and once the soyuz has touchdown to complete this Mission uh the helicopters will land in sequential fashion and the teams will begin the process of extracting Dyson kononenko and chbe from The Descent module of the soy uh compliment uh they will uh allow uh the crew to have uh several minutes uh to get their land legs back if you will uh for konun Yenko and Chu this is the first time that they will experience gravity in more than a year for Tracy Dyson her first uh sensation of gravity in more than 6 months in space they'll will be uh brought out of the soyu and put in uh chairs uh by the spacecraft and once they have regained a bit of equilibrium they'll be carried in those chairs into a nearby inflatable medical tent uh to get out of their soal launch and entry suits into more comfortable flight clothing and then they'll be brought into uh towards uh individual helicopters in which they'll be flown two hours back to the staging city of karaganda Dyson will board a NASA plane that is waiting at the caranda airport uh for her trip back to the Johnson Space Center the two cosmonauts will board a gagaran Cosa Training Center aircraft for a flight back to their homes at their training base in Star City Russia outside of Moscow we are standing by for U video from inside the prall module uh that uh will show the departing crew members saying farewell to their space station colleagues uh they will float into the soyu vehicle which as I as I mentioned a few minutes ago has been placed on autonomous power the hatch uh uh to prall and there's our view inside the cramped quarters of the pasal module as you see Ali kenko the so commander in the green shirt on the right is NASA astronaut Mike Barrett Tracy Dyson a bidding farewell to Ivon Vagner that you see in the red shirt as uh kenko in company there's Nikolai Chu right behind kenko the uh departing crew saying farewell to the space station crew that remains on board the International Space Station once uh kenko Chu and Dyson uh move into the soyu vehicle the hatch to the pral module will be closed and then a few minutes later the hatch to the soou vehicle will be closed you can see in the red shirt by the hatchway is Alexi of chinin who launched uh 12 days ago along with Don Pettit and Ivon Vagner on the soyu ms26 spacecraft from the bike in Oran Drome in Kazakhstan Tracy Dyson launched back in March her return uh on Monday morning uh will wrap up her third flight into space and will give her an aggregate total of 373 days in space on her three space flights in the blue shirt uh in the foreground is uh cosmina uh Alexander Gren part of the crew 8 crew that will be returning to Earth on a SpaceX Dragon spacecraft in early October and there the three departing crew members have now left uh the International Space Station pral module they are inside soyu waving goodbye as they uh will make final preparations once the hatches are closed uh the crew will perform a series of uh initial leak checks at the docking interface between the soyu and the pasal module before they will Dawn their soal launch and entry suits the uh three departing crew members uh will be in The Descent module the center Center section of the three section soyu vehicle kin Yenko is the soyuz commander will be in the center seat flanked on his left by Nikolai chub who is board engineer number one for the entry and Landing operations Tracy Dyson will be on Keno's right as board engineer number two the uh space flight meteorology group here at the Johnson Space Center has issued a forecast for landing which again in Kazakhstan will be about an hour and 13 minutes before sunset on Monday the uh initial forecast uh calls for scattered clouds at 8,000 ft 28,000 ft Gusty winds but temperatures around 73° so the hatch to the soyu now closed at 12:02 a.

m. and now the hatch to the prall module being closed so we have hatch closure at 12:02 a. m. Central Time 10:2 a. m.

eastern time on Monday morning with the closing of the hatches uh leak checks will get underway a short time from now the crew will then Dawn their soal launch and entry suits and begin a series of communications checks with the Russian flight control team at the Russian Mission Control Center in kof on the outskirts of Moscow e you can see at at the hatchway is Alexi o chinin along with Ivan Vagner station space round one for Alexi the International Space Station moving from Southwest to Northeast will cross the coast of Indonesia a short time from now this is a good view in the center of your screen of the soyu ms25 spacecraft to the P module that's the bulbus multi hatched node module that is linked to the NAA multipurpose laboratory module on the earth facing side of the International Space Station is closed do you see the Telemetry well we um still have about 20 minutes we still have time just uh to the right of that on the far right of your screen is the soyu ms26 spacecraft that is docked to the Ross V module also on the earth facing side of the station that is the vehicle that brought up NASA's Don Pettit and Ros Cosmos cosmonauts Alexi of chinin and Ivan Vagner just 12 days ago I think you can turn it here you can attach it to the little crow trap is the stick here yes it's here what do you want oh I was just with Dyson kenko and Chu now inside the soyu ms25 spacecraft they will continue to make preparations for the undocking that is scheduled about 3 hours and 29 minutes from now the undocking command that enables the hooks to open between the soyu spacecraft and the prall docking port will be issued at 3:35 a. m. Central Time it takes about 90 seconds for those hooks to open Springs on both sides of the docking interface will push off against one another allowing the soyou to begin its departure from the International Space Station the soyu will move to a point well away from the station for the deorbit burn that will be a breaking maneuver a retrograde maneuver of 4 minutes and 39 seconds in duration allowing the so to drop out of orbit for its high-speed entry back into the Earth's atmosphere pyrot Technics will then allow the three sections of the soy use to separate from one another the crew of course inside the center section The Descent module that module separation scheduled at 6:33 a. m. Central Time the soyers will move into the uh atmosphere and then is as it approaches The Landing site a drug shoot will be deployed the command to open the shoots will be issued at 6:44 and 55 seconds a.

m. Central Time the drog shoot then pulls out the main shoot of the soyou it takes 15 minutes from that point until the soy lands but not before one final burst of the soft Landing engines uh to soften and cushion uh the landing on the step of Kazakhstan with landing schedule at 6:59 a. m. Central Time 7:59 a. m.

eastern time 459 p. m. at the Landing site about 91 miles to the southeast of the town of jez kazgan the search and Recovery forces called Ros aviaa along with the NASA support team they are are on route to jez kazgan from the staging City in caranda on a Russian antinoff military aircraft that antinoff will also serve as a uh command and relay station to relay data and voice from the soy crew back to the Russian flight control team in Coro outside of Moscow as the soyuz approaches The Landing site the um search and Recovery forces and the embedded NASA team will arrive at the JZ kazgan airport a couple of hours from now uh they'll pause in their work for a short period of time before they board helicopters with rotors spinning they'll be airborne wheels up from JZ kazgan right around the time of the deorbit burn heading for the landing site uh where they uh will watch the soyu's approach under its main shoot again touchdown schedule on Monday morning at 6:59 a. m. Central time 7:59 a.

m. eastern time 234 um R and yes you talking about for and4 yes we have it it's great and you also so with Tracy Dyson Al kononenko and Nikolai Chu inside the soyu ms25 that you see at the very top of your screen they will be starting uh the work to conduct leak checks at both sides of the docking interface between the the soyu and the prall docking port and then we'll Dawn their soal launch and entry suits and climb into their respective seats in The Descent module the center section of the so vehicle so that'll wrap up our uh hatch closure broadcast for this morning and we will point you to uh the resumption of coverage of soyu's Ms 25's return to Earth at 38 amm Central Time 4:00 a. m. eastern time just a few hours from now as the soyuz departs the International Space Station at the time of undocking expedition 71 will come to an end Expedition 72 will formally begin so join us back here in a couple of hours or so for undocking coverage in the meantime this is Mission Control Houston e
