62-555: Soyuz MS-09 was a Soyuz spaceflight that launched on 6 June 2018. It transported three members of the Expedition 56 / 57 crew to the International Space Station (ISS). MS-09 is the 138th flight of a Soyuz spacecraft. The crew consisted of a Russian commander along with an American and a German flight engineer. The mission ended at 05:02 UTC on 20 December 2018. During the night of 29 August 2018,
124-533: A barely angled (seven degrees) conical section to a classic spherical section heat shield. This shape allows a small amount of lift to be generated due to the unequal weight distribution. The nickname was thought up at a time when nearly every headlight was circular. The small dimensions of the descent module led to it having only two-man crews after the death of the Soyuz ;11 crew. The later Soyuz-T spacecraft solved this issue. Internal volume of Soyuz SA
186-499: A booster malfunction occurred. Based on data from R-7 launches over the years, engineers developed a list of the most likely failure modes for the vehicle and could narrow down abort conditions to premature separation of a strap-on booster, low engine thrust, loss of combustion-chamber pressure, or loss of booster guidance. The spacecraft abort system (SAS; Russian : Система Аварийного Спасения , romanized : Sistema Avarijnogo Spaseniya ) could also be manually activated from

There have been three failed launches of a crewed Soyuz vehicle: Soyuz 18a in 1975, Soyuz T-10a in 1983 and Soyuz MS-10 in October 2018. The 1975 failure was aborted after escape-tower jettison. In 1983, Soyuz T-10a's SAS successfully rescued the cosmonauts from an on-pad fire and explosion of the launch vehicle. Most recently, in 2018,
310-406: A later spacecraft, a capability which Soyuz does not possess, since the only hatch between the orbital and reentry modules is a part of the reentry module, and orbital module is depressurized after separation. For future missions, the orbital module(s) could also be left behind on the planned Chinese project 921/2 space station as additional station modules. In the uncrewed test flights launched,
372-402: A new theory being promoted by state media: that the hole is “due to suffering [psychologically] after a failed romantic relationship with one of the crew members.” Soyuz (spacecraft) Soyuz (Russian: Союз , IPA: [sɐˈjus] , lit. 'Union') is a series of spacecraft which has been in service since the 1960s, having made more than 140 flights. It was designed for
434-464: A revised Igla rendezvous system and new translation/attitude thruster system on the Service module. It could carry a crew of three, now wearing spacesuits. The Soyuz-TM crew transports (M: Russian : модифицированный , romanized : modifitsirovannyi , lit. 'modified') were fourth generation Soyuz spacecraft, and were used from 1986 to 2002 for ferry flights to Mir and
496-531: A small air leak in the ISS was noticed by ground control. A 2 mm (0.079 in) hole in the orbital module was discovered, later stated to have been "hidden with a low-quality patch job." Russian crew members used Kapton tape to temporarily seal the leak while a permanent fix was devised. The leak was successfully sealed with the use of a repair kit based on an epoxy sealant, and no further changes in air pressure were noted as of 31 August. On 4 September 2018, it

On later Soyuz versions (since Soyuz TM), a small window was introduced, providing the crew with a forward view. A hatch between it and the descent module can be closed so as to isolate it to act as an airlock if needed so that crew members could also exit through its side port (near

The literal meaning of the native name 神舟 ( p : Shénzhōu; / ˈ ʃ ɛ n ˈ dʒ oʊ / ) is "the Divine vessel [on the Heavenly River]", to which Heavenly River ( 天河 ) means the Milky Way in Classical Chinese . 神舟 is a pun and neologism that plays on the poetic word referring to China , 神州 , meaning Divine realm , which bears
682-524: A two-man craft Soyuz 7K would rendezvous with other components (9K and 11K) in Earth orbit to assemble a lunar excursion vehicle, the components being delivered by the proven R-7 rocket . The crewed Soyuz spacecraft can be classified into design generations. Soyuz 1 through Soyuz 11 (1967–1971) were first-generation vehicles, carrying a crew of up to three without spacesuits and distinguished from those following by their bent solar panels and their use of

The thermal protection system on the slightly conical side walls is stood off from the structure to also provide micrometeoroid protection in orbit. The slightly curved heat shield on the bottom consists of "21mm to 28mm thick ablator (glass-phenolic composite) which is held by brackets approximately 15mm from
806-436: Is a Chinese spacecraft developed for the nation's crewed space program . Its design was based on Russia's Soyuz , but larger and modernized, Shenzhou is a single-use vehicle composed of three modules. The descent module houses the crew during launch and reentry. The orbital module provides additional living space and storage during orbit but is jettisoned before reentry. The service module, responsible for propulsion and power,
868-529: Is a compromise between maximizing living space and allowing for some aerodynamic control upon reentry. The aft service module ( Chinese : 推进舱) ; pinyin : Tuījìn cāng ) contains life support and other equipment required for the functioning of Shenzhou. Two pairs of solar panels , one pair on the service module and the other pair on the orbital module, have a total area of over 40 square metres (430 sq ft), indicating average electrical power over 1.5 kW ( Soyuz have 1.0 kW). Although
930-448: Is a part of the reentry module, and the orbital module therefore depressurizes after separation. Reentry firing is usually done on the "dawn" side of the Earth, so that the spacecraft can be seen by recovery helicopters as it descends in the evening twilight, illuminated by the Sun when it is above the shadow of the Earth. The Soyuz craft is designed to come down on land, usually somewhere in
992-463: Is a sphere – as the pioneering Vostok spacecraft's descent module used – but such a shape can provide no lift, resulting in a purely ballistic reentry . Ballistic reentries are hard on the occupants due to high deceleration and cannot be steered beyond their initial deorbit burn. Thus it was decided to go with the "headlight" shape that the Soyuz uses – a hemispherical upper area joined by
1054-404: Is also discarded prior to reentry. For added safety and aerodynamics, the spacecraft is encased within a fairing with a launch escape system during liftoff. Its maiden uncrewed flight, Shenzhou 1 , was on 19 November 1999, with the first crewed mission, Shenzhou 5 , taking flight on 15 October 2003. It is slated for replacement by the next-generation Mengzhou , currently in development, with
1116-411: Is also the first expendable vehicle to feature a digital control technology. Soyuz-TMA looks identical to a Soyuz-TM spacecraft on the outside, but interior differences allow it to accommodate taller occupants with new adjustable crew couches. The Soyuz TMA-M was an upgrade of the baseline Soyuz-TMA, using a new computer, digital interior displays, updated docking equipment, and the vehicle's total mass
1178-578: Is based on the principle of minimizing the amount of material to be returned to Earth. Anything placed in the orbital or service modules does not require heat shielding , increasing the space available in the spacecraft without increasing weight as much as it would if those modules were also able to withstand reentry . The orbital module ( Chinese : 轨道舱) ; pinyin : Guǐdào cāng ) contains space for experiments, crew-serviced or crew-operated equipment, and in-orbit habitation. Without docking systems, Shenzhou 1–6 carried different kinds of payload on
1240-428: Is not reusable, a new Soyuz spacecraft must be made for every mission. Soyuz can carry up to three crew members and provide life support for about 30 person-days . A payload fairing protects Soyuz during launch and is jettisoned early in flight. Equipped with an automated docking system, the spacecraft can operate autonomously or under manual control. The Vostok spacecraft used an ejector seat to bail out
1302-439: Is slowed initially by the atmosphere, then by a braking parachute, followed by the main parachute, which slows the craft for landing. At one meter above the ground, solid-fuel braking engines mounted behind the heat shield are fired to give a soft landing. One of the design requirements for the descent module was for it to have the highest possible volumetric efficiency (internal volume divided by hull area). The best shape for this

#17327984446701364-578: Is where cosmonauts are seated for launch and reentry. The orbital module provides additional living space and storage during orbit but is jettisoned before reentry. The service module, responsible for propulsion and power, is also discarded prior to reentry. For added safety and aerodynamics, the spacecraft is encased within a fairing with a launch escape system during liftoff. The first Soyuz mission, Kosmos 133 , launched unmanned on 28 November 1966. The first crewed Soyuz mission, Soyuz 1 , launched on 23 April 1967 but ended tragically on 24 April 1967 when
1426-607: The Igla automatic docking navigation system, which required special radar antennas. This first generation encompassed the original Soyuz 7K-OK and the Soyuz 7K-OKS for docking with the Salyut 1 space station. The probe and drogue docking system permitted internal transfer of cosmonauts from the Soyuz to the station. The Soyuz 7K-L1 was designed to launch a crew from the Earth to circle
1488-412: The International Space Station (ISS). Soyuz TMA (A: Russian : антропометрический , romanized : antropometricheskii , lit. ' anthropometric ') features several changes to accommodate requirements requested by NASA in order to service the International Space Station (ISS), including more latitude in the height and weight of the crew and improved parachute systems. It
1550-698: The Kármán line , the conventional definition of the edge of space. Despite these early tragedies, Soyuz has earned a reputation as one of the safest and most cost-effective human spaceflight vehicles, a legacy built upon its unparalleled operational history. The spacecraft has served as the primary mode of transport for cosmonauts to and from the Salyut space stations , the Mir space station, and International Space Station (ISS). Soyuz spacecraft are composed of three primary sections (from top to bottom, when standing on
1612-536: The Moon , and was the primary hope for a Soviet circumlunar flight. It had several test flights in the Zond program from 1967–1970 ( Zond 4 to Zond 8 ), which produced multiple failures in the 7K-L1's reentry systems. The remaining 7K-L1s were scrapped. The Soyuz 7K-L3 was designed and developed in parallel to the Soyuz 7K-L1, but was also scrapped. Soyuz 1 was plagued with technical issues, and cosmonaut Vladimir Komarov
1674-578: The Shenzhou 5 mission. The spacecraft has since become the mainstay of the Chinese crewed space program , being used for both crewed and uncrewed missions . Shenzhou consists of three modules: a forward orbital module ( Chinese : 轨道舱) ; pinyin : Guǐdào cāng ), a reentry module ( Chinese : 返回舱) ; pinyin : Fǎnhuí cāng ) in the middle, and an aft service module ( Chinese : 推进舱) ; pinyin : Tuījìn cāng ). This division

It is launched atop the similarly named Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan . Following the Soviet Union's dissolution, Roscosmos , the Russian space agency, continued to develop and utilize

At the back of the vehicle is the service module (Russian: прибо́рно-агрега́тный отсе́к , romanized : pribórno-agregátny otsék ). It has a pressurized container shaped like a bulging can (instrumentation compartment, priborniy otsek ) that contains systems for temperature control, electric power supply, long-range radio communications , radio telemetry , and instruments for orientation and control. A non-pressurized part of
1860-550: The SAS sub-system in the payload shroud of Soyuz MS-10 successfully rescued the cosmonauts from a rocket failure 2 minutes and 45 seconds after liftoff, after the escape tower had already been jettisoned. The forepart of the spacecraft is the orbital module (Russian: бытовой отсек , romanized: bytovoi otsek ), also known as habitation section. It houses all the equipment that will not be needed for reentry, such as experiments, cameras or cargo. The module also contains
1922-408: The SAS were carried out in 1966–1967. The basic design of the SAS has remained almost unchanged in 50 years of use, and all Soyuz launches carry it. The only modification was in 1972, when the aerodynamic fairing over the SAS motor nozzles was removed for weight-saving reasons, as the redesigned Soyuz 7K-T spacecraft carried extra life-support equipment. The uncrewed Progress resupply ferry has

1984-534: The Shenzhou spacecraft follows the same layout as the Russian Soyuz spacecraft, it is approximately 10% larger and heavier than Soyuz. It also has a bigger cylindrical orbital module and four propulsion engines. There is enough room to carry an inflatable raft in case of a splashdown , whereas Soyuz cosmonauts must jump into the water and swim. The commander sits in the center seat on both spacecraft. However,
2046-776: The Soyuz spacecraft. Its maiden flight was in July 2016 with mission Soyuz MS-01 . Major changes include: The uncrewed Progress spacecraft are derived from Soyuz and are used for servicing space stations. While not being direct derivatives of Soyuz, the Chinese Shenzhou spacecraft uses Soyuz TM technology sold in 1984 and the Indian Orbital Vehicle follows the same general layout as that pioneered by Soyuz.

2108-652: The Soyuz. Between the Space Shuttle's 2011 retirement and the SpaceX Crew Dragon 's 2020 debut, Soyuz was the sole means of crewed transportation to and from the International Space Station, a role it continues to fulfill. The Soyuz design has also influenced other spacecraft, including China's Shenzhou and Russia's Progress cargo vehicle. The Soyuz is a single-use spacecraft composed of three main sections. The descent module
2170-497: The capability of the main parachute and braking engines to provide a safe soft-landing speed. In view of this, the orbital module was separated before the ignition of the return engine until the late 1980s. This guaranteed that the descent module and orbital module would be separated before the descent module was placed in a reentry trajectory. However, after the problematic landing of Soyuz TM-5 in September 1988 this procedure
2232-466: The connection between the service and reentry modules on the latter two flights. The Soyuz uses a method similar to the 1970s-era United States Apollo command and service module to deorbit itself. The spacecraft is turned engine-forward, and the main engine is fired for deorbiting on the far side of Earth ahead of its planned landing site. This requires the least propellant for reentry ; the spacecraft travels on an elliptical Hohmann transfer orbit to
2294-511: The cosmonaut in the event of a low-altitude launch failure, as well as during reentry; however, it would probably have been ineffective in the first 20 seconds after liftoff, when the altitude would be too low for the parachute to deploy. Inspired by the Mercury LES, Soviet designers began work on a similar system in 1962. This included developing a complex sensing system to monitor various launch-vehicle parameters and trigger an abort if
2356-417: The descent module). On the launch pad, the crew enter the spacecraft through this port. This separation also lets the orbital module be customized to the mission with less risk to the life-critical descent module. The convention of orientation in a micro-g environment differs from that of the descent module, as crew members stand or sit with their heads to the docking port. Also the rescue of the crew whilst on
2418-584: The deserts of Kazakhstan in Central Asia. This is in contrast to the early United States crewed spacecraft and the current SpaceX Crew Dragon, which splash down in the ocean. The Soyuz spacecraft has been the subject of continuous evolution since the early 1960s. Thus several different versions, proposals and projects exist. Sergei Korolev initially promoted the Soyuz A-B-V circumlunar complex ( 7K-9K-11K ) concept (also known as L1 ) in which
2480-411: The entry interface point, where atmospheric drag slows it enough to fall out of orbit. Early Soyuz spacecraft would then have the service and orbital modules detach simultaneously from the descent module. As they are connected by tubing and electrical cables to the descent module, this would aid in their separation and avoid having the descent module alter its orientation. Later Soyuz spacecraft detached
2542-539: The external hull, take images of the area and retrieve samples of residue to be used in the investigation. As the hole is in the orbital module that is jettisoned before re-entry, the return flight was not endangered. The return of the MS-09 crew was briefly delayed by the launch failure of Soyuz MS-10 (until the arrival of the next crew on MS-11 ). MS-09 landed on 20 December at about 05:03 UTC. Further reports and investigations were enacted thereafter. Prokopyev

2604-401: The facilities in it, including the toilet, following a failed deorbit. The descent module (Russian: Спуска́емый Аппара́т , romanized : spuskáyemy apparát ), also known as a reentry capsule, is used for launch and the journey back to Earth. Half of the descent module is covered by a heat-resistant covering to protect it during reentry ; this half faces forward during reentry. It

Since it turned out to be almost impossible to separate the entire payload shroud from the Soyuz service module cleanly, the decision was made to have the shroud split between the service module and descent module during an abort. Four folding stabilizers were added to improve aerodynamic stability during ascent. Two test runs of

The full treatment was published in 2020, documented in the correspondence paper "Venous Thrombosis during Spaceflight" by NEJM. The results of a Roscosmos investigation were later handed over to “law enforcement authorities” in late 2021, with
2790-403: The launch pad or with the SAS system is complicated because of the orbital module. Separation of the orbital module is critical for a safe landing; without separation of the orbital module, it is not possible for the crew to survive landing in the descent module. This is because the orbital module would interfere with proper deployment of the descent module's parachutes, and the extra mass exceeds
2852-440: The launch pad): The orbital and service modules are discarded and destroyed upon reentry . This design choice, while seemingly wasteful, reduces the spacecraft's weight by minimizing the amount of heat shielding required. As a result, Soyuz offers more habitable interior space (7.5 cubic metres, 260 cubic feet) compared to its Apollo counterpart (6.3 m , 220 cu ft). While the reentry module does return to Earth, it
2914-419: The orbital module before firing the main engine, which saved propellant. Since the Soyuz TM-5 landing issue, the orbital module is once again detached only after the reentry firing, which led to (but did not cause) emergency situations of Soyuz TMA-10 and TMA-11 . The orbital module cannot remain in orbit as an addition to a space station, as the airlock hatch between the orbital and reentry modules
2976-445: The orbital module of each Shenzhou was left functioning on orbit for several days after the reentry modules return, and the Shenzhou 5 orbital module continued to operate for six months after launch. The reentry module ( Chinese : 返回舱) ; pinyin : Fǎnhuí cāng ) is located in the middle section of the spacecraft and contains seating for the crew. It is the only portion of Shenzhou which returns to Earth's surface. Its shape
3038-418: The parachute failed to deploy on reentry, killing cosmonaut Vladimir Komarov . The following flight, Soyuz 2 was uncrewed. Soyuz 3 launched on 26 October 1968 and became the program's first successful crewed mission.The program suffered another fatal setback during Soyuz 11 , where cabin depressurization during reentry killed the entire crew. These are the only humans to date who are known to have died above

China's first efforts at human spaceflight started in 1968 with a projected launch date of 1973. Although China successfully launched an uncrewed satellite in 1970, its crewed spacecraft program was cancelled in 1980 due to a lack of funds. The Chinese crewed spacecraft program
3162-451: The sensors for the orientation system and the solar array, which is oriented towards the Sun by rotating the ship. An incomplete separation between the service and reentry modules led to emergency situations during Soyuz 5 , Soyuz TMA-10 and Soyuz TMA-11 , which led to an incorrect reentry orientation (crew ingress hatch first). The failure of several explosive bolts did not cut

It was developed out of the military Soyuz concepts studied in previous years and was capable of carrying 2 cosmonauts with Sokol space suits (after the Soyuz 11 accident). Several models were planned, but none actually flew in space. These versions were named Soyuz P , Soyuz PPK , Soyuz R , Soyuz 7K-VI , and Soyuz OIS (Orbital Research Station). The Soyuz 7K-T/A9 version

The Chinese spacecraft docking mechanism (beginning with Shenzhou 8) is based on the Androgynous Peripheral Attach System (APAS). Up until Shenzhou 8, the orbital module of the Shenzhou was equipped with its own propulsion , solar power , and control systems , allowing autonomous flight. It is possible for Shenzhou to leave an orbital module in orbit for redocking with

The first uncrewed flight of the spacecraft was launched on 19 November 1999, after which Project 921/1 was renamed Shenzhou , a name reportedly chosen by Jiang Zemin . A series of three additional uncrewed flights were carried out. The first crewed launch took place on 15 October 2003 with
3472-516: Was announced that the hole was created by a drill, but it was unclear if it was accidental or deliberate. Russian officials indicated the hole was some kind of sabotage, perhaps during the module's manufacturing process. Russian officials even speculated that one of the NASA crew members had drilled the hole. On 11 December 2018, Kononenko and Prokopyev conducted an EVA , cutting into the thermal blankets and pulling away insulation, in order to examine
3534-460: Was changed, and the orbital module is now separated after the return maneuver. This change was made as the TM-5 crew could not deorbit for 24 hours after they jettisoned their orbital module, which contained their sanitation facilities and the docking collar needed to attach to Mir . The risk of not being able to separate the orbital module is effectively judged to be less than the risk of needing

The next crewed version of the Soyuz was the Soyuz 7K-OKS . It was designed for space station flights and had a docking port that allowed internal transfer between spacecraft. The Soyuz 7K-OKS had two crewed flights, both in 1971. Soyuz 11 , the second flight, depressurized upon reentry, killing its three-man crew. The second generation, called Soyuz Ferry or Soyuz 7K-T , comprised Soyuz 12 through Soyuz 40 (1973–1981). It did not have solar arrays. Two long, skinny antennas were put in

In September 2019, the head of Roscosmos, Dmitry Rogozin , claimed that Roscosmos knows exactly what happened but that the agency would keep this information secret. On April 20, 2021, major Russian language tabloid Moskovskij Komsomolets published an article citing a Facebook post by Vadim Lukashevich which claimed that

The Soyuz TMA-08M mission set a new record for the fastest crewed docking with a space station. The mission used a new six-hour rendezvous, faster than the previous Soyuz launches, which had, since 1986, taken two days. Soyuz MS is the final planned upgrade of
