Soyuz 1 (Russian: Союз 1, Union 1) was a manned spaceflight of the Soviet space program. Launched into orbit on 23 April 1967 carrying cosmonaut Colonel Vladimir Komarov, Soyuz 1 was the first crewed flight of the Soyuz spacecraft. The flight was plagued with technical issues, and Komarov was killed when the descent module crashed into the ground due to a parachute failure. This was the first in-flight fatality in the history of spaceflight.
The original mission plan was complex, involving a rendezvous with Soyuz 2 and an exchange of crew members before returning to Earth. However, the launch of Soyuz 2 was called off due to thunderstorms.

Second and last spaceflight
Soyuz 1 was the first manned flight of the first-generation Soyuz 7K-OK spacecraft and Soyuz rocket, designed as part of the Soviet lunar program. It was the first Soviet manned spaceflight in over two years, and the first Soviet manned flight following the death of the Chief Designer of the space program Sergei Korolev. Komarov was launched on Soyuz 1 despite failures of the previous unmanned tests of the 7K-OK, Cosmos 133 and Cosmos 140. A third attempted test flight was a launch failure; a launch abort triggered a malfunction of the launch escape system, causing the rocket to explode on the pad. The escape system successfully pulled the spacecraft to safety.
Prior to launch, Soyuz 1 engineers are said to have reported 203 design faults to party leaders, but their concerns "were overruled by political pressures for a series of space feats to mark the anniversary of Lenin's birthday." It is not clear how much of this pressure resulted from wanting to continue beating the United States in the Space Race and to have Soviets first on the Moon, or to take advantage of the recent setbacks in the U.S. space program with the Apollo 1 disaster.
Yuri Gagarin was the backup pilot for Soyuz 1, and was aware of the design problems and the pressures from the Politburo to proceed with the flight. He attempted to "bump" Komarov from the mission, knowing that the Soviet leadership would not risk a national hero on the flight. At the same time, Komarov refused to pass on the mission, even though he believed it to be doomed. He explained that he could not risk Gagarin's life.
Mission planners intended to launch a second Soyuz flight the next day carrying cosmonauts Valery Bykovsky, Yevgeny Khrunov, and Aleksei Yeliseyev, with Khrunov and Yeliseyev scheduled to do an EVA over to Soyuz 1.
Soyuz 1 was launched on 23 April 1967 at 00:32 UTC from Baikonur Cosmodrome carrying Komarov, the first Soviet cosmonaut to fly in space twice.
Problems began shortly after launch when one solar panel failed to unfold, leading to a shortage of power for the spacecraft's systems. Further problems with the orientation detectors complicated maneuvering the craft. By orbit 13, the automatic stabilization system was completely dead, and the manual system was only partially effective.
The crew of Soyuz 2 modified their mission goals, preparing themselves for a launch that would include fixing the solar panel of Soyuz 1. However, that night, thunderstorms at Baikonur Cosmodrome in Kazakhstan affected the booster's electrical system, causing the mission to be called off.
As a result of Komarov's report during the 13th orbit, the flight director decided to abort the mission. After 18 orbits, Soyuz 1 fired its retrorockets and reentered the Earth's atmosphere. Despite the technical difficulties up to that point, Komarov might still have landed safely. To slow the descent, first the drogue parachute was deployed, followed by the main parachute. However, due to a defect, the main parachute did not unfold; the exact reason for the main parachute malfunction is disputed.
Komarov then activated the manually deployed reserve chute, but it became tangled with the drogue chute, which did not release as intended. As a result, the Soyuz reentry module fell to Earth in Orenburg Oblast almost entirely unimpeded, at about 40 m/s (140 km/h; 89 mph). A rescue helicopter spotted the descent module lying on its side with the parachute spread across the ground. The retrorockets then started firing which concerned the rescuers since they were supposed to activate a few moments prior to touchdown. By the time they landed and approached, the descent module was in flames with black smoke filling the air and streams of molten metal dripping from the exterior. The entire base of the capsule burned through. By this point, it was obvious that Komarov had not survived, but there was no code signal for a cosmonaut's death, so the rescuers fired a signal flare calling for medical assistance. Another group of rescuers in an aircraft then arrived and attempted to extinguish the blazing spacecraft with portable fire extinguishers. This proved insufficient and they instead began using shovels to throw dirt onto it. The descent module then completely disintegrated, leaving only a pile of debris topped by the entry hatch. When the fire at last ended, the rescuers were able to dig through the rubble to find Komarov's remains strapped into the center couch. Doctors pronounced the cause of death to be from multiple blunt-force injuries.
The body was transported to Moscow for an official autopsy in a military hospital where the cause of death was verified to match the field doctors' conclusions.
Eight years after Komarov's death, a story began circulating that Komarov cursed the engineers and flight staff, and spoke to his wife as he descended, and these transmissions were received by an NSA listening station near Istanbul. Historians regard this to be untrue.
The Soyuz 1 tragedy delayed the launch of Soyuz 2 and Soyuz 3 until 25 October 1968. This eighteen-month gap, with the addition of the explosion of an unmanned N-1 rocket on July 3, 1969, scuttled Soviet plans of landing a cosmonaut on the Moon. The original mission of Soyuz 1 and Soyuz 2 was ultimately completed by Soyuz 4 and Soyuz 5.
A much improved Soyuz program emerged from this eighteen-month delay, mirroring the improvements made in Project Apollo after the Apollo 1 tragedy. Although it failed to reach the Moon, the Soyuz went on to be repurposed from the centerpiece of the Zond lunar program to the people-carrier of the Salyut space station program, the Mir space station, and the International Space Station. Although it suffered another tragedy with the Soyuz 11 accident in 1971, and went through several incidents with non-fatal launch aborts and landing mishaps, it has become one of the longest-lived and most dependable manned spacecraft yet designed.
The year 1967 in science and technology involved some significant events, listed below.Kosmos 140
Kosmos 140 (Russian: Космос 140 meaning Cosmos 140) was an unmanned flight of the Soyuz spacecraft. It was the third attempted test flight of the Soyuz 7K-OK model, after orbital (Kosmos 133) and launch (Soyuz 11A511) failures of the first two Soyuz spacecraft.The followup to Cosmos 133 was planned for 14 December, but ended disastrously. At liftoff, the Blok A core stage of the 11A57 booster ignited, but not the strap-ons. A shutdown command was immediately sent and pad crews began to move the service towers back in place and drain the propellants. This task was completed for the core stage and strap-ons, and then about 30 minutes after the attempted launch, the escape tower suddenly fired. Its exhaust caused the Blok I third stage propellant tanks to overheat and explode, killing one person on the ground and damaging the Soyuz and core stage/strap-ons beyond repair. LC-1 was also badly damaged and took a month of repair work in the frigid Kazakhstan winter to be restored to use. The reason for the LES firing was thought to be either a timer being activated due to the Earth's rotation affecting the gyroscope package in the launch vehicle or perhaps one of the service towers bumping it.
In February 1967, the backup booster and spacecraft were set up at LC-1 and the planned mission could be carried out.
The spacecraft suffered attitude control problems and excessive fuel consumption in orbit, but remained controllable. An attempted maneuver on the 22nd orbit still showed problems with the control system. It malfunctioned yet again during retrofire, leading to a steeper than planned ballistic reentry and a 300 mm (12 in) hole being burned in the heat shield.Although the event would have been lethal to any human occupants, the capsule's recovery systems operated and the capsule crashed through the ice of the frozen Aral Sea, hundreds of kilometers short of its landing zone. The spacecraft finally sank in 10 meters of water and had to be retrieved by divers. The test performance was nonetheless deemed "good enough"; the manned docking missions of Soyuz 1 and Soyuz 2 were approved for the next flight.Kosmos 238
Kosmos 238 (Russian: Космос 238 meaning Cosmos 238) was the final test series of the Soviet Soyuz spacecraft prior to the launch of Soyuz 3. It tested the orbital maneuvering system, reentry, descent and landing systems that had been modified and improved after the Soyuz 1 accident.List of Soyuz missions
This is a list of crewed and uncrewed flights of Soyuz series spacecraft.
The Soyuz programme is an ongoing human spaceflight programme which was initiated by the Soviet Union in the early 1960s, originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon. It is the third Soviet human spaceflight programme after the Vostok and Voskhod programmes. Since the 1990s, as the successor state to the Soviet Union, Russia has continued and expanded the programme, which became part of a multinational collaboration to ensure a permanent human presence in low Earth orbit on the International Space Station (ISS). Since the retirement of the Space Shuttle in 2011, Soyuz spacecraft are the exclusive vessels ferrying astronauts to and from the ISS.List of human spaceflights
This is a list of all human spaceflights throughout history. Beginning in 1961 with the flight of Yuri Gagarin aboard Vostok 1, human spaceflight occurs when a human crew flies a spacecraft into outer space. Human spaceflight is distinguished from spaceflight generally, which entails both crewed and uncrewed spacecraft.
There are two definitions of spaceflight. The Fédération Aéronautique Internationale (FAI), an international record-keeping body, defines the boundary between Earth's atmosphere and outer space at 100 kilometers above sea level. This boundary is known as the Kármán line. Additionally, the United States military awards astronaut wings to qualified personnel who pilot a spaceflight above an altitude of 50 miles (80 km). Thirteen flights of the North American X-15 met the latter criteria, while only two met the former. This article is primarily concerned with the former international convention, and also lists flights which only satisfied the latter convention. Unless otherwise specified, "spaceflight" and related terms only apply to flights which went beyond the Kármán line.
As of the launch of Soyuz MS-12 on 14 March 2019, there have been 325 human spaceflight launch attempts, including three failed attempts which did not cross the Kármán line. These were the fatal Challenger disaster, and two non-fatal aborted Soyuz missions, T-10a and MS-10. Another non-fatal aborted Soyuz mission, 18a, nevertheless crossed the Kármán line and therefore qualified as a sub-orbital spaceflight. Three missions successfully achieved human spaceflight, yet ended as fatal failures as their crews died during the return. These were Soyuz 1, Soyuz 11, and the Columbia disaster. Uniquely, Soyuz 34 was launched uncrewed to the Salyut 6 space station, to provide a successful return vehicle for the crew of Soyuz 32. Including Soyuz 34 gives a total of 326 attempted human spaceflights. 14 flights reached an apogee beyond 50 miles, but failed to go beyond 100 kilometers.NK-33
The NK-33 and NK-43 are rocket engines designed and built in the late 1960s and early 1970s by the Kuznetsov Design Bureau. The NK designation is derived from the initials of chief designer Nikolay Kuznetsov. The NK-33 was among the most powerful LOX/RP-1 rocket engines when it was built, with a high specific impulse and low structural mass. They were intended for the ill-fated Soviet N-1 rocket Moon shot. The NK-33A rocket engine is now used on the first stage of the Soyuz-2-1v launch vehicle.Soviet crewed lunar programs
The Soviet crewed lunar programs were a series of programmes pursued by the Soviet Union to land a man on the Moon, in competition with the United States Apollo program to achieve the same goal set publicly by President John F. Kennedy on May 25, 1961. The Soviet government publicly denied participating in such a competition, but secretly pursued two programs in the 1960s: crewed lunar flyby missions using Soyuz 7K-L1 (Zond) spacecraft launched with the Proton-K rocket, and a crewed lunar landing using Soyuz 7K-LOK and LK Lander spacecraft launched with the N1 rocket. Following the dual American successes of the first crewed lunar orbit on December 24–25, 1968 (Apollo 8) and the first Moon landing on July 20, 1969 (Apollo 11), and a series of catastrophic N1 failures, both Soviet programs were eventually brought to an end. The Proton-based Zond program was canceled in 1970, and the N1 / L3 program was de facto terminated in 1974 and officially canceled in 1976. Details of both Soviet programs were kept secret until 1990 when the government allowed them to be published under the policy of glasnost.Soviet ship Kosmonavt Vladimir Komarov
Kosmonavt Vladimir Komarov was a satellite tracking ship of the Soviet Union.
It was named after Vladimir Mikhaylovich Komarov, the cosmonaut who died on Soyuz 1.
It was built as an ordinary cargo ship in 1966 and converted in Leningrad in 1967.
It was decommissioned in 1989.Soviet space program
The Soviet space program (Russian: Космическая программа СССР, Kosmicheskaya programma SSSR) comprised several of the rocket and space exploration programs conducted by the Soviet Union (USSR) from the 1930s until its collapse in 1991. Over its 60-year history, this primarily classified military program was responsible for a number of pioneering accomplishments in space flight, including the first intercontinental ballistic missile (R-7), first satellite (Sputnik 1), first animal in Earth orbit (the dog Laika on Sputnik 2), first human in space and Earth orbit (cosmonaut Yuri Gagarin on Vostok 1), first woman in space and Earth orbit (cosmonaut Valentina Tereshkova on Vostok 6), first spacewalk (cosmonaut Alexei Leonov on Voskhod 2), first Moon impact (Luna 2), first image of the far side of the Moon (Luna 3) and unmanned lunar soft landing (Luna 9), first space rover (Lunokhod 1), first sample of lunar soil automatically extracted and brought to Earth (Luna 16), and first space station (Salyut 1). Further notable records included the first interplanetary probes: Venera 1 and Mars 1 to fly by Venus and Mars, respectively, Venera 3 and Mars 2 to impact the respective planet surface, and Venera 7 and Mars 3 to make soft landings on these planets.
The rocket and space program of the USSR, initially boosted by the assistance of captured scientists from the advanced German rocket program, was performed mainly by Soviet engineers and scientists after 1955, and was based on some unique Soviet and Imperial Russian theoretical developments, many derived by Konstantin Tsiolkovsky, sometimes known as the father of theoretical astronautics. Sergey Korolev (also transliterated as Korolyov) was the head of the principal design group; his official title was "chief designer" (a standard title for similar positions in the USSR). Unlike its American competitor in the "Space Race", which had NASA as a single coordinating agency, the USSR's program was split among several competing design bureaus led by Korolev, Mikhail Yangel, Valentin Glushko, and Vladimir Chelomei.
Because of the program's classified status, and for propaganda value, announcements of the outcomes of missions were delayed until success was certain, and failures were sometimes kept secret. Ultimately, as a result of Mikhail Gorbachev's policy of glasnost in the 1980s, many facts about the space program were declassified. Notable setbacks included the deaths of Korolev, Vladimir Komarov (in the Soyuz 1 crash), and Yuri Gagarin (on a routine fighter jet mission) between 1966 and 1968, and development failure of the huge N-1 rocket intended to power a manned lunar landing, which exploded shortly after lift-off on four unmanned tests.
With the collapse of the Soviet Union, Russia and Ukraine inherited the program. Russia created the Russian Aviation and Space Agency, now known as the Roscosmos State Corporation, while Ukraine created the National Space Agency of Ukraine (NSAU).Soyuz-1
Soyuz-1 may refer to:
Soyuz 1, the first manned flight of the Soyuz programme
Soyuz TM-31, the first Soyuz mission to the International Space Station
Soyuz-1 (rocket), a proposed Russian carrier rocketSoyuz-2-1v
The Soyuz-2-1v (Russian: Союз 2.1в, Union 2.1v), GRAU index 14A15, known earlier in development as the Soyuz-1 (Russian: Союз 1, Union 1), is a Russian expendable carrier rocket. It was derived from the Soyuz-2.1b, and is a member of the R-7 family of rockets. It is built by TsSKB Progress, at Samara in the Russian Federation. Launches are conducted from existing facilities at the Plesetsk Cosmodrome in Northwest Russia, with pads also available at the Baikonur Cosmodrome in Kazakhstan, and new facilities at the Vostochny Cosmodrome in Eastern Russia.Soyuz (spacecraft)
Soyuz (Russian: Сою́з, IPA: [sɐˈjus], lit. Union) is a series of spacecraft designed for the Soviet space program by the Korolev Design Bureau (now RKK Energia) in the 1960s that remains in service today. The Soyuz succeeded the Voskhod spacecraft and was originally built as part of the Soviet manned lunar programs. The Soyuz spacecraft is launched on a Soyuz rocket, the most reliable launch vehicle in the world to date. The Soyuz rocket design is based on the Vostok launcher, which in turn was based on the 8K74 or R-7A Semyorka, a Soviet intercontinental ballistic missile. All Soyuz spacecraft are launched from the Baikonur Cosmodrome in Kazakhstan. Soyuz is currently the only means for manned space flights in the world and is heavily used in the International Space Station program.Soyuz 2A
Soyuz 2A is the unofficial designation for a cancelled space flight of a Soyuz spacecraft, planned to rendezvous with the Soyuz 1 mission. The launch of the craft in April 1967 was cancelled due to poor weather conditions, likely saving the three-person crew from the same design problems that killed the one-person crew of Soyuz 1.
In the Soviet space program it was usual only for successful launches to gain official designations, so this mission did not receive an official designation and is informally named Soyuz 2A to distinguish it from the later official Soyuz 2 mission, which was launched in October 1968 as an unmanned docking target for Soyuz 3.Soyuz 3
Soyuz 3 ("Union 3", Russian: Союз 3) was a spaceflight mission launched by the Soviet Union on 26 October 1968. Flown by Georgy Beregovoy, the Soyuz 7K-OK spacecraft completed 81 orbits over four days. The 47-year-old Beregovoy was a decorated World War II flying ace and the oldest person to go into space up to that time. The mission achieved the first Russian space rendezvous with the unmanned Soyuz 2, but failed to achieve a planned docking of the two craft.Soyuz 7K-OK
Soyuz 7K-OK was the first generation of Soyuz spacecraft in use from 1967 to 1971.
This first generation was used for the first ferry flights to the Salyut space station program; Soyuz spacecraft in their current generation are still in use to ferry crew to and from the ISS.
This generation is notable for the only fatalities of the Soyuz programme As of 2019, with Soyuz 1 in 1967 (sole crew-member killed by parachute failure) and Soyuz 11 in 1971 (crew killed by depressurization during reentry).
The first unmanned automated docking in the history of spaceflight, between Kosmos 186 and Kosmos 188 in 1967, was achieved with this generation of Soyuz spacecraft. The generation encompasses furthermore the first docking between two manned spacecraft (Soyuz 4 and Soyuz 5), the longest manned flight involving only one spacecraft (the 18-day flight of Soyuz 9 in 1970) and the first successful manning of the first space station in the history of space flight (Soyuz 11 and Salyut 1 in 1971).
The Soyuz 7K-OK vehicles carried a crew of up to three without spacesuits. The craft can be distinguished from those following by their bent solar panels and their use of the Igla automatic docking navigation system, which required special radar antennas.
The 7K-OK was primarily intended as a variant of the 7K-LOK (the lunar mission Soyuz) for Earth orbital testing. Mostly the same vehicle, it lacked the larger antenna needed to communicate at lunar distance. The early Soyuz models also sported an external toroidal fuel tank surrounding the engines and meant to store extra propellant for lunar flights, but it was left empty on Soyuz 1-9. After the spacecraft was converted to a space station ferry, the tank was removed.
Soyuz 7K-OK spacecraft had a "probe and drogue" docking mechanism to connect with other spacecraft in orbit, in order to gather engineering data as a preparation for the Soviet space station program. There were two variants of Soyuz 7K-OK: Soyuz 7K-OK(A) featuring an active "probe" docking port, and Soyuz 7K-OK(P) featuring a passive "drogue" docking target. The docking mechanisms of 7K-OK and 7K-LOK did not allow internal transfer (this feature was added on the 7K-OKS version), thus cosmonauts had to spacewalk between docked modules. This procedure was conducted successfully on the joint Soyuz 4 and Soyuz 5 missions, where Aleksei Yeliseyev and Yevgeny Khrunov transferred from their Soyuz 5 to the Soyuz 4 craft.
The first unmanned test of this version was Kosmos 133, launched on November 28, 1966.Soyuz TMA-15
Soyuz TMA-15 was a manned spaceflight to the International Space Station. Part of the Soyuz programme, it transported three members of the Expedition 20 crew to the space station. TMA-15 was the 102nd manned flight of a Soyuz spacecraft, since Soyuz 1 in 1967. The Soyuz spacecraft remain docked to the space station during Expedition 20 and Expedition 21 as an emergency escape vehicle. The mission marked the start of six-person crew operations on the ISS.Valeri Kubasov
Valeri Nikolayevich Kubasov (Russian: Вале́рий Никола́евич Куба́сов; 7 January 1935 – 19 February 2014) was a Soviet/Russian cosmonaut who flew on two missions in the Soyuz programme as a flight engineer: Soyuz 6 and Soyuz 19 (the Apollo–Soyuz mission), and commanded Soyuz 36 in the Intercosmos programme. On 21 July 1975, the Soyuz 7K-TM module used for ASTP landed in Kazakhstan at 5:51 p.m. and Kubasov was the first to exit the craft. Kubasov performed the first welding experiments in space, along with Georgy Shonin.
Kubasov was also involved in the development of the Mir space station. He retired from the Russian space program in November 1993 and was later deputy director of RKK Energia.
Kubasov evaded death twice during his space career. He was part of the crew that was originally intended to fly Soyuz 2, which was found to have the same faulty parachute sensor that resulted in Vladimir Komarov's death on Soyuz 1 and was later launched without a crew. Later, he was grounded for medical reasons before the Soyuz 11 flight, which killed the crew when the capsule was accidentally depressurised by a faulty valve.Valery Bykovsky
Valery Fyodorovich Bykovsky (Russian: Вале́рий Фёдорович Быко́вский; 2 August 1934 – 27 March 2019) was a Soviet cosmonaut who flew on three space flights: Vostok 5, Soyuz 22, and Soyuz 31. He was also backup for Vostok 3 and Soyuz 37.Vladimir Komarov
Vladimir Mikhaylovich Komarov (Russian: Влади́мир Миха́йлович Комаро́в, IPA: [vlɐˈdʲimʲɪr mʲɪˈxaɪləvʲɪtɕ kəmɐˈrof]; 16 March 1927 – 24 April 1967) was a Soviet test pilot, aerospace engineer and cosmonaut. In October 1964, he commanded Voskhod 1, the first spaceflight to carry more than one crew member. He became the first cosmonaut to fly in space twice when he was selected as the solo pilot of Soyuz 1, its first crewed test flight. A parachute failure caused his Soyuz capsule to crash into the ground after re-entry on 24 April 1967, making him the first human to die in a space flight.Komarov was one of the most highly experienced and qualified candidates accepted into the first squad of cosmonauts selected in 1960. He was declared medically unfit for training or spaceflight twice while he was in the program, but his perseverance and superior skills, and his knowledge as an engineer, allowed him to continue playing an active role. During his time at the cosmonaut training center he contributed to space vehicle design, cosmonaut training and evaluation and public relations.
