Voskhod 1 (Russian : Восход-1, lit. 'Sunrise-1') was the seventh crewed Soviet space flight. In October 1964 it achieved a number of "firsts" in the history of crewed spaceflight, being the first spaceflight to carry more than one crewman into orbit, the first flight without the use of spacesuits, and the first to carry either an engineer or a physician into outer space. It also set a crewed spacecraft altitude record of 336 km (209 mi).
The three spacesuits for the Voskhod 1 cosmonauts were omitted; there was neither the room nor the payload capacity for the Voskhod to carry them. The original Voskhod had been designed to carry two cosmonauts, but Soviet politicians pushed the Soviet space program into squeezing three cosmonauts into Voskhod 1. The only other space flight in the short Voskhod program, Voskhod 2, carried two suited cosmonauts – of necessity, because it was the flight on which Alexei Leonov made the world's first walk in space.
As part of its payload Voskhod 1 carried a ribbon off a Communard banner from the Paris Commune of 1871 into orbit.

The original prime crew of cosmonauts for Voskhod 1, composed of Boris Volynov, Georgi Katys, and Boris Yegorov, was rejected just three days before the scheduled launch date for the space capsule. Katys was reportedly removed after the KGB discovered that his father had been shot during the Great Purge in 1937 and Volynov apparently was the victim of discrimination due to his part-Jewish background, although he would later fly on Soyuz 5 and Soyuz 21.
Politics played a role in the crew's selection. Various factions each supported their own representatives for the flight. Sergei Korolev wanted his engineers to become cosmonauts, believing that spacecraft designers should fly in their own vehicles. The Soviet Air Force agreed to a crew composed of a military pilot, an engineer or scientist, and a doctor, but advocated for an all-military crew. Konstantin Feoktistov, who had been a design engineer for the Vostok, Voskhod, and Soyuz programs, was selected for this flight, becoming the only Soviet outer space designer to make a spaceflight. Yegorov, a medical doctor, used his political influence to get selected for the crew through his father's Politburo connections. The Soviet space program viewed its crews as passengers more than pilots; the new cosmonauts received only three to four months of training, perhaps the briefest in space history other than that received by the American politicians Jake Garn and Bill Nelson for Space Shuttle flights in the 1980s. : 413–414, 416

The Voskhod spacecraft were basically Vostok spacecraft with a backup solid-fuel retrorocket added onto the top of the descent module. The ejection seat was removed and three crew couches were added to the interior at a 90-degree angle to that of the Vostok cosmonaut's position. Because of the cramped conditions, the cosmonauts also had to go on a diet to fit in their couches. A solid-fuel braking rocket was also added to the space capsule's parachute lines to provide for a softer landing at touchdown. This was necessary because, unlike the Vostok space capsule, no ejection seats were fitted in the Voskhod; the cosmonauts had to land inside the descent module. [ citation needed ]Aside from that, the Vostok booster had lacked sufficient payload capacity to support the extra weight of a retrorocket package, but the larger upper stage used on the 11A57 launch vehicle meant that this was no longer an issue. As there was no launch escape system, the mission could not be aborted until three minutes after liftoff when the payload shroud was jettisoned and so a low-altitude booster accident would have meant the loss of the crew. As the cosmonauts rode the gantry elevator to the top of the launch vehicle, they could look across the steppe which was strewn with debris from previous failed R-7 launches, a grim reminder of what could potentially happen on their flight.
Liftoff took place at 7:30 on the morning of 12 October. For the first few minutes of the launch, the blockhouse was extremely tense knowing that the cosmonauts were doomed if any problem with the booster developed.[ citation needed ] Much of the mission of Voskhod 1 was devoted to biomedical research, and to the study of how a multidisciplinary team could work together in space. The mission was short, at only slightly over 24 hours. Incidentally, the Soviet premier Nikita Khrushchev was removed from power during the spaceflight, and it has been speculated that this led to the mission's being cut short. However, the cramped conditions of the Voskhod space capsule has also been suggested as a factor ruling out a longer-duration spaceflight.
During the flight, Khrushchev spoke with the cosmonauts via radio phone from his dacha in the Crimea. Shortly after this conversation, he was summoned back to Moscow where he learned that he was being expelled from office and the Communist Party. When the crew returned to Earth the next day, they were greeted by Leonid Brezhnev and Alexei Kosygin in their first public appearance as leaders of the Soviet Union.
Despite the propaganda boasting around Voskhod 1, it was privately referred to by the leadership of the Soviet space program as "a circus" due to the messy process of crew selection, the cosmonauts needing to diet to fit inside their spacecraft, Khrushchev's expulsion during the flight, and also the extremely dangerous circumstances of it (the crew having neither pressure suits nor any way to escape from a malfunctioning launch vehicle).
Happening as it did before the beginning of the Project Gemini two-man flights, Voskhod 1 had a significant, but temporary, international impact. The NASA Administrator, James E. Webb, called the flight of Voskhod 1 a "significant space accomplishment" adding that it was "a clear indication that the Russians are continuing a large space program for the achievement of national power and prestige."
The Voskhod 1 mission was the first three-man mission attempted by the USSR. The development for this mission was formally approved on 13 April 1964.This mission used a modified Vostok spacecraft that had been designed for previous manned missions. The modified Vostok spacecraft was renamed Voskhod 1 for the new three-man missions. The Voskhod 1 required many modifications since three cosmonauts had to fit in the capsule that had previously been designed for only one person. Some modifications also had to be made to the 11A57 launch vehicle which was used to launch the Voskhod 1. The first major modification was replacing the one ejection seat with three couches since there were now three cosmonauts. These couches included a suspension system to absorb the shock from launch and landing. Because of space and weight requirements these new seats could not be ejection seats. This resulted in a new parachute mechanism being needed to soft land the entire crew capsule. In addition, the limited space did not allow the cosmonauts to wear pressurized spacesuits and they were only able to wear training suits. This was not a major issue since the crew capsule was pressurized. However, it was less safe because the crew would not survive if the capsule depressurized while in space. In previous missions if the primary retrograde rocket failed the capsule would remain in orbit for 10 days before returning to earth. However, with a crew of three they would not be able to survive for that long. Because of this a backup retrograde rocket was added to deorbit the spacecraft in the event that the primary retrograde rocket failed. In addition to these modifications to Voskhod 1, the third stage of the 11A57 launch vehicle was also changed from the Block Ye to the more powerful Block I. This was done because all the modifications added nearly 600 kilograms of weight to Voskhod 1.
During the development of Voskhod 1 a test of the parachute system was conducted on 6 September 1964.The test was conducted by dropping a Voskhod capsule from an altitude of 10,000 meters. During the test, the hatch for the parachute failed to open. This resulted in the Voskhod capsule crashing without the parachute being deployed. After further testing of the parachute system, it was determined that the electrical circuit that controlled the parachute hatch was the cause of the failure. Because of this, the circuit was redesigned with redundancies of the main components. This resulted in a more reliable circuit. A second test of the Voskhod capsule took place on 5 October 1964. This test resulted in a successful soft landing under a parachute. An unmanned test flight was also conducted on 6 October 1964. For this test, a Voskhod spacecraft was renamed the Kosmos-47 and was put into orbit for one day. Kosmos-47 made a successful soft landing under the parachute. This was the last major test before the actual Voskhod 1 crewed mission. This development concluded with the successful Voskhod 1 mission which launched on 12 October 1964.
Vostok 1 was the first spaceflight of the Vostok programme and the first human spaceflight in history. The Vostok 3KA space capsule was launched from Baikonur Cosmodrome on April 12, 1961, with Soviet cosmonaut Yuri Gagarin aboard, making him the first human to cross into outer space.
Vladimir Mikhaylovich Komarov 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 Soviet 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.
The Space Race was a 20th-century competition between two Cold War adversaries, the Soviet Union (USSR) and the United States of America (USA), to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security, and became part of the symbolism and ideology of the time. The Space Race brought pioneering launches of artificial satellites, robotic space probes to the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and ultimately to the Moon.
Soyuz is a series of spacecraft which has been in service since the 1960s, having made more than 140 flights. It was designed for the Soviet space program by the Korolev Design Bureau. The Soyuz succeeded the Voskhod spacecraft and was originally built as part of the Soviet crewed lunar programs. It is launched on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan. Between the 2011 retirement of the Space Shuttle and the 2020 demo flight of SpaceX Crew Dragon, the Soyuz served as the only means to make crewed space flights and to reach the International Space Station, for which it remains heavily used.
PAO S. P. Korolev Rocket and Space Corporation Energia, also known as RSC Energia, is a Russian manufacturer of ballistic missile, spacecraft and space station components. The company is the prime developer and contractor of the Russian crewed spaceflight program; it also owns a majority of Sea Launch. Its name is derived from Sergei Korolev, the first chief of its design bureau, and the Russian word for energy.
Soyuz 5 was a Soyuz mission using the Soyuz 7K-OK spacecraft launched by the Soviet Union on 15 January 1969, which docked with Soyuz 4 in orbit. It was the first docking of two crewed spacecraft of any nation, and the first transfer of crew from one space vehicle to another of any nation, the only time a transfer was accomplished with a space walk – two months before the United States Apollo 9 mission performed the first internal crew transfer.
Vostok 6 was the first human spaceflight to carry a woman, cosmonaut Valentina Tereshkova, into space.
The Voskhod programme was the second Soviet human spaceflight project. Two one-day crewed missions were flown using the Voskhod spacecraft and rocket, one in 1964 and one in 1965, and two dogs flew on a 22-day mission in 1966.
Voskhod 2 was a Soviet crewed space mission in March 1965. The Vostok-based Voskhod 3KD spacecraft with two crew members on board, Pavel Belyayev and Alexei Leonov, was equipped with an inflatable airlock. It established another milestone in space exploration when Alexei Leonov became the first person to leave the spacecraft in a specialized spacesuit to conduct a 12-minute spacewalk.
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. As of July 2021, three countries and one private company (SpaceX) have launched humans to Earth orbit, and two private companies have launched humans on a suborbital trajectory. The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale defines spaceflight as any flight over 100 kilometers (62 mi). In the United States professional, military, and commercial astronauts who travel above an altitude of 80 kilometers (50 mi) are awarded the United States Astronaut Badge. This article follows the FAI definition of spaceflight.
The Vostok was a type of spacecraft built by the Soviet Union. The first human spaceflight was accomplished with Vostok 1 on April 12, 1961, by Soviet cosmonaut Yuri Gagarin.
The Vostok programme was a Soviet human spaceflight project to put the first Soviet citizens into low Earth orbit and return them safely. Competing with the United States Project Mercury, it succeeded in placing the first human into space, Yuri Gagarin, in a single orbit in Vostok 1 on April 12, 1961. The Vostok capsule was developed from the Zenit spy satellite project, and its launch vehicle was adapted from the existing R-7 Semyorka intercontinental ballistic missile (ICBM) design. The name "Vostok" was treated as classified information until Gagarin's flight was first publicly disclosed to the world press.
The Voskhod was a spacecraft built by the Soviet Union's space program for human spaceflight as part of the Voskhod programme. It was a development of and a follow-on to the Vostok spacecraft. Voskhod 1 was used for a three-man flight whereas Voskhod 2 had a crew of two. They consisted of a spherical descent module, which housed the cosmonauts, and instruments, and a conical equipment module, which contained propellant and the engine system. Voskhod was superseded by the Soyuz spacecraft in 1967.
The Soviet space program was the national space program of the Union of Soviet Socialist Republics (USSR), conducted in competition with its Cold War adversary the United States, known as the Space Race from the mid-1950s until the dissolution of the Soviet Union in 1991. It consisted of the development of expendable launch vehicles, uncrewed artificial satellites starting in 1953, and several human spaceflight programs.
A space capsule is an often-crewed spacecraft that uses a blunt-body reentry capsule to reenter the Earth's atmosphere without wings. Capsules are distinguished from satellites primarily by the ability to survive reentry and return a payload to the Earth's surface from orbit. Capsule-based crewed spacecraft such as Soyuz or Orion are often supported by a service or adapter module, and sometimes augmented with an extra module for extended space operations. Capsules make up the majority of crewed spacecraft designs, although one crewed spaceplane, the Space Shuttle, has flown in orbit.
A reentry capsule is the portion of a space capsule which returns to Earth following a spaceflight. The shape is determined partly by aerodynamics; a capsule is aerodynamically stable falling blunt end first, which allows only the blunt end to require a heat shield for atmospheric entry. A crewed capsule contains the spacecraft's instrument panel, limited storage space, and seats for crew members. Because a capsule shape has little aerodynamic lift, the final descent is via parachute, either coming to rest on land, at sea, or by active capture by an aircraft. In contrast, the development of spaceplane reentry vehicles attempts to provide a more flexible reentry profile.
Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth. First successful large-scale rocket programs were initiated in the 1920s Germany by Fritz von Opel and Max Valier, and eventually in Nazi Germany by Wernher von Braun. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first man and the first woman into orbit. The United States caught up with, and then passed, their Soviet rivals during the mid-1960s, landing the first man on the Moon in 1969. In the same period, France, the United Kingdom, Japan and China were concurrently developing more limited launch capabilities.
Zhanna Dmitriyevna Yorkina was a Soviet Cosmonaut.
Kosmos 47 is the designation of an uncrewed test flight of a prototype Soviet Voskhod spacecraft, the first multiple-occupant spacecraft. Launched on 6 October 1964, the successful flight paved the way for the first crewed mission, Voskhod 1, which occurred just 6 days later on 12 October 1964.
Vostok 3 and Vostok 4 were Soviet space program flights in August 1962, intended to determine the ability of the human body to function in conditions of weightlessness, test the ground control capability to launch and manage two separate, concurrent flights, and test the endurance of the Vostok 3KA spacecraft over longer flights. Cosmonaut Andriyan Nikolayev orbited the Earth 64 times in Vostok 3 over nearly four days in space, August 11–15, 1962, a feat which would not be matched by NASA until the Gemini program (1965–1966). Pavel Popovich was launched on Vostok 4 on August 12, and made 48 Earth orbits. The two capsules were launched on trajectories that brought the spacecraft within approximately 6.5 km (4.0 mi) of each another.
