Vostok programme
Encyclopedia
The Vostok programme was a Soviet
human spaceflight
project that succeeded in putting a person into Earth
's orbit for the first time. The programme developed the Vostok spacecraft
from the Zenit spy satellite
project and adapted the Vostok rocket
from an existing ICBM design. Just before the first release of the name Vostok to the press, it was a classified word.
There were six manned spaceflights in the Vostok programme, all of which took place between 1961 and 1963. The programme preceeded the Voskhod programme
, which used modified Vostok capsules. By the late 1960's, those programmes were superseded by the Soyuz programme
, which continues as of 2011.
, had been put into orbit by the Soviets in 1957. The next milestone in the history of space exploration would be to put a human in space, and both the Soviets and the Americans wanted to be the first.
By January 1959, the Soviets had begun preparations for human spaceflight. Physicians from the Soviet Air Force insisted that the potential cosmonaut candidates be qualified Air Force pilots, arguing that they would have relevant skills such as exposure to higher g-force
s, as well as ejection seat experience; also the Americans had chosen the Mercury Seven
in April 1959, all of whom had aviation backgrounds. The candidates had to be intelligent, comfortable in high-stress situations, and physically fit.
Chief designer of the Soviet space program, Sergei Korolev, decided that the cosmonauts must be male, between 25 and 30 years old, no taller than 1.75 meters, and weigh no more than 72 kilograms. The final specifications for cosmonauts were approved in June 1959. By September interviews with potential cosmonauts had begun. Although the pilots were not told they might be flying into space, one of the physicians in charge of the selection process believed that some pilots had figured this out. Just over 200 candidates made it through the interview process, and by October a series of demanding physical tests were conducted on those remaining, such as exposure to low pressures, and a centrifuge test
. By the end of 1959, 20 men had been selected. Korolev insisted on having a larger group than NASA's seven astronaut team. Of these 20, five were outside the desired age range; so the age requirement was relaxed. Unlike NASA's astronaut group, this group were not particularly experienced pilots; Belyayev was the most experience with 900 flying hours. The Soviet spacecraft were more automated than the American counterparts, so significant piloting experience was not necessary.
On January 11, 1960, Soviet Chief Marshal of Aviation
Konstantin Vershinin
approved plans to establish the Cosmonaut Training Center
, whose exclusive purpose would be to prepare the cosmonauts for their upcoming flights; initially the facility would have about 250 staff. Vershinin assigned the already famous aviator Nikolai Kamanin
to supervise operations at the facility. By March, most of the cosmonauts had arrived at the training facility; on March 7 Vershinin gave a welcome speech, and those who were present were formally inducted into the cosmonaut group. By mid-June all twenty were permanently stationed at the center. In March the cosmonauts were started on a daily fitness regime, and were taught classes on topics such as rocket space systems, navigation, geophysics, and astronomy.
Due to the initial facility's space limitations, the cosmonauts and staff were relocated to a new facility in Star City
(then known as Zelenyy), which has been the home of Russia's cosmonaut training program for over fifty years. The move officially took place on June 29, 1960.
, a spacecraft simulator had been built, and it was called the TDK-1. Due to the inefficiency of training all 20 cosmonauts in the simulator, it was decided they would select six men who would go through accelerated training. This group, which would be known as The Vanguard Six, was decided on May 30, 1960, and initially consisted of Gagarin, Kartashov, Nikolayev, Popovich, Titov, and Varlamov. Alexei Leonov recalls that these six were the shortest six out of the group of 20.
In July, shortly after relocation to Star City, two of the six would be replaced, on medical grounds. First, during a centrifuge test of 8 g's
, Kartashov experienced some internal damage, causing minor hemorrhaging
on his back. Despite Gagarin's requests for him to stay, the doctors decided to remove Kartashov from the group of six. Later in July, Varlamov was involved in a swimming accident. During a dive into a lake near the training center, he hit his head on the bottom, displacing a cervical vertebra
. So by the end of July, the Vanguard Six were: Gagarin, Bykovskiy, Nelyubov, Nikolayev, Popovich, and Titov.
By January, 1961, these six had all finished parachute and recovery training, as well as three-day regimes in simulators. On January 17, the six participated in their final exams, including time spent in a simulator, and a written test. Based on these results, a commission, supervised by Kamanin, recommended the use of the cosmonauts in the following order: Gagarin, Titov, Nelyubov, Nikolayev, Bykovskiy, Popovich. At this stage Gagarin was the clear favorite to be the first man in space, not only based on the exams, but also among an informal peer evaluation.
in April 1961, was preceded by several preparatory flights. In the summer of 1960, the Soviets learned that the Americans could launch a sub-orbital
manned spaceflight as early as January 1961. Korolev saw this as an important deadline, and was determined to launch a manned orbital mission before the Americans launched their manned suborbital mission. By April 1960, designers at Sergei Korolev's design bureau, then known as OKB-1
, had completed a draft plan for the first Vostok spacecraft, called Vostok 1K. This design would be used for testing purposes; also in their plan was Vostok 2K, a spy satellite that would later become known as Zenit 2, and Vostok 3K, which would be used for all six manned Vostok missions.
Despite the very large geographical size of the Soviet Union, there were obvious limitations to monitoring orbital spaceflights from ground stations within the country. To remedy this, the Soviets stationed about 7 naval vessels, or tracking ships, around the world. For each ground station or tracking ship, the duration of communications with an orbiting spacecraft was limited to five to ten minutes.
The next six launches were all of the Vostok 1K design, equipped with life-support facilities, and planned to be recovered after orbit. The spacecraft launched on July 28, 1960 carried two space dogs, named Chayka and Lisichka. Unfortunately an explosion destroyed the spacecraft shortly after launch, killing both dogs; this mission wasn't given a name. The next mission, designated Korabl-Sputnik 2, was launched on August 19, 1960, carrying two more dogs, Belka and Strelka, as well as a variety of other biological specimens such as mice, insects, and strips of human skin. This mission was successful, and Belka and Strelka became the first living beings recovered from orbit. The spacecraft was only the second object ever to have been recovered from orbit, the first being the return capsule of the American Discoverer 13
the previous week. During the mission there was some concern for Belka and Strelka's health, after images of Belka vomiting had been obtained from the onboard cameras. The spacecraft and dogs were recovered following the 26 hour spaceflight, and extensive physiological tests revealed that the dogs were in good health. This represented a significant success for the Vostok programme.
The success of Korabl-Sputnik 2 gave the designers confidence to put forward a plan leading to a manned spaceflight. A document regarding a plan for the Vostok programme, dated September 10, 1960, and declassified in 1991, was sent to the Central Committee of the Communist Party
, and approved by Premier Nikita Khrushchev
. This document had been signed by the top leaders in the Soviet defence industry at the time, the most senior being Deputy Chairman Dmitriy Ustinov
; this indicated the elevated importance of the document. The plan called for one or two more Vostok 1K flights, followed by two unmanned Vostok 3K flights, followed by a manned flight in December 1960.
A major setback occurred on October 24, when a rocket explosion killed over 100 people, including Chief Marshal
of Artillery Mitrofan Nedelin
, in what is now called the Nedelin catastrophe
. This was one of the worst disasters in the history of spaceflight. It involved a rocket that was not designed by Korolev, and was not necessary for the Vostok programme; the rocket was by rival designer Mikhail Yangel
, intended to be a new generation of Intercontinental ballistic missile
s. It would be two weeks before work on the Vostok programme continued, and it was realised that the original target of a December manned launch was unrealistic.
On December 1, 1960, the next Vostok 1K spacecraft was launched, called Korabl-Sputnik 3 by the press, it carried the two dogs Pchyolka and Mushka. After about 24 hours, the engines were intended to fire to begin reentry, but they fired for less time than had been expected. This meant that the spacecraft would enter the atmosphere, but not over Soviet territory. For this reason the self-destruct system was activated, so the spacecraft and the two dogs, were destroyed. At the time the press reported that an incorrect attitude caused the cabin to be destroyed upon reentry.
The next Vostok 1K spacecraft was launched December 22, 1960, but it was unnamed because it failed to reach orbit. It carried two dogs, named Kometa and Shutka. The third stage of the launch system malfunctioned, and the emergency escape system was activated. The spacecraft landed 3,500 kilometres downrange of the launch site. The resulting rescue operation took several days, in -40 °C
conditions. After a few days, the dogs were both recovered alive, and the spacecraft was returned to Moscow a few weeks later. Despite Korolev's desire to announce this failure to the press, the State Commission vetoed the idea.
would be strapped into the main ejection seat, and unlike the manned missions it had a self-destruct system. The recent failures of Vostok 1K were not encouraging, but it was decided to proceed with launches of an automated variant of Vostok 3KA, the spacecraft design that would conduct a manned spaceflight. The approval of a manned mission was contingent upon the success of the two automated Vostok 3KA missions. Unlike the previous Vostok 1K flights, the two unmanned Vostok 3KA flights were planned to last only a single orbit, to imitate the plan for the first manned flight.
The first of these unmanned flights, Korabl-Sputnik 4, was launched on March 9, 1961. It carried the dog Chernushka into orbit, as well as a mannequin called Ivan Ivanovich
, who wore a functioning SK-1 spacesuit
. The dog was contained in a small pressurized sphere, which also contained 80 mice, several guinea pig
s, and other biological specimens. Additional mice, guinea pigs, and other specimens were placed within the mannequin. After one orbit, the descent module successfully re-entered the atmosphere, the mannequin was safely ejected, and the dog and other specimens landed separated in the descent module by parachute. The spaceflight lasted 106 minutes, and the dog was recovered alive after landing. The mission was a complete success.
On March 23, before the next mission, an accident occurred during training which led to the death of cosmonaut candidate Valentin Bondarenko
. He was burned in a fire in oxygen-rich isolation chamber, and died in a hospital eight hours after the incident. Bondarenko was the first cosmonaut (or astronaut) fatality. It is not clear whether other cosmonauts were told of his death immediately. the media didn't learn of Bondarenko's death – or even of his existence – until many years later, in 1986.
The next unmanned flight, Korabl-Sputnik 5, was launched on March 25, two days after Bondarenko's death. Like the previous Vostok 3KA flight, it lasted for only a single orbit, carried a mannequin and a dog, Zvezdochka ("Starlet", or "Little star"). This mission was also a complete success, which was the final step required to get approval for a manned mission. The re-entry module of the Korabl-Sputnik 5 spacecraft, also called Vostok 3KA-2, is scheduled to be auction
ed at Sotheby's
on April 12, 2011, the 50th anniversary of the first manned spaceflight, Vostok 1
.
All these original missions were cancelled in spring 1964 and the components recycled into the Voskhod programme
, which was intended to achieve more Soviet firsts in space.

Korabl-Sputnik 1
The first Vostok spacecraft was a variant not designed to be recovered from orbit; the variant was also called Vostok 1KP or (1P). At Korolev's suggestion, the media would call the spacecraft Korabl-Sputnik, ("Satellite-ship"); the name Vostok was still a secret codename at this point. This first Vostok spacecraft was successfully sent into orbit on May 15, 1960. Due to a system malfunction, on the spacecraft's 64th orbit, the thrusters fired and sent it into an even higher orbit. The orbit eventually decayed, and it reentered the atmosphere several years later.Vostok 1K

s. It would be two weeks before work on the Vostok programme continued, and it was realised that the original target of a December manned launch was unrealistic.
On December 1, 1960, the next Vostok 1K spacecraft was launched, called Korabl-Sputnik 3 by the press, it carried the two dogs Pchyolka and Mushka. After about 24 hours, the engines were intended to fire to begin reentry, but they fired for less time than had been expected. This meant that the spacecraft would enter the atmosphere, but not over Soviet territory. For this reason the self-destruct system was activated, so the spacecraft and the two dogs, were destroyed. At the time the press reported that an incorrect attitude caused the cabin to be destroyed upon reentry.
The next Vostok 1K spacecraft was launched December 22, 1960, but it was unnamed because it failed to reach orbit. It carried two dogs, named Kometa and Shutka. The third stage of the launch system malfunctioned, and the emergency escape system was activated. The spacecraft landed 3,500 kilometres downrange of the launch site. The resulting rescue operation took several days, in -40 °C

conditions. After a few days, the dogs were both recovered alive, and the spacecraft was returned to Moscow a few weeks later. Despite Korolev's desire to announce this failure to the press, the State Commission vetoed the idea.
Vostok 3KA
The two unmanned missions immediately preceding the first manned flight used the same spacecraft design as in the manned missions, a design called Vostok 3KA (or 3A). The only differences were they would carry a single dog into orbit, a life-size mannequinMannequin

would be strapped into the main ejection seat, and unlike the manned missions it had a self-destruct system. The recent failures of Vostok 1K were not encouraging, but it was decided to proceed with launches of an automated variant of Vostok 3KA, the spacecraft design that would conduct a manned spaceflight. The approval of a manned mission was contingent upon the success of the two automated Vostok 3KA missions. Unlike the previous Vostok 1K flights, the two unmanned Vostok 3KA flights were planned to last only a single orbit, to imitate the plan for the first manned flight.
The first of these unmanned flights, Korabl-Sputnik 4, was launched on March 9, 1961. It carried the dog Chernushka into orbit, as well as a mannequin called Ivan Ivanovich

s, and other biological specimens. Additional mice, guinea pigs, and other specimens were placed within the mannequin. After one orbit, the descent module successfully re-entered the atmosphere, the mannequin was safely ejected, and the dog and other specimens landed separated in the descent module by parachute. The spaceflight lasted 106 minutes, and the dog was recovered alive after landing. The mission was a complete success.
On March 23, before the next mission, an accident occurred during training which led to the death of cosmonaut candidate Valentin Bondarenko

Valentin Vasiliyevich Bondarenko was a Soviet fighter pilot and cosmonaut. He died during a training accident in Moscow, USSR, in 1961. A crater on the Moon's far side is named for him.-Education and military training:...
. He was burned in a fire in oxygen-rich isolation chamber, and died in a hospital eight hours after the incident. Bondarenko was the first cosmonaut (or astronaut) fatality. It is not clear whether other cosmonauts were told of his death immediately. the media didn't learn of Bondarenko's death – or even of his existence – until many years later, in 1986.
The next unmanned flight, Korabl-Sputnik 5, was launched on March 25, two days after Bondarenko's death. Like the previous Vostok 3KA flight, it lasted for only a single orbit, carried a mannequin and a dog, Zvezdochka ("Starlet", or "Little star"). This mission was also a complete success, which was the final step required to get approval for a manned mission. The re-entry module of the Korabl-Sputnik 5 spacecraft, also called Vostok 3KA-2, is scheduled to be auction
