Yuri Gagarin and Vostok 1 (1961): First Human in Space

Yuri Gagarin became the first human in space on 12 April 1961, when the Soviet spacecraft Vostok 1 carried him once around the Earth in about 108 minutes. Launched from the Baikonur Cosmodrome in Soviet Kazakhstan and landing near the Volga River, the 27-year-old air force pilot proved that people could survive launch, weightlessness and re-entry. The flight was a major Soviet triumph in the Cold War Space Race and turned Gagarin into one of the most famous people in the world.

Background: the Soviet path to human spaceflight

The Soviet Union had already shocked the world with Sputnik 1, the first artificial satellite, in October 1957, and with Laika, the dog carried into orbit on Sputnik 2 a month later. The engine of these successes was the R-7, the world’s first intercontinental ballistic missile, designed by the bureau of Sergei Korolev, the chief designer whose identity was kept secret until his death in 1966.

In 1959 the Soviet leadership approved a crewed spacecraft, later called Vostok (“East”). It consisted of a spherical descent module about 2.3 metres in diameter, where the cosmonaut sat in an ejection seat, attached to a conical instrument module carrying the retro-rocket and supplies. Launched on a three-stage version of the R-7, the whole spacecraft weighed about 4.7 tonnes.

In 1960 the air force selected 20 young military pilots as the first cosmonaut group. They had to be short and light enough to fit the cramped capsule. From them, a smaller group of six trained most intensively, and by early April 1961 the final choice lay between Yuri Gagarin and Gherman Titov.

Testing and risks

Vostok was tested in a series of uncrewed flights, several carrying dogs, in 1960 and 1961. The results were mixed. In July 1960 a launch failure killed two dogs, and in December 1960 another spacecraft was lost during re-entry. Only the last two test flights, in March 1961, each carrying a dog and a mannequin nicknamed “Ivan Ivanovich”, went fully to plan.

The risks remained high. Doctors were unsure whether a person could think or function properly in weightlessness. The capsule had no backup retro-rocket; instead its orbit was designed to be low enough that, if the engine failed, atmospheric drag would bring it down within about ten days, and it carried supplies for that period. Because of fears that the cosmonaut might be incapacitated, the manual controls were locked, and the code to unlock them was placed in a sealed envelope on board.

The United States was also preparing to send an astronaut on a suborbital flight. Soviet leaders were keen to make sure their country flew first.

The choice of Gagarin

Yuri Alekseyevich Gagarin was born on 9 March 1934 in the village of Klushino, in the Smolensk region west of Moscow, into a family of collective-farm workers. During the Second World War the area was occupied by German forces. After training as a foundry worker and attending an industrial technical school in Saratov, where he learned to fly at a local aero club, he joined the Soviet air force and became a fighter pilot stationed in the Arctic near Murmansk.

Gagarin did well in training, was popular with his colleagues and was considered calm under pressure. His modest rural background also suited the image the Soviet state wished to present. On 8 April 1961 a state commission confirmed him as pilot of the first flight, with Titov as backup.

The flight of Vostok 1

On the morning of 12 April 1961 Gagarin, wearing an orange pressure suit, was sealed into the capsule on the launch pad at Tyuratam, the site later known as Baikonur. His radio call sign was “Kedr” (Cedar). At 9:07 a.m. Moscow time, as the engines roared and the rocket lifted off, he called out “Poyekhali!” (“Let’s go!”).

The rocket placed Vostok 1 into an orbit ranging roughly from 170 to 330 kilometres above the Earth. Gagarin passed over Siberia and the Pacific Ocean, crossed the southern tip of South America and headed across the South Atlantic towards Africa. He reported his observations and condition, ate and drank, and noted the colours of the Earth and the horizon. Ground stations followed him only part of the way, and much of the orbit was out of radio contact.

Over Africa, at around 10:25 a.m., the automatic system fired the retro-rocket. The instrument module was supposed to separate from the descent capsule, but a bundle of cables failed to part, and the joined craft spun rapidly for about ten minutes until the cables burned through in the heat of re-entry. Gagarin experienced heavy deceleration forces, then the capsule steadied.

At an altitude of about 7 kilometres, as planned, Gagarin ejected from the capsule and descended by his own parachute. Both he and the capsule landed safely near the village of Smelovka, south-west of Engels in the Saratov region, at about 10:55 a.m. Moscow time. A farmer’s wife, Anna Takhtarova, and her granddaughter were among the first people to see him walking across the field in his orange suit.

News and celebration

The Soviet news agency TASS announced the flight while Gagarin was still in orbit. During the mission he was promoted from senior lieutenant directly to major. Reaction around the world was enormous. On 14 April 1961 hundreds of thousands of people filled the streets of Moscow, and Gagarin was greeted by Nikita Khrushchev at a huge rally in Red Square.

Gagarin then became the Soviet Union’s most effective ambassador. In the following years he toured dozens of countries; in July 1961 he visited Britain, where he was welcomed by large crowds in London and Manchester and met Queen Elizabeth II.

Key people

• Yuri Gagarin (1934–1968), Soviet air force pilot and the first human in space.
• Sergei Korolev (1907–1966), chief designer of the R-7 rocket and the Vostok spacecraft.
• Gherman Titov (1935–2000), Gagarin’s backup, who flew Vostok 2 for a full day in August 1961.
• Nikolai Kamanin (1908–1982), air force general in charge of cosmonaut training.
• Nikita Khrushchev (1894–1971), Soviet leader who used the flight as proof of the Soviet system’s success.

Consequences

Gagarin’s flight was a severe blow to American prestige, coming just before the failed Bay of Pigs invasion of Cuba later that month. On 5 May 1961 Alan Shepard became the first American in space on a 15-minute suborbital flight. On 25 May 1961 President John F. Kennedy asked Congress to commit the United States to landing a man on the Moon before the end of the decade, a goal achieved with the Apollo 11 Moon landing in 1969.

The Soviet Union followed up with further firsts, including Titov’s day-long flight, the first group flights, and in 1963 the flight of Valentina Tereshkova, the first woman in space. Gagarin himself trained for later missions, serving as backup for Soyuz 1 in 1967, but he was never allowed to fly in space again, as the authorities were unwilling to risk losing a national hero.

On 27 March 1968 Gagarin died with instructor Vladimir Seryogin when their MiG-15UTI trainer crashed near Kirzhach in the Vladimir region. He was 34. His ashes were placed in the Kremlin Wall, and his hometown of Gzhatsk was renamed Gagarin.

Myths and facts

Myth: Gagarin landed inside Vostok 1. For years Soviet accounts implied that he had come down in his spacecraft, because the record rules of the Fédération Aéronautique Internationale were understood to require it. In fact, ejection was always part of the plan, and Soviet sources openly confirmed it only in the 1970s.

Myth: other cosmonauts secretly died in space before Gagarin. Rumours of “lost cosmonauts” circulated in the West from the late 1950s. When Soviet archives opened after 1991 they showed no evidence of any such flights. Some cosmonaut trainees did die in accidents, most notably Valentin Bondarenko in a fire in a ground test chamber in March 1961, but no one flew in space before Gagarin.

Myth: Gagarin flew the spacecraft. Vostok 1 was controlled automatically and from the ground. Gagarin monitored the systems and could have taken manual control in an emergency, but he did not need to.

Why it matters

Gagarin’s single orbit opened the age of human spaceflight. It showed that people could survive and work beyond the atmosphere, set off a faster Space Race that led to the Moon, and made Gagarin an enduring global symbol of exploration. Each year on 12 April his flight is marked around the world as the beginning of human journeys into space.
