Vostok 1 (Восто́к, East or Orient 1) was the first spaceflight of the Vostok programme and the first crewed spaceflight in history.
The first human spaceflight was launched by the Soviet Union on 12 April 1961 as a part of the Vostok program, with cosmonaut Yuri Gagarin aboard.

Vostok programme

Vostok 1 (Восто́к, East or Orient 1) was the first spaceflight of the Vostok programme and the first crewed spaceflight in history. The Soviet Union secretly pursued the Vostok programme in competition with the United States' Project Mercury.
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.

Yuri Alekseyevich Gagarin (9 March 1934 – 27 March 1968) was a Soviet Air Forces pilot and cosmonaut who became the first human to journey into outer space, achieving a major milestone in the Space Race; his capsule Vostok 1 completed one orbit of Earth on 12 April 1961.

Yuri Gagarin, 27, was chosen as the prime pilot of Vostok 1, with Gherman Titov and Grigori Nelyubov as backups.
Gherman Stepanovich Titov (Герман Степанович Титов; 11 September 1935 – 20 September 2000) was a Soviet cosmonaut who, on 6 August 1961, became the second human to orbit the Earth, aboard Vostok 2, preceded by Yuri Gagarin on Vostok 1.

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. Vostok launched several precursor uncrewed missions between May 1960 and March 1961, to test and develop the Vostok rocket family and space capsule.
The first human spaceflight was accomplished with Vostok 1 on April 12, 1961, by Soviet cosmonaut Yuri Gagarin.

Korabl-Sputnik 5

These missions had varied degrees of success, but the final two—Korabl-Sputnik 4 and Korabl-Sputnik 5—were complete successes, allowing the first crewed flight.
It was the last test flight of the Vostok spacecraft design prior the first manned flight, Vostok 1.

Vostok 2

Kamanin was referring to the second mission, Vostok 2, compared to the relatively short single-orbit mission of Vostok 1.
Titov orbited the Earth over 17 times, exceeding the single orbit of Yuri Gagarin on Vostok 1 − as well as the suborbital spaceflights of American astronauts Alan Shepard and Gus Grissom aboard their respective Mercury-Redstone 3 and 4 missions.

The first human in space was Soviet Yuri Gagarin, who was launched on April 12, 1961, aboard Vostok 1 and orbited around the Earth for 108 minutes.

Space Race

The Space Race between the Soviet Union and the United States, the two Cold War superpowers, began just before the Soviet Union launched the world's first artificial satellite, Sputnik 1, in 1957.
On April 12, 1961, the USSR surprised the world again by launching Yuri Gagarin into a single orbit around the Earth in a craft they called Vostok 1.

Yuri Gagarin, 27, was chosen as the prime pilot of Vostok 1, with Gherman Titov and Grigori Nelyubov as backups.
For Vostok 1 Nelyubov was chosen as second backup for Gagarin and presumably first backup for Vostok 2 for Titov in April and August 1961 respectively.

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.
This was followed by the first human spaceflight in 1961, when Yuri Gagarin was sent into orbit on Vostok 1.

Vostok-K

At Baikonur Cosmodrome on the morning of April 11, 1961, the Vostok-K rocket, together with the attached Vostok 3KA space capsule, were transported several kilometers to the launch pad, in a horizontal position.
On 12 April 1961, a Vostok-K rocket was used to launch Vostok 1, the first manned spaceflight, which made Yuri Gagarin the first human to fly in space.

The final decision of who would fly the mission relied heavily on the opinion of the head of cosmonaut training, Nikolai Kamanin.
The next day, Gagarin lifted off in Vostok 1, made a full orbit and safely landed 23 kilometers from Saratov.

Cosmonautics Day

April 12 was declared Cosmonautics Day in the USSR, and is celebrated today in Russia as one of the official "Commemorative Dates of Russia."
In 2011, 12 April was declared as the International Day of Human Space Flight in dedication of the first manned space flight made on 12 April 1961 by the 27-year-old Russian Soviet cosmonaut Yuri Gagarin.

Orbital spaceflight

The orbital spaceflight consisted of a single orbit around Earth which skimmed the upper atmosphere at 169 km at its lowest point.

Yuri Levitan

Gagarin's flight was announced while Gagarin was still in orbit, by Yuri Levitan, the leading Soviet radio personality since the 1930s.
He announced on Radio Moscow all major international events in the 1940s–60s including the German attack on the Soviet Union on 22 June 1941, the surrender of Germany on 9 May 1945, the death of Joseph Stalin on 5 March 1953, and the first manned spaceflight on 12 April 1961.

International Day of Human Space Flight

In 2011, it was declared the International Day of Human Space Flight by the United Nations.
Yuri Gagarin crewed the Vostok 1 space flight in 1961, making one orbit around the Earth over 108 minutes in the Vostok 3KA spacecraft launched by Vostok-K launch vehicle.

According to a 2014 obituary, Vostok's chief designer, Oleg Ivanovsky, personally helped rebolt the hatch.
Ivanovsky personally helped Yuri Gagarin mount the gantry and climb into Vostok 1 and helped rebolt the hatch after Gagarin complained that it had not been closed and sealed correctly.

Reentry capsule

Ten seconds after retrofire, commands were sent to separate the Vostok service module from the reentry module (code name "little ball", but the equipment module unexpectedly remained attached to the reentry module by a bundle of wires.
Soyuz 5 almost ended in disaster, when the reentry capsule entered the atmosphere nose first – attributed to a failure of the service module to separate similar to that on the Vostok 1 flight.

Space Age

The resulting film, First Orbit, was released online to celebrate the 50th anniversary of human spaceflight.
First Orbit is a 2011 feature-length, experimental documentary film about Vostok 1, the first manned space flight around the Earth.
