Vostok 2 was the second crewed mission of the Soviet Vostok program and the first human spaceflight to last more than a single day. It was launched from Baikonur Cosmodrome on August 6, 1961, carrying cosmonaut Gherman Titov, who became the second Soviet person to orbit Earth. His flight demonstrated that a human could remain functional in space for an extended period and perform tasks while experiencing weightlessness.

During his mission, Titov completed over 17 orbits around the Earth, surpassing Yuri Gagarin's single orbit during Vostok 1, as well as the suborbital flights of American astronauts Alan Shepard and Gus Grissom on their Mercury-Redstone 3 and 4 missions. Titov's record for orbits and flight duration would remain unmatched by an American astronaut until Gordon Cooper's Mercury-Atlas 9 flight in May 1963. He became the first person to spend a full day in space and the first to sleep in orbit.

A primary objective of Vostok 2 was to assess how humans would respond to prolonged spaceflight and weightlessness. During the mission, Titov experienced space motion sickness, including nausea and vomiting, highlighting some of the challenges of extended time in orbit. As the effects of weightlessness on the human body were still not well understood, his experience provided valuable medical information for planning longer-duration missions and demonstrated the need for astronauts to adapt to the space environment.

Titov photographed Earth from orbit, producing some of the earliest photographs taken by a human from space. He also used a movie camera to record scenes inside the spacecraft and views of Earth.

Like Vostok 1, Vostok 2 was largely an automatically controlled spacecraft. The Vostok design was intended to perform the major phases of flight automatically, reducing the need for the cosmonaut to pilot the spacecraft. Titov nevertheless conducted exercises involving the spacecraft's manual controls. This provided experience for future missions in which increasingly sophisticated piloting and maneuvering capabilities would be required.

Vostok 2 completed its mission on August 7, 1961, after approximately 25 hours 18 minutes in space and 17 orbits. As with the other Vostok missions, Titov ejected from the descent module at high altitude and landed separately by parachute. This was part of the Vostok spacecraft's standard landing procedure.
