Flight record6 flights6 crewed · 0 uncrewed

First flown missionVostok 1April 12, 1961

Latest flown missionVostok 6June 16-June 19, 1963

Core capabilities

Human orbital flight

Proved a person could launch, live and work briefly in orbit, and return safely.

Flight endurance

Expanded from one orbit to missions lasting several days.

Paired operations

Vostok 3 and 4, then Vostok 5 and 6, operated concurrently in orbit.

Recovery

Used automatic followed by cosmonaut ejection and a separate parachute landing.

Program story

Vostok 1 carried Yuri Gagarin around Earth on April 12, 1961, making him the first human in space and orbit. The flight proved the basic spacecraft, launch, tracking, life-support, reentry, and recovery system.

The next five missions expanded endurance and operational experience. Gherman Titov spent more than a day in orbit, while the Vostok 3/4 and Vostok 5/6 pairs placed two crewed spacecraft in orbit at the same time.

Valentina Tereshkova flew Vostok 6 in June 1963 and became the first woman in space. The program's compact spacecraft then became the basis for Voskhod's multi-person and EVA missions.
