Model of the Vostok capsule with its carrier rocket's upper stage
Vostok 3 (Russian: Восток-3, lit. 'Orient 3' or 'East 3') and Vostok 4 (Восток-4, 'Orient 4' or 'East 4') were Soviet space program flights in August 1962, intended to determine the ability of the human body to function in conditions of weightlessness, test the ground control capability to launch and manage two separate, concurrent flights, and test the endurance of the Vostok 3KA spacecraft over longer flights. Cosmonaut Andriyan Nikolayev orbited the Earth 64 times in Vostok 3 over nearly four days in space, August 11–15, 1962, a feat which would not be matched by NASA until the Gemini program (1965–1966). Pavel Popovich was launched on Vostok 4 on August 12, and made 48 Earth orbits. The two capsules were launched on trajectories that brought the spacecraft within approximately 6.5 km (4.0 mi) of each another.
