Vostok 5
Vostok 5 (Russian: Восток-5, lit. 'Orient 5' or 'East 5') was a joint mission of the Soviet space program together with Vostok 6; as with the previous pair of Vostok 3 and Vostok 4 the two Vostok spacecraft came close to one another in orbit and established a radio link. Vostok 5 launched on 14 June 1963, and returned to Earth on 19 June, and was piloted by Valery Bykovsky.
