The mission logo for the joint flights of Vostok 5 and 6.

On this date in 1963, the Soviet spacecraft Vostok 5 is rolled out to its launch pad, near Vostok 6. After final testing, both spacecraft are declared ready for launch of the very first mission to rendezvous two spacecraft. Vostok 5 is flown by cosmonaut Valeri Bykovsky, and Vostok 6 by Valentina Tereshkova — who was about to become the first woman in space.
