USSR 1964 Voskhod 1

Voskhod 1 was the world's first multicrew spaceflight. Launched on October 12, 1964, the Voskhod 1 spacecraft carried Soviet engineer Konstantin Feoktistov, and medical physician Boris Yegorov into outer space together with cosmonaut pilot Vladimir Komarov.

The Voskhod spacecraft was added with a solid-fuel braking rocket to provide a softer landing at touchdown. It was considered a potentially dangerous mission with no spacesuits for the crew, no ejection seats were fitted in the spacecraft and no escape tower provided for the crew in the event of a launching or landing emergency! Voskhod 1 was devoted to biomedical research, and to the study of how a multi-disciplinary team could work together in space.
