Vostok 3 launched 1962
To further test the effect of microgravity on the human body, Vostok 3, carrying cosmonaut Andriyan Nikolayev, was launched August 11, 1962. Nikolayev spent 4 days in space orbiting Earth 64 times before returning August 15. During his first day in space, Nikolayev unstrapped himself from his seat and floated freely, the first time a human had done this.
August 15, Nikolayev, the third cosmonaut in space, returned to Earth but he ejected from the spacecraft and landed separately.
