Second manned orbital flight. Titov was the first, who slept during his mission and the first, who had problems with space sickness. Investigation of the effects on the human organism of a prolonged flight in orbit and subsequent return to the surface of the Earth; investigation of man's ability to work during a prolonged period of weightlessness. Titov took manual control of spacecraft but suffered from space sickness. He also experienced problems with separation of the service module after retrofire.
Recovered after 17 orbits, August 7, 1961 7:18 GMT. Landed near Krasny Kut, Saratov. Titov was never to fly again, after being assigned to the Spiral spaceplane, which turned out to be a dead-end project. A biography of him by Martin Caidin ('I Am Eagle') made him somewhat more accessible than Gagarin to the West.
