Vostok 2 carried cosmonaut Gherman Titov into orbit for a full day in order to study the effects of a more prolonged period of weightlessness on the human body.
Unlike Yuri Gagarin on Vostok 1 Titov took manual control of the spacecraft for a short while.
The flight was an almost complete success, marred only by a bout of space sickness[?] and a troublesome re-entry when the re-entry module failed to separate cleanly from its service module.
The re-entry capsule was unfortunately destroyed during development of the Voskhod[?] spacecraft.
