Answer
Vostok 2 was the spacecraft piloted by Gherman Titov, a Soviet cosmonaut, during his historic space mission in 1961. Titov's flight marked a significant milestone in space exploration, as he became the second human to orbit Earth, following Yuri Gagarin's pioneering mission just a few months earlier. Vostok 2 completed 17 orbits around the planet, demonstrating the feasibility of extended space travel and paving the way for future human spaceflights.
