The Voskhod programme was the second Soviet human spaceflight project. Two one-day crewed missions were flown using the Voskhod spacecraft and rocket, one in 1964 and one in 1965, and two dogs flew on a 22-day mission in 1966. Voskhod development was both a follow-on to the Vostok programme and a recycling of components left over from that programme's cancellation following its first six flights. The Voskhod programme was superseded by the Soyuz programme.
