Voskhod 1 (Russian: Восход-1, lit. 'Sunrise-1') was the seventh crewed Soviet space flight. Flown by cosmonauts Vladimir Komarov, Konstantin Feoktistov, and Boris Yegorov, it launched 12 October 1964, and returned on the 13th. Voskhod 1 was the first human spaceflight to carry more than one crewman into orbit, the first flight without the use of spacesuits, and the first to carry either an engineer or a physician into outer space. It also set a crewed spacecraft altitude record of 336 km (209 mi).
