Second manned orbital flight. The Soviet Union successfully launched Vostok II into orbit with Gherman S. Titov as pilot. The spacecraft carried life-support equipment,
radio and television for monitoring the condition of the cosmonaut, tape recorder, telemetry system, biological experiments, and automatic and manual control equipment.
After 17.5 orbits, the spacecraft reentered on August 7 and landed safely at 7:18 GMT near Krasny Kut, Saratov. Titov made a separate parachute landing in an ejector
couch. Flight objectives: 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.
