Vostok 2
The Soviet Union launches its second manned spacecraft, Vostok 2, with cosmonaut Gherman Titov aboard. This mission sets a new space endurance record, with Titov spending just over one day in orbit, circling Earth 17 times in the process. Later accounts show that it’s not a pleasant day in orbit: Titov is reportedly the first sufferer of space sickness, vomiting in the cabin of his Vostok capsule.
