Valentina Tereshkova Became the First Woman in Space in 1963
On June 16, 1963, Soviet cosmonaut Valentina Tereshkova launched aboard Vostok 6, becoming the first woman — and at 26, the youngest woman — to fly in space. She orbited Earth 48 times over three days, logging more time in space than all American astronauts combined at that point. A textile worker and amateur parachutist before her selection, she remains the only woman to have completed a solo space mission.
