Answer:
Valentina Tereshkova
Step-by-step explanation:
On June 16, 1963, aboard Vostok 6, Soviet Cosmonaut Valentina Tereshkova becomes the first woman to travel into space. After 48 orbits and 71 hours, she returned to earth, having spent more time in space than all U.S. astronauts combined to that date.
Many people say Sally K. RIde was the first woman astronaut in space but that is incorrect as she was the first AMERICAN woman astronaut in space.
Sally K. Ride was launched by NASA on June 18, 1983, 20 years after Valentina Tereshkova.
