First Woman in Space.
While working in a textile mill, Tereshkova joined a parachuting club, where she made 150 jumps. With that experience, she wrote a letter to the space center asking if she could join.
The Soviet space officials were already putting together a group of women for the next cosmonaut team. So in 1961, they decided to choose Tereshkova to join the next class of people to go to space.
After rigorous training, she was launched into space for a 70-hour-and-50-minute flight that resulted in 45 revolutions around Earth.
