Valentina Vladimirovna Tereshkova was born to a peasant family in Maslennikovo, Russia, in 1937. She began work at a textile factory when she was 18, and at age 22 she made her first parachute jump under the auspices of a local aviation club. Her enthusiasm for skydiving brought her to the attention of the Soviet space program, which sought to put a woman in space in the early 1960s as a means of achieving another “space first” before the United States. As an accomplished parachutist, Tereshkova was well equipped to handle one of the most challenging procedures of a Vostok space flight: the mandatory ejection from the capsule at about 20,000 feet during reentry. In February 1962, she was selected along with three other woman parachutists and a female pilot to begin intensive training to become a cosmonaut.
In 1963, Tereshkova was chosen to take part in the second dual flight in the Vostok program, involving spacecrafts Vostok 5 and Vostok 6. On June 14, 1963, Vostok 5 was launched into space with cosmonaut Valeri Bykovsky aboard. With Bykovsky still orbiting the earth, Tereshkova was launched into space on June 16 aboard Vostok 6. The two spacecrafts had different orbits but at one point came within three miles of each other, allowing the two cosmonauts to exchange brief communications.
After her historic space flight, Valentina Tereshkova received the Order of Lenin and Hero of the Soviet Union awards. In November 1963, she married fellow cosmonaut Andrian Nikolayev, reportedly under pressure from Soviet leader Nikita Khrushchev, who saw a propaganda advantage in the pairing of the two single cosmonauts.
