Valentina Tereshkova - Career in The Soviet Space Program

Career in The Soviet Space Program

After the flight of Yuri Gagarin in 1961, Sergey Korolyov, the chief Soviet rocket engineer, came up with the idea of putting a woman in space. On 16 February 1962, Valentina Tereshkova was selected to join the female cosmonaut corps. Out of more than four hundred applicants, five were selected: Tatyana Kuznetsova, Irina Solovyova, Zhanna Yorkina, Valentina Ponomaryova, and Tereshkova. Qualifications included that they be parachutists under 30 years of age, under 170 cm (5 feet 7 inches) tall, and under 70 kg (154 lbs.) in weight.

Tereshkova was considered a particularly worthy candidate, partly due to her "proletarian" background, and because her father, tank leader sergeant Vladimir Tereshkov, was a war hero. He died in the Finnish Winter War during WWII in the Lemetti area in Finnish Karelia when Tereshkova was two years old. After her mission she was asked how the Soviet Union should thank her for her service to the country. Tereshkova asked that the government search for, and publish, the location where her father was killed in action. This was done, and a monument now stands at the site in Lemetti—now on the Russian side of the border. Tereshkova has since visited Finland several times.

Training included weightless flights, isolation tests, centrifuge tests, rocket theory, spacecraft engineering, 120 parachute jumps and pilot training in MiG-15UTI jet fighters. The group spent several months in intensive training, concluding with examinations in November 1962, after which four remaining candidates were commissioned Junior Lieutenants in the Soviet Air Force. Tereshkova, Solovyova and Ponomaryova were the leading candidates, and a joint mission profile was developed that would see two women launched into space, on solo Vostok flights on consecutive days in March or April 1963.

Originally it was intended that Tereshkova would launch first in Vostok 5 while Ponomaryova would follow her into orbit in Vostok 6. However, this flight plan was altered in March 1963. Vostok 5 would now carry a male cosmonaut Valery Bykovsky flying the joint mission with a woman aboard Vostok 6 in June 1963. The State Space Commission nominated Tereshkova to pilot Vostok 6 at their meeting on 21 May and this was confirmed by Nikita Khrushchev himself. At the time of her selection, Tereshkova was exactly ten years younger than the youngest Mercury Seven astronaut, Gordon Cooper.

After watching the successful launch of Vostok 5 on 14 June, Tereshkova began final preparations for her own flight. She was 26 at the time. On the morning of 16 June 1963, Tereshkova and her back-up Solovyova were both dressed in spacesuits and taken to the launch pad by bus. After completing her communication and life support checks, she was sealed inside the Vostok. After a two-hour countdown, Vostok 6 launched faultlessly, and Tereshkova became the first woman in space. Her call sign in this flight was Chaika (English: Seagull; Russian: Ча́йка), later commemorated as the name of an asteroid, 1671 Chaika.

Although Tereshkova experienced nausea and physical discomfort for much of the flight, she orbited the earth 48 times and spent almost three days in space. With a single flight, she logged more flight time than the combined times of all American astronauts who had flown before that date. Tereshkova also maintained a flight log and took photographs of the horizon, which were later used to identify aerosol layers within the atmosphere.

Vostok 6 was the final Vostok flight and was launched two days after Vostok 5 which carried Valery Bykovsky into a similar orbit for five days, landing three hours after Tereshkova. The two vessels approached each other within 5 kilometres (3.1 mi) at one point, and Tereshkova communicated with Bykovsky and with Khrushchev by radio.

Even though there were plans for further flights by women, it took 19 years until the second woman, Svetlana Savitskaya, flew into space. None of the other four in Tereshkova's early group flew, and in October 1969 the pioneering female cosmonaut group was dissolved.
