After the flight of
Vostok 6, Yorkina worked on the
Voskhod 2 mission in 1965 which included the first spacewalk. She was appointed afterwards as backup commander for the Voskhod 4 mission. This was a 20-day single man mission which studied long term weightlessness with various experiments. The mission was cancelled in 1966 leaving Yorkina to train for the
Soyuz spacecraft until the eventual disbanding of the female cosmonaut team. Yorkina was considered one of the least capable of the five female cosmonauts, and
Nikolai Kamanin specifically complained that she was "too fond of chocolate and cakes". Another issue that arose for Voskhod 5 was that Zvezda, the company that developed the spacesuits, declined to fabricate a special EVA suit for the women. This caused further delays and the eventual cancellation of any more Voskhod missions after Vostok 6. Following the death of
Sergei Korolev, the space program was halted and all cosmonauts were moved to the development of the Soyuz. Following cancellation of the
Voskhod Program, Yorkina worked at the
Yuri Gagarin Cosmonaut Training Center, and was one of the cosmonauts involved in development of the
Spiral spaceplane. She retired from the space program on 1 October 1969, and from active military duty in 1989. She achieved the rank of Lieutenant Colonel in the Air Force Reserve. ==References==
