Vladimir Aleksandrovich Shatalov (Russian: Владимир Александрович Шаталов; born December 8, 1927) was a Soviet cosmonaut who flew three space missions of the Soyuz programme: Soyuz 4, Soyuz 8, and Soyuz 10. Shatalov was born in Petropavlovsk. From 1971 to 1987, he was Commander of Cosmonaut Training, and Director of the Cosmonaut Training Centre from then until 1991. Quote: "When we look into the sky it seems to us to be endless. We breathe without thinking about it, as is natural... and then you sit aboard a spacecraft, you tear away from Earth, and within ten minutes you have been carried straight through the layer of air, and beyond there is nothing! The 'boundless' blue sky, the ocean which gives us breath and protects us from endless black and death, is but an infinitesimally thin film. How dangerous it is to threaten even the smallest part of this gossamer covering, this conserver of life."

Aleksei Stanislavovich Yeliseyev (Russian: Алексей Станиславович Елисеев; born July 13, 1934) is a retired Soviet cosmonaut who flew on three missions in the Soyuz programme as a flight engineer: Soyuz 5, Soyuz 8, and Soyuz 10. Aleksei's father was Lithuanian with the last name Kuraitis, who died in the Soviet's Gulag as an enemy of the people. Aleksei uses his mother's last name "Yeliseyev" so some regard him as also being a Lithuanian cosmonaut.

Nikolay Nikolayevich Rukavishnikov was a Soviet cosmonaut who flew three space missions of the Soyuz programme: Soyuz 10, Soyuz 16, and Soyuz 33. Two of these missions, Soyuz 10 and Soyuz 33 were intended to dock with Salyut space stations, but failed to do so.
