Vladimir Kovalyonok (1942) is a retired Soviet cosmonaut. He entered the Soviet space program on July 5, 1967 and was commander of three missions Soyuz 25, Soyuz 29, Soyuz T-4. He retired from the cosmonaut team on June 23, 1984. From 1990 to 1992 he was a Director of the 30th Scientific Research Institute, Ministry of Defense

Aleksandr Ivanchenkov (1940) is a retired Soviet cosmonaut who flew as Flight Engineer on Soyuz 29 and Soyuz T-6, he spent 147 days, 12 hours and 37 minutes in space. Valery Bykovsky (1934 – 2019) was a Soviet cosmonaut who flew on three space flights: Vostok 5, Soyuz 22, Soyuz 31. He was also backup for Vostok 3 and Soyuz 37 He flew Soyuz 31 mission to Salyut 6 space station with the East German Sigmund Jähn. It was launched on 26 August 1978. They joined two other cosmonauts V. Kovalyonok and A. Ivanchenkov on the space station that had arrived on Soyuz 29 . The four conducted biological experiments on themselves during their stay. Bykovsky and Jähn undocked from the station in the Soyuz 29 capsule on 3 September and landed back on Earth later that day.

Pyotr Klimuk (1942) is a former Soviet cosmonaut and the first Belarussian to perform space travel. Klimuk is veteran of 3 space flight missions. Klimuk attended the Leninsky Komsomol Chernigov High Aviation School and entered the Soviet Air Force in 1964. The following year, he was selected to join the space program. His first flight was a long test flight on Soyuz 13 in 1973. This was followed by a mission to the Salyut 6 space station on Soyuz 18 in 1975. From 1976 he became involved in the Intercosmos and made his third and final spaceflight on an Intercosmos flight with Polish cosmonaut Miroslaw Hermaszewski on Soyuz 30 in 1978. He resigned from the cosmonaut team in 1978 to take up a position as the Assistant to the Chief of the Gagarin Cosmonaut Training Center. In 1991, he was promoted to Chief of that facility and remained in that post until retirement in 2003. Klimuk is a graduate of the Gagarin Air Force Academy and the Lenin Military-Political Academy. He is the author of two books on human spaceflight: Beside the Stars, and Attack on Weightlessness.

Mirosław Hermaszewski (1941) is a former Polish cosmonaut, fighter plane pilot, and retired Polish Air Force officer. He became the first, and to this day remains the only Polish national in space when he flew aboard the Soyuz 30 spacecraft in 1978. He was the 89th human to reach outer space. n 1976, he was chosen from a pool of 500 Polish military pilots to take part in the Interkosmos space program. Together with Soviet cosmonaut Pyotr Klimuk, spent eight days aboard the Salyut 6 space station (27 June - 5 July 1978). During their time in orbit, Klimuk and Hermaszewski carried out various geoscience experiments and photographed the Earth – orbiting it 126 times. Over the duration of their stay at the space station, Hermaszewski and Klimuk—sometimes with the aid of Vladimir Kovalyonok and Aleksandr Ivanchenkov, the two other cosmonauts who had already been stationed at Salyut 6 prior to the arrival of the Soyuz 30 mission—carried out a total of eleven different experiments while in space that had been planned internationally as part of the program. After the spaceflight, Hermaszewski achieved hero status in the countries of the Eastern Block and was awarded with several high honors, including the rarely given to foreigners Hero of the Soviet Union title for his participation in the mission. A massive information and propaganda campaign around the Soyuz 30 mission and its participants was launched by the Polish government in coordination with the USSR and other allied states in the Warsaw Pact. In 1985, he co-founded the Association of Space Explorers. Hermaszewski later became President of the Polish Astronautic Society (a position he held from 1986 to 1990).
