Valeri Kubasov

Valery Nikolaevich Kubasov (Russian: Вале́рий Никола́евич Куба́сов; 7 January 1935 – 19 February 2014) was a Soviet and Russian cosmonaut who flew on two missions in the Soyuz programme as a flight engineer: Soyuz 6 and Soyuz 19 (the Apollo–Soyuz mission), and commanded Soyuz 36 in the Intercosmos programme. On 21 July 1975, the Soyuz 7K-TM module used for ASTP landed in Kazakhstan at 5:51 p.m. and Kubasov was the first to exit the craft. Kubasov performed the first welding experiments in space, along with Georgy Shonin.

Kubasov was also involved in the development of the Mir space station. He retired from the Russian space program in November 1993 and was later deputy director of RKK Energia.
