Valeri Kubasov

Valeri Nikolayevich Kubasov (Вале́рий Никола́евич Куба́сов) was a Soviet/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.
