- Sevastanyov was manager of the
Soviet lunar mission training group in 1967, and flew on Soyuz 9 in
1970, and Soyuz 18/Salyut 4 in 1975. He actually flew into space
only twice, although he was a crew member of three separate
spacecraft in the course of the two mssions. During his career
he spent a total of 80 days, 16 hours, and 19 minutes in space.
Sevastanyov was a member of the back-up crew for the original
Soyuz 18 which failed to reach orbit on April 5, 1975 (the cosmonauts
made a safe emergency landing near the Sino-Soviet border).
The back-up crew, Sevastanyov and Pyotr I. Kilmuk, were assigned to
the successful re-flight, also designated Soyuz 18.
