I. Chernykh at the Crimean Astrophysical Observatory. Victor Petrovich Savinykh (b. 1940), a first-class pilot-cosmonaut, was on board the Salyut 6, Salyut 7 and Mir stations. He is a professor and head of the Moscow State University of Geodesy and Cartography, as well as the author of many textbooks, monographs and popular books on science.
