I. Chernykh at the Crimean Astrophysical Observatory. Russian cosmonaut Sergej Konstantinovich Krikalev (b. 1958) worked aboard the space missions Discovery and Endeavor and was commander of the crews of Mir and the International Space Station. He spent 803 days in space during six flights. He was awarded a special medal by NASA.
