Hello,
Remember cosmonaut Vladimir Vasyutin in 1985?
He commanded a Salyut 7 crew in 85 and after a while, became fearfull, depressed. He developed a so called "end of the world syndrome" which forced the crew to return back early. The Salyut 7 was left adrift, frozen, but was saved by the next crew (Djanibekov Savinikh) which performed a daring docking with a tumbling station.
Got this on FPSPACE (Stolovski):
On Saturday, on July 20, 2002, passed away from cancer Vasyutin Vladimir
Vladimirovich (born 1952), Russian cosmonaut, pilot-cosmonaut OF THE USSR

chief of the Academy im. Yu.A.Gagarin. Burials will take place tomorrow, on
