Question
Which Russian Cosmonaut holds the record for the
longest spaceflight overall?Solution
Valeri Vladimirovich Polyakov was a Soviet and Russian cosmonaut. He is the record holder for the longest single stay in space, staying aboard the Mir space station for more than 14 months during one trip. His combined space experience was more than 22 months (437 days in the mid-1990s). Initially it was thought the mission would be six months long, but the spacecraft he was aboard began leaking coolant and NASA said it couldn't make a normal return to Earth.
