What to remember
Launched on 8 January 1994 aboard Soyuz TM-18, Valeri Polyakov did not return to Earth until 22 March 1995, on Soyuz TM-20. In between, he lived aboard the Mir space station for 437 d 16 h 48 min, the longest continuous stay in space by a single person.
A physician, he worked as a space medicine specialist studying the effects of weightlessness. Selected as a cosmonaut in 1972, he had already flown in 1988, launching on Soyuz TM-6 and coming back 240 days later on TM-7. His combined time in space was more than 22 months.
The history shows how stays grew longer: Frank Borman had logged 13 d 18 h 35 min 01 s in 1965, Valeri Rioumine 175 d 0 h 35 min 37 s in 1979 and Vladimir Titov 365 d 22 h 39 min 47 s in 1988. Since 1965 the duration has grown by a ratio of 31.78. The exact figure varies slightly between counts, some giving 437 days and 18 hours.
