The famous Valeri Vladimirovich Polyakov is a Russian former cosmonaut. He is the holder of the record 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 is more than 22 months.
Polyakov volunteered for his 437-day flight to learn how the human body would respond to the micro-gravity environment on long-duration missions to Mars.
Upon returning from his second spaceflight, Polyakov held the record for the most total time in space. This record was later broken by Sergei Avdeyev and is currently held by Gennady Padalka.
Data from Polyakov’s flight has been used by researchers to determine that humans can maintain a healthy mental state during long-duration spaceflight just as they would on Earth.
Polyakov underwent medical assessments before, during, and after the flight. He also underwent two follow-up examinations six months after returning to Earth.
When researchers compared the results of these medical exams, it was revealed that although there were no impairments of cognitive functions, Polyakov experienced a clear decline in mood as well as a feeling of increased workload during the first few weeks of spaceflight and return to Earth.
Polyakov’s mood stabilized to pre-flight levels between the second and fourteenth month of his mission. It was also revealed that Polyakov did not suffer from any prolonged performance impairments after returning to Earth.
In light of these findings, researchers concluded that a stable mood and overall function could be maintained during extended duration spaceflights, such as crewed missions to Mars.
