The Soviet and Russian passed away at the age of 81 cosmonaut Valery Poliakov as announced by the state-run Russian Space Agency, Roscosmos. In 1995, he set a record stay in space, in which he remained for 437 days.
Polyakov was sent to the Mir space station in orbit on August 1, 1994 and returned to Earth in late March 1995. Such a long stay in weightlessness is a serious burden on the human body.
Astronauts in microgravity experience loss of bone mass, muscle atrophy, suppression of the immune system. Fluids are redistributed in the body, their vestibular system malfunctions and they develop myopia.
He was a doctor and while in space he researched methods of medical support for long-duration missions
Poliakov was a doctor by profession. Before joining the cosmonaut corps, he worked in the Ministry of Health and in the first aid service. On board he researched methods of medical support for long-duration missions and conducted medical and biological experiments.
Roscosmos claims that Poliakov’s research program proved that the human body lends itself to research in Earth orbit, as well as in deep space.
As reported by the Athens News Agency citing Svoboda.org he was awarded the title of Hero of Russia for the longest mission. For his first mission in 1989 he was awarded the title of Hero of the Soviet Union and the highest Soviet award, the Lenin Prize.
