Who has been in space the longest?

(ORDO NEWS) — The popular Japanese magazine “Shukan Gendai” in the “Science 365 Days” section writes that, among other achievements in space, Russia also holds the lead in the stay of its cosmonauts in space orbit.

On August 1, Russian cosmonaut Valery Polyakov left for the ISS Mir, where he spent 437 days, 17 hours and 58 minutes. Polyakov was born in 1942 near Tula, received a medical education and in Russian space programs was actively involved in the study of the effect of weightlessness and being in space on the human body.

Valery Polyakov made his first flight into space in 1988. Then he was in orbit for 240 days 22 hours and 34 minutes.

A physician by training, Polyakov made a great contribution to the study of the effects of space on humans. His research programs were aimed at proving the possibility of carrying out long-term manned flights on spacecraft, including to Mars. He created special programs for training muscles, joints and maintaining all the main systems of the human body in working order under conditions of weightlessness and exposure to cosmic radiation. A separate remarkable line in the work of the Russian researcher is the development by him of special rations of space nutrition, which allow astronauts to maintain their strength and efficiency during a long stay in orbit. In 1999 he became a Doctor of Science and Professor of Medicine.

“Shukan Gendai” especially notes that Polyakov’s 1994 record for the duration of an orbital flight has not yet been surpassed by anyone.

Another Russian cosmonaut, Gennady Padalka, set a record for the total duration of stay in space for several flights. Its total space flight time is 878 days in 5 flights – almost three years in space.

The publication says that of the Japanese astronauts, Koichi Wakata was the longest in space. In total, he made 4 long orbital flights on American and Russian spacecraft. The total duration of his stay in space is 347 days 08 hours 30 minutes. In 2014, as the commander of the ISS-39 expedition, he spent 187 days in space. Wakata was the first Japanese commander on the ISS. Then its delivery to the ISS and return to Earth was carried out by the Russian Soyuz TMA-11M launch vehicle.

In 2017, Vakata wrote the book “The value of a person is determined by his labor”, in which he found warm words to the Russian cosmonautics and Russian experts in space exploration. In 2006-2007, Wakata underwent pre-flight training at the Cosmonaut Training Center. YA Gagarin and received the qualification “flight engineer”. In the book, Wakata explains to readers the meaning of the Russian word “mir”, which was used to refer to the Russian ISS.

The publication of “Shukan Gendai” attracted interested responses from readers. “Such astronauts are just heroes,” writes one of them. – How can a person withstand such a time in a limited space and weightlessness! There is a place for exceptional people! ”

“After all, a long stay in space has a bad effect on the human body, especially on the heart. Therefore, it is good that the cosmonaut-doctor was engaged in special research here. This is especially valuable! ” Another exclaims. “And yet, we should think about how, in possible cases, assign the functions of astronauts to robots. True, so far this is hardly possible! ” – the third shares his opinion.
