Valeri Polyakov, record-breaking cosmonaut, dies at age 80


When people lastly tread the ochre-hued plains of Mars for the primary time, one may look up on the heavy, dust-laden skies and tender a wordless word of due to cosmonaut Valeri Polyakov, who helped pave the way in which. Polyakov died Monday, Sept. 19, 2022, at age 80.

Valeri Polyakov is understood for finishing up the longest single spaceflight in historical past, spending 437 days straight on the Mir space station between 1994 and 1995. And over the course of his two-mission profession, Polyakov logged practically sufficient day without work Earth’s floor to finish a theoretical round-trip to the Red Planet and again.

The priceless classes we discovered from Polyakov’s prolonged spaceflights haven’t solely helped us defend the handfuls of astronauts which have since orbited Earth. They additionally may set the stage for what sometime may very well be humanity’s biggest achievement: venturing to a planet past our personal.

A more in-depth have a look at Valeri Polyakov

Valeri Polyakov’s title is now within the file books. But this extroverted, bodily imposing bear of a person entered the world with a distinct title. Valeri Ivanovich Korshunov was born April 27, 1942, within the industrial metropolis of Tula, situated roughly 110 miles (180 km) south of Moscow. At age 15, nevertheless, he modified his center patronymic and household title to Vladimirovich Polyakov in honor of his adoptive stepfather.

Polyakov initially studied drugs in Moscow, specializing in astronautical drugs on the capital’s Institute of Medical and Biological Problems. He went on to change into a Soviet cosmonaut in 1972 — although his look forward to an precise spaceflight proved lengthy and arduous.

Finally, on August 29, 1988, Polyakov launched to the Mir space station aboard Soyuz TM-6, accompanied by fellow cosmonaut Vladimir Lyakhov and Afghanistan’s first spaceman, Abdul Ahad Momand. His crewmates returned to Earth’s floor every week later, however Polyakov remained on Mir to supervise the well being of Vladimir Titov and Musa Manarov, two cosmonauts who have been nearing the conclusion of the world’s first year-long spaceflight. Titov and Manarov returned to Earth in December 1988, however Polyakov remained aboard Mir to welcome two new crewmates.

Polyakov in the end didn’t return to Earth till April 27, 1989. With a length of 241 days, the cosmonaut’s first mission ranked because the third-longest spaceflight on the time. But Polyakov’s subsequent mission could be longer nonetheless.

Medically minded cosmonaut

By the late Eighties, Russia had decisively pushed the envelope of long-term spaceflights. Yet the consequences of microgravity upon the human physique remained imperfectly understood. Cosmonaut Yuri Romanenko, who flew for 326 days in 1987, discovered himself working much less, sleeping extra, and exercising vigorously as his mission approached its finish. Longer flights, mission planners realized, demanded shut medical supervision of the crew. And higher but, they demanded a medical skilled on the crew.

Polyakov was one such skilled. In 1993, he volunteered to be stationed on Mir for 18 months. But his deliberate November launch aboard Soyuz TM-18 was delayed till January 8, 1994. And with plans for NASA’s space shuttle to go to Mir in mid-1995, Polyakov’s mission was additional reduce, first to 16 months, then to 14 months.

Joining Polyakov on Mir for the primary six months of his off-world marathon have been Viktor Afanasyev and Yuri Usachev. Between July 1994 and March 1995, they have been changed by three rotating crews of cosmonauts and astronauts from Russia, Kazakhstan, Germany, and the United States.

While aboard Mir, Polyakov supported 25 life sciences investigations, which emphasised weight loss program, the human muscular system, the lungs and immune system, the blood and central nervous system, and the balance-regulating function of the inside ear.

Early in 1995 — quietly and with out fanfare — Polyakov’s mission surpassed Titov and Manarov’s file of a yr in orbit. But by now, the top of Polyakov’s spaceflight glinted like a mirage on the horizon.

In February 1995, Space Shuttle Discovery drew to inside 30 toes (9 meters) of Mir, photographing a beaming Polyakov at one of many station’s home windows. A number of weeks later, Norm Thagard joined Polyakov on Mir, changing into the primary U.S. occupant of the Russian space station.
