Dzhezkazgan (Kazakhstan) (AFP) – Three astronauts on the International Space Station (ISS), including American Scott Kelly and Russian Mikhail Kornienko who spent almost a year in orbit to conduct experiments for future trips Mars, returned Wednesday on Earth.
around 4:30 GMT, as planned, the Soyuz capsule carrying Russian Sergei Volkov, Mikhail Kornienko and fellow American Scott Kelly, the latter two having spent 340 days aboard the ISS to prepare for future human missions to Mars, arose in the Kazakh steppes southeast of Dzhezkazgan (center).
“the air is so good here. I wonder why you’re all bundled up! “exclaimed Scott Kelly out of the capsule, according to television images of NASA.
So they had to pull themselves out of Soyuz to mimic the conditions of a Mars landing, the astronauts have failed and have received aid evacuation teams to get out, said the Russian control center in the news agency TASS.
Mikhail Kornienko, 55, and Scott Kelly, 52, had arrived on the ISS on March 27, 2015. They have remained almost a year aboard the international space station, the longest uninterrupted period in the last resort since it is able to accommodate passengers in 2000.
During their long stay, the two men have been subjected to regular medical examinations as well as a battery of tests and analyzes to study the long term effects of microgravity on the human body. Samples of body fluids were collected before departure and during the mission and shall be collected for more than a year after their return to Earth.
The twin brother Scott Kelly, former astronaut Mark Kelly, also participated in the ground in the experiment. The data collected on the two brothers should provide accurate and useful points of comparison on the physiological effects of long-term space travel.
At a press conference last Thursday broadcast from the ISS, Scott Kelly had reported feeling well psychologically and that, if necessary, “one hundred days remain more” or more in the confined space of the ISS.
“I could make a year if necessary, “he shouted admitting being” anxious to return “to find his family and friends.
the astronaut was also said to have been affected by lack of water current, which makes it difficult, particularly for personal hygiene
-. ‘camping in the woods’ –
“It’s almost as if I had spent a year to camp in the woods, “he explained. In microgravity, the drops of water floating in the air and in contact with the body, firmly stick to the skin. The astronauts do their toilet with wet sponges.
That’s why Scott Kelly said “the first thing” he would do upon arriving at his home in Houston, Texas, would jump in his pool.
Asked about his health, he had assured to feel “pretty good shape”, with only small vision problems associated with weightlessness. Microgravity indeed increase the cerebrospinal fluid around the optic nerve, affecting vision.
The lack of gravity also well-known effects on the muscles and the skeleton by reducing muscle mass and bone density, forcing the astronauts to exercise regularly.
Sergei Volkov, who took off for the ISS 15 December 2015 and ordered the return flight to Earth, he will have spent . 182 days in orbit
during the mission he has just completed Scott Kelly also beat two American records: one of the longest spaceflight (340 days) and the time combined with 540 days in orbit altogether.
the absolute record for the longest single stay in space returns to Russian Valeri Polyakov, remained more than 14 consecutive months (437 days to be exact) on board the old Mir space station in 1994 and 1995.
the cumulative in orbit time of flight returns to record another Russian cosmonaut Gennady Padalka, who started his last space flight along with Kelly and Kornienko in March 2015 and has a total revolved around the Earth for 879 days.
