US astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko will return on Wednesday morning for the Earth, after spending nearly a year in orbit aboard the International space station (ISS).
both of them have spent such a long period of time in space as part of the study, how it affects the human body.
on Earth remained enzygotic twin brother, Scott Kelly, and now scientists will be able to compare the condition of his body with an astronaut returning home.
By March 2 mu Kelly and Kornienko will spend 340 days in space. This is a record length of stay on the ISS. This is the fourth flight Kelly into space, where he spent a total of 520 days.
Scott Kelly also bring with them the seeds of arugula with ISS that were left there by the British astronaut Tim Peake in December. The seeds will be distributed to schools, where students will be able to compare how to grow this herbs compared to purely terrestrial
“I could spend a hundred days if it is necessary, and the year -.. It all depends on , what would I do there, and how it should be, “- said Kelly in an interview with the media
But he added that he was glad to go home.. He also called ISS magical place and incredible laboratory.
Scientists want to compare identical twins – one of them returning from a long stay in space – in order to more fully understand how the bodies of two genetically identical individuals react to different environmental
staying in space leads to muscle atrophy, sleep disturbances, loss of bone mass, deterioration. view. Also, astronauts are exposed to radiation. But the most noticeable consequences in space marked in the mind
“Physically I feel very well, -. Says Scott Kelly -. But the most difficult to be in the physical isolation of the people dear to me on earth, because you lose a their relationship “.
” Even after a year here [on the ISS] it is impossible to get used to everything. to live without running water, for example. From the point of view of hygiene, it is like to spend a year in a tent in the woods “.
After Wednesday morning Scott Kelly landed in Kazakhstan, he will fly to Houston, where NASA researchers will begin a full examination astronaut. Only after that Kelly will be able to, as he says, go home and dive into the pool.
His brother, Mark Kelly, the astronaut, was examined at all that year, Scott held on board the ISS.
Comparison of the twin survey will help scientists better understand the often subtle at first glance, physiological and psychological changes, which results in long-term stay in space. According to NASA, it will help prepare the possible flights to Mars
“We learn a lot about the effects of long-duration space flight … I hope that this will be one of the many steps on the way to Mars,” -. Said Scott Kelly.
On Monday, Kelly handed over command of the ISS to his colleague Timothy Kopra. Early Wednesday morning he Kornienko and Russian cosmonaut Sergei Volkov will move aboard “Soyuz”.
The engine “of the Union” will turn on at 03:34 GMT, after which the ship will go towards the Earth. The landing should take place within 53 minutes, at 04:27 GMT (7:27 Moscow time).
The absolute record for the duration of stay in space owned by the Russian cosmonaut Valery Polyakov, who spent 437 days in the mid-90s on board the space station “Mir”.
