Astronauts live 1 year on the universe to Earth safely

On March 2, astronaut Scott Kelly (USA) and Mikhail Kornienko (Russia) safely returned to Earth after nearly a year of living on the universe.

In total, these two astronauts worked on the International Space Station (ISS) 340 days - twice the time of other astronauts' station time in conventional space missions.

Their long stay on the station helped to study the effects of long-term space flights on the human body.

As for Scott Kelly, scientists can study more in depth when comparing his health and psychological status with twins on Earth, former astronaut Mark Kelly.

This research is intended to pave the way for people to go to Mars someday.

According to scientists, the harsh environment in the universe can cause muscle atrophy, insomnia, osteoporosis, vision loss . But the most obvious effect is psychological.

Before landing at Kazakhstan at noon two days, Scott Kelly said he felt quite physically well, but felt isolated from the people on Earth, in other words he felt "disconnected". .

Now this astronaut is being taken to Houston, USA to start a series of scientific tests.

Although 340 days in space, Scott Kelly is not the person who has the longest flight time. This record still belongs to Russian astronaut Valery Polyakov, who spent 437 days on space station Mir in the mid-1990s.
