America, Russia choose people who work as

The two astronauts will fly to the International Space Station (ISS) in 2015 and live there for one year, the longest working time of humans in the station's history.

Russian Federal Space Agency (Roscosmos) announced yesterday that two astronauts Mikhail Korniyenko (Russia) and Scott Kelly (USA) will fly to ISS with Russian Soyuz in 2015, the AP reported. This is the first astronaut pair to work on ISS for 12 months.

Scott Kelly, an American astronaut who served as a naval fighter pilot, believes his 2015 flight is of great significance for the future of the space industry.

"The goal of a one-year flight is to test the reactions of the human body and our ability to adapt to the harsh conditions in the universe. It will help us reduce the risk in those flight to the moon's orbit, meteors and even Mars " , Roscosmos said.

Korniyenko and Kelly used to work on ISS for 6 months as an engineer in 2010. The US Aerospace Agency (NASA) wants to select astronauts who once lived on ISS to reduce the time spent practicing for flight. a year. So they only consider a few candidates. The training of two people will start from next year.

ABC News commented that, with the life in orbit for a year, the role of Korniyenko and Kelly would be identical to the "white mice" in scientific experiments.

Currently the maximum working time of each astronaut on ISS is 6 months. Doctors worrying about the weightless environment will adversely affect astronauts' eyesight, bones and cardiovascular system if they live too long in space.

Vladimir Popovkin, director of Roscosmos, revealed that selecting astronauts for flight is difficult. NASA and Roscosmos finally decided to choose those with the highest sense of responsibility. According to him, Korniyenko and Kelly are the two most passionate about work on ISS.

This will be the longest space flight conducted by an American astronaut. The longest flying record in space belongs to Valery Polyakov, a Russian astronaut. He worked in Russia's Mir space station in 438 days from 1994 to 1995. Michael Lopez-Alegria is the longest US astronaut in the universe. The astronaut worked on ISS for 215 days in 2006 and 2007.
