Space, the three astronauts on the ISS Soyuz arrive – The Republic

MOSCOW – It took off at 22:42 Moscow time (20:42 to Italian), from the Baikonur Cosmodrome in Kazakhstan, the Soyuz capsule that brought on the Station International Space (ISS), NASA astronaut Scott Kelly retired (51 years) and Russian cosmonauts Mikhail Kornienko (54 years) and Gennady Padalka (56 years).

It ‘the first mission lasting one year ever organized by NASA and meant to pave the way for long journeys to Mars. The changes that will occur in the absence of weight on Scott Kelly will be compared with those of identical twin Mark, who remains on Earth. Waiting for them on the Space Station astronaut Samantha Cristoforetti.

For a year all the physiological parameters of Scott and Mark Kelly will be compared and, as they are identical twins have the same DNA therefore, the results will finally have a better idea of ​​the effects on the human body of long periods spent in zero gravity. Are valuable knowledge to protect astronauts in the future will address the long space voyages direct to the Moon or Mars.

The twin in space and the other is left to Earth immediately suggest the twin paradox created by Albert Einstein to explain the theory of relativity. Under this point of view, however, the effects will not be at all obvious as Scott, in his stay in orbit, it will be younger than Mark only three milliseconds.

On the Space Station will stop for a year also Kormienko while the rest of the crew will continue to alternate with traditional rounds of six months. Aboard the Space Station, which will reach in six hours, await, with Samantha Cristoforetti, Commander Terry Virts and Russian Anton Shkaplerov.

As for Kelly and Kornienko, there will set any records, because the record of consecutive days in space belongs to the Russian Valeri Poliakov, who spent 437 on the Russian station Mir between 1994 and 1995. The three astronauts parties today will join the crew that currently occupies the ISS: the Italian Samantha Cristoforetti, Russian Anton Shkaplerov and the American Terry Virts.
