Astronaut Scott Kelly again on the earth After environment document house Flight

American astronaut Scott Kelly, fifty two, is safely back on the earth after spending 340 days in space—a record for an American spaceflight, studies Reuters. Kelly touched down in Kazakhstan at 4:26 a.m. GMT on Wednesday on a capsule carrying two different companions from the international house Station: Russian cosmonaut Mikhail Kornienko, 55, who also spent 340 days in house, and Sergey Volkov, some other Russian cosmonaut, 42, who has been in house for 5 and a 1/2 months.

right through their 340 days in house, Kelly and Kornienko had been the themes of dozens of medical experiments and studies to look how human bodies take care of the lengthy-time period results of weightlessness and publicity to the high-radiation environment of outer house. the consequences of those experiments will likely be used to assist advance manned missions to Mars, which might see astronauts have journeys as long as two years.

sooner than Kelly and his crew took off from the ISS within the landing tablet that would convey them the three-and-a-half of hour journey again to Earth, he snapped an image and posted it on Twitter. “The journey isn’t over,” he wrote. “See you down below!”

That journey also involved more tests once Kelly is again. The American astronaut has an identical twin brother and NASA will learn about the two collectively to peer if Kelly skilled any genetic adjustments all the way through his 340 days in house.

should you’re questioning why Kelly is getting the entire attention for spending 340 days in house and not his cosmonaut colleague Kornienko, it’s because 340 days is the document area flight for an American. Kornienko got here almost 100 days wanting the spaceflight report for a Russian. Between January 1994 to March 1995, Russian doctor and cosmonaut Valeri Polyakov spent 438 days onboard the now-retired Mir area station. Polyakov’s file nonetheless holds for humanity’s longest spaceflight.
