US astronaut completes 1 year in space
March 2 , 2016
US astronaut Scott Kelly and Russian cosmonaut Mikhail Komienko have completed almost a year in space. Their 340-day mission aboard the International Space Station (ISS) has been considered to be twice the length of a normal stay. The extended tour of these two astronauts is part of an effort to study the effects of long-duration spaceflight on the human body. Scientists would be gathering insights on the same by comparing Scott Kelly with his Earthbound identical twin, Mark.
