The astronaut Scott Kelly, the American who more time has remained in a mission on the International Space Station (ISS), grew 5 centimeters in less than a year, according to local media reported today.
backbone of Kelly, who returned on Wednesday this week to Earth, after successfully completing the space mission was extended by the lack of gravity.
on Earth, the gravitational force compresses the bones but in outer space, its absence allows expansion of the discs of the spine, as related by CNBC. However, after a few hours of returning to Earth, Kelly recovered its original form and was again exactly as tall as his twin brother, Mark, a retired astronaut, as confirmed by CNN with the brothers.
the astronaut was in space for 340 days with the aim of studying the physiological changes that the human body experiences in space.
the findings will be applied in future exploration missions of the Universe, especially in possible expeditions Mars, said yesterday the head of NASA, Charles Borden, and the director of the Office of Science and Technology of the White House, John Holdren.
Kelly, 52, participates with his brother twin ten research on human psychology, health, microbiology and molecular study in which data are compared one another in space and on Earth.
