Astronaut Scott Kelly Is 2 Inches Taller Now Because SPACE
NASA says having less gravity pressing down on the spine in space actually elongates it.By Ryan Biek | March 3, 2016
In the future, maybe those cursing their lack of height will just spend a year in space.
Astronaut Scott Kelly returned home this week roughly 2 inches taller after spending 340 days on the International Space Station. NASA told CNN it was an expected side effect caused by having less gravity pushing down on discs within the spine.
Earth's gravity will soon bring his height back down, though, so he'll have to gloat as much as he can now to his identical twin, retired astronaut Mark Kelly.
