Stretched Spaceman Scott Kelly Shrinks Again

Astronaut Scott Kelly has shrunk back to his normal height after growing by 1.5 inches while on the International Space Station, his identical twin brother has said. His 340 days aboard the ISS allowed NASA to study the long-term effects of space travel using a comparison between his development and that of his twin brother Mark on Earth. Once back on Earth, Commander Kelly shrank back to normal within two days.
