NASA Astronaut Scott Kelly is back from spending 340 days in space, on the ISS, and has grown 2 inches in that period of time.
Kelly's trip to space was part of NASA's "Twin Study", which is a year-long investigation into the subtle changes that may have occurred to Scott Kelly, analyzed in comparison to his twin brother - Mark Kelly - who remained on Earth.
The study is comprised of 10 different investigations in total, but, most obviously, Scott Kelly is now 2 inches taller than his twin brother. NASA's Jeff Williams said, "Astronauts get taller in space as the spine elongates, but they return to preflight height after a short time back on Earth.”
Twin Study is part of NASA's preparation for a crewed mission to Mars, and closely looks at effects on vision, bones and muscles, space radiation, potential shrinking of the heart and the effects that long-term isolation can have on mental health.
