Scott Kelly arrives home after almost a year in space and this has given scientists a unique situation for making comparisons because Kelly has an identical twin here on Earth. Tests performed on Scott Kelly after living in a weightlessness environment for a year will be compared to Mark Kelly, who is a retired astronaut and Scott’s identical twin. While Scott spent 340 days on the ISS, Mark spent the same year with his feet firmly planted on the ground back on Earth.
MSN News reports on March 3 that Scott Kelly’s accomplished career now has a year as an ISS resident to add to an extremely impressive resume. While landing back on Earth is an event filled with joy for Scott and his family, he has some recuperating to do after a year in this totally different environment.
Muscle and bone deterioration along with his vision are things that will take some time to go back to normal. Kelly has made history as spending the most time in space out of all the U.S. astronauts. Comparing Scott after his long stay in space with his identical twin, who lived under normal conditions on Earth, should offer NASA scientists a unique perspective of the effects long periods of time in space have on the human body.
Kelly has grown 2 inches and has gotten slightly younger because time goes slower in space, reports “Fox and Friends” live on Thursday morning. NASA’s Jeff Williams said Scott Kelly “grew two inches during his time aboard the International Space Station,” but Kelly getting taller was expected and it is only temporary, reports ABC Local News.
The Kelly twins are 52 and when Scott left Earth 340 days ago, he was the same height as his brother. Mark volunteered to be part of NASA’s “Twins Study” as a retired NASA astronaut when his brother Scott signed on for the 340 day space mission.
The taller version of Scott is something that goes along with being in space for a good chunk of time. Williams said, “Astronauts get taller in space as the spine elongates. But they return to preflight height after a short time back on Earth.” The many tests that both Scott and Mark will undergo, should offer a treasure trove of scientific information for the NASA scientists.
Missing his loved ones was the hardest part of living in space for 340 days, said Scott when touching back down on Earth. He was surprised at how wonderful that cool blast of fresh air felt upon opening up the capsule’s door when arriving back on the planet. One thing that didn’t wane during that long stay in space was his ability to hit the social media with a few “I am home” tweets!
