Astronaut Scott Kelly is returning home after one year and now he is younger than you thought. The study that he is the main member of that was the comparing physical differences between his twins. NASA’s study is really enormous and by looking data, Scott Kelly is younger than his twins. This is called ‘Twin Study’.
Scott Kelly told that “I feel more like an environmentalist since I’ve been up here, there are parts of the Earth that are covered with pollution all the time. I saw weather that was unexpected. Storms bigger than we’ve seen in the past. This is a human effect. This is not a natural phenomenon.”
Staying in space for 342 days may be so hard because the conditions are very different from the earth. Scott Kelly added that “I’ll probably never see it again, I’ve flown in space four times now, so it’s going to be hard in that respect, but I certainly look forward to going back to Earth. I’ve been up here for a really long time and sometimes, when I think about it, I feel like I’ve lived my whole life up here.”
Scott Kelly said that “I plan to be completely honest about it, who knows, maybe there are some crazy thoughts I’ll have at the end that I wouldn’t want to share.”
Kelly had told last year that “You do grow when you’re up there for a long time, unfortunately it doesn’t last.”
I am not sure whether I can do this mission or not. Actually I have no twins however if so I may not do that because I can’t take a chance on spending 1 year. Most particularly I cannot do for a study, it has too risk situation. Some people are very brave and they can do that.
