Mark and Scott Kelly are the only twins who have ventured into space, and they have on some level ‘given’ their bodies to science to help us understand how space affects our DNA and so much more.
The Verge, one of our favorite tech sites, had an interview with these twins after some interesting data has been released from NASA after Scott spent 340 consecutive days in space between 2015 – 2016. The results have already shown how Scott’s DNA has change from his trip. It’s so interesting to see how our environment plays into our lives on a very base level. It just goes to show you that we’re all connected.
