HONG KONG: Scott Kelly has been in space for 172 days. Right now, as you read these words, he’s orbiting Earth in the International Space Station, as a participant in the first international One Year Mission with cosmonaut Mikhail Kornienko — the goal of which is to study the effects of life in space on the human body in a slew of experiments.
Scott’s identical twin brother, fellow astronaut, and former NASA Commander Mark has been living comfortably on Earth during that same time. Since Mark and Scott are the same age, same fitness level, and have identical genetics, they make the perfect test subjects for studies on human physiology, behavioral health, microbiome and molecular continuity. They form the center of NASA’s Twin Study.
On Tuesday, September 15, 2015 C-SPAN2 aired a National Press Club discussion. Mark Kelly talked about the ongoing research and his brother fielded questions from the ISS via video link.
John Hughes, National Press Club President asked Scott how he was doing: “How do you feel, what effects have microgravity had on you so far during this almost six month period?”
Scott said, “As far as physically, I feel good, we have some pretty good exercise equipment up here, but there are a lot of effects of this environment that we can’t see or feel, bone loss, effects on our vision, our genetics, DNA, RNA and proteins, and that’s why we’re studying this.”
