The View From Astronaut Scott Kelly's New Home 200 Miles Above Earth

NASA astronaut Scott Kelly is getting comfortable on the International Space Station, a satellite more than 200 miles above Earth where he will be spending the next year. Kelly is at the very beginning of a yearlong mission during which he'll break the U.S. record for most cumulative time in space, and participate in a groundbreaking study on the effects of space on the human body. Both he and his identical twin brother Mark Kelly, who is a retired astronaut, will undergo close monitoring throughout the year. While Scott is on the ISS, though, Mark will remain firmly on Earth. The study could help NASA prepare for longterm deep-space exploration and even an eventual mission to Mars.
