From the International Space Station, NASA astronaut Scott Kelly (stationcdrkelly on Instagram) took this photograph and posted it to social media on April 6, 2015. Kelly wrote, "Australia. You are very beautiful. Thank you for being there to brighten our day. #YearInSpace"Kelly and Russian Federal Space Agency (Roscosmos) cosmonaut Mikhail Kornienko began their one-year mission aboard the space station on March 27. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight.Image Credit: NASA
