Astronaut Scott Kelly took this image of himself on the ISS on Feb. 11, 2016 and posted on his twitter account. He wrote, “Day 321 of my #YearInSpace, 500 days in space total.”

NASA's one-year astronaut Scott Kelly, apparently not satisfied merely breaking U.S. spaceflight records on the International Space Station, is about to spin records of a different type today ( Feb. 18) when he steps in as a guest host on NASA's Third Rock Radio during a two-hour web broadcast.

Kelly, who currently commands the space station, will take the helm of the online Third Rock Radio station at 5 p.m. EST (200 GMT) for a special broadcast that "takes the audience inside Kelly's extraordinary #YearInSpace aboard the ISS," NASA officials said in a statement.
