Astronaut Chris Hadfield on Pluto, music and overcoming fear

Have you ever talked to an astronaut? On Tuesday, you can. The moustachioed Canadian astronaut Chris Hadfield will be in The Stream. He'll shed light on what it's like to live on the International Space Station and record an album while weightless. He'll also discuss a NASA spacecraft's historic flyby of Pluto, the farthest planet from us. Send your questions about life in space and join the conversation at 1930GMT.
