For those who are fans of the Canadian Astronaut Chris Hadfield, once commander of the International Space Station, he will be on TV show StarTalk.
This is the new show spun off from the radio show of same name hosted by Astrophysicist, Neil Degrasse Tyson on the National geographic channel.
The show just started recently and he has had some very engaging guests.
