Talk with the cast of 'Citizen Mars' during our Facebook Q&A

Would you give up everything you know on Earth to start a new life on Mars and never come back? The five people we profiled in our original series Citizen Mars are willing to do just that for the good of the world. If you've watched our short series, you probably have a lot of unanswered questions for the cast, so we're giving you the opportunity to ask them whatever you'd like in an upcoming Facebook Q&A. On Thursday, September 17th at 11AM PT / 2PM ET, head over to our Facebook page with your questions and get ready for an exciting discussion.

The Citizen Mars series takes an in-depth look at five of the 100 finalists for the Mars One mission. In each episode, we chart progress of everyday people determined to be the first to colonize the red planet.

Through interviews and extensive vérité that spans Europe, Africa, Asia and the US, discover the obsession with the future, adventure and space that's propelling them to leave everything -- and everyone -- behind.
