This is the second part of my interview with Christian Knudsen, a Mars One candidate to make a one way voyage to Mars. Because of that experience, Christian understands the nuances of space flight better than most. He describes in this episode the issues to be dealt with in making a 6-8 month trip to Mars, the psychology, the health risks, and the issues of landing safely and setting up a colony. He also describes details of terraforming Mars for a comfortable human presence.

This is very fascinating stuff and you will learn a lot about what it takes to get to Mars.
