Josh Richards isn't your run-of-the-mill comedian, astronaut or engineer. Or soldier for that matter. The 32-year-old Australian has committed himself to all types of work over the years, but for the last five has been devoted to becoming one of the four humans to be sent to Mars in 2024. For good. He's made it to the last 100 candidates, and Nicole had all sorts of questions she wanted to throw his way – What did his family say? Is he sure he wants to go through with it? How does he approach relationships knowing that one day he could be living on a different planet? Josh's ability to think of his species rather than himself is commendable and inspiring.
