In 2013, two hundred thousand people applied for the Mars One project, which wants to send humans to the red planet on a one-way mission. Now there are just 100 people still being considered, and Maggie Duckworth is one of them. She returned to my show to talk about how she's gotten to this point, what's next, and the timeline for the mission. We also discussed "The Martian" movie, in which Matt Damon's character gets left behind on Mars, and whether it changed her mind about wanting to go -- and how her parents reacted, too. I also asked her who she wants to go with, what skills she brings to the mission, and how the funding for the project is going.
