Do you remember watching Total Recall and thinking, "we'll never live on Mars." Well, we might not, but that doesn't mean that humans won't. In fact, we're probably a lot closer to making it happen than you think. Our friends at SpaceX think they will be sending humans to Mars in just 6 years, and NASA is planning on doing so in under 20.

All that being said, what is it going to take to make Mars habitable? And what technology needs to be in place to get us there? Of course we've summed it all up in just over 30 minutes for your listening pleasure!
