In September, at the International Astronautical Congress in Guadalajara, Mexico, SpaceX CEO and founder Elon Musk revealed a grand plan to visit and, eventually, populate Mars. The Q&A session after the event was lacking to say the least, but now, during a Reddit AMA (ask me anything) session late Sunday, Musk shared a number of details about the company's ambitious plans to conquer Mars. This time around, Musk was able to skip the silliness and focus on highly technical aspects of the mission.
