Scientists from Monash University developed a free online Mars survival course that will take about four weeks to complete, with three hours of classes each week. With the rate at which our technology is evolving, coupled with the latest discoveries about possible life on Mars, it’s time we learn the basic sciences needed for humans to survive on the Red Planet. Where’s a good place to begin? How about the online course, “How to Survive on Mars: the Science Behind the Human Exploration of Mars,” offered by Monash University in Australia.
