I have not seen the movie version of The Martian but the novel was one of the best sci-fi books I've read in years. Heavily researched and based on a lot of real science, this is the story of Mark Watney who, through a serious of impossible to predict circumstances, is left behind on Mars. Luckily he has a fully functional Hab research/living space, two rovers, six space suits, a bag of potatoes and a very good sense of humor. Mark tackles the challenge of surviving on Mars with a can-do attitude and huge amount of ingenuity.
