The Martian is about an astronaut who gets stranded on Mars after his crew thinks he is dead. While on a mission,  Mark and his crew encounter a storm that separates them. On their way back to Earth, they find out that he is alive. Mark assimilated to the environment in Mars by using his knowledge of science to help him survive. The next mission to Mars was not for another four years, so he spends his time trying to communicate with them. While in Mars, he extends his food supply by growing potatoes in a planet where nothing grows.  He experiences storms, extremely cold weather and constant failures in his attempts as a botanist. He uses satellites to write to NASA and is successful. Although his chances of survival are minimal, he puts his thinking cap on and convinces them of is plan.  They return to Mars and rescue him. Mark overcomes his displacement and goes back to Earth.
