The Martian starring Matt Damon shows us what it might take for a single person to survive on Mars until possible rescue. Without giving away the plot, Matt Damon’s character, Astronaut Mark Watney needs to find a way to grow plants on Mars in order to stay alive and the terraforming he does is pretty accurate.
In the movie, Mark Watney needed to use hydrogen to get the water out of Martian soil in order to water the plants he needed to grow and eat for survival. His big issue was heating the hydrogen without blowing himself up.
