The movie "The Martian," directed by Ridley Scott and starring Matt Damon, hits theaters this Friday. It's a big-budget Hollywood production about an astronaut stranded on Mars using his wits to survive. But this man-versus-nature epic has a surprisingly humble origin. It was initially published online for free by computer programmer Andy Weir, who used his computer design background and the combined knowledge of his readers to write what might be the most scientifically detailed novel about space travel.
After offering "The Martian" as a free web serial online, Weir was met with a demand for an easier way to access the his writing on e-readers. So he listed his book for the cheapest price available on Amazon: 99 cents. The publication quickly became a best-seller on the site. Soon, Weir sealed a print deal with Random House and a film deal with Twentieth Century Fox.
During the writing process, Weir wanted to make his story as realistic as possible. An experienced computer programmer, he built his own computer simulation of the orbital trajectory. But there were also places in the story where he sacrificed accuracy for drama. In the beginning of the book, for example, the protagonist confronts a sandstorm on Mars. In reality, that would feel like "somebody blowing on you on Earth," Weir explains.
But in a man-versus-nature story, Weir wanted "nature to get the first punch."
