What Happens, Part by Part (Contains Spoilers)
Stranded
On sol six of the Ares 3 mission, a severe dust storm forces the crew to evacuate. Watney is struck by debris, and his suit's signal fails. Commander Lewis is forced to leave without him. Watney wakes up alone, with no way to contact Earth.
Survival
Watney calculates that he has food for about a year but must survive four years until the next mission. He grows potatoes in the Hab using Martian soil, crew waste and water he makes from rocket fuel, nearly blowing himself up.
Contact
NASA's Mindy Park notices changes in satellite images and realizes Watney is alive. Watney drives to the old Pathfinder probe and uses it to communicate with Earth by a hexadecimal code. The world follows his story.
Setbacks
The Hab's airlock fails, killing his crops. NASA rushes a resupply probe, which fails on launch. Rich Purnell proposes sending the crew's ship, Hermes, back to Mars on a slingshot route. China provides a booster. The crew agrees, defying NASA.
The ending
Watney drives about 3,200 kilometers across Mars to the Schiaparelli crater, where a launch vehicle waits for the next mission. He strips it to make it light enough to reach orbit. Lewis performs a daring spacewalk and catches him. Watney returns home, reflecting that people help each other.
5 Key Takeaways
