The Martian

In 2035, the crew of the Ares III mission to Mars is exploring Acidalia Planitia on Martian solar day (sol) 18 of their 31-sol expedition. A severe dust storm threatens to topple their Mars Ascent Vehicle (MAV). In the ensuing evacuation, astronaut Mark Watney is struck by debris and presumed dead. With the MAV on the verge of toppling, the remaining crew takes off for their orbiting vessel, the Hermes, leaving Watney behind. Watney awakens after the storm, injured and with a low-oxygen warning. He returns to the crew's surface habitat ("Hab") and treats his wound. As Watney recovers, he begins a video diary. Unable to communicate with Earth, his only chance of rescue is the next Mars mission; in four years, Ares IV will land 3,200 kilometers (2,000 mi) away at the Schiaparelli crater, the Ares IV MAV has already arrived on the site in preparation for the mission.
