What Leads Up to the Ending
During a dust storm, Watney is struck by debris and left behind. He has limited food and supplies. NASA discovers he is alive. His crew, led by Commander Lewis, learns the truth and decides to return for him.
What Happens at the End of The Martian
After his Hab airlock blows out and destroys his crops, Watney knows he cannot wait. NASA approves Rich Purnell's plan for the Hermes crew to swing around Earth and back to Mars instead of going home. Watney modifies a rover with solar panels and a makeshift trailer and drives about 3,200 kilometres to Schiaparelli crater, surviving a dust storm and a rollover. To make the Ares 4 ascent vehicle light enough to reach the Hermes, NASA has him strip it, removing the nose cone and covering the hole with Hab canvas. He launches, but the canvas tears and he ends up too low and too slow. Commander Lewis blows a hole in the Hermes to change its speed, and Beck, on a tether, catches Watney. Safe on board, Watney reflects that billions of people helped bring one man home.

Is the Ending Happy or Sad?
Most readers describe the ending of The Martian as triumphant. How you feel about it usually depends on what you hoped for the characters and what you expected Andy Weir to do with the story, so it is worth asking friends how they felt before you compare notes.
Who Will Like This Ending
Readers who enjoy endings that are triumphant will find a lot to talk about here. If you prefer every thread tied up neatly, it helps to know in advance how Andy Weir closes the story, which is exactly why many readers look it up. Either way, the final chapters reward a second look once you know where everything is heading, because small details from the middle of the book start to matter. If you are reading with a group, agree beforehand whether everyone has finished, so nobody has the last chapters spoiled.
Book Versus Adaptation
The 2015 film with Matt Damon follows the ending but adds Watney flying with a punctured suit and an epilogue where he teaches.
Discussion Questions About the Ending
If you are reading The Martian with a book club or a friend, these questions work well once everyone has finished:
- Did the ending surprise you, or had you seen it coming from the first chapters?
- What does the final scene say about survival, and do you agree with Andy Weir's view?
- Which character made the most important choice in the last part of the book, and was it the right one?
- How would the story feel if it had ended one chapter earlier or one chapter later?
- Does the ending leave you hopeful about the characters, or do you worry about what comes next?
- Would you describe the ending as triumphant, or would you choose a different word?
How to Read the Final Chapters Again
- Compare the opening with the close. Look at how the first chapter introduces survival and how the ending answers it.
- Track each final choice. The table above shows where every main character ends up, so ask which of those outcomes was earned.
- Notice what Andy Weir leaves unsaid. Gaps in the last pages are often deliberate, and they are where most of the debate about the ending begins.
- Listen for echoes. Images, phrases or settings from earlier in The Martian often return in the final scene with a new meaning.
Questions to Ask Yourself After Finishing
- Was the ending of The Martian earned by what came before it, or did it feel sudden?
- Which character's final moment affected you most, and why?
- If you could change one thing about the last chapters, what would it be?
- Did the ending change how you think about the opening pages?
