The Martian

The Funniest Survival Story Ever Written

Andy Weir spent years posting The Martian chapter by chapter on his website before a reader suggested he upload it to Amazon for people who wanted to read it on their Kindle. Within days it was a bestseller. Within months, it was a major motion picture starring Matt Damon. Its trajectory from free serial fiction to global phenomenon is one of the stranger publishing stories of the twenty-first century.

The premise is beautifully simple: astronaut Mark Watney is stranded alone on Mars after a dust storm forces his crew to evacuate and they mistakenly believe he died in the storm. He has to survive on limited supplies, no communication with Earth, and no rescue mission for approximately four years.

The Problem-Solving Loop

The novel is essentially a series of problems and solutions, each more challenging than the last. Watney must grow food (he has some potatoes and enough human waste to fertilise them — the chemistry is correct), power his vehicles for the long journey to the only available rescue site, establish communication with Earth (via an old rover and decades-old NASA equipment), and survive the Martian environment while NASA and his crew frantically work to save him.

What makes these sequences thrilling is that Weir actually does the science. The agricultural calculations, the orbital mechanics, the chemistry of the habitat’s life support system — they are substantially correct, which means when Watney finds a solution, the reader can believe in it. And when he misses something and it catastrophically fails, the reader feels that too.

Mark Watney

Watney’s character — established almost entirely through his mission log entries — is one of the most successful protagonists in recent genre fiction. He is brilliant, relentlessly competent, and faces genuine terror with genuine, dark, often hilarious humour. “I’m going to have to science the shit out of this” is a perfect mission statement for both the character and the book.

A Celebration of Science

The book’s deeper theme is a celebration of human scientific and engineering capability. Every person in the novel — Watney on Mars, the NASA engineers on Earth, his crewmates in their orbiting ship — applies specialised knowledge to save one man’s life. The cooperation is improbable, expensive, and ultimately successful. Weir’s vision of humanity using its intelligence collectively to save individuals is both a good story and a genuine moral.

Self-Publishing Origin

Andy Weir worked as a software engineer at AOL when he began posting the chapters of The Martian to his blog in 2009, free of charge. Readers requested an e-book version; he uploaded one to Amazon at the minimum price of ninety-nine cents. It sold 35,000 copies in three months, attracting the attention of agents. Crown Publishers purchased the novel in 2011 for a reported six-figure sum; Random House published the print edition in 2014, and it debuted at number twelve on the New York Times bestseller list.

The Ridley Scott Film

The 2015 film adaptation, directed by Ridley Scott from a screenplay by Drew Goddard, starred Matt Damon as Mark Watney and grossed $630 million worldwide against a production budget of $108 million. The film received seven Academy Award nominations, including Best Picture and Best Actor. NASA provided technical assistance throughout production, and the film’s scenes of Watney farming on Mars drew on actual research into growing crops in Martian soil simulant. Scott described The Martian as his most technically research-intensive production since Black Hawk Down.

Scientific Accuracy

Weir spent approximately three years researching the novel’s technical content before completing the final draft. He consulted with chemical engineers, botanists, materials scientists, and aerospace engineers to ensure that Watney’s problem-solving was plausible given current technology and our knowledge of Martian conditions. The novel’s approach — each chapter presenting a specific engineering problem and its solution — reflects Weir’s software engineering background, in which debugging requires systematic identification and elimination of failure modes. The NASA response to the novel’s release included several blog posts by scientists who verified or gently corrected Weir’s calculations.

Weir’s Scientific Research

Weir’s background as a software engineer at AOL and his years as an amateur scientist gave The Martian its specific character: the pleasure of the novel is the pleasure of problem-solving, of watching a character work through a crisis systematically and find a solution using the materials at hand. Weir researched the actual caloric content of potatoes, the solar panel output that could be generated on Mars, the chemistry of making water from rocket fuel, and the physics of the MAV ascent. He has described the research as the most enjoyable part of writing the novel — the discovery that most of the problems were solvable, given enough ingenuity and patience.

Final Verdict

The Martian is one of the most purely enjoyable science fiction novels ever written. Weir makes you feel the ingenuity, the terror, and the relief with equal intensity.

Our rating: 4.7/5 — The best science fiction debut of the decade. Enormously entertaining and genuinely inspiring about human ingenuity.
