Books like The Martian

Andy Weir's own Project Hail Mary follows Ryland Grace, who wakes up alone on a spaceship with no memory and gradually pieces together that he is Earth's last chance to stop an alien microbe from dimming the sun. The humor, the science-first problem-solving, and the lone-protagonist-against-the-void structure all carry directly over from The Martian, but Weir adds an alien friendship that gives the story emotional dimensions his debut did not attempt.

Grace approaches each crisis the same way Watney does: break the problem into smaller problems, apply the relevant science, and crack jokes to keep the panic at bay. The space travel physics feel rigorous without becoming lectures, and Weir paces the reveals about Grace's past to create a mystery alongside the survival plot.

The alien Rocky communicates through musical tones, and the scenes where Grace and Rocky work together to solve engineering challenges rank among the most inventive and heartwarming in recent sci-fi. If you loved The Martian's tone, this is the closest you will get to recapturing that reading experience, with a wider scope and more emotional range.

Weir's second novel moves the setting from Mars to the moon, following Jazz Bashara, a smuggler living in humanity's first lunar city who gets pulled into a conspiracy that threatens the entire settlement. The tone shares The Martian's wisecracking narrator and technical detail, though Jazz is a more morally complicated protagonist than Watney. Weir builds the lunar economy with the same engineering mindset he brings to survival scenarios, showing how welding, EVA suits, and air recycling work in one-sixth gravity.

The heist plot gives the book a different shape from The Martian's survival structure, adding crime fiction momentum to the hard sci-fi foundation. Jazz's voice runs sharper and more cynical than Watney's earnest optimism, which gives the novel a distinct personality while keeping Weir's signature readability. The worldbuilding details about how a lunar city actually functions, from its oxygen supply to its economic incentives, scratch the same itch as The Martian's agricultural calculations.

This suits readers who want The Martian's scientific rigor applied to a more plot-driven, action-oriented story set on a different celestial body.

Martha Wells's novella introduces Murderbot, a self-aware security android who has hacked its own governing module and would rather watch soap operas than protect humans. The voice is the strongest link to The Martian: both Murderbot and Watney use sardonic humor to cope with dangerous situations, and both narrate their survival with a running commentary that makes technical problem-solving entertaining. At under 200 pages, the story is tight and propulsive, following Murderbot as it investigates a mysterious threat to the planetary survey team it is supposed to be protecting.

Wells writes action sequences with clarity and her worldbuilding reveals itself through Murderbot's practical observations rather than exposition dumps. Like The Martian, the book treats competence as the most appealing character trait, giving readers a protagonist whose expertise is the primary tool for solving every problem. The series that follows expands Murderbot's world significantly, but this first installment works as a perfect standalone.

For readers who loved Watney's voice and want a similarly entertaining narrator in a faster, more compact format, All Systems Red delivers exactly that.

Becky Chambers's debut follows the crew of a tunneling ship that creates wormholes through space, focusing on the interpersonal dynamics of a ragtag group of humans and aliens rather than any single crisis. The connection to The Martian is tonal: both books create a warm, hopeful vision of humanity's future in space, and both use humor to keep the stakes from becoming oppressive. Where Weir's humor comes from one man's wisecracks, Chambers generates hers from the friction and affection between crew members with wildly different cultural backgrounds.

The worldbuilding prioritizes alien biology and culture over hardware specifications, giving the book a different flavor of specificity from The Martian's engineering focus. Chambers writes found family dynamics with genuine warmth, making the ship feel like a place you want to spend time. The plot is more character-driven and episodic than The Martian's survival sprint, rewarding readers who want to sink into a world rather than race through it.

This suits readers who loved The Martian's optimism about people working together and want that quality expanded to an entire crew, with the tension turned down and the emotional bandwidth turned up.

Neal Stephenson's Seveneves opens with the moon exploding and follows humanity's desperate two-year scramble to launch enough people into orbit to survive the rain of meteorites that will sterilize Earth's surface. The hard science credentials match The Martian's, with Stephenson spending pages on orbital mechanics, genetics, and spacecraft engineering that feel researched down to the last bolt. Where Weir focuses on one man's survival, Stephenson tracks an entire civilization's attempt to cheat extinction, giving the story an epic scale that The Martian never attempts.

The first two-thirds of the book carry the same addictive quality of watching smart people solve terrifying problems under impossible deadlines. Stephenson's prose is denser than Weir's punchy style, and the book runs over 800 pages, so readers should expect a bigger time investment. The final section jumps forward five thousand years and reimagines human society from the ground up, which divides readers but rewards those who enjoy speculative worldbuilding pushed to its limits.

For fans of The Martian who want the same scientific rigor applied to a much bigger canvas, this is the next step up.

Kim Stanley Robinson's Red Mars drops the first hundred colonists on Mars with orders to terraform the planet, then follows the scientific, political, and personal conflicts that erupt as they try to turn a dead world into a living one. The Mars setting connects directly to The Martian, but where Weir tells a survival story, Robinson writes a civilization-building epic that spans decades and hundreds of characters. The science is impeccable, covering areology, atmospheric engineering, and genetic modification with a depth that makes The Martian's botany experiments look like a warmup.

Robinson treats the political arguments about how to settle Mars with the same seriousness he gives the technical ones, creating a book that functions as both hard sci-fi and political novel. The pacing is slower and more deliberate than Weir's thriller momentum, requiring patience from readers used to The Martian's relentless forward motion. The payoff is a portrait of Mars so detailed it feels like a place you could visit.

This is for readers who loved the Mars setting and want to see what happens after the rescue ship arrives and the real work of living on another planet begins.

Douglas Adams's comedy classic follows Arthur Dent, the last surviving Earthling, as he hitchhikes across a universe that is absurd, bureaucratic, and deeply unconcerned with his wellbeing. The link to The Martian is the humor: both books find comedy in a protagonist who is completely out of his depth in space, though Adams pushes the absurdity far beyond anything Weir attempts. Where Watney uses science to solve problems, Arthur stumbles through crises aided by a perpetually depressed robot, a two-headed galactic president, and a book that is more popular than the Bible.

Adams writes with a wit and verbal inventiveness that makes every sentence a potential punchline, and his satire of bureaucracy, technology, and human self-importance still lands decades after publication. The science in this book is entirely fictional and played for laughs, so readers expecting The Martian's technical rigor should adjust their expectations. What carries over is the experience of reading a space novel that genuinely makes you laugh out loud, something far rarer than it should be.

This pick is for readers who want The Martian's comedic sensibility untethered from realistic physics and turned loose on the entire universe.
