Stranded and presumed dead on Mars, an astronaut must outwit the planet with his scientific knowledge and a roll of duct tape to survive against impossible odds.
During an EVA on Sol 6 of the Ares 3 mission, a large dust storm threatens the Mars Ascent Vehicle (MAV). Commander Melissa Lewis orders an immediate abort and evacuation. While going to the MAV, debris hits astronaut Mark Watney, a botanist and engineer, impaling him with an antenna. His bio-monitor fails, showing death. Unable to find him in the blinding storm and with the MAV about to tip, Lewis makes the difficult decision to launch, leaving Watney behind, believing him dead. Watney wakes up after the storm, finds the antenna has cauterized his wound, and realizes he is alone on Mars with a damaged habitat (Hab) and limited supplies.
Watney immediately inventories the Hab and his supplies. He calculates his rations will only last about 300 sols, far short of the four years until the next Mars mission, Ares 4, could rescue him. Using his botanical knowledge, he plans to grow potatoes inside the Hab. He turns part of the Hab into a farm, using Martian soil, human waste as fertilizer, and water extracted from leftover MAV hydrazine fuel. This risky plan requires precise calculations and careful resource management, but it is his only hope for long-term survival.
Realizing he needs to contact Earth, Watney remembers the derelict Mars Pathfinder lander, which includes the Sojourner rover, is within driving distance. He plans a journey to the Pathfinder landing site, modifying one of the mission's rovers for extended travel and power. After a dangerous drive, he finds Pathfinder and reactivates its communication systems. He establishes a basic connection with NASA's Jet Propulsion Laboratory (JPL), using its camera to communicate via binary code and then a hexadecimal alphabet. This breakthrough alerts Earth to his survival, starting a global effort to rescue him.
Upon learning Watney is alive, NASA begins rescue efforts, led by Director Teddy Sanders. Mitch Henderson, the Ares 3 flight director, suggests a faster, riskier approach. They develop 'Iris,' an unmanned supply probe meant to reach Mars quickly and resupply Watney. However, due to a rushed launch and poor inspection, a critical bolt fails during ascent, causing the Iris probe to explode shortly after liftoff. This setback forces NASA to re-evaluate their strategy and face intense pressure.
The Ares 3 crew aboard the Hermes spacecraft, returning to Earth, is initially kept unaware of Watney's survival to prevent distraction. However, Mindy Park at satellite imaging detects movement at the Ares 3 landing site, confirming Watney is alive. Eventually, Mitch Henderson informs Commander Lewis and her crew. The news affects them deeply, especially Lewis, who feels responsible for leaving him. The crew struggles with guilt and a desire to help, knowing they are millions of miles away.
After the failure of Iris, NASA is desperate. Rich Purnell, an eccentric astrodynamicist at JPL, develops an unconventional and dangerous maneuver. His plan uses the Hermes's existing trajectory to slingshot around Earth and return to Mars, intercepting Watney with a resupply probe launched from Earth. This 'Rich Purnell Maneuver' would shorten rescue time but risk the Hermes crew's lives, requiring them to stay in space much longer. Director Sanders initially rejects the plan due to the increased risk to five astronauts, but Mitch Henderson secretly leaks the plan to the Hermes crew.
Upon receiving the Rich Purnell Maneuver, Commander Lewis presents it to her crew: Beth Johanssen, Alex Vogel, Chris Beck, and Rick Martinez. Despite the immense personal risk and defying a direct order from NASA, the crew unanimously votes to execute the maneuver. Johanssen, the computer expert, then implements the trajectory changes, effectively taking over the mission. This act forces NASA to support the rescue attempt and launch the necessary supply probe for the Hermes.
To meet the Hermes, Watney must travel over 3,200 kilometers across Mars to the Ares 4 landing site in Schiaparelli crater, where a new MAV is pre-deployed. He modifies his rover for the long journey, adding solar panels, a second battery, and a life support system. The journey is dangerous, with treacherous terrain, equipment failures, and dust storms. He uses his ingenuity to overcome each obstacle, including a critical rollover, relying on his wit and engineering skills to survive the epic trek.
Upon reaching the Ares 4 MAV, Watney receives complex instructions from NASA on how to modify it for his solo ascent and rendezvous with Hermes. This involves stripping down much of the MAV's mass, including the nose cone, seats, and systems, to make it light enough to reach the Hermes's higher orbit. As the launch date nears, a massive dust storm develops, threatening to block the sun and prevent his solar-powered rover from reaching the MAV in time, or even topple the modified MAV itself. Watney races against time and the elements.
Watney successfully launches the stripped-down MAV from Mars, but a miscalculation leaves him slightly off course and short of the Hermes. Commander Lewis, showing great bravery, devises a desperate plan. She uses the Hermes's internal maneuvering thrusters to create a controlled breach, venting air to adjust their trajectory and slow down. She then performs an EVA, using a Manned Maneuvering Unit (MMU) to intercept Watney's MAV, which has been slowed by Watney piercing his own spacesuit glove. Lewis successfully grabs Watney, pulling him to safety aboard the Hermes.
With Watney safely aboard the Hermes, the crew celebrates his survival and their successful, unauthorized rescue mission. The long journey back to Earth begins, filled with relief and camaraderie. Watney, having faced death many times, is finally among his fellow astronauts, no longer alone. The mission, initially a disaster, becomes a story of human ingenuity, resilience, and teamwork. News of his rescue spreads globally, making him a worldwide hero and symbol of hope.
Upon their return to Earth, the Ares 3 crew, especially Watney, are hailed as heroes. Despite the insubordination, NASA largely supports their actions due to public sentiment. Watney, changed by his ordeal, becomes an instructor for astronaut candidates, sharing his experiences and problem-solving skills. He emphasizes teamwork and resourcefulness, inspiring a new generation of space explorers with his story of survival, ensuring his legacy extends beyond just being 'The Martian'.

The novel highlights human ingenuity, showing Mark Watney's ability to solve impossible problems using scientific knowledge and practical skills. From growing potatoes in Martian soil with human waste and water, to reactivating the Pathfinder probe, and modifying a rover for travel across Mars, Watney consistently 'sciences the shit out of' his predicaments. This theme also appears in NASA's efforts, especially Rich Purnell's complex orbital mechanics, demonstrating that human intelligence and creativity are powerful tools against the most challenging environments.
““I'm going to have to science the shit out of this.””
Mark Watney's resilience and strong will to live are central to the story. Despite being alone and facing constant threats of starvation, equipment failure, and the harsh Martian environment, he never gives up. His humor, even in dire situations, helps him cope and shows his mental strength. This theme is clear in his persistent efforts to fix every breakdown, find every solution, and continue his log entries, even when hope seems dim. His refusal to despair inspires both readers and the characters on Earth.
““As with most of life’s problems, this one can be solved by a box of tools and some duct tape.””
The rescue of Mark Watney becomes a global effort, showing the power of international cooperation in a crisis. Initially, NASA is the sole entity, but as the situation develops, China's CNSA offers its booster rocket, the Taiyang Shen, which is key for the Hermes resupply mission. This collaboration crosses political boundaries, emphasizing that humanity can achieve extraordinary feats when united by a common goal. The entire world watches, invested in the fate of 'The Martian,' reinforcing a sense of shared humanity and collective aspiration.
““Every human being has a basic instinct to help each other out. If a hiker gets lost in the mountains, people will coordinate a search. If a train crashes, people will line up to give blood. If an earthquake levels a city, people all over the world will send emergency supplies. This is so fundamentally human that it’s found in every culture without exception.””
The novel explores moral dilemmas, particularly about the value of one life versus many. Director Teddy Sanders' initial rejection of the Rich Purnell Maneuver, prioritizing the safety of the five Hermes crew members over Watney's life, exemplifies this conflict. Conversely, Commander Lewis and her crew's unanimous decision to defy NASA and risk their own lives to save Watney shows selfless sacrifice and the deep bonds within a team. These choices force characters and readers to consider difficult ethical questions about responsibility, loyalty, and duty.
““It's a strange feeling. I'm sure Lewis is beating herself up. She made the right choice. She saved her crew.””
Watney's primary mode of narration and communication.
The story is primarily told through Mark Watney's first-person log entries, which serve as his personal diary and a record of his scientific and engineering challenges. This device provides direct insight into his thoughts, feelings, and problem-solving processes, allowing readers to experience his isolation, humor, and determination firsthand. It also creates dramatic tension as readers learn about his setbacks and triumphs as he experiences them, often with a sarcastic tone that lightens the otherwise dire circumstances. Later, these logs become his communication with NASA.
The relentless ticking of the 'sols' until the next mission or his supplies run out.
The 'sol' count (Martian days) acts as a constant, underlying countdown clock throughout the narrative. It emphasizes the finite nature of Watney's resources and the urgency of both his survival efforts and NASA's rescue plans. Each passing sol highlights the diminishing time and escalating stakes, creating a pervasive sense of suspense. This device effectively communicates the extreme isolation and the scale of time Watney must endure, making his achievements against the clock all the more impressive.
The constant occurrence of unexpected failures and new problems.
Murphy's Law, the principle that 'anything that can go wrong will go wrong,' functions as a recurring plot device, ensuring that Watney faces a continuous series of setbacks despite his meticulous planning. From Hab breaches and equipment failures to dust storms and communication glitches, new problems constantly arise, forcing Watney to adapt and innovate under extreme pressure. This device prevents the narrative from becoming complacent, maintaining high stakes and demonstrating Watney's incredible resilience and problem-solving capabilities in the face of relentless adversity.
Unexpected solutions or interventions that drive the plot forward.
While the book largely emphasizes scientific problem-solving, there are elements that function as 'deus ex machina' to advance the plot when Watney is at his lowest. The discovery of the Pathfinder probe, while scientifically plausible, provides a timely and almost miraculous solution to his communication problem. Similarly, the Hermes crew's defiance of NASA orders to execute the Rich Purnell Maneuver, though rooted in character motivation, acts as an external intervention that shifts the narrative from Watney's solitary struggle to a full-scale rescue, preventing his inevitable demise without a direct solution from his own efforts. These moments provide critical turning points, albeit with some external aid.
