JPL

Lore & Background

In the world of *The Martian*, JPL is where the rubber meets the orbit. The Ares 3 mission—four astronauts, a six-month transit, and a three-month surface stay—runs through JPL's corridors from the moment the crew boards the Hermes in low Earth orbit. Flight controllers track the trans-Mars injection, the crew's landing at Ares 3, and the abort that strands Watney at the Schiaparelli landing site. When the crew departs without him, JPL's screens go quiet, and the assumption is written into the mission log: one crew member lost.

That assumption shatters when Hubble, pointed back at Mars by a JPL astronomer, picks up the unmistakable geometry of a planted flag and a solar array. The image is grainy, but the silhouette is undeniable. Within hours, JPL Director Mindy Park has convened what the team internally calls the Bermuda group—a cross-section of propulsion engineers, flight dynamics specialists, and systems integrators tasked with the impossible: getting Hermes back to Mars, refueling it from the surface, and pulling Watney out before his supplies run out. The group works in shifts, arguing over delta-v budgets, orbital windows, and the brutal arithmetic of a four-year wait versus a high-risk accelerated plan.

What makes JPL's role resonate with fans is its groundedness. There is no single heroic monologue; there is a room full of people in lab coats, cold coffee, and whiteboard markers, doing the unglamorous math that keeps a stranger alive 225 million kilometers away. The laboratory is a character in its own right—fluorescent-lit, hum-filled, and relentlessly practical.

In Their Own Story

The fluorescent panels in the JPL ops room hum at a frequency that Mindy Park has stopped hearing three years ago. It is 02:47 Pacific. The Hubble frames are still cycling on the main display—Mars, a rust-colored smear, and there, impossibly, a sliver of blue-white that no mission profile accounts for. A flag. A solar panel. A man who should be dead, standing in the dust at Schiaparelli, waving at a telescope that is not a telescope but a camera pointed the wrong way.

She does not cheer. She does not slam the desk. She pulls up the Ares 3 abort timeline, scrolls to the crew's departure burn, and reads the line that says *one crew member not accounted for* as though it were a typo. Then she picks up the phone, dials the NASA administrator, and says, in a voice flat with exhaustion and something that might be fury, "We need to talk about Watney."

Behind her, a junior trajectory engineer is already pulling up the Hermes orbital elements, scratching a number on a sticky note, and muttering, "Four years. Four goddamn years." Mindy Park watches him write it, then writes a smaller number beneath it. The room exhales. The coffee is cold. The whiteboard is waiting.

Reader's Guide

Ares 3 launch and transit: JPL flight controllers manage the trans-Mars injection and monitor the crew's six-month ride aboard Hermes. The stakes are routine—any anomaly could doom the mission—but the team is confident. The turning point is the landing at Ares 3, where a dust storm forces an abort and the crew departs, leaving Watney behind. JPL logs the loss.

Hubble detection: A JPL astronomer, re-pointing Hubble for a routine observation, captures the flag and solar array at Schiaparelli. Mindy Park confirms the image and escalates to NASA HQ. The stakes shift from mourning to problem-solving. The turning point is the decision to convene the Bermuda team rather than file a formal inquest.

Rescue architecture: The Bermuda group, led by JPL propulsion and flight-dynamics engineers, models two paths: a four-year wait for a natural orbital window, or an accelerated plan requiring the Ares 3 surface assets to refuel Hermes. The stakes are Watney's dwindling food and water. The turning point is the choice to attempt the accelerated plan, knowing a single calculation error kills him.

Execution and recovery: JPL coordinates the crew's return to Mars, the propellant transfer, and the final ascent. The stakes are real-time—orbital windows close in minutes. The turning point is Watney's successful rendezvous with Hermes, confirmed by a single telemetry ping that lights up the ops room at 03:12 Pacific.

Did You Know?

• The Hubble Space Telescope, a real NASA/ESA observatory in low Earth orbit, is used in the story to confirm Watney's survival—JPL astronomers have real authority to re-point it for scientific observations.
• The 'Bermuda' team name is a nod to the idea that solving the rescue problem is as mysterious and dangerous as navigating the Bermuda Triangle, a piece of in-universe team culture.
• JPL is a real NASA center operated by Caltech in Pasadena, California, and has been the mission-control hub for actual Mars rover missions like Curiosity and Perseverance, making its role in The Martian feel deliberately
• The accelerated rescue plan in the story requires the Ares 3 crew to return to Mars and use the surface propellant production system to refuel Hermes—a maneuver that, while fictional, is built on real orbital-mechanics c
