Rich Purnell's Office
One whiteboard, one scribbled maneuver, one Martian breathing again.
via Wikipedia: The Martian (Weir novel) · see source
Whiteboards dense with equations. Stacks of technical papers on every surface. This is the Jet Propulsion Laboratory office of the astrodynamicist who cooked up the 'Rich Purnell Maneuver' in Andy Weir's The Martian — the rescue plan that gets Mark Watney off Mars. No task force, no briefing room. Just one cluttered desk, one guy grinding through the math until the numbers finally said yes. It's the quiet, cerebral engine of NASA's problem-solving: a single scientist's insight deciding whether an astronaut stranded on Mars comes home.

Lore & Background
Rich Purnell is a NASA astrodynamicist. In the novel, he devises a 'slingshot' trajectory around Earth for a gravity assist that could get Hermes back to Mars on a much-extended mission to save Watney, using the Chinese rocket booster to send a simpler resupply probe to Hermes as it passes Earth. This plan is called the 'Rich Purnell Maneuver.' NASA Administrator Teddy Sanders vetoes the maneuver, as it would entail risking the other crewmembers, but Mitch Henderson, the Ares 3 flight director, secretly emails the details to Hermes. All five of Watney's crewmates approve the plan. Once they begin the maneuver, having disabled the remote overrides, NASA has no choice but to support them. The resupply ship docks with Hermes successfully. Purnell's office is not, but his role is central: he is the astrodynamicist whose calculations make the rescue possible.
Reader's Guide
Rich Purnell's office is a compact, academic workspace at NASA's Jet Propulsion Laboratory in Pasadena, California. It serves as the creative and analytical hub for the Rich Purnell Maneuver, the gravitational slingshot plan that rescues Mark Watney from Mars. In the story, this office is where Purnell works alone, crunching numbers and refining his proposal before presenting it to NASA leadership. Its role is crucial: it's the birthplace of the mission's most daring element, highlighting the importance of individual expertise within a large organization. The office matters because it symbolizes the quiet, often overlooked contributions that make space exploration possible—a reminder that breakthroughs can come from a single desk, not just a control room.
