It's a pretty crazy/brilliant plan. endobj The basic strategy of the Rich Purnell maneuver is not fictional—a crippled Japanese Mars probe named Nozomi actually used a similar Earth-flyby scheme to set up a second chance for its own faltering unmanned Mars mission a dozen years ago."

It turns out that those unlikely reserves are critical to pulling off the "Rich Purnell maneuver," a daredevil rescue of Watney spearheaded by one of Weir's characters, a genius, socially awkward NASA mission designer of the same name. The Martian (2015) - Yarn is the best way to find video clips by quote. As Hermes flew by Earth, it then resupplied for the extended voyage to Mars from a supply craft launched using the Chinese rocket booster originally intended for the Taiyang Shen. Get a gravity assist of Earth, resupply Hermes while on an escape trajectory, and get a trajectory back to Duna. Instead of Hermes executing its planned month-long deceleration to enter low Earth orbit (LEO), Hermes instead began accelerating again using its ion engines to increase its momentum further to perform a flyby of Earth, using Earth's gravity to perform a gravity assist and increase its momentum further. The Rich Purnell Maneuver is a fictional orbital trajectory from the book and film “The Martian”.
