with the statement that he does not think Rich Purnell is \six times more likely to work" (page 206). Hi, this is great thanks. The author- Andy Weir in many talks and interviews, mentions that it needs a ion engine in the space ship. Hello there fellow Kerbalnaughts I have been recently challenged by a friend of mine to recreate the rescue mission from the film The Martian and I'm after any information that can help me set perameters. Unfortunately they don’t actually reference the trajectory parameters except incidentially, but it does have some interesting discussion. However, Mitch secretly emails the arrangement to Hermes.

Even the Rich Purnell Maneuver, which many considered to be a clever piece of Hollywood magic, has roots in real life science. An Examination of "The Martian" Trajectory This analysis was performed to support a request to examine the trajectory of the Hermes vehicle in the novel "The Martian" by Andy Weir. One risk to this is hyperbolic trajectories, flight paths that do not loop back to form closed orbits. Teddy Sanders had decided that it was better to take a big risk on Watney than a small risk on the entire crew. “Well,” Venkat began, “If they did this 'Rich Purnell Maneuver,' they'd start accelerating right away, to preserve their velocity and gain even more. on what sol would the Rich Purnell maneuver allow Mark to get the food? That's true for the book at least, the movie messed with the timeline a bit so it isn't as realistic. "Mein Gott" What was the place called that the Hermes crew could enjoy personal time in?

No Rich Purnell Maneuver.” Mitch slammed his fist on the table. Thus, it can be said that the Rich Purnell maneuver, as an Aldrin cycler would be capable of saving Mark Watney in the time frame provided by the book. "The mission designers are heroes and save the day!" It all in your head fam. July 6, 2036 (Sol 229.7) The Hermes flies by Earth, using our planet’s gravitational field to adjust its trajectory.

The Rich Purnell Maneuver was a trajectory course for the Hermes proposed and calculated by astrodynamicist Rich Purnell. That said, Purnell's celestial ballet is brutal on ship and crew alike. The trajectory was actually simulated before writing the book, and while the book never specifies exact dates it's possible to determine them by figuring out the launch windows needed to pull off that trajectory. This isn't a project handed down to him by his bosses: it's a … Instead they made the "Rich Purnell Maneuver" which commits them to making a sling shot maneuver around earth, never actually entering orbit, and heading back in the direction of Mars. They wouldn’t intercept Earth at all, but would come close enough to use a gravity assist to adjust course. The maneuver starts at Mars, and begins a return journey to Earth. And that's not all folks—it's a text file detailing the Rich Purnell Maneuver! "However, since 'Rich Purnell' maneuver would result in the Hermes transiting well within the orbit of Venus, exposing both the crew and spacecraft to large levels of radiation and high temperatures, this rescue scenario may not be a possibility depending on physical limits of the crew and spacecraft", Here is the paper: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20150019662.pdf.

In fact, Purnell is one of the main reasons why McGuire and Burke are such big fans of the book. The Rich Purnell Maneuver would have the Hermes skip entering Earth orbit altogether, and instead go around the Earth and fly straight back to Mars. But I might be chasing the moon here because it would be extremely complicated to do so especially given the fact that the book does not provide much detail into the Rich Purnell Manoeuvre - additionally it is science fiction and the most likely answer to the question is 'no'. * Astrophysics “But I've decided to go with Iris 2. 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." Rich Purnell An astrodynamist at NASA, Purnell independently develops the risky Rich Purnell Maneuver, which allows the Hermes ship to change course and rescue Watney in a “fly-by” before returning to Earth with all six members of the Ares 3 crew.

Watney would have to get to the Ares 4 MAV, modify it, and use it to reach Hermes. We use gravity slingshots around planets all the time. Unfortunately they don’t actually reference the trajectory parameters except incidentially, but it does have some interesting discussion.
