Fig 1.- A Journey to Mars.

Flying Lession

Witney is marooned on Mars and forced on a lengthy journey with the hope of rescue. While the astronaut's path is fictitious, it takes place on real areas of Mars. Witney's trek takes him through an area called the Acidalia Planitia and the large crater Schiaparelli. The name Acidalia Planitia is a Martian landmark, and a nod to a real-life location. We've named some of the domes ancient land on the Red Planet. Mars Trek's bookmark for "The Martian" allows you to follow Witney's intended path from Acidalia Planitia to the large crater Schiaparelli. Waypoints along the route provide you with expert commentary from Jim Green, Director of the Planetary Science Division at NASA Headquarters in Washington.
