Interstellar travel is a growing interest, and a likely aspect of travelling through space is that people may one day treat it as a vacation just as they do travelling to state parks. To convey this thought, these three posters are advertising three geological sites featured on the planet Mars, in the hopes of interesting those who wish to travel there in the future.
The three landmarks depicted are Cydonia, Valles Marineris, and Olympus Mons. Each poster is a composite made through multiple images taken from different angles or locations being stitched together. For example, the rock texture used for the surface of Mars is made from foodstuffs.
