Pay attention, future astronauts.
In stark contrast to the rest of the planet's rusty-red surface, Mars' south pole is covered in bizarre, Swiss cheese-like formations.
"Mars experiences 100,000-year cycles in which its poles vary from tilting more toward or away from the Sun," Buhler said in a"These variations cause the amount of sunlight shining on each latitude band, and thus the temperature of each band, to cycle, too." In the study, Buhler utilized a numerical model "to simulate the build-up of the layers over time." He then ran that model "approximately one billion times," until he was finally able to statistically determine which specific configuration of water deposition best matched the Swiss cheese layers present on the planet today.
