NASA’s HiRISE Camera Recently Imaged a Martian Dust Devil. But Why Study Them? - by et_exists

While Earth and Mars share similar dust devil characteristics, one drastic difference between the two planets is their, also known as the axial tilt, which is the angle between a planet’s rotational axis and its orbital axis. Planetary objects are almost never perfectly upright, and frequently rotate at an angle, which can change over long geologic time periods, anywhere from thousands to millions of years, and could have an affect on Martian dust devil activity.varies between 22.
“That is a good question that gets to our understanding of how long-term changes in dust loading affect the climate,” Dr. Matthew Chojnacki, a research scientist at the Planetary Science Institute who works with HiRISE, tells. “From what I can tell from the literature, dust devils are predicted to be more active during high obliquity than they are today with a tilt closer to 25°, but that may be offset by the lesser amount of dust lofted in those conditions.

Dust devils are just one of a myriad of unique features on the Red Planet, and understanding their processes and patterns will continue to teach scientists more about our nearest planetary neighbor, for its present, past, and even its future. What new discoveries will scientists make about dust devils on Mars in the coming years and decades? Only time will tell, and this is why we science!
