This story is part of Welcome to Mars, our series exploring the Red Planet.
It turns out that Mars might have a fashion sense, and it’s become a classic pattern: polka dots. NASA’s Mars Reconnaissance Orbiter, a longtime resident of the planet, just captured a remarkable image of the dunes with noticeably rounded shapes.
MRO’s High Resolution Imaging Experiment (HiRise) camera captured some images Wonderful dunes before, including some of the most popular models Crescent dunes. “Dunes of many shapes and sizes are common on Mars. In this example, the dunes are almost perfectly circular, which is unusual,” Planetary geologist Alfred McEwen wrote Feature image for HiRise today Thursday.
Take a closer look at these delightfully circular Martian dunes.

Mars is a place full of dust, sand, and wind, making it an ideal planet for forming sand dunes. A closer look shows that these dunes are not exactly circles. “It’s still somewhat uneven, with steep slopes at the southern ends. This suggests that the sands generally move to the south, but the winds may be variable,” said McEwen.
HiRise Camera is powered by the University of Arizona. MRO picked up Dunes in late November last year. The researchers were studying the area to monitor seasonal changes in frost coverage. This photo shows that frost is absent from the landscape.
Views of Mars like these may seem otherworldly, but they show a connection between our two planets. we’ve got Sand dunes are here on EarthThey also tell similar stories about the wind and the changing of the seasons. There is so much beauty to be found on both planets.
