NASA discovered unusual sand dunes on Mars

NASA’s Mars Reconnaissance Orbiter (MRO) spacecraft, a longtime resident of the planet that has been launched since 2005, has captured a fascinating image of sand dunes with their unusually round and remarkable shape. Notice on the Red Planet’s surface.

In the past, the MRO’s high-resolution camera (HiRise) has captured images of some interesting dunes, including some crescent-shaped dunes. The data sent back also shows that the sand dunes here come in a variety of shapes and sizes. But the latest image shows some of the dunes are almost perfectly circular, and according to scientists this is “unusual”.

Mars is a dusty, sandy and windy planet. And that makes it a perfect place to form sand dunes. However, if we look closely we will see that these dunes are not perfect and exact circles.

“They’re still a bit asymmetrical, with sloping slides at the southern end. This suggests that the sand usually moves south, but the winds can change,” said planetary geologist Alfred McEwen.

The MRO’s HiRise camera system is currently controlled and operated from Earth, affiliated with the University of Arizona in the US. The MRO photographed these dunes at the end of November last year. Scientists are focusing on this area to track the seasonal changes of the dunes. This resulting image shows the typical frost-free area of ​​winter on Mars.

Views of Mars like these can make it look like another world, but they also show a connection to our planet. We also have beautiful sand dunes on Earth, and they tell similar stories about the wind and the changing of the seasons.
