It’s a shame Elon Musk hasn’t colonised Mars yet, as something mysterious is happening there right now that has experts perplexed.
Sand dunes on the surface of Mars are “nearly perfectly round,” according to new photographs provided by NASA.
The photographs were collected in Mars’ northern hemisphere by the High Resolution Imaging Science Experiment (HiRISE) camera system on NASA’s Mars Reconnaissance Orbiter.
According to a statement from the University of Arizona, the reason they are so rare is that “sand dunes of different forms and sizes are prevalent on Mars. It’s remarkable, but in this case the sand dunes are almost exactly spherical.
Yet, it is currently unknown what caused these sand dunes to resemble almost perfect circles.
The statement says, “They are still slightly uneven, with steep slip slopes on the south ends. “This suggests that while winds may vary, sand generally flows in a southerly direction.
“This observation looks to be clear of frost; it is one of a series of pictures to track how frost disappears in the late winter. An earlier photograph depicts the area while it was coated in frost.
