Cubic Snowflakes and Icy Mounds: It’s Winter on Mars

if someone told us let’s think about marsSurely we all imagined it as a red, dry and desolate wasteland. But if you could set foot on the planet during winter, you’d find a very different view, with cube-shaped ice and an icy landscape. If you don’t believe me, take a look at this collection of images and decide for yourself.

like NASA explained in its blogMarsi snow and ice during the winterBut they are not as strange as they might seem, especially at the poles of the planet, where temperatures can reach -123 degrees. “Mars is a very dry place, but if you go to the right place, you’ll find water and ice, just like on Earth. But also, C02 ice or dry ice”, said Sylvain Piceux. Scientist at Jet Propulsion Laboratory from nasa, ,This is the type of water ice that astronauts can use in a future when we go there.

Carbon dioxide frost, or dry ice, can be seen inside craters in winter in the southern hemisphere of Mars.

the dry ice you’re referring to pickaxe is a solid form of carbon dioxide Carbon (CO2). Instead of melting, as water ice does, CO2 ice sublimates. And as this material changes from a solid to a gas, it creates strange landscapes as you can see in these images. on inquiry Mars Reconnaissance Orbiter,

Both water and carbon dioxide can also be formed This frost is much more common than frost on Mars snow. in fact, heViking landers had already seen the existence of frozen water on Mars when they studied the planet in the 1970s,

The HiRISE camera captured this image of the crater rim in late winter.  On the south-facing slope of the crater, which receives less sunlight, a layer of frost has formed.

eagerly, and As stated by NASA in its post, The snowflakes of Mars are cuboidal in shape. On Earth, snowflakes have six sides because of how the water molecules stick together. but what do we have on mars Dry ice, and we know that carbon dioxide molecules clump together in the shape of a four when they freeze, so they have to be cubic. “These snowflakes would be smaller than the width of a human hair,” he claimed. pickaxe,
