Furthermore, rarer "Mother of Pearl" clouds have formed when all particles of a cloud form at the same time, creating stunning iridescent clouds. [17] The first images of Mars sent by Mariner 4 showed visible clouds in Mars' upper atmosphere. The clouds are very faint and can only be seen reflecting sunlight against the darkness of the night sky.

In 2018, it was announced that a subglacial lake was discovered below the south polar ice cap of Mars. The lake was detected by Mars Express orbiter, and is 20 km (10 mi) long, lying under ca. 1.5 km (1 mi) of glacial cover, with water temperature estimated to be −68 °C (−90 °F), and having an extremely salty brine.

Generating accurate true-color images of Mars's surface is surprisingly complicated. [5] There is much variation in the color of the sky as reproduced in published images; many of those images, however, are using filters to maximize the scientific value and are not trying to show true color.
If you’ve ever indulged in the habit of cloudspotting, you’ve probably seen all kinds of things in the sky, from animals and faces to UFOs and cartoon characters. But did you know that our ...
The clouds are almost 50 miles high, and likely composed of carbon dioxide as opposed to water.In the second GIF, the so Mars rover films magnificent Martian clouds soaring over the red desert ...
Images from the Curiosity rover show clouds nearly 80 kilometres high in Mars’s sky. Due to the low temperatures (below 150 K) at that altitude, the clouds were probably composed of CO 2 or dry ice , as opposed to water ice [ 3 ] [ 8 ] The interesting observation from the Curiosity rover is that carbon dioxide cloud formations were documented ...
Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [8] A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars. [9] Layers can be hardened by the action of groundwater.
