When Mars appeared to pass close by two faint stars with no effect on their brightness, Herschel correctly concluded that this meant that there was little atmosphere around Mars to interfere with their light. [3] Honore Flaugergues's 1809 discovery of "yellow clouds" on the surface of Mars is the first known observation of Martian dust storms. [4]
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.

Observers on Mars can view transits of Phobos and transits of Deimos across the Sun. The transits of Phobos could also be called partial eclipses of the Sun by Phobos, since the angular diameter of Phobos is up to half the angular diameter of the Sun. However, in the case of Deimos the term "transit" is appropriate, since it appears as a small ...
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 ...
1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
The land was always covered in clouds and mist. [2] A high altitude visual phenomena, probably a condensation cloud, [3] was seen above this region in late March 2012. [4] NASA tried to observe it with some of its Mars orbiters, including the THEMIS instrument on the 2001 Mars Odyssey spacecraft and MARCI on the Mars Reconnaissance Orbiter. [3] [4]
LOS ANGELES (Reuters) -NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater ...
