Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738.. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from Earth with help from a telescope.
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 surface appearance of some regions of Mars is due to how this unit has degraded. It is a major cause of the surface appearance of lobate debris aprons. [56] The layering of the upper plains mantling unit and other mantling units are believed to be caused by major changes in the planet's climate.

The most detailed images and observations ever captured of one of Mars' moons have been released by scientists. Pictures taken by Hope Probe from the UAE Space Agency's Emirates Mars Mission (EMM ...
It's generally accepted that mantle is ice-rich dust that fell from the sky as snow and ice-coated dust grains during a different climate [47] One evidence of its ice-rich nature is the presence of gullies which form when some of the ice melts. [48] [49] [50] The images below, all taken with HiRISE, show a variety of views of this smooth mantle.
Mars has lots of water, but future astronauts won't exactly be able to scoop it into bottles -- it's generally trapped in ice deposits below the surface. Scientists from Penn State think climate ...
Mars climate simulation models date as far back as the Viking missions to Mars. Most Mars climate simulation models were written by individual researchers that were never reused or open-sourced. By the 1990s the need for a unified model codebase came into being, due to the general impact of the internet on climate modelling and research.
