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 JWST has captured its first Mars pictures, and they could reveal more about the planet's atmosphere. James Webb Space Telescope's first pictures of Mars could reveal more about the atmosphere ...
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 ...
In summer 1965, the first close-up images from Mars showed a cratered desert with no signs of water. [1] [2] [3] However, over the decades, as more parts of the planet were imaged with better cameras on more sophisticated satellites, Mars showed evidence of past river valleys, lakes and present ice in glaciers and in the ground.

The year 2024 had major space events including a total solar eclipse and historic moon landing. There were moments, though, that reminded us how challenging space exploration can be.
Reprojected view of warm-season flows in Newton Crater. Seasonal flows on warm Martian slopes (also called recurring slope lineae, recurrent slope lineae and RSL) [1] [2] are thought to be salty water flows occurring during the warmest months on Mars, or alternatively, dry grains that "flow" downslope of at least 27 degrees.
