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.
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.
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 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 ...

By Eric Sandler On August 20, 1975 -- 39 years ago today -- NASA launched the first of two spacecraft as a part of their new Viking program and the images they captured back in the '70s and '80s ...
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 ...
The atmosphere of Mars is the layer of gases surrounding Mars. It is primarily composed of carbon dioxide (95%), molecular nitrogen (2.85%), and argon (2%). [ 3 ] It also contains trace levels of water vapor , oxygen , carbon monoxide , hydrogen , and noble gases .
