Climate of Mars. 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 the Earth with help from a telescope. Although Mars is smaller than the Earth ...
Assuming that seasons run from equinox to solstice or vice versa, the season L s 0 to L s 90 (northern-hemisphere spring / southern-hemisphere autumn) is the longest season lasting 194 Martian sols, and L s 180 to L s 270 (northern hemisphere autumn / southern-hemisphere spring) is the shortest season, lasting only 142 Martian sols.

Darian calendar. The Darian calendar is a proposed system of timekeeping designed to serve the needs of any possible future human settlers on the planet Mars. It was created by aerospace engineer, political scientist, and space jurist Thomas Gangale in 1985 and named by him after his son Darius.
Martian polar ice 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 ...
My Favorite Martian is an American sitcom that aired on CBS from September 29, 1963, to May 1, 1966, for 107 episodes. The show stars Ray Walston as "Uncle Martin" (the Martian) and Bill Bixby as Tim O'Hara. [1] The first two seasons, totaling 75 episodes, were in black and white, and the 32 episodes of the third and final season were filmed in ...
Seasons. Mars has an axial tilt of 25.19°, quite close to the value of 23.44° for Earth, and thus Mars has seasons of spring, summer, autumn, winter as Earth does. As on Earth, the southern and northern hemispheres have summer and winter at opposing times. However, the orbit of Mars has significantly greater eccentricity than that of Earth.
Mars sol. Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. A sol is the apparent interval between two successive returns of the Sun to the same meridian (sundial time) as seen by an observer on Mars. It is one of several units for timekeeping on Mars. A sol is slightly longer than an Earth day.
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. [3][5][2] The atmosphere of Mars is much thinner and colder than Earth's having a max ...
