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.
[124] [125] Large changes in the tilt explains many ice-rich features on Mars. Studies have shown that when the tilt of Mars reaches 45 degrees from its current 25 degrees, ice is no longer stable at the poles. [126] Furthermore, at this high tilt, stores of solid carbon dioxide (dry ice) sublimate, thereby increasing the atmospheric pressure.
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. Therefore ...
The start and end dates of a season on any planet of the Solar System depends on same factors valid on Earth, but which have different values ... Mars: 317.68 +52.89 ...
Mars has seasons that are similar to Earth's, because its rotational axis has a tilt close to our own Earth's (25.19° for Mars, 23.44° for Earth). During each year on Mars as much as a third of Mars' thin carbon dioxide (CO 2) atmosphere "freezes out" during the winter in the northern and southern hemispheres. Scientists have even measured ...
Mars’s moons don’t get much credit. But they’re small, lifeless, and weird little things. Here’s everything you should know about them.

The Clancy Mars year is reckoned from one Martian northward equinox to the next (L s = 0°), and specific dates within a given year are expressed in L s. The Clancy Mars year count is approximately equal to the Darian year count minus 183. The Allison Mars sol date epoch equates to L s = 276.6° in a year that is undefined in the Clancy Mars ...
