Current research suggests that Mars is in a warm interglacial period which has lasted more than 100,000 years. [134] Because the Mars Global Surveyor was able to observe Mars for 4 Martian years, it was found that Martian weather was similar from year to year. Any differences were directly related to changes in the solar energy that reached Mars.
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 ...
During the winter season on Mars, temperatures at the planet’s polar caps can reach below CO 2 ’s condensation temperature (150 K). Noted as orbit #10075 by Dr. Ivanov and Dr. Muheleman of the Mars Global Surveyor, data from the MOLA instrument recorded cloud returns at the planet’s south polar cap during the southern winter season.

The days are short and the nights are long. That can only mean one thing: The winter solstice is coming. The first day of winter for the northern hemisphere of Earth will begin on Dec. 21 at ...
The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...
[3] [12] [13] No evidence of present-day liquid water has been discovered on the planet's surface because under typical Martian conditions (water vapor pressure <1 Pa [14] and ambient atmospheric pressure ~700 Pa [15]), warming water ice on the Martian surface would sublime at rates of up to 4 meters per year. [16]
As holiday lights brighten streets and the season of cheer unfolds, Dec. 21 marks the winter solstice this year -- a reminder that the darkest day of the year is upon us.
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.
