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 ...
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.
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.

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.
[2] [4] Although Mars' atmosphere consists primarily of carbon dioxide, the greenhouse effect in the Martian atmosphere is much weaker than Earth's: 5 °C (9.0 °F) on Mars, versus 33 °C (59 °F) on Earth due to the much lower density of carbon dioxide, leading to less greenhouse warming.

[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.

Cult sketch group Whitest Kids U’ Know has had countless collaborations, most notably a five-season run of their eponymous IFC series. Their most recently announced project is an animated film ...
