Spring warming in certain areas leads to CO 2 ice subliming and flowing upwards, creating highly unusual erosion patterns called "spider gullies". [104] Translucent CO 2 ice forms over winter and as the spring sunlight warms the surface, it vaporizes the CO 2 to gas which flows uphill under the translucent CO 2 ice.
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 higher density during spring and fall is reduced by 25% during the winter when carbon dioxide partly freezes at the pole caps. [6] The highest atmospheric density on Mars is equal to the density found 35 km (22 mi) above the Earth's surface and is ≈0.020 kg/m 3. [7]

The only difference between spring temperatures and summer temperatures is due to the relatively high eccentricity of Mars' orbit: in northern spring Mars is farther from the Sun than during northern summer, and therefore by coincidence spring is slightly cooler than summer and autumn is slightly warmer than winter.
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 ...
This supports the theory of the long-term global weather of Mars consisting of cycles of global warming and cooling; during cooling periods, water gathered at the poles to form the ice layers, and then as global warming occurred, the unthawed water ice was covered by dust and dirt from Mars' frequent dust storms.
KW: Musk is saying that in the next 30 years, we’re going to have a million people on Mars. No way that you could scale up to a million people on Mars without something catastrophic happening ...
