The climate on Mars may have changed significantly in the relatively recent past. The red planet has survived
Interestingly, deposits of this kind are more oftenare directed to the high latitudes of Mars, and to its equator. This suggests that in the circumpolar regions of the planet, glaciers advanced and retreated much more often. Presumably this was due to how the tilt of the planet's rotation axis changed in past eras.
Research text
Ice ages occurred after Mars had lost much of its atmosphere. Unusual deposits pointed them out to scientists.
In order to examine the deposits, the authorsThe work studied the landforms of Mars, and then analyzed photographs of lobate sediment margins over recent decades. As a result, many of them were formed as a result of several cycles of glacial advance and retreat that occurred in the last 800 million years.
The authors suggest that there may be ancient Martian ice in the interior of the cobblestone clusters, the study of which can tell us about where the water reserves disappeared from the planet.
