Scientists estimate that Mars has experienced six to twenty ice ages in the last 300-800 million years.
A team of researchers from Colgate University in New York state has found traces of dozens of ice ages on Mars.
The researchers analyzed photographs of 45 Mars glaciers that were taken by NASA’s Mars Reconnaissance Orbiter (MRO).
Scientists have studied the distribution of about 60 thousand rocks and found that their accumulations were formed as a result of changing cycles of advancing and retreating ice.
According to the researchers, the grouping of large rocks suggests that Mars has experienced six to twenty ice ages in the last 300-800 million years.
“There are really good models for Mars’ orbital parameters for the last 20 million years,” said Joe Levy, a planetary geologist and assistant professor of geology, while revealing analysis of the mysterious glaciers and rocks of Mars.
He also added that “there’s a lot of work to be done figuring out the details of Martian climate history including when and where it was warm enough and wet enough for there to be brines and liquid water.”
