Scientists have found a new way to reconstruct the history of the climate on Mars

Scientists have repeatedly tried to understand how Mars went from a state potentially more like today’s Earth to the desolate place it is today. Conducted by geologists from Monash University (Australia), the study provided fresh data on the periods in the history of Mars markedly increased erosion.

Scientists’ findings published on the University website. They point to a time period when the climate on Mars was more erosive. This allows us to judge that in the history of the planet there were long periods of time when water in a liquid state moved over the surface of Mars.

“If we want to know if there was life on Mars, we need to understand the sedimentary record,” said study lead author Dr. Andrew Gunn. He added that the new study helps to determine “the timing and rate of erosion and accumulation of sediments throughout the geologic history of Mars in a completely new way.”

In their study, the experts were able to show how the huge amount of sand in the craters of Mars can provide information about the history of the planet’s climate. This, in turn, will help to understand when conditions suitable for life could have existed on Mars.

The researchers used a variety of information to estimate the size of the crater sand deposits and what formed them, including geological maps, climate modeling and satellite data. They synthesized and interpreted the information they received to understand the control mechanisms and timing of erosion on Mars.

Considering the increase in the level of erosion in different periods of the history of Mars, we can conclude that there used to be rivers that erode the soil, experts concluded.

Earlier astronomers discovered water hidden under the surface of Mars. According to scientists, the discovery was made in the heart of the Mariner Valley canyon, located near the equator.
