The land of the Arabs on Mars..Water was there in ancient times We've been studying Mars for a few decades, and at this point we have a huge backlog of data, we've started studying it at levels that are comparable to the ways we can study Earth. In the course of studies that scientists are conducting to better understand the ancient environments on Mars, and to find out whether there are suitable climatic conditions for life on the Red Planet, scientists from Northern Arizona University and Johns Hopkins University in Maryland discovered that water was It exists for a short period in an area of ​​Mars called the land of the Arabs. This region is located in the northern latitudes of Mars, and is estimated at an area of ​​about 4,500 square kilometers at its maximum extent, according to their study published in the journal Geology. The land of the Arabs on Mars According to the statement issued by Northern Arizona University, there is a region on Mars that the Italian astronomer Giovanni Schiaparelli named in 1879 AD the name "Arabia Terra", which is a Latin phrase meaning "the land of the Arabs or the Arab land." This area is characterized by whiteness, meaning the presence of white spots in it ranging from light to dark and similar to the natural features of the Arabian Peninsula, as it contains craters and volcanic lakes, some of which are known as pedestal craters, which form a steep cliff. The topography of this area also contains valleys and rocky bands that resemble layers of colored desert sedimentary rocks or badlands. According to the information received from previous studies, this terrain protects the raw materials beneath it from erosion. The hills and piles formed on the surface of the area consist of accumulated layers, and it is believed that the reason for the formation of these layers is volcanic outbursts, winds or groundwater deposits. The rocks of the Arab land on Mars The layers of rocks in the Arabian Land region on Mars and how they formed were the focus of the study titled "A Fragile Record of Transiting Water on Mars" by NASA's Mars Data Analysis Program. "We were specifically interested in using rocks on Mars to better understand past environments 3 to 4 billion years ago, and whether there were suitable climatic conditions for life on Mars," said study co-author Ari Koppel from Northern Arizona University. The university statement says that in order to gain a better understanding of what happened to the formation of rock layers, scientists focused on thermal inertia, which determines the ability of a material to change temperature, as sand with small and loose particles quickly gains and loses heat, while solid rock remains warm for a long time after the darkness.

The land of the Arabs on Mars,Water was there in ancient times

We've been studying Mars for a few decades, and at this point we have a huge backlog of data, we've started studying it at levels that are comparable to the ways we can study Earth.

This region is located in the northern latitudes of Mars, and is estimated at an area of ​​about 4,500 square kilometers at its maximum extent, according to their study published in the journal Geology.
