A new astrophysicist study proves the movement of water and carbon dioxide on Mars

Thanks to the south polar layered deposits of H20 and CO2 ice, scientists have elucidated the climatic history on Mars. These studies are published in Geophysical Research Letters. This is reported by the news portal PLANET TODAY.

Astrophysicists suggest that the long-term global movement of Martian water from the mid-latitudes to the poles, with a function of the planet’s orbital configuration, is due to a decrease in H2O ice deposits due to a tilt or tilt factor of the rotational axis.

“None of the analyzed deposits provide data on the global water cycle that can be linked to a specific orbital history. Here, I fill this gap by analyzing the formation of an H2O ice layer in the massive 510,000-year-old CO2 icy deposits at the south pole of Mars. Previously, only average sedimentation rates over millions of years have been obtained, which is about ten times greater than the orbital cycles of Mars,” said Peter B. Buhler, researcher at the Institute of Planetary Sciences and lead author of the study.

It turned out that the history of stratification is direct evidence of how water and carbon dioxide moved around the planet.

Until recently, the quantitative rate at which water moves in the 100,000-year cycles of Mars was only partially known. Now, scientists have uncovered accurate data thanks to the study of the thickness of the water layer, water vapor, temperature, carbon dioxide and the atmosphere of the planet.

“The history of atmospheric pressure on Mars and the presence of water are important information for understanding the basic workings of the Martian climate and near-surface geological, chemical, and possibly even biological history. In particular, the results of this work represent an important step forward in deciphering the underlying mechanisms of the Martian water cycle, and thus the long-term availability of near-surface water ice or even liquid brines. we know her.”

Earlier it became known about the signals from space, which were mistaken for messages from aliens.
