A team of scientists from the Chinese Academy of Sciences together with scientists from the University of Copenhagen, using a Chinese rover, has found evidence that water may exist on the surface of Mars. Longer than previously thought.

Previous studies indicated that liquid water was present on the surface of Mars until about 3 billion years ago. The time when the waters of Mars dried up is known as Amazon period.

New evidence points to this Water can stay much longer than previously thought.

Rover Zurong The surface of Mars was analyzed for a year. Located in the largest shock pool on the planet – Utopia Planetia. Spectrometers are used to analyze rocks. It also takes pictures of the rocks with a micro-camera.

Scientists have compared the signatures found in Martian material to terrestrial rocks. Some samples were found to be wet metal. The researchers also found crust layersthat is, layers consisting of silica (SiO2), alumina and iron oxide.

Wet Minerals and Duricrust Indicates the presence of salt water in the liquid state Below the surface of Martian soil, which may have emerged from the melting of Earth’s ice. This may have happened during the timer climatic disturbancesfor example due to volcanoes or meteor impacts.

Further studies on the mineralogy and spatial extent of these specific rocks will allow climatic conditionsWhat prevailed when the water was liquid on the surface.

The cold, dry age of the Amazon may have been halted by the episodic and short-lived global warming phenomenon It causes the ground ice to melt.

In-situ selection (in-site – editor) refers to these environments The Amazonian surface hydrosphere is more active than Mars than previously thought. The Zhurong landing site may have a significant amount of water available in the form of hydrated metals and possibly ice,” the authors wrote in their article.

People can use potential resources in the future Mars exploration.
