Next Sunday (15), the Chinese rover Zhurong completed one year of Mars, where he used his research equipment to explore the Earth’s soil, especially around and inside the affected crater is called Utopia Planitia.
And it is in this area that he has made a discovery that changes everything that scientists think about the existence of water on the Red Earth.
An article was published Wednesday (11) in the newsletter Science Advance describes a study conducted by scientists from the Chinese Academy of Sciences, in collaboration with a scientist from the University of Copenhagen, which is the result of a study based on data captured by the rover.
The study points to evidence that there is more water on Mars recently than previously thought.
Previous studies show that the surface of the Martian surface was covered in water until about 3 billion years ago. The time since the dry season on Mars, turning the Earth into an arid, icy desert it is today, is known as the Amazon period.
“The most important and fresh thing is that we find hydrated food at the landing site [do rover] which sits in young Amazonian terrain, and hydrated minerals are introduced to aquatic life, such as the ground, “said author Yang Liu, a scientist at the Chinese Academy of Sciences’ Space. Climate Key Laboratory and Center of Excellence in Comparative Planetology.
Rock observation by Chinese rover Zhurong provides evidence of recent wet operations on Mars
Zhurong had already completed his first mission in 90 days (Martian days), but continued his route south of his landing site, collecting records as he moved. He uses his two spectrometers to observe the rocks, which he photographs with his microimaging camera and “exploses” them with a laser, creating a “smoke stick” that can also be observed.
Scientists have compared the signatures found on the rocks of Mars by rover with rocks on Earth, finding that some contain more water than dry food. They also see the status of duricrusta geological formation that requires a large amount of water to leave the surface or by a large amount of melting ice.
Although there is no conclusion as to how long water has protected the Earth, given this data, scientists are sure that Amazon’s arrival time is much longer than previously believed.
This also supports the idea that Mars has experienced a combination of wet / heat and dry / cold, not long-term and heavy climate change. “Weather ebbs and streams can be the result of electric shocks or interference from other celestial objects,” Yang said.
