The Chinese Journey found signs of global flooding during ancient Mars

Chinese scientists published an article in the magazine that revealed the significant discovery made by Jjujun in the vicinity of his landing on the Utopia plain. According to a georadar maroon on board, two severe floods could have occurred in the area under study more than 3 and 1.5 billion years ago. Georadar cannot tell exactly whether it was water or lava streams, but indirect data lead scientists to think about water.

The lower the frequency, the deeper the radio waves reach the surface of the planet, the lower the resolution, and the smaller objects are no longer the same as the radar. The Zhujuna was able to distinguish the structure of the subsurface area of Mars up to 100 m deep, which allows us to study the geologic history of the Red Planet and to answer the question: was it water in liquid form and an opportunity to create biological life?

The radar data collected between 25 May and 6 September 2021 correspond to a section about 1,171 m south of the landing site.

The observed subsurface structure suggests that in two prehistoric periods, the region was flooded on a large scale, as shown by the accumulation of stones. The first "flood" occurred between 3.5 and 3.2 billion years ago, the last one about 1.6 billion years ago, and scientists do not rule out that the flow of lava from the volcanoes of young Mars could have led to such a structure. Nevertheless, a meeting of lava with sedimentary rocks would have created a somewhat different picture than the one found by the Mars, which encourages researchers to believe the existence of water on ancient Mars.

Another indirect evidence that water could have been found on ancient Mars is found by the finds of hydrated minerals found on the surface of the planet by other scientific instruments called Jujuna. Such minerals are formed by the rise of groundwater or by the melting of water ice. It is now in hibernation, surviving the Martian winter in the area of work, but it will soon wake up and continue its scientific work.
