A study by Chinese scientists, based on data collected by a sonar stationed by the country on Mars, has provided new evidence that there was water on the Red Planet.
Rover, named Zhurong, posted information on the properties of sediments and minerals in the southern part of the vast Utopia Planitia plateau in the northern hemisphere of Mars.
According to the findings of the China National Space Science Center, there are “hydrated minerals that could be explored during future manned flights to Mars.”
A study published in Science Advances reveals the existence of liquid water in the Amazon era – during the last geological era on Mars – in a large basin, and adds other evidence to suggest that this substance “lasted much longer than previously thought.”
It is possible that this site stores water in the form of hydrated minerals and surface residue, the study pointed out.
As early as March, China had released other studies showing that the area to which the Zhurong spacecraft landed in May 2021 may have been corroded by wind or water in the past.
Rover is part of the Tianwen-1 mission, which also includes an orbiting spacecraft and a lander.
Tianwen-1 is China’s first expedition to Mars, and its goal is to find more evidence of the existence of water or ice on this planet, as well as to do research on the material composition of the surface or the properties of the climate.
