Liquid water probably had Mars until about 700 million years ago and not until three billion years ago which is the prevailing theory to this day. This was shown by a Chinese study, which is based on data collected by the Chinese rover Zhurong. Scientists from the National Center for Space Science in Beijing and the Chinese Academy of Sciences, led by Yang Liu, published the paper in the journal Science Advances.
The rover has been moving in the large and relatively unexplored crater Utopia Planitia of northern Mars since May 2021 and to date has covered a distance of about two kilometers, according to the APE-MPE.
The two Zhurong spectrometers analyzed rocks on the crater surface and found the chemical “signature” of water in hydrated minerals, which come from the most recent era in Martian geological history, the so-called “Amazon”. A time when scientists until now thought it was cold and dry. The findings of Chinese scientists should, however, be considered preliminary and confirmed by other findings.
