"This is a very interesting result," says Eva Scheller, a planetary scientist at the California Institute of Technology who wasn't involved in the new research."We have very few recorded evidences of 'young' liquid water systems on Mars. And for the ones we have, they were usually in the form of salt minerals."
But Zhurong's instruments spotted water molecules locked away in the rock,"which is very interesting and different from other young liquid water environments that have been observed," Scheller said."It means that particular forms of water-bearing minerals would have formed at much later time periods than have previously been considered in other scientific studies.", dating back to the Noachian age more than 3.7 billion years ago.
