They also explained in a research paper published in the journal “Science Advances” that, according to the analysis of data sent by the Chorong rover spacecraft, indications of water were detected in mineral samples dating back only 700 million years, according to Archyde.com reported today, Thursday.
In addition, they added, the mineral-containing soils found in the samples collected by Chorong had a hard crust that may have formed from rising groundwater or melting ice that has since evaporated.
