Chinese scientists said that wet minerals detected by a Chinese robotic rover on Mars, in a huge depression believed to be the site of an ancient ocean, indicate that water has been present on the planet’s surface for longer than previously thought.
In a research paper published in the journal Science Advances, the scientists said: “According to the analysis of data sent by the Chorong rover spacecraft, we detected indications of water in mineral samples dating back only 700 million years ago.”
It is believed that Mars had water three billion years ago when the second geological age ended.
