Chinese scientists say wet minerals discovered by a Chinese robotic rover in a massive depression thought to be the site of an ancient ocean indicate that water has been on the planet’s surface for longer than previously thought. .
According to a research paper published Wednesday in the journal Science Advances, scientists say they have identified signs of water in mineral specimens dating back only 700 million years, based on analysis of data sent by the Chorong spacecraft. Has been.
Mars is believed to have had water 3 billion years ago, when its second geological period, called the Hesperian Age, ended, and there is no water on the surface of Mars in the present-day Amazon era.
The Chinese scientists added that the soil containing the minerals found in the collected samples of churang has a hard crust that may have been formed by rising groundwater or melting ice that has since evaporated.
The Chorong spacecraft has been moving about two kilometers from its landing site and has been collecting data since it arrived on Mars in May last year.
