Rovers Reveal Ancient Ocean Evidence on Mars

A Chinese rover, Zhurong, has discovered features on Mars that suggest the presence of an ancient ocean, including pitted cones and polygonal troughs, in the Utopia region. These findings, published in Scientific Reports, support the theory that a vast ocean covered a third of Mars around 3.7 billion years ago. However, some scientists remain skeptical, citing potential erosion by Martian winds. The study highlights the need for further exploration to confirm the existence of a Martian ocean, which could have implications for understanding the potential for life on Mars.
