Chinese rover Zhurong uncovers evidence of ancient ocean on Mars, raising hopes for past life

China’s Zhurong rover has discovered evidence suggesting Mars once had an ocean. The rover found geological formations similar to coastlines on Earth. These formations indicate the presence of a large body of water in Mars’s past. Scientists believe this ocean existed around 3.68 billion years ago and froze over relatively quickly. This discovery provides further support for the theory that Mars may have once been habitable.
