China's Mars Rover Uncovers Ancient Ocean Shoreline on Red Planet
China's Zhurong rover has discovered evidence of an ancient ocean shoreline on Mars, suggesting a massive body of water once existed in the planet's northern lowlands. Using onboard cameras and ground-penetrating radar, researchers identified features like pitted cones and sediment channels indicative of a coastline. This finding supports the theory of a Martian ocean during the Hesperian period, around 3.68 billion years ago, and raises questions about the potential for past life on Mars. However, some scientists remain skeptical due to erosion concerns.
