China’s Zhurong rover has uncovered evidence suggesting the existence of an ancient ocean on Mars. Using ground-penetrating radar, scientists detected sandy, beach-like structures beneath the Martian surface, supporting the hypothesis that a large ocean, known as Deuteronilus, existed around 3.5 to 4 billion years ago. During this period, Mars had a thicker atmosphere and a warmer climate, potentially creating conditions suitable for life.

The Zhurong rover, which operated between May 2021 and May 2022, traveled 1.9 km across Utopia Planitia, a vast plain in Mars’ northern hemisphere. It used radar to probe up to 80 meters below the surface, revealing layers of material resembling sand at depths of 10 to 35 meters. These layers had slopes similar to terrestrial beaches, indicating ancient coastal deposits shaped by waves and tides.

The discovery strengthens the hypothesis that Mars once had a long-lasting body of water. Researchers ruled out alternative explanations, such as wind-blown dunes or ancient river deposits, as they did not match the observed patterns. The structures were preserved under layers of dust and volcanic material, further confirming their coastal origins.

Mars, like other planets in the solar system, formed around 4.5 billion years ago. Scientists believe this ocean existed for nearly a billion years before Mars underwent drastic climate changes that led to the loss of surface water. Some of this water may still be trapped underground, offering insights into the planet’s geological history.

The identification of these coastal deposits opens new possibilities for future exploration. Missions targeting these regions could search for signs of past life, as shorelines are considered prime locations for astrobiological research. Similar environments on Earth played a crucial role in the emergence of life, making the study of Martian shorelines vital for understanding the potential for life beyond Earth.
