Did Mars once have oceans like Earth?
China’s Zhurong rover may have just found the most compelling evidence yet — a buried Martian beach. Beneath the red sands of Utopia Planitia, ground-penetrating radar revealed layered sediments that look exactly like an ancient shoreline.
From its daring landing in 2021 to its final silent days, Zhurong reshaped how we see the Red Planet. Its discovery of a long-lost coastline suggests Mars was once home to a massive ocean-stable, life-friendly, and perhaps teeming with chemistry that could have sparked biology.
This video explores China’s Tianwen-1 mission and Zhurong’s journey across Mars, the discovery of subsurface beach deposits as direct evidence of an ancient ocean, what this means for the search for life, and how it fuels the new space race between China and the United States. We also look ahead to the Tianwen-3 sample return mission and what it could reveal about Mars’s past.
Could life have started on the shores of ancient Mars, just as it may have on Earth? And who will be the first to uncover it — China or the United States?
