Scientists add that the beaches on Mars appear to have shifted position over time as data reveals several features dipping towards the north which Cardenas says is an indication t

Scientists have used orbiters and rovers to find dried streams, lakes, and gullies on Mars that hint at its watery past, but their cavalry of robots has struggled to prove the Red Planet ever had an actual ocean.

Mars – dusty, dry, and desert-clad – was once so rich in water it had not just lakes, but oceans, according to a new study. Observations using ground-penetrating radar have revealed underground features consistent with beaches on the red planet,

Mars may have once had a vast, ice-free ocean, according to new evidence from China’s Zhurong rover. Using ground-penetrating radar, the rover revealed sloping, sand-like deposits underground that strongly resemble beach formations on Earth.

China’s Zhurong rover used ground-penetrating radar to find signs of beaches beneath Mars’ surface, adding evidence to the idea the planet hosted an ancient ocean.

Scientists have discovered that Mars once had beaches. While the past presence of water on the Red Planet is no longer in doubt, experts have now found layers of rock beneath Mars' surface, suggesting the likely existence of an ancient ocean.
