Mars may not seem like a prime holiday spot with its arid landscape and punishing radiation levels, but it once boasted beaches, researchers have found.

While previous discoveries of features including valley networks and sedimentary rocks has suggested the red planet once had flowing rivers, there has been debate among scientists over whether it also had oceans.

Now researchers say they have fresh evidence to support the idea after discovering buried beaches on Mars.

Writing in the Proceedings of the National Academy of Sciences, the scientists report how they made the discovery after they analysed below-ground imaging data from China’s Zhurong rover.

“Zhurong was sent to southern Utopia Planitia near locations where paleoshorelines have been mapped from satellite data,” said Dr Benjamin Cardenas, a co-author of the research from Penn State University.

The authors say the results from the northern lowlands of Mars are similar to those obtained at shorelines on Earth using ground-penetrating radar: both indicate features in the subsurface material that are tilted – and with a similar angle – towards the lowland, or ocean, direction.
