Enormous Water Reservoirs Discovered on Mars—And Potential for Alien Life, But There’s a Catch

By: Georgia | Published: Aug 13, 2024

Imagine an ocean deep enough to submerge Mount Everest’s peak—that’s what scientists at UC Berkeley and UC San Diego might have found beneath Mars’ surface. 

Published in the Proceedings of the National Academy of Sciences, this discovery points to a hidden aquatic expanse, stirring up possibilities of alien life nestled under the Red Planet’s crust.

Mars Quakes Reveal Hidden Hydration

Through the trembles of Marsquakes and echoes of meteor impacts, researchers have pieced together a picture of what lies beneath Mars’ dusty surface.

The Catch: Water Beyond Reach

Finding water on Mars is one thing; accessing it is another.

Buried 11.5 to 20 kilometers beneath the surface, this Martian water poses a major challenge, as it’s out of reach with our current technology, setting up a tantalizing but tough puzzle for future explorers.

A Potential Cradle for Life

“Deep environments on Earth support life, so why not on Mars?” asks Michael Manga from Berkeley.

This intriguing statement opens the door to the possibility that these hidden Martian waters could be more than just ice—they could be havens for life, awaiting discovery.

Extreme Life on Earth Inspires Martian Hopes

Life thrives in Earth’s most extreme habitats—from the black depths of our oceans to the isolated ecosystems of deep caves.

These discoveries fuel speculation that Mars’ subterranean waters could also support life forms, thriving in conditions once thought inhospitable.

Mars' Watery History

Today’s Martian surface is a desert, but its landscape tells a tale of rivers, lakes, and perhaps oceans that once sculpted its terrain.

Drilling Challenges Echo Earth’s Depths

The depths at which this Martian water lies are comparable to Earth’s deepest borehole, the Kola Superdeep Borehole, which itself is a marvel of human endeavor.
