Found: Hidden Water on Mars

“Vast amounts of ancient Martian water may have been buried beneath its surface instead of escaping into space, scientists report in the journal Science. The findings, published Tuesday, may help untangle a clash of theories seeking to explain the disappearance of Mars’ water, a resource that was abundant on the planet’s surface billions of years ago.

Through modeling and data from Mars probes, rovers, and meteorites, researchers at the California Institute of Technology found that a broad range — between 30 to 99 percent — of the Red Planet’s earliest amounts of water could have vanished from the surface through a geological process called crustal hydration, where water was locked away in the rocks of Mars.”

— “Mars might be hiding most of its old water underground, scientists say,” Joey Roulette, The Verge

Martian Water

Martian Water

There’s a 12-mile-wide lake of liquid water a mile beneath the southern ice cap of Mars. The discovery was made using the Marsis radar instrument on board the European Space Agency’s Mars Express, which has been orbiting the red planet for 15 years. Thirsty astronauts shouldn’t expect instant refreshment, though. The lake is filled with salt water.
