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

The Moon Is Awash In Water

Two new studies indocate that there are “cold traps” on the moon full of water. NASA spied on Luna from a high-flying jet named SOFIA (Stratospheric Observatory for Infrared Astronomy) and found the unique signature of water all over the place on sunlit portions of the moon. A secord study finds that frozen water could be hiding in lunar shadows on 15,444 square miles of the moon’s real estate. Astronauts are probably planning lakeside chateaus as you read this.
