The interior of Mars holds vast reservoirs of water, with some spots apparently as wet as Earthís innards, scientists say.

The finding upends previous studies, which had estimated that the Red Planetís internal water stores were scanty at best ó something of a surprise, given that liquid water apparently flowed on the Martian surface long ago.

"Itís been puzzling why previous estimates for the planetís interior have been so dry," co-author Erik Hauri, of the Carnegie Institution of Washington, said in a statement. "This new research makes sense and suggests that volcanoes may have been the primary vehicle for getting water to the surface."

The scientists examined two Martian meteorites that formed in the planetís mantle, the layer under the crust. These rocks landed on Earth about 2.5 million years ago, after being blasted off the Red Planet by a violent impact.

Using a technique called secondary ion mass spectrometry, the team determined that the mantle from which the meteorites derived contained between 70 and 300 parts per million (ppm) of water. Earthís mantle, for comparison, holds roughly 50-300 ppm water, researchers said.
