Parts of Mars Interior as Wet as Earth’s

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

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

“It’s been puzzling why previous estimates for the planet’s 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.”
