Huge Sheets of Ice Found Hidden Just Beneath the Surface of Mars

"There is shallow ground ice under roughly a third of the Martian surface, which records the recent history of Mars. What we've seen here are cross-sections through the ice that give us a 3-D view with more detail than ever before."

"The discovery reported today gives us surprising windows where we can see right into these thick underground sheets of ice. It's like having one of those ant farms where you can see through the glass on the side to learn about what's usually hidden beneath the ground."

"If you had a mission at one of these sites, sampling the layers going down the scarp, you could get a detailed climate history of Mars. It's part of the whole story of what happens to water on Mars over time: Where does it go? When does ice accumulate? When does it recede?"
