Found a Lot of Ice in Mars' South Pole

NASA found that the south polar region of Mars has ice that are 30 times more than previous estimates. These findings suggest that the red planet was wetter than scientists previously estimated. By taking the data through the Mars Reconnaissance Orbiter, scientists found an ancient carbon dioxide trapped in ice. These results add to evidence that Mars has an atmosphere with carbon dioxide and water are slim.

"Great ice mass has reached 12,500 cubic km, equal to the contents of Lake Superior, the largest lake in North America," said NASA. "Previously we already know that the thin levels of carbon dioxide in the ice surface of mars, but this discovery also adds information that the amount of ice that was there was 30 times larger than previously thought," said Roger Phillips of Southwest Research Institute in Boulder , Colorado.
