This discovery revealed that the red planet was wetter than scientists previously estimated, says a study. Such as quoted from AFP, Friday (22/4/2011).
"By taking the data through the Mars Reconnaissance Orbiter, scientists find primordial carbon dioxide trapped in the ice," wrote a study published in the journal Science.
"These results add to the evidence that it used to be the planet Mars has an atmosphere with the levels of carbon dioxide and water are thin," says the study.
"Large masses of ice that reaches the 12,500 cubic km, equal to the contents of Lake Superior, the largest lake in the North American region," said NASA party in a statement.
"Previously we already know that thin levels of carbon dioxide ice on the surface of mars, but this discovery also add information that the amount of ice that was there was 30 times larger than the diguga before," said the Chairman of the study, Roger Phillips of the Southwest Research Institute in Boulder, Colorado.
