(Caracas, Aug. 08, 2012) – Mars images from a NASA spacecraft over a ten-year interval reveal the dramatic transformation an avalanche of ice caused in a region of the red planet according to the website of the US aerospace agency.
In December 2006, the Mars Reconnaissance Orbiter ship photographed the stratified deposits of the North Pole of Mars, whose steep cliffs are "one of the most actively changing areas on the planet," according to NASA. A second photo of the same site obtained on March 25th shows that the landscape has almost completely changed, as it shows blocks of ice that cover the ground and do not appear in the first.
NASA explained that the ice and snow covering the Martian surface are not the same as those on Earth because it is actually carbon dioxide, known as the name of dry ice. 19659004] The HiRISE instrument photographed the same areas documented in 2006-2007 so that scientists could detect changes. "This large base allows us to see significant and rare changes, as well as many small changes," the scientists wrote.
