By IANS | Posted 2 hoursWashington: Using radar data from NASA's Mars Reconnaissance Orbiter (MRO), scientists have found a record of the most recent Martian ice age recorded in the planet's north polar ice cap. Scientists produced images called radargrams that are like vertical slices though the layers of ice and dust that comprise the Martian polar ice deposits. The researchers identified a boundary in the ice that extends across the entire north polar cap. During summertime in the planet's north, the remaining northern polar cap is all water ice; the southern cap is water ice as well, but remains covered by a relatively thin layer of carbon dioxide ice even in southern summertime. Mars has bright polar caps of ice that are easily visible from telescopes on Earth.
