Ice Covers South Pole of Mars

• Satellite finds huge ice deposits on Mars' south pole
• Ice 2.3 miles thick in some areas
• Appears to be frozen water covered by layer of frozen CO2
• If melted, ice would cover planet with 36 feet of water

WASHINGTON (Reuters) -- A spacecraft orbiting Mars has scanned huge deposits of water ice at its south pole so plentiful they would blanket the planet in 36 feet of water if they were liquid, scientists said Thursday.
The scientists used a joint NASA-Italian Space Agency radar instrument on the European Space Agency Mars Express spacecraft to gauge the thickness and volume of ice deposits at the Martian south pole covering an area larger than Texas.
The deposits, up to 2.3 miles thick, are under a polar cap of white frozen carbon dioxide and water, and appear to be composed of at least 90 percent frozen water, with dust mixed in, according to findings published in the journal Science.Scientists have known that water exists in frozen form at the Martian poles, but this research produced the most accurate measurements of just how much there is.
