North Pole ice in jeopardy, scientists say

(CNN) -- The North Pole may be briefly ice-free by September as global warming melts away Arctic sea ice, according to scientists from the National Snow and Ice Data Center in Boulder, Colorado.

Ice Sheet Breaks Loose in Canada

A chunk of ice is shown drifting after it separated from the Ward Hunt Ice Shelf off the north coast of Ellesmere Island in Canada's far north on Sunday July 27, 2008. The sheet is the biggest piece shed by one of Canada's six ice shelves since the Ayles shelf broke loose in 2005 from the coast of Ellesmere, about 500 miles from the North Pole.

Scientists Say Mars Lander Photos Show Ice

Scientists say new photographs from NASA's Mars lander show the robotic probe has dug up pieces of ice on the planet's surface. In Miami, VOA's Brian Wagner reports, the finding is a strong boost to the mission, which hopes to uncover signs of life on Mars.

NASA probe confirms ice on Mars

NASA scientists say photos sent from Mars by the Phoenix Lander confirm ice on the red planet. The presence of water is crucial for research because it helps answer questions on whether life forms, perhaps microbes, exist or existed on Mars. Phoenix dug a trench near Mars' north pole and a sequence of photos shows eight white chucks slowly vanishing. Over the next few weeks Phoenix will analyse the Martian soil and look for organic material. In 2002 another unmanned craft, the Mars Odyssey Orbiter first detected what's thought to be a vast sheet of ice under the barren polar surface.

Mars Lander Stymied by Ice; Like "Scraping a Sidewalk"

The Mars Phoenix lander is having a difficult time digging through the tough ice at the planet's north pole to collect a usable ice sample for analysis, mission scientists say.

Evaporation proves ice on Mars, scientists say

A month after the remarkable spacecraft named Phoenix landed on Mars, elated earthbound scientists reported Friday that their robot digging tool has uncovered chunks of real ice there - the first hard evidence that water exists on the Red Planet.

Water Ice On Mars

cathector sends along a story from SpaceWeather.com on the discovery of water ice on Mars. "Scientists have figured out the mysterious white substance unearthed by NASA's Phoenix lander on Mars. It's frozen water. The breakthrough came last week when Phoenix's stereo camera caught the substance in the act of disappearing. Bathed in martian sunlight for four days, the white substance sublimated — i.e., it transformed from solid to gas without passing through the liquid state. This is how water behaves on Mars.... Some readers have asked, how do we know the white substance is not frozen CO2 (dry ice) instead of frozen water? Answer: Phoenix's landing site is too warm for dry ice. The average daily temperature is about -70 F while dry ice requires temperatures lower than about -109 F.

Scientists Discover Cows Point North

Dr Sabine Begall and colleagues from the University of Duisburg-Essen have discovered that cows tend to point north. The researchers studied deer in the Czech Republic and looked at thousands of images of cattle on Google Earth. The animals tended to face north when eating or resting. "We conclude that the magnetic field is the only common and most likely factor responsible for the observed alignment," the scientists wrote in an article. I guess cows will become the must-have item for long-distance hikers now. Having an edible compass would come in handy if you get lost.

Is the white stuff ice or salt? Mars lander scientists take wait-and-see approach
