    Huge reserves of water ice discovered on Mars

    Huge ice sheets more than 300 feet deep have been discovered on Mars, making it possible that human astronauts could have access to almost limitless water, scientists said Thursday.


    "Astronauts could essentially just go there with a bucket and a shovel and get all the water they need," said one of the report's authors, Shane Byrne of the Lunar and Planetary Laboratory at the University of Arizona.

    It has been known for some time that some locations on Mars have water ice just below the surface — but until now, there has been no accurate way to know just how much.


    The new data, collected in high-resolution three-dimensional images from two U.S. satellites, reveal at least eight locations where massive shelves of water ice are deposited from just below the Martian surface as far deep as 100 meters, or roughly 330 feet, according to the report, which was published in the journal Science.

    "The discovery reported today gives us surprising windows where we can see right into these thick underground sheets of ice," Byrne said. "It's like having one of those ant farms where you can see through the glass on the side to learn about what's usually hidden beneath the ground."


    The ice shelves contain distinct layers, which could preserve a record of Mars' past climate, the scientists said. Of probably wider public interest, however, is that the ice shelves "might even be a useful source of water for future human exploration of the red planet," they said.



    The ice probably started as snowfall that compacted into massive fractured layers. They're at relatively easy-to-reach locations with less hostile conditions than at Mars' polar ice caps, according to NASA's Jet Propulsion Laboratory — at latitudes roughly equivalent on Earth to Scotland or the tip of South America.

    The discovery could add fuel to NASA's efforts to send humans to Mars, one of the objectives President Donald Trump cited last month when he directed the space agency to focus its efforts on returning to the moon.

    Very interesting! So that is a cross section of the ice... Do you know if the layer above the blue one is ice or soil?

    Yes, would save a lot of weight by not having to drag water up there.

    Here's a good Van Allen Belts article. They can be trivial to lethal...

    I was suprised the current admin advocated a return to the moon.
