Wow! NASA has found a bit of frozen water on Mars, like about 2,900 cubic miles of water volume. And...........this specific water ice found on Mars is only 3 feet to 33 feet below the surface of the soil!!
Could we just presume that this Lake Superior volume of water simply is a precursor to many other water-finds to come??

Hmmm, let's see, next they will discover that Mars does have a breathable atmosphere... then indigenous animal life...

So mars now has a magnetic field then?
Otherwise all that water would burn off.via uv and evaporation.

No. :)

It's ice, so they can put it on their whiskey. ;)

Makes you wonder about a lot of the "facts" about Barzoom,er, Mars, doesn't it...

OR
They could activate the big Alien machine that turns the ice back into atmosphere :P

No but why does it need one? :P Why do hu-mons make assumptions on how the Universe works based on one little old rock?

What if they are WRONG?
How Vital Is a Planet's Magnetic Field? New Debate Rises(http://www.space.com/images/i/000/008/759/original/aurora-solar-wind.jpg)
Solar wind particles generate the aurora phenomena in the Earth's atmosphere.
Credit: NASAQuoteOur nearest planetary neighbors, Mars and Venus, have no oceans or lakes or rivers. Some researchers have speculated that they were blown dry by the solar wind, and that our Earth escaped this fate because its strong magnetic field deflects the wind. However, a debate has arisen over whether a magnetic field is any kind of shield at all.
The controversy stems from recent observations that show Mars and Venus are losing oxygen ions from their atmospheres into space at about the same rate as Earth. This came as something of a surprise, since only Earth has a strong dipolar magnetic fieldthat can prevent solar wind particles from slamming into the upper atmosphere and directly stripping away ions.
"My opinion is that the magnetic shield hypothesis is unproven," said Robert Strangeway from UCLA. "There's nothing in the contemporary data to warrant invoking magnetic fields."
Each of the three planets is losing roughly a ton of atmosphere to space every hour. Some of this lost material was originally in the form of water, so this begs the question: How did the planets end up with vastly different quantities of water if they are all "leaking" to space at similar rates?

Seems that other scientists are discovering that we don't know everything yet :P

Facts are always changing as new data is discovered Don't be silly

Agreed; nothing is set in stone, and on any given day something seems to appear to tilt the academic apple cart and disrupt their "facts" on a regular basis...
:P

the question was sorta bait,earth has a larger radius but an atmosphere under pressure,the other two supposedly dont.
the closer to a flat surface,the more uv hits it.
imho,all things have a magnetic field so all the planets should have an atmosphere.otherwise the vacuum of space would evaporate the ice faster.
robo needs to do more research.

May I suggest starting with Enceladus?
That moon is supposed to have no atmosphere, is a big ball of water ice, yet has GEYSERS of water..

I haven't finished that one so if you research and post it I can put it on the website
