Some scientists are saying that this new evidence may prove that mars may be habitable. Science News - Scientists believe Mars lander exposed ice crumbs

I was not found on Mars o_O

Even if we did manage to inhabite that place, we'd only destroy it all faster than we are this planet already anyway.

That may be true but It would take a long damn time to do that!

I thought they already knew there was ice on Mars? Why else are there polar caps?

And excellent article it could give us some hints on how Mars got it's watter in the first place.

I feel a David Bowie song comming on.... I thought this was the case, people believe if the green house effect occoured at a fast rate on mars it might just habitable, however I disagree to this as it hasn't quite got as strong a magnetic field, but hey we know very little about things like that :p

There are intresting things similar to both Earth and Mars. The Ice cap being one of them, being the presence of water. They both have tilts satelites evidence of impacts and even our moon has evidence of scaring, and both planets have a magnetic field.

I'm not sure if the "canals" on Mars are evidence of an abundance of water but perhaps a presence. If it can be determined what direction the water ran in perhaps a source could be isolated.

The relationship between ice and EM fields has always fascinated me. The occurence of Ice through out the solar system may not all be related but I think some of them...especialy here in the inner planets suggest a common event.

Water is actually extremely common in the universe, as it's built up from light elements (the Big Bang started out with the lightest elements and they slowly combine to for heavier ones). If Earth and Mars are special in a similar way, it is that they are both in the habitable zone of our Sun. Meaning they're in the area where it's not too hot that water vaporises and not to cold that all the water freezes. Unfortunately for Mars, it does not (or no longer?) have an atmosphere. So when water is heated on the surface is instantly vaporises and leaves the planet. Now, you can only find water in the form of ice on the polar caps and under the ground. It might be possible though, that there are underground resevoirs of liquid water. These could hold life.

The theory about the canals is that they were eroded by sudden floods. In a similar way on our planet, glasiers can be heated from underneath (by vulcanoes). Under the ice large resevoirs of liquid water will form until they reach a point where the ice breaks under the pressure, resulting in a huge explosion of water and a large flood. This is why the canyons on Mars are straight, unlike canyons on earth which twist and turn. The canyons on earth are eroded by little streams of water, but over very long periods of time.

The Magnetic fields are generated by the planet's rotating core. Just look one planet beyond Mars and you'll see that it has nothing to do with water. Jupiter has an immensely strong magnetic field. If you could see it, it would appear three times larger than the moon in the night sky.

I heard the ice on Mars is formed from frozen gas. 0_0

Oh no, Lightning. You misunderstand. I'm not saying water creates strong magnetic fields. I'm saying where you find water you find strong magnetic fields. Aside from debris from the oort cloud (including Pluto).

Earth, Mars, Jupiter, Saturn, Neptune Uranus all have very strong magnetic fields and Mars, Earth and Uranus have water associated with the magnetic poles and Jupiter, Saturn and Neptune all have rings with a Roche limit far from the planet's surfaces. Another intresting corelation is the planets with large amounts of water have tilts. Mercury and Venus have little to no tilit a long with Jupiter.
