So we now know there is water on mars. my question is how did it get there?

Question

would it be the same way many believe it got on earth (on a comet that had water on it)? or a different way?

Answer 1

the same way water got here on earth, a comet brought water  and the elements that would later compose us

Answer 2

could be many different ways, comets, chemical reactions, or it was a dumping station for wandering aliens in their intergalactic RV's. They are still studying the evidence that Mars used to have an atmosphere, and a magnetic field protecting it from the cosmic radiation, which could have led to an atmosphere at one point. I tend to think it was likely comets though, as they are mostly ice, and in the early stages of the universe, it was a galactic shooting range with comets, and planet sized rocks colliding everywhere, they have also found water on the moon as well, so water in space is not going to be an oddity like they once thought it would be, I feel its going to be very common. I do however think any kind of life beyond microbial is going to be extremely rare.  

Answer 3

A pregnant martian was about to give birth?

Answer 4

humidity?

Answer 5

well there is a big honking polar cap made out of mostly water ice a few hundred kilometers away from the phoenix site... maybe that has something to do with it?? I don't see why we're all supposed to be so impressed quite honestly. the site is almost within the extent of winter surface frost if I remember correctly. I don't think anyone who knew something about mars beforehand will be too surprised by this.

Answer 6

Probably comets, then preserved by mars' surface.

Answer 7

it rained

Answer 8

water is h2o. h2o is two hydrogen atoms and one oxygen atom combined to make a waer particle. i beleive that when mars formed, it had oxygen and hydrogen. it combined to make water. scientists know there was a lot of oxygen and water on mars because te iron mass of itis rusted. for rust to form, the iron must be submitted to water and oxygen. i beleive hat mars ws to far away from the sun to sustain enough heat for life. that is why there is no life on it today.

Answer 9

The same way we have water here.

It seems likely that at some time a long time ago Mars may have been more habitable than it is now.  Mars is smaller than Earth and it's core is no longer molten.  Since the core cooled it has taken away the magnetic field and allowed the atmosphere to drift off into space.  Any exposed ice will escape into space through sublimation.  The fact that Mars has so much ice locked under ground shows that it may have been earth-like a long time ago.

Answer 10

Water is actually fairly easy to create.

First, you need hydrogen, and oxygen. Both are in compounds all over the place, and a re all over the solar system on the diff planets.

Now, burn the Hydro and the oxy, this will produce water.

Now, H an O can easily be generated from a number of chemical reactions, so not much difficulty there to get water.

But to sustain life you need atmosphere, which is why currently, there appears to be no life on Mars.
