Rain on Mars?

[Tristnichol]

I know that there are canyons and dry river systems on the surface of mars, but did it ever rain there?

[Qazaq2001]

It is possible that it may have rained on Mars in the distant past, if the theory of a warm and wet Mars holds out, but the jury is still out on that. Q

I read somewhere on the NASA website that there are huge frozen bodies of water under the surface of Mars near the poles. Isn't that awesome??? Do you think we will ever colonize another planet or moon? ^_^
