no one looks at it.

While Mars is too cold for liquid water, in the past, if its axis occasionally tipped over, the polar regions might have warmed above freezing during the summer.

I dont get this part. The water would have to be in another form other than solid at sometime during the history of this planet. It had to be very hot for some amounnt of time after its formation just like the earth but not quite as hot cause its a bit smaller. It still had to be hot enough the water was gas and then liquid. I thought the question would be how long did it remain in the liquid form before turning solid.

old article but still addresses the point. the existence of a liquid on mars at some point in the past is overwhelming and the likelihood it was anything but water miniscule.

sedimentary layers. outflow channels. don't forget that after this was written one of the rovers found carbonate formations that only form in the presence of liquid water.

Thanks for the article.
I was under the impression since mars has a smaller mass
it would not hold an atmosphere as "thick" as the earth.
It works like this on most other planets/bodies compared to the earth.

Damn I almost forgot. A couple of the moons around Saturn and jupiter show
clear signs that they are not dead "tectonic activity, hot insides" even though
they are small. Apparently it is thought that the gravity from the large planets
they exist next to pulls the heck out of the insides of these moons and somehow
creates heat. Keeps the molten stuff moving or some such idea.

And the heat I assumed would last longer from all the activity inside the earth just because it has more volume than Mars so it would not cool as quickly. I assumed it would be colder on the surface of Mars both because it is further away, but more importantly it has such a thin atmosphere it would not hold heat as well as the earth.

I am not an astronomy guy really. So thanks.

Ok the Martian soil sample taken today could sustain the
growth of plants. The right chemicals are there, although
it is slightly basic.

So we got water, we got soil. Enclose and have some
solar panels... looks like it gets more possible with each
finding that we could actually have people live there.

This would not be a vacation spot. 200 mph winds..
and very cold. But that could be taken care of with an
enclosure. We might be able to grow plants there for food.
A sustainable place.

I just urinated in my shorts.

you want water? why not live on the bottom of the ocean? cold? why not colonize antartica? i'll believe that we'll have people living on mars when i first see colonies of people living on the bottom of the ocean, or on the south pole. they're both a lot closer and a much more hospitable.

Party pooper.
Environmental groups are not going to let
you live in Antartica. They may let me, but not
you.

Actually if the population growth does not change
you might see both. No you wont. But your grandchildren's
grandchildren might.

antarctica may be a viable option in a few millennium.
