Apologies,,Secret,you were not talking to me.

Building a dome on mars is so,so,so,damm easy to SAY.
The best we can hope for now will be living inside inflatable boxes,with air locks,to come and go.
The 'Russian Grunt' (Phobos,landing) program seems to be the only long range Mars Landing Program,,we currently have in the works.Mars does NOT have a breathable atmosphere,perhaps in the low,low lands,,of deep under ground.

FOR THE FUTURE:::

The machinery built on earth for earth evacuation would do wonders on Mars,,lesser gravity.

Actually, there is some evidence of glaciers presently on Mars at low latitudes:

[link]

Ice can be used as a building material, think of an iggloo on steroids. As long as the temperature never rises above 0 C ice behaves very much like stone. Imagine something like St. Peter's cathedral, but made of blocks of ice instead of stone.

Of course you can buid a dome on mars.

Abnd, actually the temperature DOES rise above 0 c, but as long as it gets colde enough at night that the AVERAGE daily temperature does not rise above 0 c for too long, we are still fine.

I guess if you can;t think outside the box, you have no choice but to consider lving in one?

Ah,rlewis,,,you are correct when you say"Of
course a Dome can be built on Mars,,with Ice."

I was referring to the constant portrayal of large transparent domes on Mars.This is a Science Fiction concept,not reality.

Although,,,I suppose someone could mention ice is transparent'.,,,

rpage,,,What a really great idea with the ice blocks (or spraying water onto a suspended form,freezing instantly),,,is this by chance an Original Idea?? Quite Good.

Sorry to rain your parade here.
As I understand it, pure or nearly pure O2 by itself is not sufficent to breathe. On earth we breathe a mix which is primarily Nitrogen 79% and Oxygen 21% at a total pressure of 1 bar. As far as I know the Nitrogen is inert to our bodies, it just acts as a dillutant for the Oxygen. Although at higher pressures any scuba diver will tell you the Nitrogen pressure will cause a 'drunken' effect called Nitrogen Narcosis and if the pressure is reduced quickly the 'inert' nitrogen can form bubbles in the tissues and circulation leading to effects called the bends. Breathing high oxygen concentrations causes chronic oxygen toxicity, mainly respiratory discomfort which can be relived by dillution of the oxygen, while if the total partial pressure of oxygen exceeds 1 bar (even when diluted) acuate oxygen toxicity sets in and causes fits and unconsciousness.

Management of the breathing mix is a little more difficult that just filling a cavity with oure O2 even if is produced by plants.

That's a good theory, but the problem is, of course the money. But it is possible, if you could make the oxygen. But, of course you'd have to construct an artificial atmosphere to hold on the oxygen. But good theory Cool

I seen a Mars documentary on YouTube saying that several dozen hydrogen bombs dropped on the
Ice rich poles of Mars would warm up Mars by 10 degrees which would start a chain reaction of
the release of vast amounts of carbon dioxide into the atmosphere thats been locked up in
the soil all over Mars and the glaciers and permafrost would melt into vast oceans and lakes of liquid water
literally over night making the atmosphere sufficient to allow astronauts to discard their spacesuits and
only need to wear oxygen masks like what they needing on 'Pandors' in Avatar! Razz

Robert Zubrin said Mars can hold onto a thick atmosphere for at least 100 millions years and human activity would replenish it forever! Cool

Human History is 10 thousands years old so 100 million years is an eternity to us!! Laughing Very Happy

now go Lobby Congress to get this done A.S.A.P. - LMAO Shocked

Hawkins...

The lack of gravity would kill that deal, don't you think?

The low gravity may lead to interesting evolutionary effects on the human body in the long run but is certainly no show stopper for a dense atmosphere.

MPJ>>>>!

On behave of all of us here on the MRB>>>this 'lack' of gravity was discussed many years ago...and for your information, check out via research the Russian cosmonaut who attempted more than 500 days in 'no-gravity'. You would not have wrote a 30 above.

do you think mars have core crust mantle like on earth if he dont have its very nice to live there cause we dont need to worry about on the volcanism because if earth dont have it no volcanic eruption gonna am i right??? Very Happy

but the higher the gravity the higher we can jump so we need exact gravity like on earth gravity do you think mars have some exact gravity like on earth?

I was wondering, is it in any way possible to convert rust (iron oxide) into iron and oxygen. Because, if it was, since most of Mars's surface is rust, you could launch a bunch of solar powered robotic rovers. The robots would have a dual purpose: as they moved around the would gradually compile a detailed 3d map. Meanwhile, they would take in the iron oxide and convert it into iron (which is obviously useful to anyone who might temporarily/semi-permanantly settle there) and...dun-dun duun! oxygen. I think this is possible with reverse...or is it standard...electrolysis.
