Mars - why we're there.

I'll have to dig up the atomic weights of the gases we need to have a breathable atmosphere, but it may be possible for Mars to have an atmosphere, but one that is not very thick.

Hydrogen is the main key as it is needed for water.  Oxygen is probably heavy enough, but it can be calculated.

80% of Earth's atmosphere is within the first 8 miles of Earth's surface.  78% Nitrogen, 21% Oxygen, ~1% Argon and other gases.  

Radius = ~ 4000 mi + 8 miles = 4008 mi = 6.45x10^6 meters.

Total Volume (earth + atm) = (4/3)pi*r^3 = 1.04235x10^19 cubic meters.

which = 1.04235x10^22 cubic decimeters (litres).

(1.04x10^22 L) / 22.4 (L/mole) = 4.64x10^20 moles

With 78% N2, 21% O2, and say 1% Ar, with atomic weights 24.02 g/mol, 32.00 g/mol, and 39.95 g/mol respectively, we can calculate the masses of each group in earth's atmosphere.
[list=1]8.70x10^21 g N2
3.12x10^21 g O2
1.85x10^20 g Ar[/list]
^ All that is Earth.  I did that very quick and it isnt very accurate... now just convert it to Mars dimensions.  3387.5 km radius.  Radius earth = ~6437 km.  Mars is 1/10th (.107x) the mass of earth.  Mass earth = 5.9742x10^24 kg.  Mass Mars = 6.39x10^22.

The acceleration due to gravity at the surface of a planet varies directly as the mass and inversely as the square of the radius.  

Sooo... I gotta run so I can't finish.  Just throw that on Mars and see if it sticks  lol.

Like Skuzzy said, if an atmosphere is to be created, it would be thin.  But, how thin?

We are there becuase our tax dollars are like monopoly money
to the government and NASA.

A big freekin waste if you ask me.
We have kids in our own country starving to death.
We have kids in our own country going with out a proper education.

But we always find money for this BULLCHIT

its cool to just gaze at the pics from mars,,and wonder how it would be to walk there some day,,,or see the highest mountain in the solar system,,,think its 100,000 foot tall or more,,,or them canons that are 300 miles deep,,that would be one long fall,,lol,,and thats cool about mars mass,,sure is a dence little rock aint it? <~~very cool info skuzzy


when your talking about a mars probe,,sure it cost alot of money<~~but if we lisined to everyone about money cost of exploration we would still think the earth was round,,,you got to explore,,its in out nature plus its fun,,would love to see titian or any of them moons,matter of fact im lookin into getting a dobsonian telescope 12.5,,300 pounds,,lol,,sure big waste of money,,,but i will enjoy it,,my own way of checking out space,,cant wait to take some pics:)
