Odd finding this thread looking for "oxygen candles" but if you want to know how to give Mars an atmosphere and make it "stick" it's simple... atmosphere based on at least 50% Sulfur Hexafluoride (search "anti-helium").
It should react as nitrogen does in Earth's atmosphere but unlike nitrogen, it's heavy enough not to blow off into space.
Now comes the fun part... how to fill a planet with enough sulfur hexafluoride. Shocked

"What if" we, as the human race... indigious to Earth... were to detonate a few hundred atomic bombs in the martian atmosphere, wouldn't this release the oxygen stored in the CO2 dense atmosphere, soil, and dry ice???

With the temp on mars, it would be impossible to grow typical plants on mars. We would have to genetically mutate evergreen trees to withstand colder temps. Also, plants give of co2 in the dark. I don't see the need to bring the so-called 110% theory into play. You would just need to have an equal amount of air comming in the dome as going out when there is light present.

Is there an easier way? Can we create conditions on Mars that would generate Oxygen the same way it was originally generated on earth?

I haven't read all of this blog.. But i had a eureka moment..

Ok so we know mars has an atmosphere.. Not like our own.. But if we're going their we'll need bio suits but what I was thinking was... Instead of carring bottled of oxygen whatabout having something that can alter the atmosphere in our favour..

We know passing air over a current changes it we have it in ionisers.. And in aquarium ozone generators .. So is their away of transforming the elements in the atmosphere to be more beneficial to terrains..

I guess you're right. I had your exact same idea! Very Happy Very Happy

There are ways we could make Mars more habitable.
1) Provide an artificial Magnetic field. A nuclear powered electromagnet that could produce an intense magnetic field could be located on opposite sides of the planet, one producing an intense north and one producing an intense south field. The magnetic field would penetrate into the iron core and re-magnetize it after a few hundred years. The Earths magnetic field is 25 ~ 65 micro Tesla so if we constructed something that generated 1 ~ 2 Tesla then let it run for say 100 years we would have re-magnetized Mars.
2) Using drones we drop a black powder on the ice at the poles, something like soot or a carbon rich material. this would increase the temperature there and cause the C02 to sublime back into the atmosphere and perhaps start to melt the H20 so it flowed back to the equatorial zones. Granted this would take a few centuries to do but eventually the atmospheric pressure would increase again enough for water to exist without it sublimating.
3) There is an enormous amount of 02 locked up in the rocks and soils on Mars. NASA already has a machine developed that can release Oxygen and Hydrogen from the soils to manufacture rocket fuel. We could build many of these and release the products back into the atmosphere to give us a breathable atmosphere. Humans can exist in a lower atmospheric pressure than on the Earth. Here it is 14.7lbs/sq in or 1 bar in metric. If we were assume that we could create a global air pressure at sea level (assuming we had made some seas Smile ) 0f about 10psi (10,000ft on Earth) then humans could exist at this level. It's interesting to note that a private pilot can fly his plane to a max altitude of 10,000ft before needing Oxygen safely, so this air pressure is quite acceptable to us.
All of this would take about 500 years to achieve Mars as a place humans could walk without pressure suits and breath the air.
Oh, assume Mars is a dead place cause if not we humans might get into trouble with the extant Mars lifeforms taking over.
Thanks for reading !!

I am not able to value your facts, because i have no engineering background, but it sounds plausible en desirable!

The partial pressure of CO2 in the atmosphere of Mars is actually higher than on Earth, so plants could grow there now if they were kept warm enough (like in a greenhouse).

The fast way to partially terraform Mars might be to redirect a comet so that it smashes into Mars in a place where there are buried glaciers of water-ice. Steam in the atmosphere would be a potent greenhouse gas.

I am no scientist but always wondered if microorganisms could be sent to mars instead of a tree. I was looking around the web and found this article.


NASA is already looking into it.

I think we are forgetting the major difference between both the atmospheres and that is the amount of N2 gas. I think the equipment to test the lungs or PFTs which is in use to test the human lungs can help to recalculate the possibility of adequate human breathing on the Mars. There are tests known as N2 washout, DLCO etc. In my opinion we should look for the difference of N2 on both the atmospheres not the difference of CO2 which is easily manageable.
