How can we "terraform" mars?

Question

How would we go about making mars livable for humans and how long would it take? And do you think we should?

Answer 1

apparently in 20 years time the first manned space mission to mars will be sent out.
if no life is found they will begin a process of changing mars into the sort of planet we are able to live on.
they will inject greenhouse gases into it's atmosphere to raise the temperature.
the ice will melt into water and if all goes well in 100 years they will start planting trees which give off oxygen.
to change mars so it is just like earth will take thousands of years however. we should only try and terraform mars if no life exists on it. if life does we should try and help it to evolve and not hinder it in anyway.

venus is also a possibility to be terraformed by removing all the CO2 from the atmosphere which will lower the temperature and make it more livable.

Answer 2

yes we could terraform mars. to do this we would need to do exactly what we are doing to our own planet now,and that is we would need to place machines onto the surface of mars what would pump out vast sums of co2 gases. these greenhouse gas's would form a atmosphere on mars that would trap the oxygen molecules that would be released by the vast ice shelf's on the mars surface. we could not change the gravity field, and it would take a looong time, but the theory's right and should we do it if we could . IN ORDER TO SURVIVE as a species we must reach into the stars. just think if a asteroid hit earth now as you read this and life was extinguished the only living people would be the astronauts on the space station. Maybe we should all ways make sure there are both men and women on there.

Answer 3

Terraforming mars would be a large undertaking.
We would need to create and hold an atmosphere.
We would need to create and maintain a magnetic field.
We would need to supply water and volatiles.
it would be the work of centurys, probably starting with the engineering of some collisions, moving small earth & mars crossing asteroids, by means of solar sails into the planet, maybe dropping one moon in the process, to increase its mass, to try to heat the core by deformation, to shape ocean basins and adjust it's 'day`.
A comet or ten might be added to the recipe to provide the water and volatiles.
Unless the core heating succeeded, the next step would be the magnetic field. (You can imagine the problems there).
The final problem would be the engineering of a biosphere, starting with the comet volatiles: CO, CO2, NH3, CN, CH4, H2O, and producing something livable therefrom.
We are unlikely to muster the required resources,
but it was fun wasn't it?

Answer 4

We can not turn mars like earth but can live there creating an artificial atmosphere.

I have heard that the scientists have successfully created and artificial atmosphere in an desert which is propable 15-20 kms long. They are trying to duplicate it in mars. But the major problem they have to face is gravitation and the change of atmosphere. We can at most convert 50% of mars fit for living. But it would take more than 1 century.

The man is running out of space on earth. Now they are planning to make houses in ships. Japan has building a "sky city" which propably consists of 1,00,000 flats. It's a mini city.
With these many problems, we can shift into mars living the other species on earth to live without fear of man

Answer 5

Mars can´t be terraformed. It is too small to hold onto a dense atmosphere. Even if you could "dense up" the atmosphere it would escape into space. And hardly any nitrogen remains and nitrogen is essential to life. You´d have a better shot at terraforming Venus. Mars has many problems but the only problem Venus has is that it is too hot.

Answer 6

We would probably need lots of radioactive material to heat up the core of the planet. It would take a very long time, the truth of it is that we are just not ready to do this yet; maybe we will be ready in a few hundred years. Yes we should make another livable planet as soon as we can, we need the room.

Answer 7

There are two ways they could mean this. They could simply mean that the food was really good. It is a hyperbole for the food making them feel energized or something like that. It is a more polite way of saying something like "the food was orgasmic." The food did not result in a climax, but it was very good. If they literally mean a religious experience, there are a lot of religious ceremonies that involve food. This is because food gives us life. People tend to incorporate necessary life sustaining things like food and water into their religions because God gives us life. Without the food your body could not survive. Without God, your soul could not survive. What to eat? In the first case, just eat something really good. That all depends on your tastes and preferences. In the second case, it depends on your religion. Many faiths have some kind of food-based ceremony. However, just consuming the food and taking part in the ceremony does not guarantee a religious experience if you do not hold a deeper understanding. You also have to be in the religion. You shouldn't go to a Catholic Church and take the Host and the Wine if you aren't Catholic (but you can receive a blessing by crossing your arms and going up). Some people try drugs (not that I am suggesting that). Hallucinogenic drugs like 'shrooms, LSD, peyote as well as some kinds of alcohol and marijuana (to mild degree) have been used in religious ceremonies and have been known to have some "interesting" effects on the mind and perception.

Answer 8

By making the atmosphere more thicker to hold in more heat, so that the ice can melt and introducing biologicals into the water so that the life process can grow. Create some kind of oxygen machine to help the process of the whole thing.

Answer 9

yea its possible, but not rightnow, we'd have to weight a couple centuries for that kind of technology.

but right now since the weaher is way to cold and there is no atmosphere to protect us from uv rays and no oxygen. we'd have to kind of combine the sunand atmosphere intoone bymaking a shell aroundthe entire planet completely enlosing it. that would protect us from the harmful rays of the sun. and we will also surround the inside ofthe shell with uv lights and heat lights to regulate a good tempurature and to have uv rays sothatrrees can grow. then pump it fullof oxygen and other gas's we need. then put a couple thousand trees. make a bunch of artificiallakes. pretty soon precipitation would come and we would have a perfect planet.

well, its wishful thinking and I guess a good idea, but even if we did there's one major problem people DO NOT think about.

mars' core is not very hot and fluid, thusly since it doesn't move too much, it cannot create a magnetic field.

without this field any atmosphere we create will probably be blown away from the face of the planet, by the "solar winds" from the sun.
