What would it take?

Question

To create an atmosphere on mars so It can support water on the surface and harbor life?

Can't we just suck out all the dangerous chemicals and extra greenhouse gases and send them to mars?

Answer 1

ya good luck on that... it would take a LOT...

Answer 2

There are several problems here.

The first problem is the temperature on the planet.
When it is daytime the temperature can be "livable" It is still very cold, but not much worse parts of northern Alaska and the Arctic when the Sun is out.
When it becomes night the temperature drops so low that it would be impossible to support any forms of life as we know it, unless another heat source is found.

The second problem is the thin atmosphere, which is very low in O2 content.
Because the atmosphere is so thin, it does not filter out much of the Sun's radiation. The magnetic fields that may be present would be very weak compared to Earth's and would not deflect very much of this radiation.
It would be very hard to terraform the planet because the thin atmosphere would allow lighter gases to escape.

Because of both of these problems the only way to support life on Mars would be with Biodomes and Hydroponics.

There are other problems as well. The soil is most likely deviod or at most have very few nitrates, which plants need to survive and grow.
Nitrates could be transported from earth and recycled from waste products.
Gravity is lower, plants would need to adjust for this, and humans born there would have a very hard time goin back to Earth to live. They would not be used to the heavier gravity, and may not have as much muscle mass.
There are other problems, most can be taken care of with technology.

Answer 3

Mars can't hold an atmosphere just yet. First we'd have to restart its core, which would take more money and technology than we have at the moment. Without the core there can be no magnetic field, and people would not be able to survive. The atmosphere would be blown away by solar winds without this core activity.

However, there are several other places with active cores suitable for life. Just not humans. Europa could sustain our fish and undersea plant life. Titan, if warmed up, could harbour carbon-based life forms with a little extra help.

Answer 4

Not hardly...

it is a matter of huge, massive, volume versus drop- in- the- bucket changes by one man or group of men.

Mars is also farther from the Sun than Earth is, so it will always be colder there than here. Martian nights and winters are blisteringly cold -195 degrees f. Also, when Mars swings closest to the Sun, it receives 45 percent more solar radiation than the Earth does. That radiation includes X RAYS, GAMMA RAYS, as well as UV and Infrared light.
Without a space suit, you might survive on Mars for about 10 seconds. you would never be able to do that on the Moon, Mercury, or Venus.

Answer 5

there might be an atmoshere there now. There might also be plants and cities..animals. research ..mars structures...

Answer 6

there might already be LIFE there, not human life. it could be other weird things....we will never know till we are brave enough to see!

Answer 7
