Possible 2014 comet impact to Mars could make it habitable.

Speculation here that such an impact could make Mars habitable:

Rush to Mars: Comet impact could make Red Planet inhabitable.

Not really, one comet can't bring life, water and a new environment overnight, it would take thousands of comets and take millions of years.

Habitable and inhabitable, they are used interchangeably, mean capable of supporting life. They are not used to mean inhabited.

Hmm seems a bit of a stretch. Interesting either way.

 

I have suggested elsewhere that Elon Musk may want to try to nudge the comet into Mars to make the planet slightly more habitable for his settlers.

 

A very large comet would create something of an "island" effect. The area around the impact would be warmer for decades, and the air pressure at the bottom of the crater would be significantly higher.

 

If it happens, and that's a big if, it will affect the environment of Mars, but not to enough extent to make it habitable to us. It would give us a lot of new data though, and that's one reason to hope that the unlikely will occur. But Mars is a small target in a big space. But we could get lucky, as it's happens before, here and there.

 

There is no author or source cited in the article. That means it's made-up nonsense.

 

Evidently your grasp of the English language isn't all that good. Those words are not like "flammable" and "inflammable" - they are the exact opposite of each other.

 

Not correct. Inhabitable is able to inhabit. The opposite of inhabitable is uninhabitable. Habitable and inhabitable are the same: http://www.merriam-webster.com/dictionary/habitable

 

You are quite correct, of course, thanks. Guess I shouldn't post while half-asleep.

I feel bad for future settlers on Mars, if such events are frequent. Even if this comet raises temperature of carbon dioxide atmosphere environment and melts the water ice and dry ice at polar ice caps, well if in 500 years from now Mars will have settlements and gets bombarded again...what good will it all do?

 

Such events are not frequent: the smaller the planet, the less frequent they are, so the risk is less than here.

Dry ice. Right. If a comet vaporized the ice cap, Mars would have a mostly carbon dioxide atmosphere, making it most decidedly uninhabitable.

Howdy....hello....Learn to move comets in front of mars and let it 'rain' manna.

 

Haven't seen all the post. So if im repeating someone, my bad...

Mars has had flowing water on its surface at one point in time, but it's core has stop making a magnetic field like earth has. With out this, life can't exist. Though, if you could have a constant liquid water on or in Mars, I'm quite sure single cell organisms can adapt to the extreme temperature fluctuations caused by the sun. So it's a small chance this comet will retain enough water and seeds for this life to start, but who are we to judge? We are here anyway...
So I'm on the side of, no. The chances are small, mathematically speaking... But there is always that vary small chance...

 

What will happen to the ant people?

 

Sure it can. Life doesn't need magnetism.

 

its not that life needs magnetism, directly anyway. The sun gives off solar flares, the earth is bombarded by these all the time, but your magnetic filed keeps ot from harming us or the planet. Our atmosphere would be striped away if we didn't have it, there for, we'd not only be with out oxygen, but we'd be hit by tons of radiation... Our magnetic field is a big part of our survivability here on earth, and on mars, same...
