If we could get a huge ship, go to Neptune, snatch a lot water then dump it on Mars, would it be habitable?

Question

If we just had a giant ship, got the water dumped it on Mars, put some trees there would it be habitable? i know the trees would need oxygen, but if we could get it from somewhere, could we live on mars?

Answer 1

Neptune is made mostly of Hydrogen, Helium and Methane. Assuming you had a reliable means of transporting all that, it wouldn't do much to make Mars a garden spot.

Answer 2

Not likely, you still have to deal with radiation, and of course gravity issues. I'm probably forgetting some crucial things.

Answer 3

Neptune...why go digging into a deep gravity well such as that.  One would just need to divert a bunch of comets to get the H2O and organics and then a bunch of asteroids to help build up the mass a bit..take all those ones that are Earth-crossers and send them to Mars instead.

You wouldn't need a gigantic ship either; just use either mass-drivers or solar sails to divert these comets or asteroids.  Space mirrors could be used to warm the planet's surface to make it habitable.

Answer 4

ok Big B , it is too much work that way, think about easier way a simple one, a short time one, or a cheap spending money idea

Answer 5

If the question is simply whether it would be possible to make Mars habitable, I think the answer is "yes".  Mars is smaller than Earth, and it will always have a thinner atmosphere than Earth, but I think it could be engineered to support human habitation.

However, it's not as simple as just dumping enough water onto it.  People have a greater need for oxygen than trees do.  And "habitable" isn't quite the same thing as "comfortable".  If we do terraform Mars, it'll be a long, slow, drawn-out process involving many stages.

Personally, I hope we get around to it someday.  Right now, all the life we know about is on one planet.  That's the ultimate example of keeping all your eggs in the same basket.  I hope we have a backup planet before the next Dinosaur Killer starts falling our way.

Answer 6

It would take more than minor terraforming to make Mars hospitable, its temperature is too low for life

The average recorded temperature on Mars is -63° C (-81° F) with a maximum temperature of 20° C (68° F) and a minimum of -140° C (-220° F)

Answer 7

Probably not because Neptunes water is made/ mixed with different chemicals than our H2O, take for example the moon of Saturn Titan has oceans made of methane.

Answer 8

Neptune the undersea city?

Mars the candy bar?

Why would you need to get a ship,,, ok I see. you need a ship till you go under the water, but why to dump it on your candy bar.

OK you just got an interesting cause I realized I have a MARS bar on he kitchen counter.

DUDE way to go.

But right one... whatever floats your boat.

Answer 9

Yes, but try heat because they just officially announced there is ice on mars,so heat it up melt the ice  and let's go.
