Water On Other Planets...

[Jelly]

Just an idea I thought of whilst doing some homework (Which is completely unrelated to this) because I was bored..

Couldn't we just send some people over to a suitable planet and empty some water there, and keep doing it until there's a lake or something? They could use seawater or something... perhaps. Then we could all go live there when global warming gets worse. Maybe?  ??? I don't know, you'll all probably find a hundred things wrong with it, but still...

Starting with the atmosphere. They have to find a livable planet first. If water was the only concern we could all go live on one of the moons on Jupiter.

[Mashiara O Aan.a--ein]

hmm......but the gravity and atmosphere would be all wrong and we'd have to live in space suits and whatnot.....and our bones would get all messed up....I'm not sure what they would do for food

 

still..call me if they ever dump the water on that plant :)

The main problem to both these is gravity. Either too much (eg Jupiter) or too little (eg Europe - that's the moon Barmy means).

[Alys Kinch]

europa. atmosphere, gravity, then water and wildlife. the ages it would take to introduce what we could would take way more time and money than we have to invest as of this point, methinks.

[Jelly]

Ah well... who needs gravity?  :D

I would like to fly.. (Which we could do without the extra gravity.  ;D)

The water would be able to stay on the ground somehow. Someone would figure it out.

And if there were oxygen in the atmosphere (most likely to have come from photosynthesis), the life on the planet would probably have other amino acids than we are based on. So we couldn't live there anyway.

[Thorum]

we can create a fitting atmosphere (at least, let it be created by bacteria, algae and plants). But it would take about 200-250 years (this has been tested), and the gravity has to be correct, so it wouldn't just dilute into space.

[Nightstrike]

Didn't it take 1-2 billion years for all the iron in earths sea to bind up all the oxygen that was produced by photosynthetic organisms? Seems like it can't be done, if there are iron in the planet's seas.

[Thorum]

that were a couple of bacteria.

 

We can invade the planet by zillions of plants and algae and bacteria. (the limiting factor for their growth is SPACE on Earth)

We'd have to find a planet in whats refered to as the 'habitable zone' with respect to the mother star.  mars and venus are on the edges of our suns habitable zone, where earth is right smack in the middle.  as previously mentioned, we are evolved to live on a planet with the gravity that earth exerts.  moving to another planet with similar mass would be no problem, but finding that planet would be tough.  we're also going to need to find a planet that still has a molten core of mostly iron so it will have a strong enough magnetic field to keep solar radiation from just destroying what atmosphere is there, ie. mars.  its not just water we are looking for.  for humans we need another earth.  we pretty much need the exact same conditions that we have here to survive normally. 

 

in the end its more practical to stop driving giant boxes around, to find some cleaner renewable resource for energy, and to convince people that if they do not have the necessary recources to take care of a child, that they shouldnt have children.  reduce emission of green house gasses, and more rigorusly control the population.

 

fun fact!  we have found an extra-galactic planet that is composed primarily of rock and water.  the fun part comes from the fact that the water is "ice", but only from extreme pressure.  the planet is pretty close to its mother star so its not cold, but it has so much mass that the water is solid.  its "ice" but its not cold.  weee!  fun with science.  i forget what the planet was called, but watch "the Universe" series on the History channel.

 

But honestly its more plausible to make space colonies like in gundam, or to create stasis boxes and fly to another earthlike planet in some other galaxy, than to try and terraform another planet.

[TurboZ]

Isn't the core of our planet mostly nickel with the inner core being solid and the outer core being molten? I was sure that was what caused our magnetic field.

[Jelly]

Whatever would we need a magnetic field for?  :P

[Thorum]

to let most asteroids bump away.

 

Or the thing that happened 65 million years ago would happen yearly or something like that

[SqueeEGA]

The magnetic field keeps solar radiation from burning off our atmosphere.  Mars used to have a magnetic field relativly strong compaired to ours, but its core wasnt large enough to stay molten like ours, so its magnetic field was deminished, resulting in the mars we know today.  Our magnetic field keeps the sun from burning away our ozone.  It does a bunch of other stuff i dont know. 

[Tenshin_Xo]

It doesn't affect asteroids.  It really only interacts with charged particles, mostly from the sun.  It does stuff like cause aurora displays(which high densities of particle emissions from the sun) and make compasses work.  It also makes it possible to find iron ore using disturbances in the field.

 

There was some new variation on dynamo theory thats a year or less old, I haven't looked at it yet, but have heard that it's interesting.
