I understand that frogs are made up of a plethora of different molecules, all of which are relatively easy to account for as most if not all are known. Hurtling through space however, you would have no idea what you would encounter. Using that process doesn't the electromagnet need to adjust in order to account for materials of different composition or is it simply able to repel all things with no adjustment but varying degrees of repulsion? These are the only two possibilities i see physically possible, both pragmatic for space armor application. Minute adjustments would be impossible at high speeds and varying degrees would mean some things would likely collide with your ship because the magnet doesn't push them away enough.



Are we 100% sure that the soil composition of mars can not support plant life?

Obviously without the implementation of a pseudo-atmosphere to contain oxygen it wouldn't be possible but we could easily build agricultural hubs into future colonies provided the soil can support life, or even be made to support life. Or just haul a barge/compartment with some amount of workable soil. With enough additives and some sort of compost system soil could be maintained for a long time. Indians grew corn in sand by planting a dead fish beneath the seed, otherwise the soil wouldnt have supported the plant. Same concept, different planet.


You raise a good point actually. To plan a one way mission, I'm sure this is one of the first things tested. Interesting with the corn seed and dead fish method.

Thanks for the insight :)

How about solar energy and the temperature, though?

I do believe that a diet on Mars would be very different to Earth still ... And not in a good way either.

Any agricultural pod would need to be controlled for temperature, oxygen, etc. We can easily supply oxygen, easily bring along plant seeds, and easily manipulate sunlight. However without a good balance of the 3 the plants wouldnt be super successful. Of course mass fertilizers can make up alot of the difference. My guess is any crops like corn would be placed into a processing machine to ensure 100% of the crop is used and the rest is turned into compost for future crops. So alot of the food would be made from things like corn meal and soybean paste as a base, yuck!

do you guys think is possible to ever move a small planet/moon?

Possible yes, Plausible no. Are you asking for the application of moving a small planet/moon into earths atmosphere/area to use as a satellite base?

Interesting idea i suppose. But the logistics of moving something from that far (few if any likely candidates within our solar system) would be unreal. Not to mention you would need to calculate a route that missed other large gravitational pulls or you may be pulled into another planet's orbit. (perhaps one with a pull to strong to avoid)

Two things i wanna mention:

1. Hydroponics - you don't need soil to grow things.

2. Composting - don't you need microbes which are overly abundant here on earth but not even existent on Mars?
Might be a huge challenge. I guess you could use human waste one's, essentially the ick factor would need to be eliminated. <----another pun.

hydro works great for small applications or certain crops. Im not sure how well hydroponic corn would work on a large scale

ya the compost would need to include human waste. or i suppose a supply of the microbes to get it kickstarted.

no doubt, in the future might be able to move a small moon from jupiter somehow into the habitable zone in our solar system, im sure on of them could potentially be habitable

I wonder how much a moon in space would weigh? And after figuring out the amount of force it exhibits orbiting around a planet you would simply need an opposing force. Caculatable? - probably, doable - not in a long time.

But it actually might be more feasable then trying to colonize mars - were talking 100s of years in the future - certainly worth Nasa discussing it as few Scientists have a clear vision as to their goals.

There is only one problem. The force required to steal a moon. It is somewhat feasible to move the moon if no major forces of gravity are acting on it. To pull it away from a gravitational body like jupiter however seems fairly impossible. I mean it could be possible but beyond the scope of physics we currently understand, i cant see any existing or even theorized technology accomplishing this.
