Asteroid mining

Space mining is presently insanely expensive, at least partly because you need to lift your fuel all the way with you. So now the plan is to capture asteroids, extract water, convert this to hydrogen and oxygen, and stock it at an orbiting fuel depot, thereby making space mining viable.

Well, that's the plan.

I approve, although I am quite doubtful that it will ever actually pay for itself, if they can actually make it all work. It's worth a shot, and it might even lead to an awesome interplanetary future.

Cool idea but first some body needs to clean up the junk flying around this planet , they could sort , compact and send it to the moon in compacted chunks , designate a grid square or 4 for the impacts , and you have a scrap yard to work from when we finaly colonize the moon

If James Cameron has something to do with it it's going to suck eggs. Two thumbs down your asteroid.

I hope they don't abandon the Space Elevator idea.

I agree.

The valuable stuff "in space" at the moment is water for its usefulness as fuel and air for people. And because it's heavy and it's already up there. With the development of a space elevator the cost of getting heavy stuff up there, into orbit will be much less. This will be an enormous boon to space traffic.

Sounds great. I'm in.....

Let's put numbers to it. Only speculation says platinum or iridium are in asteroids. A rich deposit is maybe 2% of the material. It costs about $0.5 million just to transport seven gallon of water that far up. Add more expenses to take the energy out of something doing in excess of 17,000 MPH so that it can land. How many dollars is a pound of platinum worth?

The space elevator is nice in theory. Meanwhile the promising technology is to replace rockets with planes. So use oxygen in the air rather than carry it. To use wings for lift. As demonstrate by Rutan? when that group won an X-prize.

So a mining colony is setup on an asteroid. Then the colony survives and mines until the asteroid returns from its long orbit. To send a package to earth. We could not even keep a Martian Rover running through a northern Martian winter for a full year. The proposed task is daunting - even if something worthwhile exists to mine.

It is only a proposal along with another 10,000 that were equally viable and only based in speculations. But would make a good science fiction murder mystery.

Better get rid of terrorists first.:(
