It's time to roll up the sleeves boys and girls, gonna have to put all the fun and games away for awhile. We should be shooting up a tug boat into low orbit, rockets on the stern, a big u-shaped magnet on the bow. Start picking up all the garbage, somebody's got to do it. Reminds me of Mt. Everest, the
worlds highest trash dump.

The article is actually talking about the space debris left by a future space war, not what's up there already. [DrCurry, Aug 24 2002, last modified Oct 04 2004]

Aren't space stations and satellites made of metal, too? |
|

Calum: Yes. And the debris is largely non-ferrous alloys (because they're lighter) so a magnet won't work on them. A net would be better. |

Croissant for the idea, fishbone for lack of research = neutral vote. |

I believe there are items as small as a fleck of paint that cause damage. need a fine net. |

The concern for a chain reaction. If all that stuff starts crashing and bashing ad infinitum, forget about sending anything through it for a while. [see link] |

Did somebody say *Satellite*? |

Zero chance eh? Well, what's in a comment anyway. The formulas get updated continously, calculating the odds. No impact on our lives? Out of sight, out of mind then, it's a good thing we can't see all the stuff that we breathe in every day, or another considerable effort would have to be made to try and clear the atmosphere, wait, isn't that being done? |

Of course there is no such animal as "Zero Probability" in science, but there is such a thing as "as low as any reasonably informed person might expect". There is no field of human endeavor that is risk-free. Benefits and risk must be calculated and weighed against each other. Of course this includes getting up every morning and going to work. Your chances of a heart attack from traffic stress and smog inhalation or a plain old-fasioned car wreck are considerably greater than those of space junk rain, and will remain so for some time to come, I'd be willing to wager. |

Actually the funniest version of this that I've heard of was proposed in all seriousness: a giant inflatable satellite. The idea was that debris would hit it and the orbit of said debris would degrade causing it to burn up on atmosphere. Presumably retro rockets would allow you to boost the giant space jumping castle to different orbits. As an added bonus, companies could have their logo painted on to increase product appeal to the nerdy telescope types. |

the military currently is developing anti missle systems using a "Laser." using this "Laser" from space (say only a short range "Laser" to not scare the rest of the world) on a small unmanned ship that flies around looking for junk, we could turn the space debris into space dust. it would also be an excellent way to test out "Laser" targeting methods in space. ---------now who wants to be the space mechanic sent up to fix the "Laser" when it malfunctions and starts shooting randomly? any vollunteers??? |

In the ben bova book "sam gunn, unlimited" they launched a giant electromagnet to push the trash around. The theory that it worked on was that as the object orbited through the ionesphere it picked up a negative charge, so just hit it with another negative charge from an angle would deflect it into the atmosphere. I tried to figure out Maxwell's theorom (one of them) to figure out the newtonian force needed and amount of energy required. Alas, I lack the skills. |
