Another idea to handle space junk


This current idea is to strap a small rocket engine to it, and then de-orbit the piece of space junk. It might work for big chunks of junk, but I don't think it's feasible for all the little pieces of stuff up there.

'Housekeeping' could solve space junk mess

And the basic idea is:

The process would involve launching a specialized satellite that would rendezvous with the largest examples of space debris, like spent rocket bodies, and attach a small propellant kit that would nudge the junk toward Earth's atmosphere where it would burn up harmlessly, the BBC reported Tuesday.

The scheme could inexpensively remove five to 10 such objects per year of operation, the authors of a study published in the journal Acta Astronautica said.


It does make sense to take down the big pieces so that they don't run into each other and hence makes lots more little pieces.

Now, the alternative below won't work now because the Space Shuttles are done flying. And the inner layer of the junk-catching can would have to be made of some pretty strong material to resist puncturing in a collision with something moving several thousand miles an hour. But I'm just being a pragmatist.
