    I seriously didn't realise there was SO MUCH human created debris up there!

    7500 tonnes is the estimate, and here's what someone thinks it looks like

    There's a new machine going up next year, the size of a washingmachine, to practice netting and harpooning the big stuff.

    Fair enough... cos what you don't want on the International Space Station, is a stone chip in the screen.....it's not covered by your Insurance and it WILL affect your no claims bonus in this case!

    Yeah, the amount of debris from our used up rockets and satelites we've managed to accumulate in orbit is really depressing. We litter our environment wherever we go.

    If that goes on for a little longer, then we cage ourselves on this planet, as there'll be so much debris in orbit, that we can't launch another rocket without crashing it in there.

    Can't we just hang up a sheet of fly paper. ;)

    That's basically one of the many ideas for clearing up the mess. Launch a craft with a large aerogel "flypaper" and use it to mop up. Bring the craft back down to burn up in the atmosphere. Repeat.

    Isn't that the gist of most of the plans... Round up the bigger bits of detritus by whatever means and then bomb it into the atmosphere and/or the ocean [if any of it survives reentry].

    True, though with slight variations in technique.
    I seem to remember that there are also plans to outfit the ISS with high-energy lasers to shoot down pieces should they present a threat to the station. Not sure if anything will come of it though.

    I would have thought something like that risked breaking whatever it is you're shooting at into lots of smaller bits.

    Speaking of space junk and i don't know how true this is but i seem to remember reading that things like satellites get covered in a thin film of human poop left over from Apollo program after a few years in orbit.

    As @Corky42 says, you then risk turning a large, easy [ish] to keep tabs on hunk o' space junk in to smaller, harder to track, bits of space junk.

    If that's a accurate representation of what it looks like up there then they've sure made a mess. Perhaps we will see a call for “health and safety” inspectors to float around in lower orbit in a not to distant future.

    Well, NASA should have a pretty good handle on it, after all they've contributed to most of it, if not all. It's impressive that they are able to track that many objects.
