Junk consisting of broken satellites and the like is becoming a hazard to new satellites. This idea provides a way of cleaning up an orbit ready for use by a new satellite. A giant ball of specially-formulated blu-tac is launched into orbit at the required height. The junk in the orbit is slowly mopped up as it collides with the blu-tac and sticks to it. Once the orbit is clear of junk, the blu-tac can be collected and recycled.-- prufrax, Jan 02 2011 50 lb ball of silly putty dropped from parking garage http://www.youtube....watch?v=uWYxc8xhihgwith spectacularly unexpected shattering goodness.

If you shot it up in a rocket, or railgun capsule, or space elevator car, or whatever, that's fine. Then you have a large lump of blu-tac, up there, inside of a container or capsule. My question is this: how do you get it out? I think it will stick to the inside.-- pocmloc, Jan 02 2011 // how do you get it out? //
Easy - explosives.-- 8th of 7, Jan 02 2011 I think the Blu-tac would freeze solid, rendering it less than useful. We should research liquid nitrogen-based glues. Then when the heat of re-entry melts the glue away, all the accumulated junk will separate and burn up in the atmosphere.-- gisho, Jan 03 2011 random, halfbakery
