[Realitycheck]

I have an idea for a way to collect space junk that our atmosphere is full of, one piece at a time. First, we start out with a command unit which will be capable of doing the majority of the work flying around to position itself to capture each item, towing the junk out of orbit, etc.. This will be connected to a large net of extra strong, highly elastic material that will absorb much of the energy of the orbiting junk. Around the net, you will have a small number of small, rudimentary pods which will be equipped with small thrusters to enable you to spread themselves out in a formation enabling you to catch the junk. All of the pods will need to be extremely strong in order to withstand the impact of high speed collisions. You will need a satellite(s) in orbit to be used as a home base to allow refueling. After each item is caught, it can either be towed out of orbit, or more likely into ocean landings. How hard would it be to tow an item into a freefall and allow the capture unit to escape the fall? Ion engines?

Anybody know of any strong elastic materials that function at 200 degrees above AND below zero?
