Just how bad is space junk?

Space debris is reaching plague proportions in space around Earth. This image shows the tracked debris in space around Earth.

Between the launch of Sputnik on 4 October 1957 and 1 January 2008, approximately 4600 launches have placed some 6000 satellites into orbit; about 400 are now travelling beyond Earth on interplanetary trajectories, but of the remaining 5600 only about 800 satellites are operational - roughly 45 percent of these are both in LEO and GEO.

Space debris comprise the ever-increasing amount of inactive space hardware in orbit around the Earth as well as fragments of spacecraft that have broken up, exploded or otherwise become abandoned.

About 50 percent of all trackable objects are due to in-orbit explosion events (about 200) or collision events (less than 10).

They will have to launch another couple of satellites to take out these junk satellites. A couple of high powered lasers to burn those relics to dust or maybe even find some way to blow them out of Earth orbit.

I think some sort of net or gel that can gather the junk and either burn it off in the atmosphere or push it off into space. Still it would be an immense job to do
