Up in the Low Earth Orbit, anywhere between 160 and 1,000km above ground, is where about 4,500 satellites operate for geo-imaging and telecommunications purposes. 

But while businesses are launching satellites into space, no one takes ownership for clearing up the debris of old satellites, increasing the risks of them bumping into one another in space.
