FYI: Mind how you go. We're more or less oblivious to 75% of junk in geosynchronous orbits around Earth

What a load of rubbish
Three quarters of the orbital debris floating among satellites in geosynchronous orbits around Earth is not being tracked, an astronomical survey has revealed.

The small bits of space junk identified by the study are often overlooked; they're faint, small, and in a region that's monitored less intensively than low-Earth orbit. As a result, scientists probing geosynchronous orbits above the equator found that the majority of debris located 36,000km out remains uncatalogued. That could be a problem – or more specifically, a danger – for any spacecraft placed in those orbits.

James Blake, first author of the survey published in Advances in Space Research said that the debris is probably from old bits of metal that have broken off from ancient satellites from collisions, or from fuel explosions. "We can take an educated guess on where the debris is coming from," he told The Register.

Research into deflecting potentially world-destroying asteroids is apparently not a…
