Rogue (satellite) hunter

Things are going to get a little busier up in geostationary orbit… not only are there destined to be an increasing number of broken satellites cluttering up this important orbital region, but soon there’ll be little robot repair bots flying around up there trying to fix them (or push them out of the way):

Their robots will dock with failing satellites to carry out repairs or push them into “graveyard orbits”, freeing vital space in geostationary orbit. This is the narrow band 22,000 miles above the Earth in which orbiting objects appear fixed at the same point. More than 200 dead satellites litter this orbit. Within 10 years that number could increase fivefold, the International Association for the Advancement of Space Safety has warned.

Klaus Landzettel, head of space robotics at DLR, said engineering advances, including the development of machines that can withstand temperatures ranging from -170C (-274F) to 200C (392F), meant that the German robots will be “ready to be used on any satellite, whether it’s designed to be docked or not”.

Hellooooo, orbital commercial warfare! Rival communications company squeezing you out in a particular region? Not any longer – not once their sat takes an unscheduled trip to the Lagrange point!
