Ooops! Shows you how "clumsy" humans are. Really now, how difficult
would a Junk Retreival Robot be? A universal thruster group or two
for redundancy, a tank of hydrazine, a hand to grab things, a radar
to locate the junk, and a directional finder to find your way back
to the station. You could make it tele-operated, but I don't think
something this simple would require that.
