Via Maps Mania, we are invited to revisit the Kessler Effect (previously here and here) and the pressing, existential problem of space junk. NASA scientist Donald J Kessler conjectured in 1978 a upper-limit for density of satellites in low-Earth orbit, a threshold beyond which (a level that according to some estimates is already passed) even a minor collision could cause a catastrophic chain-reaction, an ablation cascade that would render subsequent launches impossible and leave future exploration grounded and triangulate the implications, connecting the dots, by finding constellations in the debris field as it becomes more fraught and a challenge to break through, like the pictured Broken Compass (see below, see also). What asterisms can you see?
