Holy shit. So this satellite is rotating around the earth in orbit which means it must be moving pretty fast like most other satellites... except this one is leaking droplets of radioactive fluid, which at those speeds could be like radioactive bullets hitting a space shuttle. and with the thing obviously taking impact damage of some kind, what if it now falls to earth? I doubt it'll burst into a mushroom cloud, but it'd definitely cause fallout problems or extreme radioactive contamination wherever it were to hit.
