Mysterious metallic Space Ball

This photo (provided by the National Forensic Science Institute) shows a giant metallic ball, 1.1 metre in diameter and weighing some 6 kilograms (13 pounds), that fell out of the sky on a remote grassland in Namibia. So far, they haven’t had much luck identifying it, so have called in NASA and ESA, hoping for some answers.  via popsci

Mystery solved: the metallic ball has now been identified as a hydrazine tank from an unmanned rocket, commonly used in satellite launches.
