That Korean missel was not a satelite. It was a blank test shot sent around the world. Aimed toward the US West coast. Engineered to fall short and fall into the ocean. Fitted with a dummy load similar to the mass of a suitable war head.
Iran sent theirs all the way into space. Not simple to let that one fall into the ocean. I wonder if anyone has tried to ping that satelite to see if it can communicate? Or, is it another dummy load mass that now orbits in space?
