Ok, this sounds funny and interesting, but manhole covers are made of cast iron, and as such are brittle. A nuclear explosion quite possibly would turn that cast iron disk into dust. It could have, perhaps, been made of cast ductile iron, but it would have then at least broken apart into chunks. The energy dissipation of destroying a large chunk of iron would have cancelled most of its potential velocity. Very likely, the reason it wasn’t seen in the second frame is because it was dust, not because it was in orbit.

Zypper is by far the best package manager available, providing atomic and reversible updates, and their open build service makes reproducible builds. Those two are by far the best things about openSUSE. It’s not without its faults, which is why I have switched away at times, but I always come back after using the crap available in other distros.
You could record it and set it as your voicemail message, and just tell your contacts that it’s legit.
