Mr. Nobody's Rocket

 Many years ago I worked as a part time admin assistant at the National Institutes of Health. I was working lab-adjacent (never actually went into the lab because, ya know, bio-control).

One day I discovered a mouse in my office. This mouse was clearly a lab mouse, of a strain used primarily for gene knockout research.

"Who lost a mouse?"

Not a single scientist on that floor was willing to admit to having lost a mouse. And we never did recapture Mr. Nobody's Mouse. It eventually disappeared. (Threats to bring in a cat were made).

Mr. Nobody's Mouse is probably still a story there. It's certainly one of mine.

Now we have Mr. Nobody's Rocket. Because the rocket that slammed into the moon?

Nobody wants to admit to having launched it.

It made a double crater too, which is really weird.

Maybe it's aliens?

More likely it's somebody's spy satellite launch gone very, very wrong.
