Hidden Feature of Perseverance
For those of you who are fans of the Voyager plaque:

You might enjoy this article about the plate (on the rover) that is used to periodically calibrate the camera(s) that are used to take precision measurements on Mars:

It would appear to have just as much thought put into it, although without the pointers to trace it back to Earth (any sentient being that finds Percy, and can't find us on Earth should have their license revoked), as the Voyager plaque. With magnets to keep the red/iron dust off of it to maintain the color; wow, good thinking. Wouldn't work for plain old earth crud.
Missing of course is an alphabet to decode the language used on the plate; at least they could provide a pointer to google and some wifi.
Definitely not talked about, but a very interesting hidden feature of Perseverance.
