Very nice. Why did this mission include a Voyager-style message while others don't (or do they?)?

Anyone besides earthlings who can read the message would come from outside our solar system, so why put the message on Europa instead of the many other possibilities? Why would the interstellar travelers head for Europa? If they master interstellar travel, they could find Earth.

They probably just needed some sort of counter-mass or some other similar element and figured they'd turn it into a PR thing. Similar to how New Horizons ended up carrying some remains of the person who discovered Pluto, or IIRC parts with names on Perseverance of people who worked on the rover.

I'm fairly certain NASA will dispose of Europa Clipper in order to prevent any chance of forward contamination, just like what was done with Cassini.
