A bit tricky to get them back to the bench

I wonder if they used the same suppliers as our fellow forum members who sourced their rubidium clocks on eBay from China

Rohs comliance issue of Yorope? I mean the tin whiskers and all that self coused exotic stuff.
"Traditionally, lead was added to slow down whisker growth in tin-based solders."

I have read somewhere that anything safety qualified(especially Aerospace) is exempt from ROHS.

Hazardous substances aren't really a concern for something which goes up and stays up.

They do come down, but mostly as lots of very small well cooked pieces, and with 78% of the planet being water, there is little chance of them landing on land, and even less of them landing on habitable land. Of course most of the time they are controlled deorbits over the Pacific, but those that have sudden failures in either attitude control, power control or housekeeping tend to be those that do the dice roll of where they will impact.
