Since the Outer Space Treaty that covers space junk is a nation-to-nation treaty, that could be a pretty interesting way to assert some First Nation sovereignty if any SpaceX pieces are found on First Nation land...
I just cold-called the band offices of 2 First Nations that own reserve land right near where the space junk was found and offered to help make connections if anyone finds space junk on their land.
Time for audience participation: have any of you seen any news articles about the SpaceX pieces in Saskatchewan or North Carolina where SpaceX has publicly admitted that it's theirs? Or even responded to a journalist in any way at all? I think they still haven't publicly admitted it
(Although I saw a printout of the email from SpaceX to the farmer, so they have certainly admitted it to him)
