Hey, if an original Saturn V rocket kit goes on EBay for $450, just think how much this stuff is gonna sell for when we finally colonize Mars? And if humans never get there but some intelligence either develops there or visits there, these will be valuable artifacts.
I mean, look here

3 pieces of fossilized dinosaur poop for under $90 with shipping!
and if nobody ever gets to Mars, both practically and existentially what difference does it make? In 4.5 billion years (in the absence of divine intervention) the inner planets are going to be toast (or in the case of Mercury, Toastier!) anyway
