And exactly how many samples did *all* of the Mars rovers return to
earth? Zero.


Even if you want to compare returned lunar samples, Apollo 11 returned 68
times the amount of material returned from all 3 Soviet sample return
missions combined.

And from a larger area.


Unmanned rovers "doing science" is quite inferior to manned missions
returning *many* samples to *far* better equipped earth based labs for
detailed analyses.
