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

How much would a manned Mars mission cost?

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.

Selected during 2.5 hours of EVA time. And for much more money.

Using people as biorobots is hideously expensive since you need to keep
them breathing and drinking and eating and comfortable during years of
no science being done at all.
