That is a fair point. There are still examples of multi-year expeditions without any stops for resupply, such as antarctic expeditions of the early 1900’s, but they are a lot fewer; and many of those didn’t turn out too great.
I suppose early antartic expeditions would be a decent comparison point, an exceedingly dangerous and long journey when people already know they almost certainly won’t find anything ‘nice’ there. I suppose we know more about Mars now than they did in the antarctic expeditions knew in advance, but I think they had the general idea of what they could possibly find as being grim enough to be doubtful of it being worth it.
Ok, maybe I should have said single trips. Multi year expeditions involved many stops, a trip to Mars would be non stop.
