I don't like that cliche. It is at best inaccurate: the Apollo program did have a price tag. It was $110-$170 billion, depending on what all you include in it and when you consider the start. What the Apollo program and a Mars trip don't have is a clearly identifiable value.DiracPool said:I don't think it's difficult to gauge this at all. If you're referring to manned spaceflight and a Mars expedition in particular. Forget about the science per se for a moment. You can't really put a price tag on the adventure and human heroism a manned mission to Mars would yield.
To me, while the national prestige of Apollo 11 was great, it faded fast with later missions and lacking a cold war and given that no other country has been to the moon, that factor is virtually nonexistent today, for Mars. So to me, that intangible value is pretty low.
