Critics of human space flight (which I usually identify as) generally feel that manned missions are a huge waste of money. The case is made that the amount of science you get per dollar spent on manned missions does not make them worthwhile, and that money should be spent on better science. However, with NASA's recent talk about manned missions to Mars, I started thinking about the Apollo missions, and even though I normally identify as a critic of manned spaceflight, I find it very difficult to make the argument that the Apollo missions were a waste of time/money. This is putting my stance on future manned spaceflight into doubt in my mind... What say ye? If current manned spaceflight is a waste of money, were the Apollo missions a waste of money as well?
