Don't forget that manned flights provide some data NOT available from unmanned flights: How Humans can live/work in Space. This is important, since EVENTUALLY (hopefully before I'm too old...) There will be a need for a good amount of human labour in space (cheap & adaptable, not perfect but it's been pretty economical, and it'de be cheaper to have a person instead of a bunch of specialized gadgets) >We might even go so far as to say that a certain manned program almost >eliminated the US as a spacefaring nation. I wouldn't go that far, especially since even IF the Challenger disaster caused public opinion to go against manned space filght (In actuallity most of the people I talked too felt that NASA was taking too long to restart the shuttle program ) to the degree that the shuttle was discontinued. There would STILL be some sort of space program (I doubt that the Military would ask the soviets to put up U.S. spy satellites :-), not to mention that people like haveing the benifits of satellites (ie Trans-Atlantic Communications. Weather Fortcasting etc. TV, what would the news be like without any satellite photos. (The weather just wouldn't be as real for me ;-)
