[quote="Jim B"]This is a rather simpleminded analysis of the situation. Sure, sending man to mars might might headlines, might be exciting TV, but we don't have an unlimited budget to do everything that might be possible. Given the choice between spending $50B (or whatever) developing a manned mission to Mars, we can spend less money and do much more science on a number of smaller, less attention-grabbing missions. That became the official policy of NASA during the 90s, perhaps even the late 80s. Let's make a (perhaps bad) software analogy. Mozilla has $50M or whatever in revenue each year. They could do something bold and dramatic, like drop what they're doing, putting all their money and resources into developing a clean-sheet competitor to linux -- think of the drama and the attention such an announcement would get! -- or, they could keep making incremental advances on the state of browser technology. While the second choice is boring in comparison, the cumulative effect of those smaller steps yields greater dividends. The very day Bush announced the manned mission to Mars, I thought the whole thing was a joke. Do you recognize how many valuable programs with a lot of sunk costs were scuttled because of this PR stunt? The Mars rovers have discovered much more than any manned mission would, at a tiny fraction of the cost.[/quote]
