OK, fine...
Space vs. undersea vs. medical vs. whatever funding aside....
So it's expensive and risky. Let privately funded groups do it. Give them huge tax credits or access to government sites/data/something. It'd still be cheaper than big Gov doing it alone. Not to mention the SPEED of development would be (first bad pun....) light-years ahead of a government project.
AND, so people die here and there. I seem to recall that people called "explorers" in the history books died quite a bit, or at least someone in the party did. Apollo 1 anyone? And to think that NASA kept at it. Nowadays such a disaster leads to years of inquisition and pink slips. How many humans have died in the development of modern aircraft? So just get over it, and let them put their lives on the line if they want to. To use the airline's model of statistics, more people have died in car accidents on the Earth in the last couple of days than have died in all the years of human payload rocketry, right? I'm sorry if that angle offends, but let's face it, like a previous poster said, there's a difference between investigation and exploration.
The only way we're going to get over all the years of "it's too expensive" "it's too dangerous!" "I might muss my hair!" is to have someone just go. My bet is private industry beating big Gov. to the punch. Followed by a neck in neck second by Russia and China. 5+ years later the US will at that point be ready to send their third automated lander to the moon (having been successful with 1.0 and 2.0, they dare not risk a human being on 3.0.) After all, they changed the paint scheme and the landing gear surfaces....
Oh, and to make a rant even longer..... Why in the H.E. double hockey sticks is NASA taking so friggin' long to get back to the moon? You've already gone before! So modernize a little here and there and just go already. 2012? 2020? WTF? Refine as you go. Just move the big erector set in the sky to orbit around the moon, or build another one. Stage supplies at ISS and the moon-ISS. We humans have THAT tech down already right? So stop wasting billions on robots to "test" the technology and just frickin' go! Business already knows this: Quantity leads to lower costs. Get the rest of the space-faring (bad pun two...) countries in on it, and spread the cost. The Russians have heavy lifters and long term cosmonaut experience. The US has the lunar experience. Rutan and co. have already proven sub-orbital flight can be "cheap", so help refine it. Etc. Etc.
Take the risk and just go. There are plenty of people out there, that are NOT rocket scientists but are mentally stable enough, that would sign up to go up regardless of risk. Going to orbit is old hat. I mean, no disrespect to the *nauts and all.
I can't believe I'm going to post this drivel... Too wordy, to disorganized, and not enough beer. Sorry. *faceplants into keyboard*
