AKIron: My wife had the audacity to ask me what the goal is with this Mars mission (as well as space exploration in general I believe she was thinking). I had to think on that one a bit. I don't think she really understands the "explorer spirit".
"Explorer spirit" is when a person or a group of people personally and voluntrarily donate their time, money and effort to some kind of exploration.
When a bunch of big-government bureaucrats use exploration to justify their salaries forcefully extracted from subjects, it may be avarice or arrogance but hardly and "explorer spirit".
Accusing NASA of "explorer spirit" is as false as accusing the government of being "fond of murder". They are not really in it because they like to kill people - it's only a pretext to gain more power and wealth.
Dowding: Space exploration is an expensive diversion that will only ever benefit multi-national resource exploitation corporations and the ultra-rich...
Right - and not because of the results achieved but because of wealth redistribution involved in the process.
GRUNHERZ: I disagree dowding, we must keep exploring and expanding. I imagine the same could have been said when Columbus was petioning funds for his voyage..
What was the result? The actual profitable for the society use of the newly-discovered continent did not start for a few centuries.
The only product that it was cost-efficient to bring from America with the level of technology that existed then was gold and silver - which ruined the Spanish economy by indicing inflation.
The discovery and exploitation of America a few hundred years later - when the european society and technology developed further - would have likely been less brutal, wastefull and more productive.
There is always an optimal return on limited amount of resources. If Mars exploration going on now was expected to bring fruits in 2050, starting it ten years from now would still have brough the same fruits by 2050 at much lower cost.
Dowding: exploration pale into insignificance beside the developments spawned from dedicated research through applied science.
Exactly - just take a look at the HHMI (Howard Hughes Medical Institute, $11 billion endowment as of 2002). Give a few hundred million a year to a few hundreds selected scientists and let them work on whatever they think interesting - with no paperwork required to justify grants, etc. Take Bell Labs, IBM, Xerox research centers and others.
The stories about "spin-offs" are mostly lies.
