Tonight on GeekNights, after being distracted by a bright light, we discuss our opinion on the current state of manned space exploration. In the news, HDCP is broken, and Captcha Ads are definitely on the horizon.

However, if there is something that can be cheaply exploited, private industry will send something up every day. It doesn't have to be a resource. There might be some great processing methods that rely of free fall, for instance. The problem is the cost to get things up is so high.
That problem goes back to the circus nature of the 60s space program. Anyone with any sense could see that it wasn't sustainable as it was being prosecuted. If you always have to pay the cost of getting something into orbit, you're going to have a difficult time getting anything accomplished, because you always have that tremendous cost to deal with first.
That's why they should have built a sustainable space station first. It would be much, much cheaper to send things out from a station in low earth orbit than to constantly require things to be pushed out of earth's gravity well. Also, if there were a large, sustainable station with space given over to private R&D, then those free fall processing methods might have actually been developed.
I'm not entirely sure that more investment in a government program is needed so much as economic pressure on private industry.
As far as the "cut exploration in favor of local pursuits (for now)" option, I've been hearing that since 1973. No joke. 1973 was the first time I heard that, and the people espousing it then were adding the "for now" clause then as well. "For now" should be over by now, don't you think?
The biggest issue with gravity is that it takes more fuel to go the first 100Km than the second 100Km. Its that whole r2 in the Fg = Gm1m2/r2.
The ISS is not what I'm talking about. We could have had a station by now that would make the ISS look like an outhouse if we had done this with a view towards a sustainable future instead of making it a political circus.
What business cases there are for going into space have a huge barrier to entry to for maybe some pay off, and woe to the company that tries and fails.
Do you really think you can get enough venture capital by pitching the idea of "We have this product that has to be produced under free fall and want the funds to develop a cheap vehicle system to get to LEO to develop this product to sell, oh and we're going to have to spend 5 to 10 years developing the tech just to get into LEO and at the same time develop the technology for the station to make the product and get it back to earth safely".
What out there is there that has to be or could be improved by producing it in free fall?
I know that some smelting processes would be quite interesting when performed in a vacuum. Not having to worry about atmospheric contaminants would be very beneficial.
I am hoping, my own bit of wishful thinking, for one of the companies going after the Space X-Prize will aim a little farther and work out how to nab a Nickel Iron asteroid and put it into LEO or land it someplace unpopulated (or someplace we really don't care about, maybe Antarctica) and show how much raw material is up there for those who are determined.
A moon base doesn't have a lot of practical application yet. Someday it will, and we should continue to plan and study for one, but actually making it happen seems an appalling waste of resources when you have an electrical infrastructure that's lucky to still be standing and trains that barely run.
American's are too worried about themselves and their taxes to spend the money to do it right. So I ask you, if we aren't going to do it right, why do it?
Impotent people would definitely be out, though.
Come to think of it, it would probably be much more efficient to only keep women and semen in space.
As far as processes that could be improved in free fall, you've thought of a very good one yourself. Now, before anyone blasts me for this, please remember that this is pure speculation - I submit that free fall may be an advantageous environment for process such as drug manufacture, biotech (the main reason we don't know whether these things would work better in LEO than here is that many economic processes simply have not been tried there), and others that haven't been worked out simply because that's not the way anyone is approaching the problem. The last age of exploration was driven by economic exploitation, not by bringing American rocks back to Europe, and if the Europeans had said, "Why go to America? We don't know what's there, so we can't think of a way to make money from what's there", nothing would have happened at all. Some R&D; has to be done with the view towards making money on some product or process.
Argument from ignorance is not going to get us anywhere. This is another line of thought that would have crippled the last age of exploration. Did the Europeans wait until everything was fixed up nice and tidy at home before trying to exploit other lands? Europe was a shithole. The very fact that it was a shithole produced some pressure towards outward expansion.
If getting everything nice and tidy here is your prerequisite for exploring space, then space will never be explored. Face it - with that attitude as the starting point, there will ALWAYS be something that seems more pressing here. If not infrastructure, then some shortage of something or other, if not that, then environmental problems, if not theat, then overpopulation, if not that, then the energy crisis, and on, and on, and on.
