I've yet to see any industrial product currently manufactured in zero-g. Sure, its possible, its just not worth the effort.

As for the secondary, yes, you may be able to get from orbit to ground in an hour, but you have to add to that the time it takes to first assemble, package, and get your cargo to orbit, then the time required to prep your spacecraft for the delivery, plus the wait for all the orbits to line up, plus the time required for weather delays, countdown interruptions, securing overflight permissions, safety concerns, landing site prep, and all the other administrative and technical overhead that goes into launching and recovering a spacecraft. And then, there are places on earth (like near the poles) where it is hard to get to from LEO, it would be necessary to have multiple orbiting platforms ready to get full planetary coverage.

Forget it Buck. There is absolutely no good reason to go to space except to do the science that can only be done there. And that can mostly be done by robots a lot cheaper. Yes, manned exploration and colonization is the ultimate goal, and I have no doubt we will someday find very good reasons to do that, but not now.

Yes, I read all the science fiction yarns about orbital earth resource monitoring labs, zero-g factories, observatories, medical facilities, military recon and early warning outposts, com relays and the only ones that have have actually materialized are being done by robots like Landsat, Hubble and GPS. The rest is all space groupie fantasies desperately clung to by overgrown adolescents who are waiting for an invite.

Remember, just because something can be done, doesn't mean it must be done. And it certainly doesn't mean it should be done.
