This book I am currently reading points out how environments can collapse, and take with them the society living off them. Collapse can come from climate change, man-made environment destruction, or both. Most climate changes he states come directly from solar activity(especially destructive for the first scandinavian settlement in Groenland) - something that we don't control - even on a terraformed planet.
My understanding of Josh's message is that controlled biospheres are less vulnerable to natural or man-made environmental destructions. I'm not sure of it, but it is definitively a point to take in account. Biomes we make a living from are definitively not forever, and the fate of medieval Groenland or Easter Island are a definite warning. The slower the environment is to rebuild itself is, the easier it is for us to destroy it forever - and to die.
Whose member of Appolo 11 did not land on the moon?

Well, my remark is more general. For this specific case, the cost would have stopped any action. I said about the Shutlle because it"s the only device ever built that could do that. And the price you state underlines the overkill of the Shuttle for that purpose.
What we lack is a way to make maintenance in LEO, at least low-level maintenance. Some kind of tugs(even unmanned) that would refuel sats & put back some screws would be very valuable in many ways. It would reduce the cost of operating sats, improve the economic interest of space in general, and the tech research in space. More related to this forum, it could help the assembly of a "beyond" spaceship in LEO - if this option was choosen.
Phobos Grunt is not far, maybe a few hundred of kilometers. Its damage seems not big, maybe just an antenna to tighten a little bit. Yet, we don't have anything to repair it, or whatever else. being unable to repair it once stuck on Phobos, well, that's beyond our reach for now. But just here, in LEO? We must be missing something.
And there is no more space shuttle to go there & repair the thing on orbit. I didn't like them, but I already miss them.
Hi all. Was known as el_slapper at the first forum, but suscribed after 2008, so seems I disappeared. Therefore I reappeared under a new name - that's not a big problem, I think.
