And absent the space race you can get into endless secondary what-ifs - would Trek: TOS have existed to propagate space tropes beyond SF geekdom into the general pop culture? <br /><br />But I suspect that some modest space program would have developed anyway, growing out of sounding rockets, the X-plane program, etc. And once established it would survive - as NASA has, on a larger scale - basically because the sheer coolness of space travel provides a base of public support.Rickhttps://www.blogger.com/profile/16932015378213238346noreply@blogger.comtag:blogger.com,1999:blog-3412583847145043520.post-51153412774128118142011-01-31T15:08:42.506-07:002011-01-31T15:08:42.506-07:00I don't mean to sound flip here. Well, I proba...I don't mean to sound flip here. Well, I probably do, but I shouldn't. You're certainly correct that this isn't a no-brainer. It seems to me, though, that for many years now, the default answer has been that we need to continue manned space research simply because we need to. Justifications beyond "We need to send people into near space so we can better send people into deep space" are rarely offered, and I don't think they get to the real question of what exactly we're doing up there. <br /><br />If we had never had a space program up until now, would we create one, absent a rocket duel with another world superpower?Seth Maskethttps://www.blogger.com/profile/17178036016555722068noreply@blogger.comtag:blogger.com,1999:blog-3412583847145043520.post-88079184217905692022011-01-31T12:10:09.687-07:002011-01-31T12:10:09.687-07:00At this point the purpose of human space missions ...At this point the purpose of human space missions is to learn how, and how well, humans live and work in space. The International Space Station is, effectively speaking, a training flight for prospective deep space human missions. Asking whether the ISS does 'science' is like asking whether the X-15 did 'science.' <br /><br />Whether human deep space missions are a worthwhile goal is a fair question. On the one hand, humans on the spot can explore and analyze far more effectively than robots with fixed capabilities, remote-controlled from 200 million km away. On the other hand, getting humans to the spot is (currently) horrendously expensive and pretty damn hazardous. I come down in favor, as you can figure if you follow my name link, but I don't think the answer is a no brainer either way.Rickhttps://www.blogger.com/profile/16932015378213238346noreply@blogger.comtag:blogger.com,1999:blog-3412583847145043520.post-56701518817575744812011-01-31T09:37:27.251-07:002011-01-31T09:37:27.251-07:00Then what is the purpose?Then what is the purpose?Seth Maskethttps://www.blogger.com/profile/17178036016555722068noreply@blogger.comtag:blogger.com,1999:blog-3412583847145043520.post-60136312448540576852011-01-31T08:32:06.221-07:002011-01-31T08:32:06.221-07:00But it is hardly as if the purpose of space missio...But it is hardly as if the purpose of space missions is to get from one place to another on Earth!Rickhttps://www.blogger.com/profile/16932015378213238346noreply@blogger.comtag:blogger.com,1999:blog-3412583847145043520.post-85286961564037305512011-01-29T08:00:50.430-07:002011-01-29T08:00:50.430-07:00If you measure it per mile flown, yeah, it's g...If you measure it per mile flown, yeah, it's great.
