	<htmltext>I strongly disagree. What is the point of exploring the universe in great detail, if humanity is going to live and die on Earth? Just spend what is necessary in order to figure out external risks like asteroid impacts and save the rest for more advanced navel gazing technologies.<br> <br>

The whole point of human space flight is the assumption that we will be in space sooner or later. Given that it's not that hard to put people in space for a length of time indicates to me that we'll likely have more extensive human presence in a few decades, but that's just IMHO.<p><div class="quote"><p>There will always be a barrier between man and off-world external environments, he will always have to interact through that barrier, so it makes sense to perfect systems that will do this remotely. We are already working toward that goal on Terra, where we prefer to send machines to mine the earth, explore the depths of the sea, disrupt IEDs, and so forth. It is a natural progression to do this in the utterly hostile environment of space.</p></div><p>I agree with the first sentence. This is the primary reason we'll always have unmanned space exploration. No matter how good we get at using people in space, they can't be everywhere. Distance, if nothing else, will be a barrier between humanity and many of the things we wish to explore - even in the Solar System.<br> <br>

As to your second point, those are not significant demonstrations of remote operation of the kind done by NASA's unmanned program. Humans are still on location to maintain the machines and do other tasks. A Martian analogue would have people going to Mars, but spending most of their time in a central location (say fixing or managing stuff) while robots do the actual physical exploration and other grunt work.<br> <br>

Your comments also bring up one of the problems I have with NASA. What do you think of when you think of NASA's manned space program for the past 30 years? Most likely it is the Space Shuttle and the International Space Station. What do you think of when you consider NASA's unmanned space program? You probably think of the Voyager missions, Hubble Space Telescope, numerous very successful missions to Mars, Cassini and Galileo, etc. With manned space flight, you think of building and maintaining expensive infrastructure. With unmanned space flight, you think of space exploration though by expensive, unique, rock-star-style missions.<br> <br>

The bottom line for me is that manned space flight has little use; unmanned space flight has somewhat greater utility; but neither really are worth the money sunk into them. You can claim that manned missions are inefficient, but I see no evidence of that. What I do see is a vastly unambitious and unsustainable effort to explore space either manned or unmanned. First, to address the unambitious part. Manned space flight has for the past thirty years never gone past LEO. The high point is a $100 billion (or more) space construction project that might end up doing a little space science on the side. This is pathetic.<br> <br>

On the unmanned side, we have a cycle of space science that is so slow that scientists routinely die of old age before a probe is allotted to explore unanswered questions from previous missions. For example, the infamous Viking <a href="http://en.wikipedia.org/wiki/Viking\_biological\_experiments" title="wikipedia.org">labeled release experiments</a> [wikipedia.org] won't be duplicated for 35 years (or more) past the time of the original experiment.<br> <br>

Compare this to the Apollo program. In a span of eight years (1961-1968), the US sent 21 space probes to the Moon (I believe 8 of them failed, 6 in the first four years). NASA then sent seven successful manned missions to the Moon (plus Apollo 13 which was a mission failure but passed around the Moon briefly). One merely orbited (Apollo 8), but the other six landed on the Moon (Apollo 11,12,14,15,16,and 17). The last three had manned lunar rovers which traveled at least 25 km. And collectively the missions dropped off a bunch of instruments and returned 380 kg of samples. I think the whole project from inception to end was somewhere over eleven years. Even now, I don't think one can repeat via an unmanned program the scientific accomplishments of Apollo without spending a similar amount of money. And with the current attitude in the unmanned space program, I don't see a similar program of exploration unfolding. The somewhat lower budget doesn't excuse the lack of ambition.<br> <br>

The real problem with Apollo wasn't the ambition, the "flag and footprints" goals, or the expense, it was that nothing long term came of it (the previous flaws might have contributed to this final problem, but they do not explain it). When the money stopped flowing into the program, there was nothing left to support the infrastructure and activities that comprised Apollo. In other words, Apollo wasn't sustainable. The same thing is going on today with most NASA activities. When the Shuttle stops flying, we might have a Shuttle-derived vehicle, but NASA will still be one cancellation away from losing its space program. Similarly, for all the missions to exotic locations, NASA has yet to do anything to make those missions cheaper or more capable, aside from a modest amount of technology development.<br> <br>

My view is that currently, the only activities that are self-sustaining are commercial and military/reconnaissance satellites. These not only perform things that are inherently valuable, they often pay for themselves, as in the case of commercial activities. In fact, I consider commercial activities the best possible use of space because these activities are inherently self-funding. One needs not convince the US voter, year after year, to throw money in the hat. This is the great ill of NASA. It is simply not doing enough to enable commercial activities in space. I consider that the best possible use for NASA and far more important than these pointless arguments about manned versus unmanned space activities.</p></div>

	<htmltext>I guess the inability to design a user replaceable battery wouldn't be such a design failure on an unmanned mission to Mars.<br> <br>

More seriously, I don't completely buy the 'It wasn't designed for a 90 day mission' claim that keeps being thrown out there.  It certainly was NOT just about managing expectations.  The cost to build a device that will last 6 years in a harsh environment is going to be dramatically more expensive than one that is designed to last 90 days.  If they really did design the rovers to last 6 years, then they did a phenomenal job in securing funding for the first 90 days.</htmltext>

	<htmltext>The study of galaxies has implications for celestial navigation. Stars move around. Because we've studied galaxies, we now understand why they move and can predict movement of our Sun and any particularly bright stars we use for navigation. Also, if you're going to use the sky for navigating expensive things in space, you better know what all those fuzzy blobs and other doodads are.<br> <br>

The value might not be astounding great, but I have yet to hear of some scientific discovery which didn't have immediate application yet managed to have great value down the road. I believe it is a myth that science is something you do with no expectation of immediate payoff. Such an attitude just leads to sloth, corruption, and incompetence, such as has happened in the space programs of the world and fusion research.<br> <br>

Finally, it still bothers me that you thought plate tectonics didn't have immediate application. That borders on the absurd. One could be forgiven for assuming that the discovery of galaxies didn't do much for humanity, but plate tectonics is one of the biggest discoveries of the 20th Century with immediate application. It gave us the key insight into why Earth looks the way it does. Virtually anything that depends on the lay of the land, be it large scale construction, farming, mining, warding against the greatest of disasters like earthquakes and volcanoes, or exploration into the distant past of the Earth, is affected by this.<br> <br>

Millions and perhaps billions of peoples' lives depend on this insight. For a simple example, the earthquake that recently hit Haiti is similar to earthquakes that hit Kobe, Japan in 1995 and San Francisco/San Jose, California (Loma Prieta) in 1989. The Haiti quake, last I heard, is thought to have killed 70,000 or so people. But these similar quakes in similarly populated areas killed a tenth of that (virtually all deaths come from the Kobe quake and buildings that weren't up to any earthquake code). The reason is that these other cities had designed their buildings to withstand earthquakes (via regulation and engineering research).<br> <br>

The model of plate tectonics predicts both the movement of continental plates and the presence of earthquakes where plates meet. It explains "faults", places where huge land masses grind against one another. Most important in my example here, is that it explains the need for earthquake proofing buildings in certain regions. Just from two earthquakes which happened within a generation of the development of the theory (in the late 60's).</htmltext>
