<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>>>I suggest we pull the plug on this turkey and start doing some useful work, both on earth and in space. >So we should cancel human space exploration?? 1. NASA's mission should be to work with industry to develop the enabling technology needed for _practical_ human spaceflight. When human spaceflight is safe and reasonable in cost, then private industry and government research agencies will be able to utilize it for exploration and many other missions, just as they utilize the technology NACA developed in aviation. 2. Spending over $100B to go to the moon with 60's technology doesn't contribute to any long term goal, and is nonsustainable. Anyone who thinks public interest would be enough to keep the money flowing doesn't remember Apollo 12. 3. VSE effectively kills ISS after $100B in investment. If we can't find something useful to do on ISS we will certainly not find anything useful to do on the moon.>>In any case, it certainly smells like a giant ****storm is brewing...4. Unfortunately NASA appears to be stifling dissent rather than engaging in honest debate. We already have two underutilized medium-lift ELVs, Atlas and Delta. Soon we will have three, with Falcon, We certainly do not need four. And we could man-rate any of the three without interfering with Shuttle, since they use different pads. Wouldn't it make more sense to get a new system working _before_ we shut down the old one? <br /> Posted by vulture4</DIV></p><p>With one exception I have no problem agreeing with your post. That is #3.</p><p>There are NO raw resources in LEO at the orbit of the ISS. There are raw space age metal, oxygen in plentiful supply, and a great possibility of even water at the polls of the moon. There is energy aplenty, in particular towards the polls where he sun shins uninterrupted all the time, with no atmosphere to block it. There is only 0.16 in g for gravity, and no atmosphere to speak of, so getting materials off of the moon is going to very simple, quick, and easy.</p><p>In fact, the incredible luck of having such a large and unusually material rich moon at only some 250,000 miles from the Earth, IS the true key to having a space faring civilization!</p><p>And there will be plenty of true space research for the ISS to fully justify its expense also.</p><p>What we are discussing here is not whether or not we should have a space faring civilization in space, that should be a given to any of us! But, exactly how are we to obtain such a civilization at a reasonable cost. Even more limiting to our discussion is the exact method that would be both safe and relatively inexpensive in going not only to the ISS, but also outward to the moon, and eventually Mars and beyond. And the Constellation and the Ares I apparently to a lot of us is NOT that method! </p><p>And even more importantly, it looks like it just may not be the inexpensive and safe method that the next administration is also looking for either!!!</p><p> </p>
