If space science isn't about science but say making footprints, it should not be claimed to be science, and it budgeting should come out of PR budget, not science or engineering budgets. Well, I'll answer that: it became about science towards the end of the Apollo program, when NASA realized that this huge organization it had built to put a man on the Moon and return him safely to Earth needed a new purpose. Science was chosen as that purpose (and indeed, this was the outward reason given for the Apollo missions -- mostly lunar geology). This was a bad choice in retrospect, though perhaps it was the only choice available. But nothing has come of space science so far that can justify the huge expenditures involved. Come out of it? If you want something to come out of it other than science data and even more science, then you should call it something else, and it should be getting its money from DARPA, DOE and similar. Oh, and it would probably getting more money at that. Now, space *development* -- that's another story. That's worth much more than what we're putting into it, because it addresses real-world needs in the near term (such as energy production, protection from asteroids/comets, etc.). Except the US has no such thing as a space development program, so teh point is moot. The public intuitively knows this -- when people are out there developing ways to live and work in space, they're interested, but as soon as it devolves into taking pretty pictures, we get a giant collective yawn and change to the sports channel. Unfortunately, we still have this myth rolling around that space is supposed to be about science. Engineering is certainly required for space development, and a small bit of science here and there is needed to support that engineering. But science is not the *reason* for space development. Attempting to make it so just undermines the whole enterprise. Again - if you want space engineering or space engineering research, call it that and blame DARPA, DOE, the mining and so on depertments for being damn stupid and not having a space related arm that is organising missions. Indeed, to put the cart properly behind the horse: once space development is further along, then we can build much bigger and better instruments to answer those cosmology and astronomy questions, much cheaper than we could today. So write to your reps in US goverment structures and ask when there will be space development parts in various deperatments and agencies that actually deal with development but have been lazing around so far and not doing anything about space related matters?

What use is manned space explorartion as things stand now and considering that teh same administration hasn't provided even one reason or goal for said manned explorartion? The goal is to start a permanent manned presence on the Moon and to set foot on Mars (and presumably return the crew safely to Earth). That is a clearly defined goal. Men have not set foot on any planetoid besides the earth for more than 30 years. The Bush administration is saying that it's time to start manned exploration again. IMHO, going round and round in LEO isn't exploring much. What does man setting foot there give us over a robot doing so ? This is the same argument the unmanned science community always uses. The answer is clear, if one has read the history of Apollo. What's not clear is whether or not the added cost is worth it. Certainly the added cost isn't worth it in terms of science, but there are other motivations for exploration besides pure science. Why do people climb Mt. Everest year after year? It's been done before. You can read other's journals, look at other's pictures, and etc. Why do we have people at the South Pole? Why not make all of that an unmanned operation? The fact is that space science and manned space exploration are goals that aren't very compatible. Bush is setting a clear direction by saying that manned space exploration comes first, otherwise, we won't move beyond "exploring" LEO. I hate to say it, but I tend to agree. Unmanned probes are useful, but what's the point if we're going to stay on the same rock forever? Why learn about Mars if we're never going to actually set foot on the surface? Where's the excitement in exploration by proxy (robot)? Jeff -- Remove "no" and "spam" from email address to reply. If it says "This is not spam!", it's surely a lie. |

Well, the administration hasn't given us anything yet. They've only leaked rumors that they're going to be talking about it next week. Perhaps some reasons will be given then, for those listeners who don't find the reasons for manned space development (let's not say "exploration" since that is rather pointless) to be self-evident. What does man setting foot there give us over a robot doing so ? Why, it gives us men (and women) there, of course. And that is the whole point.

And in fact, you'll notice that I didn't say anything about "space science" -- I said "space." and it budgeting should come out of PR budget, not science or engineering budgets. No, it has nothing to do with PR, though everything to do with engineering. NASA has its own budget, as you know, so it's not coming out of any "science budget" either. What I wonder is, why has so much science been taken out of the NASA budget, which would be much better spent on engineering and development? It would be good to have this corrected. Let the space scientists get their funding from NSF, like other scientists, and fly their experiments on whatever craft they can afford to buy or rent. (If that means "none" then clearly the state of the art needs to advance a bit before those experiments are practical.) But nothing has come of space science so far that can justify the huge expenditures involved. Come out of it? If you want something to come out of it other than science data and even more science, then you should call it something else, and it should be getting its money from DARPA, DOE and similar. You're using "it" to refer to two different things here. Let's review: I'm claiming that nothing has come out of space science that justifies the expense. What has come out of it? Why, science data and more science, just as you say. And I'm saying, that doesn't justify its expense, therefore we shouldn't be doing it (until it becomes cheaper). No, I don't expect anything else to come out of space science. I'm saying, the space science we've been paying for hasn't been worth it. Now, I think you then switched "it" above to mean space development in general, and you say that I shouldn't call that science (with which I agree), and that it should get its money from DARPA, DOE, etc. But NASA already has its own budge. The "S" in NASA doesn't stand for "science." I see no need (nor precedent) for one national agency to be getting money from another. Rather, we need to redefine what it is NASA's supposed to be doing with the money we give it. You seem to think it should be doing science, but I see no justification for that. Now, space *development* -- that's another story. That's worth much more than what we're putting into it, because it addresses real-world needs in the near term (such as energy production, protection from asteroids/comets, etc.). Except the US has no such thing as a space development program, so the point is moot. We have NASA, which was clearly a space development program in the beginning, and a very successful one at that. After Apollo/Skylab, things went rather downhill. ISS could have been a useful bit of space infrastructure, but we're all familiar with the problems it's had. Same for the shuttle, for that matter. But all the while, there have been some who have believed that it was all about the science. I don't think that was ever the case in truth, and it'll be good to have that clarified so that we can focus more openly on what's important. Again - if you want space engineering or space engineering research, call it that and blame DARPA, DOE, the mining and so on depertments for being damn stupid and not having a space related arm that is organising missions. You're still not quite getting it. I don't want space engineering research, I want space development. And we already have an organization for that -- NASA. If you want space science, why don't you have NSF fund it, or even propose some new National Space Science Administration (NSSA?) which can have its own budget? Let NASA focus on opening the frontier, and NSSA (or NSF or whatever) can benefit from this right along with everyone else. But first things first. Why should the space scientists get to go before, say, the movie studios? So write to your reps in US goverment structures and ask when there will be space development parts in various deperatments and agencies that actually deal with development but have been lazing around so far and not doing anything about space related matters? No, I write to my reps and ask them when NASA is going to quit allowing space science to distract it from its more important infrastructure development activities, and really get something useful accomplished, like a permanent lunar base. And maybe the answer is: "Next Wednesday." ,------------------------------------------------------------------. | Joseph J.

That's worth much more than what we're putting into it, because it addresses real-world needs in the near term (such as energy production, protection from asteroids/comets, etc.). I think one axis is development vs science and the other is manned vs unmanned. They might not be rigidly related. Most space development to this day has been unmanned, and that has also brought the most direct useful stuff to people's lives in the form of satellite services. (Weather forecasting, data relay, earth observation, gps) Then there are those more scientific matters that are also pretty directly important, like space weather, planetary atmospherical models etc... Of the manned missions on the other hand, ISS and the moon missions are almost the opposite. One is a continued mission which is supposed to exist almost purely for scientifical purposes and use international co-operation, while the other was more of a national prestige event, although it gave also lots of scientific knowledge. A few more moonflights might have given more, but what I understand, they were cancelled because they were dangerous and expensive. Anyway, because of the very fragile nature of man, manned missions in space tend to be heavy on the technology and engineering side, which these two examples were/are too, so they've done lots of infrastructure development as a side product (and thus cost a huge amount). But i don't think either has given that much direct benefit. Someone said that after a "flag and footprints"-type mission we're further from real space development than what we started from. Apollo was in many ways a "false start", a mega-project that got us a few people who went to the moon, but what after that? Ordinary people are still very far from going into space. Not to talk about any space colonies, we can't get a closed system to work even on earth. So, if a few guys go to Mars, what after that? What does it change? At least it's inspirational and bold, but I wouldn't talk about much direct practical advances to humanity. Maybe something useful is invented as a side-product, although that invention might have been done if the same money had been used with no relation to space at all. It's reasonable and honest to say that people get motivated and happier because of the spirit of a Mars mission, and not trying to find some concrete advances, which are side-effects anyway.. The public intuitively knows this -- when people are out there developing ways to live and work in space, they're interested, but as soon as it devolves into taking pretty pictures, we get a giant collective yawn and change to the sports channel. On the other hand, Beagle 2 and Spirit have raised more headlines and interest here than ISS. Unfortunately, we still have this myth rolling around that space is supposed to be about science. Engineering is certainly required for space development, and a small bit of science here and there is needed to support that engineering. But science is not the *reason* for space development. Attempting to make it so just undermines the whole enterprise. I think space is about science, direct use and inspiration. Manned space tends to be heavy on the latter, unmanned Mars missions maybe 50/50 former and latter and GPS or weather satellites very much the middle one. Indeed, to put the cart properly behind the horse: once space development is further along, then we can build much bigger and better instruments to answer those cosmology and astronomy questions, much cheaper than we could today. Cheers, - Joe Maybe once we get space elevators... I don't see manned Mars missions doing that (giving bigger and better instruments), but maybe that is to be pointed out. Big rockets, yes, but that's just a fraction of the manned Mars expenditure. I believe unmanned vs manned space is now in practical ways in a pretty good balance. A "permanent" space station in LEO for people and then deep-space exploration and science by robots. The space shuttle just needs replacing/retiring so it doesn't eat so much money. In a more spiritual way of course there might be a place for a more glorious manned mission. I just personally believe that the cost is too high, axing all the unmanned stuff. An alternative would be a really glorious but unmanned exploration mission, or a huge amount of FBC-missions, just group it under one name and image so that it's easy for people to understand. -- Valtteri |

I like your attitude, Joe, (pure science is not enough payoff for many taxpayers,) but that statement simply isn't true. We could well spend a decade or more sending robots ahead to prepare and test safe habitats and return vehicles, etc. |

Bush to announce new missions to moon
Doing the moon via "High Standards and Accountability"?
Well folks, what can we have to say about our leadership planning on returning us to the moon. All that I can say is, there's always a first time for everything, and/or how about "better late than never", as opposed to implementing our resident warlord's "so what's the difference" policy. Einstein remarked; "Great spirits have always met violent opposition from mediocre minds". Thereby, in order to please those "mediocre minds", how about we apply a little of Yull Brown's well documented and truthful physics technology, along with a few modern electrolytic zirconium membranes, just to see if we can't manage to create and/or extract pure h2o2 without getting ourselves blown to bits. Unlike the dubious Mars fiasco, at least the moon offers us many things, such as the most bang for the buck, and I'm not even referring to the he3 sort of bang, as that's an extra bonus for the ones actually capable of creating the one and only LSE-CM/ISS, which doesn't much look like our NASA is even in the running. Don't get yourself into another twit over my apparent disregard to those Mars missions, as I'll admire those hard scientific numbers that supposedly are going to be eventually acquired, even though so far there's been only more of the same, as in spendy photos of those meteorites and their shards strewn about a very frozen and irradiated to death Mars. Wait until we actually get something onto the lunar surface, and see first hand those even greater numbers of meteorites and shards strewn about the surface, along with a continual influx of micro-meteorites contributing at a rate of perhaps 1 per m2/day. Of course, the micro-meteorite (1 mm) influx would take 1e6 days worth (2,740 years) in order to fully paint a m2 with one such micro-meteorite layer, although as for to be standing within that m2 in a synthetic moon suit isn't going to cut it, as just the shards from each and every such nearby impact (we're talking 5+km/s, possibly 10+km/s worth of unobstructed impacts, along with a fewof those exceeding 30+km/s) is going to represent sufficiently nasty business, making whatever surface radiation issues rather insignificant. What seems somewhat more interesting, and of a whole lot more valuable to humanity, especially if man is going back to the moon, much less trekking off towards Mars or Venus, since even the likes of Yull Brown's efforts have essentially confirmed that "energy in = energy out" (that which created his 2h2o2), if we continued along the lines of what this original process created as Brown's Gas, how hard could it possibly be for safely obtaining just plain old h2o2? Though there's not all that much raw material to work with on the moon or even Mars for creating the likes of 2h2o2 or h2o2, there is however way more than enough to go around here on Earth as well as Venus, in fact especially Venus. For anything lunar, most all of such mission energy requirements will need to be imported, especially for extended expeditions and of surviving those adventures via any LM-1 bus. Again "energy in = energy out". Although massive solar arrays might be sufficient for accommodating base camp, there's no way anything mobile is going to be worth much if limited to whaever PV can contribute, especially if we're talking about a 25+ tonne LM-1 buss. If in fact "energy in = energy out" (can't hardly argue with that), thereby the process of creating, separating and/or improving upon the purity of h2o2 should be worth the effort. After all, the h2o2 (hydrogen peroxide) by itself is good for go, along with a small amount of c12h26 (kerosene) should be just the ticket for powering up the lunar LM-1 exploration bus IRRC engine, or of powering the likes of a shuttle/airship explorer that could effectively apply extremely efficient aerodynamics in order to navigate itself through the crystal clear CO2 ocean of Venus, and even robotically land on an existing tarmac. Remembering that the Venus retrograde trade winds are those rotating on your behalf, by merely taking advantage of those currents at various altitude can sustain a craft in nearly the same relationship to the sun, thus matching rotation for somewhat nighttime stationkeeping and/or migrating in relationship to the planet, while staying within their season of nighttime. Flying an airship/shuttle craft through the Venus atmosphere is almost like operating a submarine here on Earth, in places at nearly 1/12th the density of what water is, where the task of flying below those clouds and through the mostly CO2 crystal clear ocean of Venus is technically a done deal, certainly within the existing technology of what we now have to work with. Doing such within the Venus season of nighttime that isn't nearly as dark and gloomy as reported (at least not to any 0.01 lux UV camera), nor even nearly as hot and nasty unless you're planning on flying through and perhaps landing in their version of death valley, though why do that when there's lots to see and do that's residing 5+km above most of the hot and nasty stuff, and of a rather major territory that's 10+km and having nearby 17+km mountains. In either lunar or the Venus environments, the energy derived by the IRRC engine(s) would offer an efficient on-demand energy extraction solution that's relatively clean burning, while obtaining a good deal of energy density, a key element in doing business in such environments. This page is partly about the applications of such energy for a good cause, and/or as a result of achieving contact with others we need to be aware of: http://guthvenus.tripod.com/gv-interplanetary.htm Whereas these following links offer a bit more on the LM-1 application: http://guthvenus.tripod.com/gv-lm-1.htm http://guthvenus.tripod.com/gv-irrce.htm http://guthvenus.tripod.com/gv-h2o2-irrce.htm This ongoing report is having mostly to do with the reasons why we need to apply such good mechanical energy solutions for accessing lunar he3, preferably before others do: http://guthvenus.tripod.com/gv-lse-he3.htm This unfortunate page is mostly about what went so terribly wrong: http://guthvenus.tripod.com/moon-04.htm The final chapter on what we're going to have to do about our resident warlord isn't finished, and may never get that far if push comes down to shove. Though this would be a perfectly good and justified place for implementing his "high standards and accountability" that supposedly applied to our educational system, by fessing up to the truth, then implementing his "so what's the difference" policy once the world learns of how snookered they've all been. At least then we could get ourselves down to business without having to spend yet another hundred billion on sustaining the ruse/sting of the century. |
