I'm trying to figure out whether the reporter is just badly math-unaware,
or did I miss something in Griffin's presentation. He said that NASA's budget will be unaffected (flat, plus inflation) to develop the new launcher. This story seems to have multiplied the total NASA budget by the number of years to flight to come up with a ginormously ridiculous figure guaranteed to deliver the project stillborn. http://www.cnn.com/2005/TECH/space/0...eut/index.html -- I was punching a text message into my | Reed Snellenberger phone yesterday and thought, "they need | GPG KeyID: 5A978843 to make a phone that you can just talk | rsnellenberger into."

It was so brief that it was gone before I started paying attention (and it was live TV, so I couldn't rewind it). I have no idea where that number came from either. |

Reed Snellenberger,
Try thinking inflation and thus hundreds of billions and, that's not even including the afterbirth of what each mission is going to further contribute towards pollution and, as such damage even more of our failing albedo by way of taking it directly into the nearest global warming space-toilet. At least robotics wouldn't impact our environment my 1% of that, though actually since robotics should function for years on end, that's actually achieving way better than 0.01% impact per mission. B1ackwater offers this moon related topic; NASA Back to Moon by 2018 - But WHY ? http://groups.google.com/group/sci.s...read/bfe561b9= 824b9f1a/ecfa8369f334ec56?hl=3Den#ecfa8369f334ec56 This is an extremely nice topic and as such it imposes a damn good set of questions, especially since we're nearly bankrupt. However, since "NASA formally unveils lunar exploration architecture", then perhaps we village idiots can seriously discuss those potentially lethal physical impacts, thermal issues, radioactive, reactive and atmospheric environment about our moon that really summarily sucks worse off than our resident warlord(GW Bush), especially by day unless you're one hell of a robot that at most couldn't cost us 1% that of any manned expedition, and not 0.1% if there's no return ticket to ride. It seems the status quo is entirely taboo/nondisclosure yet somehow that's perfectly fine and dandy for the likes of wizard "David Knisely", whereas otherwise life involving the regular laws of physics and hard-science that's the least bit outside the box is where pesky morals or so much as having a stitch of remorse sucks because; http://groups.google.com/group/sci.a...rm/thread/312= c0ee1964db812/85e2050d1b0c9a78?rnum=3D11&hl=3Den&q=3Dbrad+guth&_ done=3D%2Fg= roup%2Fsci.astro.amateur%2Fbrowse_frm%2Fthread%2F3 12c0ee1964db812%2F8ee6a5d= 795a6cc43%3Flnk%3Dst%26q%3Dbrad+guth%26rnum%3D7%26 hl%3Den%26#doc_abc3dca90e= b703fc There are some posters out there who feel the need to formulate their own elaborate theories about the heavens and their fate. And otherwise lord/rusemaster David Knisely having contributed yet another very nicely worded mainstream status quo rant, which is exactly why such all-knowing folks as Knisely are not likely going to contribute an honest need-to-know squat upon this next related sub-topic as to the lunar atmosphere and subsequent environment. The temperature on moon surface is what I believe can become moderated to suit, at least on behalf of greatly improving the odds on behalf of robotics that can be robust and thus engineered so as to not care about their local thermal or radioactive background dosage environment nor of whatever's incoming that's producing all of that truly nasty secondary/recoil worth of hard-X-rays. However, with having such a crystal clear layer of Radon plus another extended layer of Argon should create quit a well insulated surface baking environment that's capable of getting a damn site hotter than the sort of hell reported by our cloak and dagger MI6/NSA~NASA Apollo spooks. In spite of all the brown-nosed minions of their mainstream status quo that thinks and/or keeps insisting at we village idiots should only think that we've already done that and been there, thus why all of their need-to-know and/or taboo/nondisclosure that sucks and blows at the same time, which only seems rather out of proper form, especially when it appears that building/terraforming an artificial lunar atmosphere for robotics has been doable without our ever risking so much as one TBI white hair upon another astronaut: Not that I'm insisting this as the one and only alternative, however for further sportmanship reasons I'm thinking that the likes of Radon gas should become liquid at night and, otherwise expand out to perhaps an atmospheric depth of a km by day. Topped off by mostly argon that might reach as far as 50 km by day and something less than 10 km by nighttime/earthshine. According to Mike Williams; "The strength of the surface gravity (1.623 m/s/s) isn't the critical factor. What's more significant is the escape velocity (Moon 2.38km/s, Titan 2.65km/s)." "The heavier gas sticks around but the useful gas escapes. The various types of molecules settle down to having the same average kinetic energy, but that means that the lighter molecules move faster than the heavier ones. They move just as fast, in fact, as if the heavier molecules were not present." "There's a piece of JavaScript on this page http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/kintem.html#c4 that will calculate the average molecular speed given the molecular mass and temperature. N2 molecules (m=3D28) on Titan (T=3D-197C) average 260m/s which is about a tenth of the escape velocity. CO2 molecules (m=3D28) on the Moon (daytime T=3D107C) average 464m/s which is about a fifth of the escape velocity. That might sound OK, but not all molecules travel at the average velocity, some travel faster and leak away. The Earth isn't able to hold on to hydrogen molecules, and they average about a fifth of Earth's escape velocity." "Radon atoms would travel at an average of 206m/s on the Moon, which suggests that you could build an atmosphere of pure Radon." Density of dry ice: anywhere from 1.2 to 1.6 kg/dm=B3 depends upon compactness (avg 1.5 g/cm3) Frozen solid form at -78.5=B0 C Sublimes at anything much hoter than -78=B0C In a snowball form of compactness upon the moon it may represent less than 1 g/cm3. Radon, Rn atomic number: 86 Atomic mass: [222] gmol-1(no stable nuclide) Isotope: 222Rn (222.017570) Specific gravity of the liquid state is 4.4 g/cm3 at -62=B0C, and SG of the solid state becomes 4 g/cm3, thus 4 tonnes/m3 if frozen solid and especially frozen solid if that Rn were sequestered by the likes of frozen CO2 at 1.5 g/mm3. A cubic meter of each substance, that which Earth needs to get rid of anyway, represents a composite sphere of 5.5~5.9 tonnes, and that's not actually all that large of diameter of what can be easily directed at impacting (not orbiting) the moon. From the zero-G vantage point of such being accelerated from the nullification zone of roughly 60,000 km away from the moon gives an hour, in that there's an unobstructed path of least resistance that'll also benefit from the 1.623 m/s/s worth of gravity, whereas this should not require all that much added thrust energy for getting the final velocity up to good speed of final impact becoming worth at least 30 km/s (9 fold better KE bang/kg than DEEP IMPACT), although what's stopping us from achieving 60+km/s?. Our moon is already fairly radioactive by several fold greater than Earth, thus another clue that our moon is actually that of an icy proto-moon as having arrived instead of being ejected out of Earth, that plus the much having lesser density makes a whole lot more sense than any spendy computer model that's keeping the likes of a Pope and other terrestrial or but religions as happy campers. Of course, my lunar terraforming notions of artificially bombing the holy crap out of our moon with the likes of large blocks or spheres of dry-ice having frozen Rn within, besides creating whatever horrific meteor like impacts worth of vaporising lunar basalt into capably releasing a ratio of 1e6:1 worth of O2, the very nature of the delivered CO2 might subsequently revert to just good old elements of co/o2 or perhaps react into just C and O2, whereas the Radon element should have vanished within a few days unless we'd replaced and/or supplemented that lunar bombing of frozen Rn with the likes of including Ra226 which might even react quite nicely with the already available He3 into making a nifty long-term supply of creating Rn. After the Ra226 is sufficiently depleted, say in 6400 years it should be at 1/16th of it's initial potency, and by then having established a good amount of terraformed atmosphere as becoming the case since the amount of continual Radon-222 would have extensively moderated the hot/cold of the lunar day/night differential to something quite manageable for the likes of holding onto O2, whereas by then there shouldn't be hardly any significant local radioactive threat for naked humans that could be safely accommodated for 60 earthshine days upon the surface of our moon, that which a reasonably engineered moonsuit couldn't manage, or at least sufficient as for accommodating the likes of whomever we don't want living here on Earth (I have a growing list of whom those folks should be, roughly the bulk of the upper 0.1% of humanity that have been pillaging and raping mother Earth while continually snookering the lower 99.9% of humanity, and I do believe there should be plenty of available space on and/or within the moon for accommodating each and every one of those 15e6 folks in spite of all the deployed Ra226 that upon average shouldn't have modified the already background radioactive terrain by more than 10%). According to the above "Molecular Speed Calculation" of Argon-40, even if the elevated average altitude represented at worst 100=B0C (373K) would give Argon the maximum RMS velocity of 482.4 m/s which obviously should stick around. Even that of O2-32 only jumps to an RMS velocity of 539 m/s which should also stay put at least up until a truly nasty solar wind of 1200~2400 km/s excavates such lighter mass elements away. So, you tell me why artificially bombing our moon, and especially with the sorts of nasty stuff that Earth is getting more and more desperate to get rid of isn't such a good idea. So stick to just the cold hard facts and do not engage these fools. As time goes on, they should then fade and prove that knowledge rules! - D. Knisely Obviously this nifty rant closing was speaking on behalf of warning us about himself, as for our not bothering to engage such mainstream rusemasters because, doing so will only bring us MOS LLPOF infomercials and thus wasting human talents, resources of expertise and energy as well as sustaining collateral damage and continued carnage of the innocent. BTW; just because certain folks fade is more than likely because they're too smart to waste valuable time and resources upon the lost cause of humanity that's ruled by and thereby performing as brown-nosed minions to the upper most 0.1%, of which the likes of lord D. Knisely is apparently even somewhat above that. ~ Life upon Venus, a township w/Bridge & ET/UFO Park-n-Ride Tarmac: http://guthvenus.tripod.com/gv-town.htm The Russian/China LSE-CM/ISS (Lunar Space Elevator) http://guthvenus.tripod.com/lunar-space-elevator.htm Venus ETs, plus the updated sub-topics; Brad Guth / GASA-IEIS http://guthvenus.tripod.com/gv-topics.htm War is war, thus "in war there are no rules" - In fact, war has been the very reason of having to deal with the likes of others that haven't been playing by whatever rules, such as GW Bush. |

Reed Snellenberger,
Perhaps we should try thinking "inflation" and thus in honest terms of hundreds of billions and, that's not even including the afterbirth of what each mission is going to further contribute towards pollution and, as such damage even more of our failing albedo by way of taking it directly into the nearest global warming space-toilet. At least robotics wouldn't impact our environment by 1% of that amount, though actually since robotics should function for years on end, that's actually achieving way better than 0.01% impact per mission. Since our "NASA formally unveils lunar exploration architecture", then perhaps we village idiots can seriously discuss a few of those potentially lethal physical impacts, thermal extremes, radioactive and otherwise reactive facets and further about the atmospheric environment of our moon that really sucks, especially by day unless you're one hell of a robot and thus having no such DNA/RNA to fry or TBI to death. It seems as though, by way of my going "usenet postal" along with my trusty lose cannon has managed in spite of all of your defensive flak, whereas I've managed to hit a few more of those tender mainstream private parts, at least pricking a few of those status quo nerve-endings. Thus is apparently why others are not even pitching another one of their usual all-knowing and wag-the-dog efforts of damage-control or any other fits over what terraforming our moon has to offer, much less any notions of our sticking with almost if not entirely as to whatever robotics has to offer in the way of achieving the utmost bang for the almighty buck, while otherwise polluting mother Earth the very least per deployed kg. Imagine that, apparently I'm sufficiently right again and they're not. Nuking our moon via a sub-frozen CO2 dirty-bombs worth of hosting Ra-226/Rn-222 isn't quite the same thing as commonly thought of here upon Earth. Radium-226 which goes on and on with the process of creating Rn-222 gas is exactly what could become easily delivered to our moon using conventional SBRs as our Earth--moon torpedoes. Otherwise frozen Rn-222 sequestered within frozen CO2 may have to accomplish the task if folks can't take a hint as to what's otherwise possible. B1ackwater offers this moon related topic; NASA Back to Moon by 2018 - But WHY ? http://groups.google.com/group/sci.s...read/bfe561b9= 824b9f1a/ecfa8369f334ec56?hl=3Den#ecfa8369f334ec56 This is an extremely nice topic and as such it imposes a damn good set of rational questions and alternatives, especially important since we're nearly bankrupt.
