Geoffrey A. Landis,
It seems that your "Science Journalism" sucks even bigger and better than a black hole. Even the notions of Russian and/or the Chinese robotically mining the moon may have always been a bit easier than we'd thought. However, before we common folk, the likes of "tj Frazir" and myself (in other words the apparent scum of the Earth according to whatever the mainstream status quo has to say) can fully appreciate "What's actually HOT and NASTY about Venus", whereas instead we may need to regress ourselves by a few decades in order to fully appreciate the hard-science that's recently become available as pertaining to what's actually all that HOT and NASTY about our Moon? The task of getting whatever safely and thus having to softly deploy upon the extremely dusty moon is doable as long as those forms of robotics are small enough so as to being least massive, so as to slowing the arrival of them suckers down to perhaps 10 m/s and, they are of a sufficient surface coverage configuration so as to not summarily sink out of sight. Besides the raw solar influx aspects of 1.4 kw/m2 scorching continuously upon most any given portion of the moon for nearly a month at a time, thus getting whatever's dark and nasty extremely hot and not to mention damn reactive as all get out. How about for the all around sporting heck of it all, lets say we jump off the mainstream status quo good ship LOLLIPOP that's been entirely owned and operated by our NASA/Apollo rusemasters, in order to discuss our going back to our moon for the very first time, so as to get an honest to God grasp upon whatever the lunar atmosphere is actually all about. Of course, I'm speaking robotically since it's usually so downright hot, reactive and physically nasty or otherwise just damn cold and nasty upon our moon, not to mention that robotics are certainly a whole lot cheaper than clumping moon-dirt and obviously so much safer as compared to human efforts and, since we're talking of accomplishing this as a one way robotic ticket to ride and there shouldn't hardly be any R&D required, as such robots are going to be damn fast at getting the job done, and without any need of their having banked bone marrow standing by. Seems rather gosh darn pathetically odd that there was never one usenet contribution or even a worthy sub-topic generated thought as to appreciating this perfectly nifty NYT published consideration; Moon's thin atmosphere extends farther than thought http://groups.google.com/group/sci.a...201e82b060a176 FROM THE NEW YORK TIMES: Moon's thin atmosphere extends farther than thought (c) 1995 Copyright Nando.net (c) 1995 N.Y. Times News Service Now researchers at Boston University, who two years ago determined that the rarefied gas bubble surrounding the Moon extended 5,000 miles high, say new studies show that the lunar atmosphere reaches out twice as far. The astronomers, Dr. Michael Mendillo and Dr. Jeffrey Baumgardner of the Center for Space Physics at Boston University, said that during the eclipse the Moon was totally in Earth's shadow, blocking the bright moonlight that obscures observations of gases in the lunar atmosphere. Under these conditions, the astronomers were able to detect the faint glow of sodium gas, which serves as a marker for other gases in the lunar atmosphere. "We were surprised to find that this glow extended to over nine times the radius of the Moon, to a height of about 14,000 kilometers, or 9,000 miles above the Moon's surface," Mendillo said. The researchers say their observations have enabled them to rule out some theories on the origin of the lunar atmosphere. They believe that the most likely explanation is the evaporation of atoms from the lunar surface when it is struck by light particles called photons coming from sunlight. Sodium and other elements escape the surface through erosion caused by the bombardment of photons. The astronomers earlier ruled out a suggestion that the lunar atmosphere was formed by the constant bombardment of the surface by micrometeorites. If the micrometeorite theory was true, they said, the atmosphere would be evenly distributed instead of being irregular in shape, as their measurements indicate. Another theory holds that solar wind -- charged particles streaming from the Sun -- kicks up surface atoms as it lashes the lunar surface. But the researchers said this theory now appeared to be eliminated because Earth's magnetic field traps solar wind and shields the lunar surface during the full-moon phase, when their observations show the tenuous lunar atmosphere fully extended above the surface. - If the regular lunar atmosphere extends out as far as having been reported, then obviously doing the math of what was at the time of Nov. 1993 as having been detectable at 8r (14,000 km) off the lunar deck as representing perhaps 100 atoms/cm3 worth of sodium, whereas that amount certainly represents quit a bit of what's compiled upon the deck (12.8e6/cm3 or 12.8e9/m3), especially since sodium is most certainly one of the lighter elements of available mass that's associated within the mostly basalt lunar surface that's having been continually giving berth to such sodium gas. Obviously from meteor impacts that contributed a great deal of further insult to injury were subsequently generating massive amounts of additional sodium atmosphere, thereby having co-generated other elements such as good old O2 of which the molecular speed of hot O2 simply wouldn't have been so easily excavated away by the typical hot and nasty gauntlet of solar winds (100~300 km/s). Upon being under siege my a nasty gauntlet of micro and not so micro meteorites might easily suggest having multiplied the atmospheric population of sodium by as great as a billion fold, making the near surface sodium density worth 6.4e15/m3 plus the other heavier elements as equally having been released becoming near worthy of creating 0.028 bar. This image and information as to Leonids impacting the Moon imposes further notions as to what the intensity of such impacts created with respect to the visible aspects of sodium. http://science.nasa.gov/headlines/y2000/ast26oct_1.htm Without a surface deployed probe taking various direct measurements, as such we can't possibly begin to imagine what that surface environment situation would have looked and felt like up close and personal. Of course I've tried several times to suggest we need this sort of raw data and, lo and behold each and every time the mainstream status quo of need-to-know and otherwise taboo/nondisclosure flak was insurmountable. Besides the O2 that most certainly had to have been made available, there's also Argon, Xenon, possibly a touch of CO2 plus other extremely heavy elements, including the likes of existing Rn-222(radon) that's around most of the time as having been naturally created by the available Ra-226(radium) and via secondary/recoil reactions as having been solar and cosmic contributed. Therefore, our moon is not nearly as devoid of an atmosphere as we'd thought. As for deploying the modern day micro probes of perhaps as little as one kg becomes quite doable, with somewhat larger deployments accomplished as each of these highly affordable efforts produces a better understanding of what other methods can be achieved within such a thin but otherwise available atmosphere that's actually fairly respectable considering the 1/6th gravity factor. 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=28) on Titan (T=-197C) average 260m/s which is about a tenth of the escape velocity. CO2 molecules (m=28) on the Moon (daytime T=107C) 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." Of course, for building and sustaining that sort of a radon atmosphere, as for that to happen the moon requires having a good amount of background cash of radioactive elements including Radium(Ra-226) as for generating the Rn-222 gas, although a good amount of raw solar influx and thus secondary/recoil reactions might otherwise accomplish this same task, that plus the matter of accepted fact that our moon has been identified as being considerably more radioactive than Earth shouldn't have gone to waste. Fortunately for us humans terraforming our moon into being livable (at least within seems doable), radium (Ra-226) half life is 1600 years and thus the radon as having been generated shouldn't be around forever. In fact, if our icy proto-moon wasn't so gosh darn newish, as such most of the radioactive raw elements simply would have faded away by now, that is for other than whatever's continually solar and cosmic contributed and supposedly responsible for creating the amounts of sequestered He3, of which someone eventually needs to go there and process for obtaining that nifty substance before Earth runs itself entirely out of fossil/geological based energy and we manage to turn our Earth into another Mars. ~ 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. |

[Sorry about the delay, but one or two may still be curious] Like Ceres was called "asteroid" when this word directly means "mini-planet". 'Asteroid' means 'star-like'; the term was coined in 1802, after the discovery of Ceres and after it was seen that the disc of Ceres couldn't be resolved. "planetoid", likewise, means 'planet-like', and I suspect the asteroids got labelled planetoids after spectroscopy started to show what they were made of. Can't find a decent coinage date for 'planetoid'; I don't have OED access. I finally got around to poking a friend who has access: 1803 Edin. Rev. I. 430 Why may we not coin such a phrase as Planetoid? 1803 HERSCHEL in Phil. Trans. XCIII. 339 It is not in the least material whether we call them asteroids, as I have proposed; or planetoids, as an eminent astronomer, in a letter to me, suggested. (Herschel is the first citation given for "asteroid", too, in 1802. Busy chap.) -- -Andrew Gray |

Geoffrey A. Landis,
Of "Science Journalism" I'm not. Of the truth and nothing but the truth (math, dyslexic and syntax errors to boot) I am. Without any regard to whatever observationology should have to offer (because it seems with most of the mainstream status quo of seeing whatever is not believing anyway, unless it's another WMD disguised as a big-ass fire-engine truck or that of a donkey hauling a cart with essentially a butt-load of pop-pop rockets); I'd like to ask from the ET perspective, as to why pick Venus when Mars is simply so much further away, mostly sub-frozen, hardly any atmosphere, thus easily pulverised and quite nicely TBI to death? This time I'm only thinking just a little further outside of my usual box; What say that it's been an ET game of HIDE and SEEK (of planetary pillaging and plundering right under our brown noses) all along. This topic may be somewhat like "crop-circles" on steroids, with the exception that I believe ETs are playing a for real finders keepers. However, since we're mostly snookered (many of us having been snookered to death), thus we're so dumb and dumber that we can't even find Osama bin Laden, nor do we realize what an absolute LLPOF SOB of a resident warlord(GW Bush) we have running us amuck, thereby what chance in hell (perhaps literally) would we have of uncovering even that of a somewhat massive ET operations as having transpired upon Venus? If you were an ET as having been sent on a expedition to a nearby solar system, as in somewhat out and about looking for a viable planet to pillage and plunder, such as looking for a viable orb as having rare minerals and possibly the likes of diamonds, especially if interested in obtaining atomic elements (thus you certainly wouldn't want an extremely old Mars like planet that's already past its atomic half-life and having a nearly dead core to boot), however if there was another somewhat geologically newish planet as per having an ample supply of ready-made green/renewable energy at your disposal might represent just the ticket, especially if having so much spare energy that you didn't have to deplete whatever your spaceship and/or spaceplane had of essential get-home energy (possibly He3/Deuterium fusion), that or perhaps just having a good inventory of Radium(Ra226)--Radon(Rn222) being of a fairly powerful ion thruster fuel, the same energy that got yourself and whatever motley crew into our solar system in the first place. What if those choices of pillagable planets became the threesome of Venus, Earth and Mars. If you had to pick; Which one would you most go for? Remember that you're already a good million or so years more advanced than us humans, thus seasoned space-traveling ETs, whereas if need be you could possibly get by on Titan, and since you're certainly not the least bit heathen nor nearly as snookered and thus least dumbfounded, whereas chances are that you and your crew actually know a little something extra about applied physics, and you'd think knowing the realistic limitations as to exactly how much cold or otherwise hot and downright nastiness you can manage to survive upon without your having to drag every last stitch of the entire expedition requirements along for the ride. In other words, it would be darn nice to getting situated upon a planet where the likes of having surplus green/renewable energy is essentially everywhere you'd care to settle in for the next 100,000 years. Remember that you'd want the least possible resistance from whatever locals. Remember that getting yourself to/from whatever orbit needs to be energy manageable. Remember that getting summarily pulverised out of nowhere isn't exactly part of your plan-A. Remember about background and influx of lethal radiation that'll need to remain as minimized. Remember that you would not want yourself or your montely crew getting infected with lethal microbes. Remember that even being space-traveling ETs, that you still have biological and certain other limitations. Remember that you'd like privacy, keeping as much as possible out of sight and thus out of neighboring minds. Especially important, as much as possible keeping your expedition of whatever operations out of sight and thus out of the nearby heathen minds of such absolute bigoted and arrogant fools that'll invent WMD just for justifying yet another perpetrated blood-sport of a war and, as otherwise for their pretentious ruse of global energy domination, by way of taking the energy resources of whatever belongs to others or, at least keeping such potentially affordable energy out of the hands of any competitive groups that might actually accomplish a few too many good things at less than 10% the cost. Therefore, in ET/ETI terms of which planet to plunder and pillage; is it going to be Mars, Earth or Venus? That part about my suggesting these ETs being a millions or so years older is only based upon whatever it'll take humanity, especially since we have no intentions of our NOT being at war, even if it's for an entirely phony baloney reason. Whereas if these ETs that I perceive as being on Venus were not of the perpetrated cold-war and make-war types, but otherwise focused their talents and perhaps their just as limited home-world resources as Earth upon the positive aspects of improving their quality of life and the advancement of their science, chances are they could be thousands of years less evolved and still they'd have space-travel nailed. Of course, there's absolutely no roon in the "Science Journalism Inn" for such nonsense. ~ Kurt Vonnegut would have to agree; 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.
