The LLRV/LLTVs balanced out 5/6ths of the weight, so they were operating at lunar gravity, not zero g. They could simulate the LM's engines, too, so the landings could be simulated, and there were, no doubt, times when the normal acceleration was zero g, not 1/6th g. Mary Thanks, you are, of course, correct. For some reason "zero G" was stuck in my brain. I could blame my recent stroke :-) Al Minyard |

It was ignored in fact. USSR was perhaps the only country in the world where "US moon landings" were not broadcasted live on TV. Michael US moon landings were broadcasting in USSR! You are just too young to remember. Yep, they were broadcast. I vaguely remember it when I was a kid. What I'd like to know is how widely Soviet space achievements (Sputnik, Gagarin, Leonov, Tereshkova) were popularized in the USA? Not at all. Sputnik created the space race...which Russia eventually lost, but you won't find a single yankee soul who knows who Tereshkova was. Not correct, I know who she was. She was a female cosmonaut intended to show the world how "emancipated" soviet women were. Al Minyard |

I remember some of the ribald ideas and conjectures that went around at the time. -- Rostyk |

I caught the movie "The Right Stuff" while channel surfing the other day. Although the movie is about American efforts to put a man into space, it managed to not mention Soviets even a single time! Not a single word during entire movie - neither before, nor after Shepherd's launch. Not so comrade , indeed the movie went to great lengths to emphasise the fear and paranoia that drove the Americans to invest so much economic and political capital in the program LOL. What a piece of propaganda! This is like publishing a book on American history and managing not to mention the Indians OR the British. Actually its more like a book on US history that doesnt mention the cossacks. Keith |

'Parachute packer in a can' as a 'first' is hardly something to be beating your chest about. Sour grapes? I believe that in addition to the obvioous political political purpose, they even manufactured a set of 'opportunity knocks' scientific, medical, purposes for launching her. As a slight parallel, What was the purpose of Senator John Glenns' 1998, STS-95 return trip into space? -- Rostyk |

"Michael Petukhov" wrote in message om... Not necessary. This is because you are not a scientist Keith. Otherwise you would know that humans never landed on Sun and other distant stars (at least officially) but its material compositions are known from spectroscopy data. Some elements (helium for instance) were first discovered on Sun and only after that was found on Earth. Spectroscopy will tell you what elements are present and in what proportions but can tell you nothing about the structure of the objects themselves. Diamond, graphite and hard coal all show up as carbon in a spctroscopic analysis. So what? But you know this Michael so you seem to be being somewhat less than wholly truthful. 100% truthful. NASA had tons of meteorites of different type. only from ANSMET program NASA got some 10000 Antarctic meteories Spectroscopy data were good enough to separate lunar rocks from that stock. BTW lunar meteorites have no single structure. It can be as different as basalts and breccias. As for the Lunar materials... well a standard marker composition can be easily measured by an automatical probe and results send here by radio. They did send automatical probes (Surveyors) to moon prior "manned missions", did'n they? Moreover it was easy to guess about some picularities of moon rocks, like extreme lack of water or free oxigen and certain minerals which are known to originate from nonexistent on moon processes. Given big enough meteorite collection it is easy to design such a marker set. Just a piece of cake, Keith! Nonsense Michael, this tells you nothing about the structure of the rocks, the density, crystalline structure, evidence of folding and distribution. All vital to the geologist. folding... of rocks you mean? As an example the microscopic pitting and high helium 3 surface content of the surface layer on rocks recovere by both the soviet and lunar sampling efforts was unexpected. These are believed to be caused by micrometeoroid impacts and interaction with the solar wind are unque to those samples retrieved from the moon as the meteorites of lunar origin have the surface burned away on re-entry No idea. Maybe. Although this was not mandatory to separate lunar meteorites from other types. by the way Keith so far NASA did not claim to land man on Mars or in asteroid belt rocks, but meteorites from all these places are easy to recognize and of course is on sell with certificates as well. Because since the 1960's much more advanced automated landers have been available. Good! So I record: Keith is agree that samples of moon rocks were not necessary to recognize lunar meteorites. So if you believe the Americans faked their samples by buying lunar meteorites they would have to know the nature of the lunar rocks or to fake or get the Soviets to buy similar fakes for their lander several years later. "If" is not a proper wording here, keith. They knew for sure. Hardly Michael , the surveyor probes which landed on the moon in the late 60's had primitive sampling mechanisms which were pretty much limited to performing soil mechanics tests. They were sent to check that the surface was hard enough to land on. The experiments performed were 1) Alpha Scattering Surface analyser used to determine the abundances of the major elements of the lunar surface with the important exceptions of hydrogen, helium, and lithium hm.. 2) Surface bearing tests using strain gauges , accelerometers and rate gyros I find it comical that you claim advanced automatic lab facilities capable of a full analysis were available when in you earlier post you were stressing how primitive the available computers were. Then Keith even more comic for you is that "Alpha Scattering Surface analyser used to determine the abundances of the major elements of the lunar surface..." sounds exactly like determination of the chemical markers for lunar meteorites I was talking about. Then of course their the problem of buying 400 kg of different meteorite fragments with nobody noticing. why? somebody was noticing. As far as I know so far no lunar meteorites were officially found in US soil while it is estimated to be around of a few % of all meteorites found today. Don't you think it is a bit of strange give US with US huge deserts? Since nobody knew what a lunar meteorite looked like until after Apollo 11 returned its precisely what any sane person would expect. If one have reliable markers it was easy to separate lunar meteorires from the rest and to know "what any sane person would expect" Although of course you don't. particularly given that NASA was known to buy lots of them from privat persons all over the world. I'm afraid all you did is demonstrate how prejudice can lead even intelligent people astary. Never say never, Keith. European SMART-1 is on the way to moon and japanese Lunar-A and Selene are getting ready to follow soon. They can send us very unexpected pictures of Apollo landing sites. US privat company's "TrailBlazer" can do in principle but who in a good mind can trust US data? Not me at least. Doubtless you'll use some other excuse when pictures of the Apollo Landers are beamed back. We will see. I do not know how about you but I am looking forward to see that. Michael Keith |

Give it a rest. The most probable origin of NASA moon rocks is the moon.
Going to the moon and picking up some rocks is just simply far easier and cheaper than the elaborate scheme that would be required to fake it. Occam's razor! |
