Inquisitivemind, how about a different approach? Imagine the CSM orientated so that the SPS engine bell is pointed at the Moon and, with the LM still docked, the DPS engine bell pointed away from te Moon. Now, calculate the Centrifigal Force Differential across the length of the complete spacecraft, as per your original post. Now calculate the resultant torque and show us how tat would force the complete stack to assume the "horizontal" attitude you talk about. Some figures to start with - CM height 3.23m, SM height 7.41m, LM height 6.98m. CM mass 5900kg, SM mass 24500kg, LM mass 15440kg (Apollo 11 LM would have been a bit less than this). Radius of the Moon 1737.1km (Mean), orbital heigt 96.6km (circularised). Go to it.

inquisitivemind, you talk about the Moon being an "unknown universe." That is not really true. Don't forget, five Lunar Orbiter probes had mapped 99% of the Lunar surface, specifically to identify potential landing sites. Resolution was as good as 2m for te pre-selected target sites that were deemed most suitable and so potographed in higher resolution. The Surveyor programme then soft-landed 5 probes to investigate the nature of the Lunar surface in more detail. Apollo 8 flew by the Moon in 1968 and also took photographs and other measurements. So did Apollo 10. The upshot of all this is that, by the time of te landing of Apollo 11, the Moon could hardly be described as "unknown".

I can't shake the conviction that this is a stunt. The footage has been doctored using CGI to add the figure specifically to use as a vehicle to get this chap's company in the public eye. He starts off by introducing himself and his company and the work it does, and is posing in front of a poster advertising a film. Does anyone have access to an older copy of that Chaplin film and can have a look?

I laughed when I first heard this Time Travel idea. My instant reaction was "who on Earth is she going to be calling?" Who else, in 1928, is going to have a mobile? Where is the mobile phone infrastructure required to make the things work? I haven't seen the video yet, it's blocked by our company firewall, but I will have a look later. Is the woman adjusting her hair? Getting an earring properly seated? Maybe she has an itch?

I think it should be a rule on here that if anyone posts an Apollo picture, they should either post it as a link to the ALSJ, or at least give the relevant Apollo photo reference. Rodin (and others) are posting links to pics they have put on Photobucket or similar, and I can't see them at work when scanning the thread in my lunch break 'cos our company firewall blocks out sites like Photobucket... sorry, rant over....

So Brucel is another of those HBs who would rather invent a whole new form of Physics rather than admit to the possibility that, just maybe, Men may have landed on the Moon.... how many new branches of Physics is that now?

Brush it (regolith) under the carpet now. Or rather rocket bell. It was old man Withers I tell you, would have got away with it if it were not for the pesky kids. Inded his latest one is a hoot. He has "identified" striations under the bell that he says was caused by a guy with a broom. It appears the striations travel in different directions so the broom-guy must have been blind. Those striations, they don't happen to go out radially from a spot under the approximate centre of the engine bell, do they?

Beautifully put. Is there really any need to say any more after that?

The book doesn't go into that much detail, but that would sound about right. I'm sure there are other sources that could expand on it. But.... only 4 moving parts... that's pretty neat....

Hence the reason it had about 2 moving parts. Strangely enough, I'm just re-reading the Haynes Manual for Apollo 11 and have just reached that bit. The ascent engine had a total of 4 moving parts. Not that the fine detail matters - the important bit is that the designers knew what they had to achieve and worked out how to do it. It's just engineering. The same goes for the rest of the Apollo programme. It's just a shame others can't appreciate it.

www.nasa.gov/topics/earth/features/roving-rocks.htmlLeaving trails behind them, rocks are believed to ahev moved there at the deesert but 'normal' caused like wind, animlas assistance, aerthquakes were ruled out by scientists. I read this article on anotehr forum where they were discussing moving rocks by sound vibrations or so as an explanation to building the pyramids and two persons were being debated, one of them is he builder of Coral Castle . Controversial, but desrves comments. Any thaughts? Actually, that article didn't rule out wind assistance - they did rule out animals, gravity and earthquakes. Wind is still the favoured force being applied. The question is about how the friction between rock and surface is reduced enough to allow the wind to do the job. A fascinating study.

Love it! I always thought that last goal was a bit off...no, sorry, that's the current world cup!

... If the Moon is a space vehicle then why is not Earth a spacecraft too?/ First, you have to provide the evidence to show the Moon IS a space vehicle....

by the way, here is another story. When I was at school, I was walking thursty in the playground, not having enough money to buy juice. I was thinking all the time about pineapple juice, the one of the brand name called Mr Juicy. I didn't have the money, but I asked the 'universal law' [call it whatever you want] for that pineapple juice. after fwe minutes, two girls approached me holding one Mr Juicy container. one of the two girls said: I bought this but I don't want to take it, so you take it. I told her give it to your friend [the girl with her]. she said : no, she doesn't want it. you take it. as I said I still have plenty of stories.. so I believe because I touched.. I understand thta you don't want to believe in something that doesn't have scientific proof that is established or stuff, but I can't think of this also t obe coincidence. And what evidence do you have that that girl would not have done that anyway? What evidence can you show that proves that it was your wish for a drink that made her buy that wrong jiuce and offer it to you?

but then reopening them is as equally dangerous No, you just limit the access to the areas known to be the least risky. It sounds like a fascinating place, whatever the stories. Worth a visit if I ever get to go to Malta.
