Please drop the "I am a scientist" bit as I am not in the least interested and don´t believe it for a minute anyway. Testing the rover battery my arse! How could you expect a 40 year old wet battery to be even in one piece? Total crap! I have had treatment thank you, and reasonably successful too. I had radiotherapy to reduce the tumour sizes and relieve the back pain, still good after 8 months. I have a hormone suppressant injection every 3 months and daily medication to stop feeding the cancer and so far I am in remission doing okay. I should get another 4 or 5 years with any luck before it eventually kills me, which it most certainly will. Enough of this diversion. What is your view on another moon landing mission? Think the Obama budget will allow it and would it be worth the cost anyway? I don´t think it would serve much useful purpose, in the same way the ISS is an unbelievably huge waste of money. |
| Posted By: john Posted On: Aug 19, 2009 Views: 1214 | RE: lunar equipment nice to hear from you. we didnt test the lunar rover batteries. instead, my colleagues did some experiments with substances comparable to those used in the batteries. and, as expected, they couldnt get them working at extreme temperature regimes. we were wondering how those batteries worked in the outer space without any active temperature control. anyway, i got interested in the history of space technology. i m going to read the book Williamson, Mark Spacecraft Technology: The Early Years . --sounds cool. it's funny, but i am not really interested in any current or future activities in space. as i said, i am fascinated by early years when they shut those astronauts into space without any clear concept of how and why they were doing it. it seems all this was very much inspired by the historical (political) circumstances around the cold war. now we do not have such luxury to throw away enormous resources in order to let someone to play golf on the moon. anyway, i guess that sooner or later private commercial companies will make it to the space. but what are we going to do there? i guess people do not really need it unless something substantial on earth (like the cold war) pushes them into that direction. i am also fascinated by your perception of scientists. you seem have some almost religious attitude towards this profession. even giants like newton were not specialized enough to see outside their field, what you expect now? all i can say from my perspective is that we miss some logic in the development of the apollo project. from scientific point of view, it was almost a failure: no one cant repeat it anymore. which is pity and strange. this is all i am trying to say. |
| Posted By: Keith Mayes Posted On: Aug 20, 2009 Views: 1205 | RE: lunar equipment 1) "anyway, i was just trying to tell you that the damned batteries dont work in our lab at -100C. and the temperature distribution on the lunar rover was, and still is a mystery. we will need to spend 3-4 years on modeling to find out" 2) "we didnt test the lunar rover batteries. instead, my colleagues did some experiments with substances comparable to those used in the batteries. and, as expected, they couldnt get them working at extreme temperature regimes. we were wondering how those batteries worked in the outer space without any active temperature control." I see. You need to explain why your "lab" team are trying to duplicate the battery used on the lunar rover. For what useful purpose? The technology is 40 years out of date. Why would you want to know "temperature distribution on the lunar rover" so badly that it´s worth "another 3-4 years modelling"? What for? What use is it unless you intend building another rover and putting it on the moon? Please explain, I would love to know! |

I am sure there must be a huge demand for them, its not like there has been any technological advances in the last 40 years. The guy is a raving loony, he needs psychiatric help. |

| Posted By: john Posted On: Aug 26, 2009 Views: 1186 | RE: lunar equipment you guys are a bit arrogant with respect to the scientists. we dont work on another lunar rover. we work on nanodevices, as many do now. there is a certain problem with fabrication of those nanostructures that can be comparable with the problem of silver compounds under extreme temp conditions. i just found out that the developers of the "lunar rover" might have had the same problems. i was surprised to learn that there is/was no detail explanation of how they would solve the problem of silver-zinc battery working without active temperature control. this makes me think that some parts of the apollo program were fake simply because they didnt have enough time to develop the needed technology (and even if they did, we do not have any clue how they did it, which is weird). that's all what i say: if it was true, then we have lost it forever, as if it never existed (only on the tv screens). anyway, it's a fascinating subject. again, i say "thanks" for keith for maintaining this website and letting us talk. |
| Posted By: Keith Mayes Posted On: Aug 27, 2009 Views: 1180 | RE: RE: lunar equipment This happens a lot. People come onto this site and say they can´t understand this or that detail, they say they know the landings happened but seek just this one explanation. Eventually it comes out, they are hoax believers and just try and slip in under the radar. That "john", is where you are, you don´t believe it happened. You try and sound convincing by saying you are a "fairly well known scientist" and claim to be testing the lunar rover batteries, which later become testing similar substances. No one who has had a decent education and has a reasonable working brain can believe that such a massive and well covered and well documented project as the Apollo programme could possibly be faked. Going to the moon was not easy, but it was a lot easier than attempting to fake the whole thing would be, or even a small part of it. Whatever "problem" you think you may have "uncovered" is in reality not a problem, it´s your perception that is the problem. The moon landings happened, it is a historical fact. We even have new images coming in showing the landers on the lunar surface, something the hoax believers have been crying out for for many years. No doubt those same idiots will now say that the shadows are in the wrong place.... Go away "john", you are just another of those hoax believer idiots. No doubt you will say that the images showing the landers are fake. That would show just how dumb you really are. BTW Your lack of capital letters and very poor sentence construction - if any - is something I would expect from a daft young kid, not a ""fairly well known scientist". Stop pretending and grow up. |
| Posted By: john Posted On: Sep 4, 2009 Views: 1164 | RE: lunar equipment i agree that it was "a historical act" and it was pretty much documented. i have my doubts whether it was "a scientific act" - this part was much less documented, to the point that no one can repeat the whole thing anymore. i only say that from the scientific point of view it was almost worthless. now we need to re-invent the whole technology again and the risks are not minimized by the fact that we did it 6 times before without any failure! (btw, this is almost unbelievable thing now if you look on how dangerous the shuttle program has appeared to be). anyway, it is a bit ironic, but i think that the ability to question things is the ability of a real scientist, isnt it? why should we believe to those highly politized accounts made in the time of the nixon administration, especially if we see that our current technology is behind of what was possible 40 years ago? therefore there will always be people who keep questioning all this. it would be nice to see the real pictures of the lander, i would be happy to see them. i want to be proud for those who landed on the moon. |
| Posted By: Keith Mayes Posted On: Nov 20, 2010 Views: 1029 | RE: RE: lunar equipment I was watching a documentary this morning about the Moon landings, and one of the topics covered in detail was the development and testing of the lunar rover. Controlling the temperature of the batteries was simple. The batteries were protected by a gold(ish) foil over a padded covering. The batteries were surrounded by containers of pariffin wax which absorbed the heat during operation and melted. When finished with for the day, the padded panels were lifted so the heat could escape and the wax solidify again ready for the next day. So simple yet so efficient. |
