And if really, they may have cancelled measurements. The LRRR are still available. It is nothing special that scientific experiments are cancelled. Maybe we now have a theory of lunar movement which fits and predicts distances with an accuracy better than the accuracy of the measurements. Until we can't get more precise measurements, it doesn't make much sense to continue measurements.

Here's more information on the laser ranging process, with some graphs of the return signal:

Whats cool to me is that we are counting only the 10's of protons returned per pulse.
I think you mean photons.

Right, note to self, do not leave BAUT thread unattended for two days as you will then have to do a huge reply in one.
SpitfireIX Was "truther" his term? I'm curious because in conspiracist and debunker circles a "truther" (or "twoofer") is someone who purports to attempt to uncover the "truth" about the September 11 attacks. It was indeed. He put it in quotation marks. I did think it was odd, but the entire email was odd... JayUtah The word 'amateur' is mighty useful sometimes, and if used, should be backed up by expert opinion. Yes. I have no problem with people calling themselves amateur space historians, or even armchair engineers. The problem is when their conclusions butt up against the commonly accepted views. If all the qualified engineers believe that the LRRR would work, and one "amateur historian" mounts some pseudo-technical rationale for why it wouldn't, then the parsimonious resolution to that controversy is that the lesser-educated guy doesn't know what he's talking about -- especially if his errors can be demonstrated as was done here. The reason I said about his "theories" surprising me is because it does. I'm a history writer, specialising in the Tudor period, and I learned a valuable lesson while I was a student: if it isn't written down by someone who knows/knew, it doesn't exist. If you don't know yourself, you need to piece it together - but you need to judge the value of the evidence presented. Now, say I was him. I hear about retroflectors. I think, jeesh, that sounds odd - one tiny bit of light reaching the moon? My next move would never, never be to post a blog trying to convince people of my sudden burst of inspiration. I'd go and see what the experts had to say. And as some of you have pointed out, if he'd just watched Mythbusters he'd've had his answer. This kind of, well, non-thinking, baffles me and goes against everything I've ever known. What he's done is elevate his own thinking above that of someone who is experienced and knowledgeable. I just can't understand it. Various: my general ignorance to conspiracy theorists' and their ways Trust me, I'm learning. I saw Apollo 13 when I was nine years old, and I loved it. I read 'A Man on the Moon' when I was 12. I became an Apollo fan, basically, and sought to learn more. Not through any scientific interest (God, that'll get me beaten off this forum) but through the majesty of what Apollo achieved, the poetry of it. Maybe I should have focused on the science, because I can admit that when I saw the Fox documentary, I was blown away. Because, to someone who isn't scientifically-minded (I failed all sciences and maths, passed anything to do with the written word with merit - science + me = not good friends is about the only equation I can understand), that documentary was convincing! I didn't know any better! So I watched it and I felt sad, like I'd had something taken away from me. That hurt so much I set out to "debunk" for myself, by reading and reading and reading, even forcing myself to understand scientific radiation explanations. In this, I'm still an amateur, but if you want to know something about an astronaut's feelings, emotions or experiences... I'm a very good amateur. So yes, the conspiracy theorists still surprise the hell out of me. I don't understand why they do it, and why they seek to back themselves up with such flimsy nonsense.I appear to have come across as naive, which I'm not... I'm just not immune to feeling actually hurt by what these people say. I believe this is because I came to Apollo from an emotive rather than scientific perspective to begin with. Still, give me a few more months on these forums and I'm sure you will all have shaken that out of me ![]() |

![]() Actually, that is probably the saddest part of the Hoax Believers. Here we have one of mankind's greatest adventures (at least till now), and not only can they not appreciate the poetry of it, but they belittle it by making it a dark and evil thing. And yes, even the scientists feel the poetry of it too.

...do not leave BAUT thread unattended for two days as you will then have to do a huge reply in one.
The trick is once you leave it for two days, leave it for months. I took a six-month hiatus from all my online activities a few years ago to care for my father. I just picked up anew. I don't think anything really got left out. I'm a history writer, specialising in the Tudor period, and I learned a valuable lesson while I was a student: if it isn't written down by someone who knows/knew, it doesn't exist. And even then it's iffy. The documentary record of Apollo can be inconsistent, as is all documentary history. But in my case I have dozens of contacts, to any of whom I can send and email or make a phone call to get more information that helps resolve a conflict or question. If the documents list different dimensions, for example, for the LM forward hatch, there are people at the Cradle of Aviation museum, for example, who will cheerfully go measure LM-13's hatch. Or in that case, point out that it's difficult to determine which "edge" to use as the top of the hatch. Imagine if you had only the documents to go from. If you don't know yourself, you need to piece it together - but you need to judge the value of the evidence presented. And that really never goes away. In my role as a forensic investigator I have to perform an historical piecing-together, but for events that may have happened only hours ago. It's difficult to avoid allowing your emerging hypothesis to be the "filter" that determines the value of evidence: hey, this doesn't fit my theory so I'm going to discard it. This is why we investigate in teams, where possible. We want to shake out prejudices. And this is the modus operandi in academia too. We review each other's work to make sure it hasn't been preconceived. I'd go and see what the experts had to say.... This kind of, well, non-thinking, baffles me and goes against everything I've ever known. What he's done is elevate his own thinking above that of someone who is experienced and knowledgeable. I just can't understand it. Right; it takes a while for the seasoned scholar or researcher to wrap his mind around the conspiracist mentality. Naturally you're projecting your methods and motives onto them and then wondering why it doesn't fit. Conspiracists aren't seeking a deeper understanding or an assurance of correctness. They are seeking a validation for belief. Pseudo-scholars tend to define themselves as "true" researchers, and to define the mainstream as a stagnant, largely self-serving system. They really don't see any legitimate value in educating themselves, because they define formal training or education as little more than indoctrination. They consider themselves naturally and inherently "in tune" with the universe, often precisely because they haven't been contaminated by "closed-minded" mainstream thought. Consequently often they'll throw around terms like "common sense" to indicate that the mainstream is allegedly so out of touch with reality that even the untrained layman can see it. Pseudoscientists and pseudo-historians tend to work alone. They don't benefit from peer review. In fact, they eschew it. To the pseudo-historian, peer review among mainstream scholars is just a way to homogenize research and do away with any radical ideas. The psychological reasons for this appear to be many and varied. Ego-reinforcement appears to be a common motivator. The pseudo-scholar wants approval and recognition for his skill, but for whatever reason cannot achieve that within the ordinary scheme of scholarship. |

In fact, I was walking home last night under a beautiful, golden, waxing gibbous Moon, and all I could think was, "It is totally amazing that, forty years ago this summer, there were men up there." I told the friend walking me home about the Lovell thumb, and he agreed it was pretty cool. I can't cite you figures on radiation or engine thrust. I'm the wrong person to talk to about cameras and telegrammetry. But I can talk for days about sheer scope. Apollo 11 was seven years before I was born (which doubtless makes some people cringe the way the age you were when you saw Apollo 13 made me), but I am still in awe of it. Even if we go back, the awe will never go away for me.

That's not correct, Henrik. Hubble can and has imaged the Moon on several occasions.

Checking further, it looks like I was wrong.
I stand corrected.

More on topic, the whole issue of precision aiming is pretty silly. Even aside from the laser beam spreading, does your correspondent have any idea of how astrophotography is carried out? Maybe some reading on it would bring him some much-needed perspective. |
