Apologies for not posting in the thread. My news server hiccupped and I
never saw the original. I'm cutting and pasting from Google. From: nathan jones ) | | The LM lunar surface probes attached to the landing pads | indicate the true last moments trajectory path taken | by the LM and if you look at AS11-40-5915 among others you | can see the orientation of 3 probes and the direction in which | they are bent ... Agreed, and this is the strongest evidence in favor of my hypothesis that the area behind Aldrin in AS11-40-5903 was "swept" by the DPS plume. First, the lay of the land. The LM lands facing west. There is therefore the west landing strut (forward), the east strut (aft), the north strut (pilot's right), and the south strut (pilot's left). The forward (west) strut did not carry a landing probe for fear it would bend and hamper egress and ingress. (All photo references are AS-11 roll 40.) SOUTH (LEFT) STRUT Reference photographs: 5850, 5860, 5887, 5927, 5928 The contact probe is sharply bent approximately 2 feet from its attachment point. The contact end of the probe is sticking up and pointing westward. The attached portion of the probe is bent northward and lies pinned beneath the footpad. There is a buildup of regolith under the left (south) lip of the footpad, indicating significant lateral motion in that direction upon landing. This is consistent with leftward (south) drift on initial contact and a combination of leftward (south) and forward (west) drift upon footpad impact. EAST (AFT) STRUT Reference photographs: 5892, 5914, 5915, 5925, 5926, 5927, 5929 The contact probe is bent from its footpad attach point, pointing toward the northeast (aft, and to the pilot's right). The probe shaft is straight, and the probe tip is approximately 1.5 feet above the lunar surface. There is a considerable buildup of regolith to the southwest of the footpad and evidence of compression to the northeast. This is consistent with leftward (south) and forward (west) drift upon footpad impact. NORTH (RIGHT) STRUT Reference photographs: 5858, 5870, 5901, 5902, 5903, 5915, 5917, 5918, 5920 The contact probe is bent pointing toward the north, and slightly to the west. The probe shaft lies along the east side of an east-west trench in the lunar regolith, which is approximately twice as wide as the probe shaft diameter. The trench has apparently been excavated by the probe to a depth of approximately the probe's diameter. There is a buildup of regolith on the east edge of the trench. The lower one foot of the probe is above the trench level owing to the irregularity of the terrain. The trench extends northward from the end of the strut approximately 1.5 feet. There strong evidence of compression north of the footpad. The compression pattern is triangular with the base forming the diameter of the embedded footpad and the apex pointing north. This is consistent with progressive compression of a cupped object drawn southward as it is lowered. There is also strong evidence of erosion from a laminar, linear fluid motion (esp. 5917) to the north and east of the footpad's final resting place. There is unmistakable evidence of regolith build-up on the south end of the footpad. The soil mechanics effects appear to have occurred in this order: (1) fluid erosion, (2) compression of the surface by a broad, cupped object (3) entrenchment by an object drawn southward, and (4) extension of the trench transverse to its axis. This order is inferred from the obliteration of portions of one effect by subsequent effects. This is consistent with a leftward (south) motion at footpad impact, occuring approximately the same time as a short (approx. 3 inch) motion to the east, causing the contact probe to push the eastern side of its trench further eastward (aft). WEST (FORWARD) STRUT There is insufficient photographic information to make any determination about the soil mechanics effects of the forward strut. Because the forward strut did not have a contact probe, there is a limit to how much information could be obtained from the photographs anyway. The photographic evidence of the contact probes and footpads shows conclusively that the lander was moving leftward (south) at impact. This is fully consistent with both pilots' testimony. | These do not correspond with the positioning of the hotspot | and the fluid errosion given that the engine continued to | fire untill just after it set down. Although it is Armstrong's opinion that the engine continued to fire after touchdown, that has been contradicted by guidance telemetry and by the visual inspection of the struts and the energy that was absorbed. In any case, the most severe plume effects -- both mechanical and thermal -- are observed directly beneath the DPS skirt (cf. AS11-40-5921 and AS11-40-5864). The photographs of this effect conclusively triangulate the discoloration and apparent center of the radial erosion pattern to directly beneath the DPS skirt. This is obviously the point at which the most intense plume effects are expected. However, that is not presumed to be the only notable effects. There is considerable evidence of fluid erosion in the area aft of the right (north) strut and to the right of the aft (east) strut. Similar effects are not noted in the other quadrants. This corresponds to the area on the lunar surface that would have been "swept" by the DPS plume in the final seconds of a forward-left final descent. If we interpret the photographic evidence according to the principles of flying the LM, a picture of those final seconds becomes exceptionally easy to see. The LM is always flown with some component of forward motion. You never fly backwards while you're hovering for the obvious reason that you can't see behind you. However, excessive forward motion results in a rough touchdown, and so the flight manual calls for eliminating almost all the forward motion just prior to touchdown. To do this in the LM requires back pressure on the control stick, which pitches the LM "nose-up". This is identical to how forward motion is eliminated when flying a helicopter. This manuever directs a portion of the thrust forward. In a "nose-up" condition, the rear contact probe would strike the surface first. If the LM enters this condition with significant drift to the left, the drag of the contact probe will immediately yaw the spacecraft to the left. It will also pitch the spacecraft forward, eliminating the forward braking thrust. However, Armstrong's forward speed prior to forward braking was only 4 fps, and so it would have required little pitch-up to eliminate that. The left yaw would have been corrected by rotating the control stick to the right. Armstrong's control actions here were, by his own admission, "spasmodic". He was overcorrecting many of the attitude errors. The final condition of the lateral contact probes is fully consistent with a right yaw that would overcorrect a left yaw induced by initial aft probe contact. If the spacecraft yawed to the right after footpad contact, the left footpad would "scoot" forward and the right footpad would "scoot" backward. The forward "scoot" of the left footpad would "roll" the contact probe forward, explaining why its bent tip is pointing forward. The rearward "scoot" of the right footpad would drag/roll the contact probe rearward, explaining the buildup of soil along the back side of the trench that probe dug. In short, Nathan, *all* the visible evidence is fully consistent with my theory, and there is a *lot* of that evidence. Since you listed the apparent discrepancy in the LM's final motion as the reason why you would not accept the possibility of a "swept" surface behind Aldrin in AS11-40-5902 and AS11-40-5903, it appears you're all out of excuses. | It looks more as if the LM was dropped in position onto | an already prepared ground made to look like it landed under | rocket power but unfortunately whilst dropping the Eagle it | wasn't accurately lined up with the pre-made rocket mess on | the ground. This is pure speculation, and it's not even good speculation. 1. Why would you carefully prepare a particulate surface for a soundstage and *then* put your major prop on it? As a theater and film man myself, I'd put all the major stuff in place first and then groom the surface. 2. Why would it be such a difficult thing to accurately lower a major prop? We have cranes in aerospace than can position things to within a fraction of an inch -- albeit very slowly. 3. The "pre-made rocket mess on the ground" lines up perfectly with the DPS skirt (in terms of the major thermal and mechanical effects). Further, the rest of the mess is *entirely* consistent with all the photographs and the landing film. It shows erosion effects right where the DPS plume would have passed over on the claimed trajectory. | No actual Moon landing implies floodlighting was used on a | moon "set". No, no, Nathan. You've changed horses, which is to say, you've changed your hypothesis in the middle of the investigation. That's a logic no-no. The original argument was that the apparent pool of light behind Aldrin in AS11-40-5902 and AS11-40-5903 must be an artificial flood light because it couldn't possibly be from any natural source. That argument requires you to expressly and specifically falsify each hypothesis that suggests a natural source. Remember, you have no *direct* evidence that a flood is being used here (e.g., a lighting cable or visible portion of the light itself.). You have simply proposed an artificial light as an explanation for what you claim is an anomalous lighting condition. You falsified heiligenschein, even though it really wasn't proposed as an explanation for -5903. After some discussion you were able to falsify spill from the aft equipment bay cover. Now the hypothesis in question is a DPS sweep of that ground. Now I have shown absolutely consistent, fairly conclusive proof that the DPS would have swept that area, and the illumination effects of having thus smoothed the surface are a matter of standard reference. You most certainly have *not* falsified the hypothesis that the DPS sweep is responsible for the optical characteristics of the lunar surface at that point. Instead you have tried to change the argument. Now you're saying that the photography doesn't give evidence of a credible or consistent scenario for landing, and that this belies an artificial setup which, necessarily, must have studio lights. That's not the argument you started with. Before you talk about whether the photographs listed above tell a credible story of Eagle's last seconds "air"borne, you need to bring to closure your indirect proof of illumination. I have shown you detailed, conclusive proof that the DPS would have swept that portion of the surface. The evidence is fully consistent on that point. This means that the bright patch behind Aldrin is *not* anomalous under those circumstances, but is in fact a natural and expected consequence of the sequence of events which Armstrong claimed occurred, and which the remainder of the photographic evidence substantiates. Thus it remains a very credible alternative to your indirect hypothesis that an artificial light was used. Remember, in your indirect approach you must *conclusively* falsify *all* competing hypotheses before you can assert the indirect hypothesis. Your inability to falsify it suggests you must concede it. And if you concede it, it follows that the lighting in -5903 is *not* necessarily anomalous. Your attempt at changing horses has further introduced a circularity. Earlier you were trying to prove that the lighting was artificial because that was the premise of your argument that the photos had been taken in a studio, or at least not on the moon. There was no artificial lighting equipment taken to the moon except for the flash on the Gold camera. Now you're trying to prove that the photos were taken in a studio (as evidenced, you say, by the allegedly inconsistent soil conditions) as a premise to the argument that artificial lighting was used. But that's simply the premise to the prior conclusion that a studio was used, therefore by attempting to rewrite your argument you have made irrelevant the entire issue of -5903's lighting. To wit: if, in the new argument, the photographs were taken in a studio, then *all* lighting effects would be achieved by studio lights, even the ones that exhibit no apparent anomaly. Therefore the issue of anomalies under that argument is irrelevant. Your constant flirtation with circularity is very strong evidence that you aren't attempting to disprove pro-Apollo evidence, but that you are instead trying to establish a certain definite conclusion in its place. You keep referring back to that same conclusion again and again, using a hodge-podge of ad hoc and frequently contradictory arguments. Clearly it's the conclusion you want established at all costs. | Regarding the "Hadley" images 10075741.jpg and 10075742.jpg | Anyone may examine them and try rotating them as you | described ... Yes, thank you for conceding that point. The point is that there exists a harmonious registration for those photographs. The fact that you can devise any number of *disharmonious* registrations for them is irrelevant; any pair of known harmonious photos will, if improperly registered, appear disharmonious. The existence of but one harmonious registration is sufficient to prove harmony in the photos. | and as for radiant heat I think I studied it well | enough at university. What university? What degree did you obtain? You say on the one hand that you have appropriate qualifications for your arguments. You say that you are an expert in the "queen of sciences," by which I assume you mean physics. These statements are made ostensibly to support the strength of your arguments. Yet on the other hand you say you do not require your qualifications in order to write to the Internet, and when questioned about them you become very evasive and defensive. This is not a consistent approach. Please either give your specific qualifications, or refrain from alluding to them in arguments. Further, you most certainly have *not* studied radiant heat transfer appropriately. Your error is fundamental and egregious, and would not be made by anyone who had successfully passed a college-level course in thermodynamics and heat transfer. The fact that your error has to be painstakingly and repeatedly explained to you is ample conclusive evidence that you have no appreciable expertise in radiant heat transfer. The time required for a surface to reach a given temperature while absorbing radiant energy -- other thermodynamic properties being equivalent -- is proportional to the angle at which the radiation strikes the surface (measured as an altitude angle). That angle determines how much energy per unit area is absorbed. If that angle increases, the absorption rate increases. The rate at which that angle changes affects the rate at which the absorption rate changes. If the angle changes rapidly from a low angle to a high angle, the absorption rate over time increases more rapidly than for a slowly changing angle. This means the surface will absorb more energy over a fixed time and will come to a higher equilibrium temperature sooner. This is why you cannot directly compare insolation characteristics between earth and moon. The earth's sun altitude changes an order of magnitude faster than on the moon. This is the main reason why surfaces on earth heat up faster than surfaces on the moon. Not only is this basic radiant heat transfer, it's basic calculus. Your inability to recognize the effects of differences in first and second derivatives makes it extremely unlikely that you have any prowess whatsoever in physics, which makes heavy use of these effects. You cannot be a dunce in calculus and a whiz at physics. | You'll see, the improved section regarding this will | be clearer. The lack of clarity in your previous example was only the lint on your fundamental misunderstanding of radiant heat transfer. Simply clarifying the same argument does not fix the problem. -- | The universe is not required to conform | Jay Windley to the expectations of the ignorant. | webmaster @ clavius.org |
