so are you saying that this bright spot is seen in ALL LRO images??
originally posted by: choos
first of all, yes i have multiple times, you have continued to ignore it..
OBMonkey has also provided links to this that you have ignored multiple times.
originally posted by: choos
no one ever said it reflects upwards only.. it is just visible from a few LRO images because the LRO took images of those at the right time.
originally posted by: choos
so where is your proof of your theory that this reflection should be more visible the closer you get???

You clearly haven't read the links you have been given, or you would understand what causes the change in surface reflectance.
I even posted a photograph of a book from 1972 with the information you need in it.
No-one has ever said that the reflection of light is only upwards, only you have, so dump that strawman.

Do you actually have any QUOTES from these sources which explain all these points, such as
What makes the soil become more reflective after being disturbed?
Which specific particles in the soil are responsible for greater reflective properties?
How is it possible that millions of soil particles are blown about an area, randomly, over various distances, landing down on uneven ground, at various angles relative to the surface, yet manage to reflect more light only in an upward direction, in unison?
And finally, what proof is there for all of the above questions?
I've looked through all of your links, and have not found any answers to these questions.
Saying 'it's all explained in these sources, but you never read them', is utter bs. YOU need to cite from YOUR sources, to support YOUR argument. It's not up to me to sift through all your links, trying to find an explanation - which is not even there, to begin with.
You claim an area disturbed by the LM is more reflective than the undisturbed area which surround it, right?
While I'm waiting for you to explain how this is possible, let's go along with it, for argument's sake...
So when light hits those two areas, at the same time, at the same angle of incidence, they both reflect light in all directions.
If one of the areas has greater reflective properties than the other area, it will reflect more light in all directions than the other area reflects in all directions. Follow that?
No matter what the angle of incidence, this area will reflect more light than the other area will reflect - in all directions.
There cannot be a "right time" or "wrong time" for this disturbance to be seen, because it would ALWAYS reflect more light than the other area, in all directions, no matter what angle of incidence.
I said a real, physical feature on the surface, such as a crater, or a footprint, or a rover track, or a soil disturbance, should be, and would be, more clearly seen the closer you get to them.
Of course, that's why you are trying to twist the disturbance (supposedly) caused by the LM as not a real, physical disturbance. That it is merely a 'reflective' issue. Because in your world, blowing around soil over an area >200m in diameter doesn't mean it's a physical disturbance! It just reflects more light, after being thrown about!!
Right, of course!

I think turbonium would do well, if was to read just one of the links supplied, to look at this one:
www.researchgate.net...
While that links just to the abstract, you can download the entire pdf, and it does identify exactly what's going on and relates the details visible from orbit to those on the ground. It even very kindly picks out an Apollo 11 image to look at. There are even other references to follow that show how long this topic has been researched.
The 'blast zones' it describes are identified for all the Apollo landers as well as other craft, and the one of Apollo 17 is interesting given the photograph that choos posted some pages ago...

The paper says that Apollo surface images show higher reflectance around the LM's...with one image, that doesn't even match up to the images from orbit!
All the other images don't show a higher reflectance around the LM, but they point to one image that has a lightened area near the LM, which doesn't even match up to the area shown in orbit images!! And that's their idea of valid evidence??!? Sheesh...
You insist that this 'phenomenon' exists, and they have explained it....right?
What do they say in bold, about it?
They have no explanation for it, right?
So that's your job, to pretend they said it, even if they didn't say it, then??
It is all 'debunked' and 'refuted', thanks to you!!
But to claim - as they do in the paper - that the disturbed areas (around the LM's) can be seen in the Apollo surface images...is utter nonsense...
They claim a 'high reflectance streak' is near the LM, which doesn't match up to any of the images from orbit.
And they see a smoothed area near the LM, and this doesn't match up to the orbit images, either.
They have hundreds of other images, to support their case, but none of them are used in their paper....
Not because the other surface images show nothing of the disturbance, of course!!
In fact, the Apollo surface images show nothing at all of the supposed disturbances, caused by Apollo LM's.
None of the surface images even come close to 'supporting' their case - Not a chance.

That's not that they say. What they are doing with their work is using the change surface photometry caused by the exhaust from rocket engines to describe how the soil has physically changed. That's what they are continuing to work on, not that they are somehow mystified by the whole thing.

The quote you used illustrates exactly the point I said they were making.
Rocket exhausts change the photometric properties of the surface. Fact. Indisputable fact. There are many examples of it from numerous landing craft in lunar and terrestrial environments (remember you claimed that wasn't true)
The mechanisms producing that change are well documented and have been discussed for decades (remember you claimed that wasn't true).
Fact.
The changes themselves are well documented (remember you claimed that wasn't true).
Fact.
What they are doing is refining the understanding of those changes to allow for more precise modelling. Refining a model does not mean they do not have a model. Improving understanding does not mean they don't have any understanding.

They had the soil to show it exists, but only showed that it never existed, instead.
It's over, now.

No, they don't understand it.
What do they actually know - for a fact - about it?
They have samples of lunar soil. They've tried to duplicate the effect with lunar soil. They failed to duplicate the effect, however.
If they couldn't replicate the effect with actual lunar soil, that only proves the effect doesn't even exist, at all.
There is no proof it even DOES exist.
They only proved it doesn't exist, in trying to prove that it really does exist.. very ironic, indeed.
At the soil level, it failed to be replicated. No more proof is needed, just from that fact, alone.
They had the soil to show it exists, but only showed that it never existed, instead.
It's over, now.
Profiles for the Apollo landing sites, shown in Fig. 10, indicate that, outside of the LR-BZ, reflectance is greatest close to the LM, within 20–40 m, then tapers off with distance from the LM, reaching background levels typically at 70–140 m distance from the landers. The reflectance is lowest directly at the LM in the LR-BZ, where the astronauts disturbed the regolith, and perhaps directly beneath the landers where disruption of regolith by descent engines was chaotic.
The shape of each blast zone depends on the final descent trajectory of the lunar modules, and varies depending on whether they hovered above the surface or took a steeper approach to the surface.
A decrease in reflectance is observed in the area directly beside the Apollo lunar modules. This decrease corresponds to areas of astronaut activity, as well as the area where the largest volume of particulate material was likely removed, especially the areas directly beneath the landers.

So what you are suggesting as your reality is that NASA forgot to make the landing site bright as **** giving away the hoax.
originally posted by: choos
Even though they knew for a fact that the bootprint would compact the regolith therefore making the bootprints brighter and remembered to display this for the world to see in surface images.
Even though they knew that the engine would compress the regolith and deliberately took high definition images of directly under the descent engine.
They still just happened to forget to put in the bright blastzones not once not twice, but in every single surface image in existence..
That's your reality right?
