I have never made any claims with regard to the authenticity of that Apollo 8 video and you know it.

GeoEye operates at an altitude of 684 km (425 mi) above the earth and has the ability to zoom past .5M resolution. Take a look at some of their images on their site.
www.geoeye.com...
Remember, these are not their best images. They can zoom closer, but the US Govt will not allow sub .5M resolution images to be released. In a lower earth orbit, they could see even more detail.
SELENE was in a final circular orbit around the moon at 50-kilometres (31 mi). We can orbit closer to the moon, and we have technology that can zoom in far closer than what is being shown, so why can't we zoom in closer on the moon?
KH-11 sattelites were able to provide high fidelity images in the mid 1970's (down to sub .5 m resolution) and operated at a higher altitude than previous examples.
en.wikipedia.org...
KH-11 operating altitudes:
19 December 1976 – 23 December 253 km (157 mi) 541 km (336 mi) 541 km (336 mi)
23 December 1976 – 27 March 1977 348 km (216 mi) 541 km (336 mi) 537 km (334 mi)
27 March 1977 – 19 August 270 km (170 mi) 537 km (334 mi) 476 km (296 mi)
19 August 1977–1978 January 270 km (170 mi) 528 km (328 mi) 454 km (282 mi)
1978 January – 28 January 1979 263 km (163 mi) 534 km (332 mi) Deorbited
So, I'm just trying to understand why we cannot view the surface of the moon at even 1 M resolution. Even the lunar orbiter program in 1966 had the ability to zoom to 1 M resolution.

Which can only mean that you accept that it is authentic and proves Apollo 8 went to the Moon. Debate over.
You keep saying that, but the max stated resolution for the LROC is .5 M. So I don't understand how they got it to .25...

Now I can see that your terrible logic has gotten the best of you. If this were a real debate about the Apollo 15 video, would the moderator/judge allow the use your A8 video to counter my claim about the A15 video...? I don't think so. A fair moderator or judge would instantly rule your A8 'out of bounds

I don't get it. You just complained about it not even having 1 meter resolution, you then say it's 0.5.
In any case there are times when the orbit is lower than the nominal altitude of 50km. At 50km the resolution is 0.5. When it is lower the resolution is better. You could have read the caption for the image and learned that.

I will chalk this one up to, you don't know why we can't get closer. Will gladly say, that the photo posted, says the scale is .25M. I will also say that I do not think that photo was taken at .25M resolution.
Just because the max stated resolution is .5, doesn't mean we have photos that were ever released or even taken at that resolution.
I mean, they're saying that this old technology could produce .5 M resolution at 50KM... Well, GeoEye can go sub .5M resolution from 681KM
I mean, we really don't want to take high resolution photos of the cool stuff at the landing sites? We have the technology to do it, so why not? Instead we get a distant, grainy shot of the area...

Well it is at a 25cm pixel scale. They lowered the LRO's orbit for a short time during one of there station keeping maneuvers.
You can read about it here

Yes we do.

LRO isn't old technology. The LRO's NAC has an aperture of 198mm. Geo-Eye has an aperture of 1.1m. But Geo-Eye doesn't have to carry a bunch of other scientific instruments like the LRO does. There isn't room for a 1.1m mirror on the LRO. Getting higher resolution imagery from satellites depends on the size of the mirror and has little to do with technology in general.
Why, with our current capabilities and technology, can we not get a decent picture of the moon landing sites?
It is the only thing that I find odd about the moon landing site. We could get better photos of the area (from low orbit), but haven't. Seems strange to me. I, for one, would love to see some better photos of one of Americas' most historic sites, and we certainly have the technology to do it...

Oh, I get it. You think that hundreds of millions of dollars should be spent on a dedicated satellite to provide proof of the Apollo landings. Sorry, that isn't what science is about. I'm pretty stoked with the images of the landing sites (and the lunar surface) which are available.

if we have telescopes and satellites which can view distant galaxies

Galaxies are very large. Apollo artifacts are very small.
If you are interested you can do some research on angular resolution and what it takes to achieve it.

Visual imagery is only one of its functions.
I never said anything about a dedicated sattelite, though I thought the LRO WAS a dedicated moon observation platform (guess it's not).
Actually, I prefer the images taken at the time of the landings. Much more of a "being there" feeling.
I would love to have a high res photo of the area on my wall.
The images of the Moon are spectacular. Apparently you don't really understand what "a better camera" would entail. Apparently you don't understand the LRO mission.
I just find it weird that they didn't take better photos of the moon, or put a better camera on the LRO.
You are not debating. You are complaining about not getting what you want.
Not me, that's why I'm debating it until it makes sense to me...
