Ok, on the videos of the men walking on the moon, you can see through their bodies and see the other side where the moon and the lander and such and such, are. Does anybody know why this phenomenon occurs?

'state of the art' technology was using a modified video cam, with a cathode-ray tube, which had difficulties to get along with the bright light.
a contributing factor to the poor quality is the fact that EVERY motion picture you may see about the apollo missions was filmed from TV-screens, cause there was no recording standard for video at that time.
the cameras where non-standard too, which means they had an alternate row/column ratio which isn't PAL or NTSC-conform.
Nasa recorded vast ammount of this video-data onto magnetic tapes which were useless at that time cause filming it from the screen was way easier to accomplish.
For not having a suitable equipment to retrieve video data and not really having the need to retrieve it, Nasa stored those tapes somewhere and lost track on them.
lets hope they find them, cause now we would be able to read them using computerized-equipment

Because of the way the camera worked, if an image was static for a long time it could 'burn' the image into the video tube. Because the camera was left pointing at the LM for ages the image of the LM became burned into the tube, hence it still appeared even when an astronaut walks in front of the LM. It's purely a video artefact, and more than that it's purely an artefact of the Apollo 11 TV system. Lets missions did not suffer this, partly because of improvements in the TV system, partly because of having mobile cameras.

It may be caused by defective video. Or maybe you become transparent when you land on the Moon!

I know what you mean. It must be an optical illusion of some kind produced by the poor video quality.

By my chosen name, you can guess that I am a space geek. I have seen hour after hour of NASA moon footage, and have never noticed anything like that. What videos are you watching that it is like that?

Poor TV transmission technology back then.

I watched when it happened and I don't remember seeing thru anyone. Maybe it is old photography--who knows.
