Acually, If you go to page one the OP had a link to his "questions".
My quote reply in blue was sourced by someone who had responded in that link. I thought the answers were valid.
PLEASE comment on any one of the questions!!! Or if any of the answers you think posted may be incorrect.
Thank You!! Jody
Well, Jody...
As you will quickly note, this thread can quickly draw "live ones" into it....We've got a new one I see, loaded with some pretty fringe ideas. I think Waspie, et. al. are dealing with that pretty well.
I think I'll answer your post, since it contains alot of somewhat typical HB issues that someone addressed.
My initial comment about them is that while fundamentally correct for the most part, the person who answered the questions seems irritated (naturally so, given the nature of having to repeat oneself over and over again...), and rather blunt, which doesn't lend itself to being educational.
There are some key questions here that can do with a little more of an answer.
For instance:

If there is no atmosphere in space, no wind on the moon, etc.... why does the flag move in the video ?
Conservation of momentum ALWAYS wins.
The moving flag issue. While conservation of momentum sounds pretty high-falutin', it's not explaining anything.
Try this:
Where the flag moves in lunar surface video,
it does so because someone is moving it. That's the answer, and it is observed
in all cases. An astronaut is manipulating the pole, carrying the flag assembly to its deployment location, or deploying the horizontal support, or twisting the pieces of the vertical pole together whenever the flag is seen moving.
Atmosphere or lack thereof has nothing to do with an object moving when a force is imparted upon it. That is simply physics. Move it...and it moves! It might even sway a little after the movement as its energy disappates, exactly like it would on Earth.
What is much more significant in the Apollo lunar surface videos, and of course is an aspect that HBs leave out, is that after the flags are deployed, they'rte on camera quite a bit (Apollo 11's flag was in view for the entire EVA post-deploy). In no case, ever, do you see the flag so much as twitch, even if an astronaut walks right past it. It sits there like it's a photograph of a flag.
This is because it is hanging there in a vacuum, where there is no atmopshere, and thus, no wind (moving atmopshere) to cause a flutter.

Why are the same backgrounds used for various pictures that NASA say are from areas that are supposed to be miles away from each other ?
Because moutains in the moon are GIANT and in order to make them no longer in the background, they'd have to travel a ridiculous distance. Also, it's VERY hard to judge distance on the moon's surface.
The actual answer to this is to state that the same backgrounds are not
used in the photos. The same backgrounds rather naturally appear in many photos on a given mission.
However, many photos on a given mission show the same, or similar backgrounds, because they are all shot in the same place, facing the same general direction.
On the Moon, there is a decided difficulty in perceiving depth, precisely because there is no atmosphere to speak of. The atmosphere here on Earth is an aid to depth perception, because it produces a haziness as distance increases. Some shots were taken facing the same mountains on Apollo missions, and the background appears remarkably similar. And, one shot may be a mile away from where another was taken. Examining such photos closely, you will see that the backgrounds do change slightly, they include more periphery, or less, and comparing the photos will also show that in many cases the background is a little larger or smaller.
But the camera is picking up the same detail if the mountain is 4 miles distant or 5. It looks just about exactly the same. Again, the Moon is an alien world. Visual perception is quite different there, including depth perception. Looking at this picture, for instance (AS17-134-20440)

....can you tell if that is a hill behind Jack there, or a mountain?
Of course not. But...it is indeed a mountain. It is called the South Massif, and is located approximately 4 miles behind the astronaut.
Kinda looks like you could just walk over there and touch it, eh?Across the horizon, you're looking at somewhere in the vicinity of five miles of lunar landscape. It would take most of us, on Earth, walking at a fairly brisk pace, about an hour to walk from where Jack is in that picture to the base of that mountain.
It's an alien place!
First installment concluded!
