They're not mock-ups. Those are all official NASA images, ostensibly from the moon's surface (See
AS11-40-5922).
To my knowledge, NASA has never claimed that any LEM Hasselblad-like photos (with reticules) were made using black sky or with a regolith simulant.
Other anomalies, such as below, left-to-right, showing:
1) a still encased Rover while Rover tracks are already present near the LEM (AS17-140-21370),
2) a Rover away from the LEM with no tracks in front or behind it (AS17-137-20979), and
3) two different pictures, said to have been taken on different days at different times of day, 4.5kilometers apart, one including the Rover (top), the other not.
You don’t think pictures of Mock-ups wouldn’t be part of the official NASA images? Typically there was more then one mock-up for a dimensional check. I’ve seen some very creative technical photographers in my time. Much of my own work was done solely from pictures. I’ve seen pictures of jet engine mock-ups you couldn’t tell from the real thing.
So you’re a non believer, ho-hum. I see a single track in that first photo. You do realize they took a motorcycle with them too. Americans are like that, lol. The other photos can be just as easily explained away.
There are other pictures of the rover unpacked sitting at the left from that same camera. It didn’t show tracks either. The track you do see is likely from the equipment rack they towed behind them (without the rover) for drilling and rock collecting. It had close spaced wheels. If you look close it appears as two tracks. They wanted to take a motorcycle to the moon, but didn’t, lol.
