It’s very puzzling that the moon landing had no stars in the background, the ISS clips have no stars in the background. I listened to multiple astronaut interviews speak on what it looks like up in space and about half of them speak of the “darkest black space”. I’m sure there is a very good explanation for this.
Is star light only visible through the medium of earth atmosphere? But once in the vacuum of space where there is no medium they disappear? What’s the explanation?

It is a matter of exposure and dynamic range. A sensor like a camera can only handle inputs in a certain range of intensities, and much of photographic skill (or smart presets) is about mapping the outside light onto this range so the details you care about show up rather than turn into white or black.
If you take a picture of a brightly lit scene, in order to make out the details of the bright parts (such as a lunar landscape, the Earth, the ISS etc) you will have to adjust the exposure making faint objects like the stars too dim to see against a dark sky background. You could try to set the exposure to show the stars instead, but now the landscape and Earth would be too bright (and likely also mess up the picture by causing flaring).
One can try to work around it by taking several pictures at different exposure levels and later digitally compositing them together. But this requires a lot of extra work.

Thank you for your input. That makes a lot of sense. I wonder what you can make of Neil Armstrong’s interview with the BBC 1970, the first minute into the clip should suffice, where he speaks of ocular testimony and not camera photographs, that no stars were visible except the earth, sun and moon. Possibly planets though he didn’t see any himself. m.youtube.com/watch?v=PtdcdxvNI1o

@Autodidact - Same thing. When you walk around in a brightly lit night-time city you will not see any stars unless you manage to shield your eyes from the rest of the glare. The lunar surface is very bright during the day.

Once again thank you for your response @AndersSandberg, makes a lot of sense. I’m assuming therefore that for the 8d 14h 12m that Neil Armstrong was in space he was always on the side of the sun, despite the interview saying that at one point they were traveling in the shadow of the moon eclipsing the sun 1:20-1:30 in the link above. I would have imagined that at that point stars would have been visible, but evidently the sun’s corona must have been still far too bright, or am I mistaken?
