why are there no stars in the background when astronuats do the repairs?

Answer 1

They are there -- they're just too dim to see. The camera is set to see the astronauts and whatever they're working on. Since that is pretty bright, the camera can't see the work and stars at the same time.

Answer 2

You must mean when the astronauts are televised. That is because the light that is shining on them from the video camera blocks the light from the stars. You can do an experiment from your yard or someplace where it is pitch dark at night. Hold a flashlight so the light shines directly in front of your face. You won't see stars doing this. Wait about two minutes, remove the flashlight and the stars will reappear again.

Answer 3

I have taken star pictures...you can too. What you need is the ability to hold the shutter open for about 15 seconds without moving the camera.
So, the answer to your question is that it takes an exposure time of a dozen seconds or so to get the dim lights that stars are, but the exposure used to photograph astronauts is about a two hundredth of a second.
(The guy who said that we never visited the moon offered, as one bit of evidence, the observation that there should have been stars in the background. Shows how much he knew about photography! (Or maybe he knew, but hoped his readers wouldn't.))

Answer 4

Same reason you can't see them during the day on earth. It's just too bright and the camera is trying to get a good picture of the astronauts.

Answer 5

The camera is focused on the astronauts, just like your eyes can only focus on near objects, not near and far objects at the same time.

Answer 6

cameras do not capture the faint light given off by stars.

Answer 7

because it is all a fluke
