I'm just wondering, how many GLPers believe the SPACE SHUTTLE Program is another HOAX like the Apollo-11 HOAX Program?

[quote:Astronut:MV8xNDYwMzk2XzI0MTA2MzE4XzJBOThCN0Q3] [quote:Anonymous Coward 1155273] Why don't they ever see stars? I would think they would be an absolutely beautiful panoply of them somewhere along their orbit. Would you explain why NASA never seems to capture them on film on any of it's missions. [/quote] Stars are quite dim, particularly compared to daylit objects. It's all about dynamic range. If you're inside the shuttle and the lights are turned on, your eyes will not be "dark adapted" and you will not see much in the way of stars. If you're on a spacewalk on the daylit side of earth, the light reflecting from the earth and even your own spacecraft will tend to blind you to the stars. Once you're on the night side you're working with flood lamps to see what you're doing, so you still can't get dark adapted. Now there are cases where astronauts have carefully used long exposures to record stars through a window while blocking out any bright light source, but it still required just that; long exposures. A standard video camera is not going to be able to do that and even a low lux camera designed for the task will need to be shielded from all possible bright light sources or it too will be blinded from seeing stars. In the end you don't benefit much from being in space as far as widefield astrophotography goes. In fact, you have to contend with the fact that your spacecraft is generally holding a certain attitude as it orbits the earth, so you can't expose for as long as you could if you were on the ground and shooting from a telescope tracking the stars' motion. The small amount of extra light doesn't register as a linear increase to your eye, and the extra light also applies to the bright light of the sun and moon. The real benefit to being in space (at least as far as visible light astronomy is concerned) is that you don't have to worry about atmospheric seeing, but to reap that benefit you need a long focal length telescope like Hubble.

Mathematically speaking it adds up.
1 hoax + another hoax = 2 Hoaxes.
