If it was so super bright, surely it would wash out all the small detail to be seen?
But its the same wierd light conditions that can select which 'shaded areas to selectively' illuminate.
For crying out loud....even the camera maker is baffled as to how they got the pics they did, as is the manufacturer of the suits who when asked to construct suits for use in a radiation environment, said they couldnt do it.
Just once I would like someone to admit that they are baffled by an aspect of the project, rather than blindly trotting out some mantra to head off some 'truther' or other.
If someone clearly explains away a query to my satisfaction, great, thats education, but the moon landing thing has way too many questions to be squeeky clean.
Roswell....now theres a fairy story.
99 % of UFO 'spaceships' are baloney for me, the apparent evolution from biscuit tins, through Ed Walters polaroid lampshades, to the CGI creations of today take some explaining.
But it still leaves 1% of 'something' to look at objectively, thats all, 'V' isnt real....yet! But we can at least discuss these things without just getting into a 'Oh no its not Vs Oh yes it is' contest.

I've always wondered how this works, since too much oxygen normally causes humans to go light headed..
Does this mean that thier breath is short since they don't have to take other gases onboard such as our air??
If that's the case it must feel really wierd...
All the best,
It works because partial pressure of oxygen is the same in space suits and on Earth. Earths atmosphere has a pressure of about 100 kPa, with partial pressure of oxygen of about 20 kPa. The rest (80 kPa) is mostly inert nitrogen, which you dont need to breathe.

Erh...what happened to your off topic rule?
No, you can't see stars with your own eyes in space because they are too far away. The angular diameter of the biggest star in the sky, Betelgeuse, is 50 milli- arc seconds and the angular resolution of an human eye in 60 arc seconds. Therefore, the angular diameter of the largest star in the sky is about 1000 smaller than the resolution of a human eye! Then You can't see star when you are in space. It is comparable to trying to look at a 1 dollar coin (2 centimer diameter) located 200 km away from you - you can't simply resolve it!
You can see stars on earth thanks to the earth's atmosphere and the integration time of a human eye (few milliseconds). The atmosphere turbulence and multiple layers of different temperature will disperse the light beams coming from each star due to a series of refraction effect. After few milliseconds, the human eye would have observed many photons coming from the star that have been dispersed on slightly different angles each other- it looks like that the light beam of stars has been spread. And the diameter of this 'stain' on your retina is comparable to human eye resolution.. You can see it !!

The optics were primarily cameras, using specialized filters. They were also two optical telescopes in the Lunar Module for navigational aids.

They did ask them ... and this is what they had to say ... also can anyone answer what these 'optics' are he talks about.
