For Harry_h:
The moon is typically very gray and is the color of asphalt. While there are deposits of stones of many colors, for the most part gray dominates. There are stretches of orange colored soil and yellowish soil, and even a patch of pale greenish soil has been reported. Samples of all were taken and brought back for analysis.
For Doran Williams:
This is very simple. If you are exposed to bright light, your pupils will contract to eliminate potential damage to your retinas. Camera "auto-iris" circuits also change the sensitivity of the camera to render it less sensitive so that you can see more than a bright blur.
When the cameras iris is contracted, the less bright objects will not register- and hence, the stars (which are very pale compared to the sunlit landscape) will not register. Go outside at night with a flashlight, look at the stars, and then shine the flashlight at your eyes. The stars will be difficult to see at best, for the same reason.
For orin stepanek:
Yes, in Houston the samples were used for all sorts of biological experiments. Plants exposed to lunar regolith (which is ground up rock with no organic matter in it) grow very rapidly. This is in part because there is no lack of trace elements in it, and these minor constituents can have a dramatic effect on plant metabolism. In our soils, these materials are washed out, bound in chemically, or taken by other organisms. Ever note how "rich" volcanic soilds are? Same reason.
In the same experimental facility, they also raised turtles at 1.5 PSI of air pressure and did so successfully. Many "lower" animals have the capability to survive incredible conditions. These experiments were part of the effort to find out if plants and animals could survive in space colonies and what their limits were.
For HashishAssassin:
Since the image is a panoramic one, and the camera is located at one stationary point, clearly the shadows must point in varying directions. Picture the scene from above- all the shadows are parallel. Now, pick a single point in the middle of the photo and rotate a line around it (like the viewpoint of the camera). The angle of the shadows will only be parallel at two points; at all others, the shadows will be cut at some angle. Simple.
Have a great day.
