How interesting!
The Earth's atmosphere looks strangely reddish, with a thin layer of greenish-blue on top.
It seems to me that the belt stars, which are seen through the atmosphere, should look reddened. No such effect can be seen. though. How fascinating it would be to have some fast and super-sensitive photometric equipment on board, which could measure the B-V of the belt stars when they are seen through the atmosphere, and then repeat the measurement when the atmosphere is no longer in front of the stars. What would the difference be, if any? Oh, there really should be some difference, I think.
