WHAT'S NEW Robert L. Park Friday, 6 Jan 06 Washington, DC DEEP SPACE CLIMATE OBSERVATORY KILLED. http://bobpark.physics.umd.edu/index.html -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

I like the URL and where they are going with the imagery:
http://blueturn.earth/ https://vimeo.com/173723357 On another note pertaining to the character of the blueness of the Earth, I can offer the notion that the ground view of the overhead sky with thin scattered clouds (and the sun at a moderately low altitude) is rather similar (with a bit of imagination) to the space view looking straight down at the ocean. If you have a lot of imagination you can get a sense of vertigo looking up such a sky - and think you're really looking down. Thus I'd consider the contrast between the darker blue and brighter white should be less than what we see in the videos above, assuming we want the display to be linearly proportional to the actual brightness. -------------------- Steve [ my home page and planetary maps page ]
