Red Dawn. Red Sky
After thousands of years of looking at blue skies, are there any anticipated
psychological challenges awaiting Martian astronauts waking up to a red dawn and looking at red skies all Martian day ?? From pictures taken by the various Martian landers we get an idea as to what a Martian day looks like. Kind of strikes me as an overcast look to it. I know how I feel after a few days of no sunshine, cloudy skies. Will Martian astronauts have to deal with the "blue-less sky" blues ?? Jeff Lerner |

Unlikely since most pictures from Mars tend to falsely shift the color spectrum to the red. Look at the latest Discover for an article on this. The sky is far more blue than most pictures make it look. Jeff Lerner |

After months cooped up inside the spacecraft, I warrant that *any* sky will be welcome. I suspect the greatest time of spatial stress will be when the re-coop and start home. D. -- Touch-twice life.

I've seen plenty of plenty of colorful dawns and sunsets; I live in the Pacific Northwet, famous for its cloudy weather (but not in summer!). Darkness and low light levels do have a depressing effect on many people. I expect Martian explorers will get used to whatever conditions are present, though maybe NASA should investigate how to most efficiently concentrate coffee/caffiene... --Damon |

That might make an interesting study- stick some volunteers into a reddish low light room for a few weeks and see if they have any unusual psychological responses. It's going to make a difference in color perception, particularly if their spacecraft uses Earth-type colored light inside. I was at a party once where the room was lit by a red neon fixture; on going outside the Moon appeared to be bright green. Pat |

If you've ever been in a partial eclipse of the sun on a clear day where most of the sun's disk gets eclipsed, you might have experienced something similar to Martian lighting conditions; the effect is completely different than that of a thin cirrus overcast, in that the light stays sharply focused and the shadows things cast are sharp- but the whole contrast between light and shadow is decreased. It's a very odd sensation, and could take some getting used to. When I was a kid this happened to me once....and I thought it was the end of the world starting. Pat |

Yes, I noticed that weird lighting during the eclipse of 4 Dec 2002. |

I noticed that during the total eclipse that went through North Dakota in 1979. (I'd been waiting around for that one ever since I was a kid- I only had to drive around 150 miles to see it. Won't have another one in the state till 2044.) Pat |

Hi all
"Pat Flannery" wrote in message ... original post snipped That might make an interesting study- stick some volunteers into a reddish low light room for a few weeks and see if they have any unusual psychological responses. It's going to make a difference in color perception, particularly if their spacecraft uses Earth-type colored light inside. I was at a party once where the room was lit by a red neon fixture; on going outside the Moon appeared to be bright green. I might be misinformed here but don't military vessels switch to red light during combat situations to add the crew's night vision? Or is this a myth or no longer done, or what? If this is true what are the testimonies and results that can be gleaned from the people who have already worked (potentitally) hundreds of hours under these conditions? Pat If you are worried about people wanting to see a blue sky or green plants or what ever send along colour filters to stick over the winds and lots of pots and soil. Keep the crew busy while the Martian weather is being uncooperative, or while someone is restricted to light duties for health reasons. Regards Frank Scrooby |

They switch to red light at nightime wherever the crew might have to go outside, whether in combat or no. Going back and forth from the red-lit areas to regularly lit areas never seemed to pose a great problem for me, but I don't recall ever spending more than an hour or three on the conn when rigged for red. The control room of the submarine was rigged for red at night in case we needed to use the periscope. If we were actually using the periscope, we were rigged for black in the control room. (*No* area lighting and dimmers on important instrumentation turned down to the bottom stop. Unimportant instrumentation was simply turned off.) D. -- Touch-twice life. Eat. Drink.
