Oh, and one final thing on Earth transits. Arthur C. Clarke wrote a story about a marooned astronaut on Mars watching a transit of Earth across the sun. Problem was, he wrote the story in 1971...and the transit in question occurred in 1984.

Since the color of martian sky was discussed early in this thread :
http://photojournal.jpl.nasa.gov/catalog/PIA07930 "Here is the martian twilight sky at Gusev crater, as imaged by the panoramic camera on NASA's Mars Exploration Rover Spirit around 6:20 in the evening of the rover's 464th martian day, or sol (April 23, 2005)." "...This small panorama of the western sky was obtained using camera's 750-nanometer, 530-nanometer and 430-nanometer color filters. This filter combination allows false color images to be generated that are similar to what a human would see, but with the colors exaggerated. In this image, the bluish glow in the sky above where the Sun had just set would be visible to us if we were there, but the redness of the sky farther from the sunset is exaggerated compared to the daytime colors of the martian sky...." |

Wooow, fantastic!
It shows exactly the blue sky around the sun. To me it looks like using somewhat excessive colors, though it's wonderful. It seems recently on sol476 and sol480 was a new "sun in the west" campaign. Following a L456 raw picture shows Gusev's west rim near THE crater as sharp as never before: http://www.greuti.ch/spirit/spirit_sol480_panL456.jpg -------------------- |

Did you use this in that image?
http://qt.exploratorium.edu/mars/spirit/pa...B2P2681L5M1.JPG According to the timestamp it was taken after sunset http://qt.exploratorium.edu/mars/spirit/pa...B2P2689L6M1.JPG perhaps thats why the Gusev's rim is so sharp. |

Yes these pics are from sol480. It's that was I've assumed for such a sharper view of this rim, that sun must been behind the rim at least. -------------------- |
