In today's APOD, a beautiful Evening View showing the pink and light brown/orange Martian Sky over Ares Vallis, (almost) as it would be seen by a Human Observer that were on Mars, near the NASA - Mars Pathfinder Lander. This frame is an Extre Detail Magnification (EDM) taken from an Absolute Color Image-Mosaic that was obtained during thel 24th Sol of the NASA - Sojourner-Pathfinder Mission to Mars, at approximately 16:10 Mars Local Solar Time (Middle Afternoon). The two small Hills (nicknamed "Twin Peaks") that characterize the Ares Vallis Panorama that was visible from the NASA - Sojourner-Pathfinder's Landing Site, lie just on to the left side of the Horizon, but they are not visible here. The Sky near the setting Sun, as you can see, shows a pale blueish color while the Solar Disc appears slightly orange and yellow. It has to be said, however, that the color of the Sun itself, even after this Absolute Natural Colors processing (and just like the NASA People had already underlined after having used their "home-made" color processing), may not be completely accurate. The Natural Color of the Sun, in fact, should be - to a human eye - kind of white and (perhaps slightly) blueish. |
