NASA released an image of the earth and the moon in one picture, as seen from Mars. It was taken by the HiRISE Instrument on October 3rd, 2007.
On the Earth image we can make out the west coast outline of South America at lower right, although the clouds are the dominant features. These clouds are so bright, compared with the Moon, that they are saturated in the HiRISE images. In fact, the RED-filter image was almost completely saturated, the blue-green image had significant saturation, and the brightest clouds were saturated in the IR image. This color image required a fair amount of processing to make a nice-looking release.
“Nice-looking” is an understatement. http://hirise.lpl.arizona.edu/earthmoon.php -via Bad Astronomy Blog
