Here is an image of the Earth from Mars, this is something you definitely can't do from earth's surface. I wonder what mythology the Martians spawned with two morning stars (Venus and Earth).
This is the first image ever taken of Earth from the surface of a planet beyond the Moon. It was taken by the Mars Exploration Rover Spirit one hour before sunrise on the 63rd martian day, or sol, of its mission. The image is a mosaic of images taken by the rover's navigation camera showing a broad view of the sky, and an image taken by the rover's panoramic camera of Earth. The contrast in the panoramic camera image was increased two times to make Earth easier to see. 
Here is a movie of both of Mars' moons Phobos and Deimos streaming across the Martian sky with the constellation Sagittarius in the background. Phobos is the brighter one.
NASA's Mars Exploration Rover Spirit has cameras that can observe the heavens from the surface of Mars. See the enthusiasm of planetary scientist Jim Bell of Cornell University, Ithaca, N.Y., lead scientist for the panoramic cameras on Spirit and Opportunity, "It is incredibly cool to be running an observatory on another planet."Yet we seem so tiny and insignificant
