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. Because Earth was too faint to be detected in images taken with the panoramic camera's color filters, the inset image shows a combination of four panoramic images zoomed in on Earth.
