On May 19th, 2005, NASA's Mars Exploration Rover Spirit captured this view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th martian day, or sol. The filter combination allows false color images to be generated that are similar to what a human would see, but with the colors slightly exaggerated. Because Mars is farther from the Sun than the Earth is, the Sun appears only about two-thirds the size that it appears in a sunset seen from the Earth.
