arcs: First photograph of the sunset on Mars, May 19th, 2005 On May 19th, 2005, NASA’s Mars Exploration Rover Spirit captured this stunning view of the Sun sinking below the rim of Gusev crater on Mars. This image was taken around 6:07 in the evening of the rover’s 489th Martian day. This small panorama of the western sky was obtained using Pancam’s 750, 530 and 430-nanometer color filters. This filter combination generates false-color images that are similar to what a human would see. 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. This mosaic is yet another example from the rover of a beautiful Martian scene that also captures some important scientific information. Specifically, sunset and twilight images are occasionally acquired by the science team to determine how high into the atmosphere the Martian dust extends, and to look for dust or ice clouds. The long Martian twilight (compared to Earth’s) is caused by sunlight scattered around to the night side of the planet by abundant high altitude dust. Similar long twilights or extra-colorful sunrises and sunsets sometimes occur on Earth when tiny dust grains from powerful volcanic eruptions scatter light high in the atmosphere.
