Blue Martian Sunset Lumbar Pillow

Sunset on Mars as photographed by NASA's Curiosity rover. Sundown in Gale Crater on the 956th day, or sol (April 15, 2015), of the Curiosity mission. Customizable text reading "SUNSET AT GALE CRATER, APRIL 15, 2015" also appears. Add your own additional text on the reverse side. When the photograph was taken there was much very fine dust in the atmosphere. Normal daylight conditions enhance the reddish, rusty colour of the dust. However, light conditions at sunset make the sky look more blue. Image credit: NASA/JPL-Caltech/MSSS/Texas A&M University.
