Blue Skies
Featured on May 14, 2015
The Curiosity rover recorded this Martian sunset on April 15. Particles of dust in the atmosphere absorb red wavelengths of light, allowing the bluer wavelengths to shine through. The effect is particularly prevalent at sunrise and sunset, when the sunlight must pass through a thicker layer of air. The Sun is setting behind the rim of Gale Crater, which Curiosity has been exploring for more than two years. Click on the image to see an animated version. [ NASA/JPL/Caltech/MSSS/Texas A&M]
