Sunset on Mars: the first color photograph

Four shots were taken within 6 minutes 51 seconds. This is the first sunset that the Curiosity color camera has observed - the photos only adjusted the white balance for better clarity.

The dust in the atmosphere of Mars is very fine, which allows the light of the blue spectrum to pass through the atmosphere more efficiently than light with a different wavelength. This feature of the Martian atmosphere is more noticeable at the beginning and end of the day, and blue light is better visible next to the Sun.
