A Blue Sunset on Mars

Please accept marketing-cookies to watch this video.

This Martian sunset, captured by NASA's Mars Exploration Rover Opportunity on 4 and 5 November 2010, appears bluish. The panoramic camera movie combines exposures taken through different camera filters and accelerates about 17 minutes of sunset into a 30-second simulation. This clip is the longest sunset movie from Mars ever produced, taking advantage of adequate solar energy currently available to Opportunity.
