[YouTube] “I’m Dreaming of a Blue Sunseton Mars”: This Martian sunset, captured by NASA’s Mars Exploration Rover Opportunity on Nov. 4 and 5, 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.
