In response to a bunch of fake images from Curiosity going around Tumblr, I’ve assembled a little post explaining where various photographs actually came from.
Row 1: Fake. The first picture is an image from Mars (see below) with the Tatooine sunset from Star Wars photoshopped over it. The second is a CGI image made with some astronomy software, supposedly showing what Earth, Venus, and Jupiter would look like from Mars.
Row 2: Real, but not from Curiosity. The images are courtesy of the last two Mars Exploration Rover twins, Spirit (who photographed the sunset) and Opportunity (who photographed the footprints).
Row 3: Actual images from Curiosity.
