It's certainly incredible. One of a kind. We have several pictures of human-made objects on other planets (that is, Mars) – some of the Sojourner rover (nice to have a photographed now-landmark named after Sojourner Truth on Mars), the landers of previous rovers including the Challenger Memorial Station, and a selfie that should probably count, but that's the first and only one showing an actual landing on another planet, the only photograph of an airborne man-made object on Mars (hope we get photos of the helicopter), and the first external photograph of a large-scale rover (hope the helicopter gets us proper photos from a proper angle of the rover too). It's probably the most unusual thing in a photo after the Titan surface photo, and the most inspirational after the early photographs of the outer solar system, including Neptune and Triton. Hope Elon Musk changes that with his Mars/BFR effort, before he powers up the death ray and kills us all that is. The robots may beat him to it, though.
