The Pathfinder spacecraft was equipped with a stereoscopic camera on a 360-degree rotating mount, with two lenses mounted several inches apart that allowed scientists to take both detailed zoomed-in images as well as three-dimensional panoramic views of Mars. Pathfinder saw, moreover, that the Red Planet’s sky looks kind of pinkish-yellowish-red from the surface, thanks to varying amounts of dust particles that are always present in the atmosphere. In all, Pathfinder took more than 16,500 digital photos.
