The Solid State Imager (SSI) on NASA's Galileo spacecraft acquired more than 500 images of Jupiter's moon, Europa, providing the only moderate- to high-resolution images of the moon's surface. Images were acquired as observation sequences during each orbit that targeted the moon. Each of these observation sequences consists of between 1 and 19 images acquired close in time, that typically overlap, have consistent illumination and similar pixel scale. The observations vary from relatively low-resolution hemispherical imaging, to high-resolution targeted images that cover a small portion of the surface. Here we provide average mosaics of each of the individual observation sequences acquired by the Galileo spacecraft. These observation mosaics were constructed from a set of 481 Galileo images that were photogrammetrically controlled globally (along with 221 Voyager 1 and 2 images) to improve their relative locations on Europa's surface. The 92 observation mosaics provide users with nearly the entire Galileo Europa imaging dataset at its native resolution and with improved relative image locations.
