Repeated Flybys Yield a Pole-to-Pole View of Europa
This view of Jupiter's moon Europa features several regional-resolution mosaics overlaid on a lower resolution global view for context. The regional views were obtained during several different flybys of the moon by NASA's Galileo mission.
These images compare surface features observed by NASA's Cassini spacecraft at the Xanadu region on Saturn's moon Titan (left), and features observed by NASA's Galileo spacecraft on Jupiter's cratered moon Callisto (right).
NASA's Galileo spacecraft captured this dramatic image of mountains on Io. The Sun was low in the sky. A low scarp runs from the upper left toward the center of the image. The jagged ridge is Mongibello Mons.
Reddish spots and shallow pits pepper the enigmatic ridged surface of Europa in this view combining information from images taken by NASA's Galileo spacecraft during two different orbits around Jupiter.
Asteroid Ida and its Satellite Dactyl in Enhanced Color
During its examination of the asteroid Ida, NASA's Galileo spacecraft returned images of a second object, Dactyl--the first confirmed satellite or moon of an asteroid; the much smaller moon is visible to the right of Ida.
Natural color view of Ganymede from NASA's Galileo spacecraft during its first encounter with the satellite. The dark areas are the older, more heavily cratered regions and the light areas are younger, tectonically deformed regions.
This picture shows the asteroids Ida (left) and Gaspra (right) to the same scale. These images were taken by NASA's Galileo spacecraft while enroute to Jupiter. Gaspra was imaged on October 29, 1991 at a range of 3,300 miles (5,300 km).
