Nicholson Regio and Arbela Sulcus, Ganymede This Galileo SSI mosaic covers the dark terrain of Nicholson Regio on Jupiter's moon, Ganymede. Near the center of the image is a crater that has been torn apart by tectonic forces. A lane of ridges and grooves (probably extensional fault blocks) cuts through the crater and distorts its originally circular shape. The pair of oblong craters to the right was formed by the impact of a gravitationally bound pair of asteroids or a split comet. The oblong shapes of the craters suggest that the impactors struck the surface at a shallow angle.
