Ganymede - Voyager 2

Lagash Sulcus and other furrows and ridges on Ganymede

Voyager 2 image of Lagash Sulcus in Jupiter's moon Ganymede. The sinuous system of ridges and furrows running through the center of the image stretches for over 1400 km. Note the complex grid of linear features at the lower left. This image is referred to as "Ganymede City" in Arthur C. Clarke's book "3001". The image was taken from 112,000 km on 9 July 1979. The frame is 700 km across and north is at 11:30. (Voyager 2, FDS 20637.29)
