Callisto. Voyager 1 photograph of Callisto,the outermost and faintest of the four Galilean moons of Jupiter. In the right of the image is a giant impact basin. This is about 600 km in diameter and is surrounded by bright concentric rings that stretch over a thousand kilometres. The rings are thought to have been caused by deformation of the crust as a result of the shock wave associated with the giant impact. The crust is believed to be a mixture of ice and rocky material,peppered with thousands of impact craters. The picture was taken on March 6,1979,when the spacecraft was 350,000 km from Callisto. It shows features about 7 kilometres wide on the surface | |
