On the upper left image, the satellite is placed on an orbit relatively far from the Earth (± 36 000 km). This is why it is possible to see the "whole" planet.

On this figure, the satellite orbit is much closer to the Earth (± 800 km). Each square (black and red) represents one image. When several images are joined to each other to form a bigger image, scientists talk about a 'mosaic' being created.
