Satellite Pictures

How the Satellite Picture Is Made

The satellite sees this picture, and divides it up into little squares...
...sort of like this (but this is exaggerated). For each square it assigns a number which corresponds to the brightness of each square in the image.

The satellite sends all the numbers by radio to scientists back on Earth.

The scientists use the numbers sent back by the satellite to determine the brightness of each square in the picture and put the picture together.
