The images in this colour composite were acquired on 13 December 1990, when Mars was 85 million kilometres from Earth. This was two and one half weeks after opposition, when the angular size of Mars was about two thirds of its maximum at the best oppositions. The north pole is located near the center of the bright bluish clouds at the top of the image.
