July 21, 1981 – Planet Saturn, along with moons Rhea and Dione, photographed by the Voyager 2 probe. The original caption from the 1982 NASA book Voyages to Saturn: “The rings of Saturn appeared much brighter to Voyager 2 than to Voyager 1 because of increasing solar illumination during the nine-month interval between encounters. On July 21, from a distance of 34 million kilometers, several prominent cloud features were already visible–evidence of increased activity in the atmosphere of Saturn, as well as of a more sensitive camera on the Voyager 2 spacecraft.“ (NASA)
