Io as shown in the 1984 film "2010: The Year We Make Contact".
In the book, Arthur C Clarke wrote:
"Io is Mordor: look up Part Three. There’s a passage about “rivers of molten rock that wound their way… until they cooled and lay like twisted dragon-shapes vomited from the tormented earth.” That’s a perfect description: how did Tolkien know, a quarter century before anyone ever saw a picture of Io? Talk about Nature imitating Art.'"
