No one has ever seen a transit of Earth from Mars, but in 1971 Arthur C. Clarke published a science fiction story called "Transit of Earth," in which a doomed astronaut on Mars does in fact observe the 1984 transit. Needless to say, the story was rather optimistic about the pace of human exploration of the solar system.
The next transit of Earth from Mars will occur on November 10, 2084. Buy your tickets now!
