In my August article, “The Red Planet’s colorful past,” I cover man’s research of Mars and its use in popular culture from ancient times up to the first spacecraft mission to the planet in the 1960s.

For example, did you know a Capuchin monk claimed to have observed two martian moons in 1643 (nearly 235 years before the discovery of Phobos and Deimos)? Or that a prize for communication with extraterrestrial life in the 1900s excluded Mars because the sponsor figured such a task was too easy?Astronomy magazine subscribers can read the full article for free.
