Aliens
In H. G. Wells’ War of the Worlds, and many novels since, Mars has been assumed to be the home of alien life forms, many of them bent on conquest of Earth. In actual fact, the best we’ve found is what looked like a tiny bacterium in a meteorite which actually wasn’t.

Mars was the god of war in the Roman pantheon, oustripping Ares, the Greek version, with a selection of exciting new features and an entirely redesigned user interface.
The music
Mars, Bringer of War is a tune in Holst’s Planets suite.

Mars bars are an ubiquitous commodity, comprising a milk chocolate outer coating with a caramel and nougat centre.
