Flag of Mars Flag of Mars A flag of Mars is a flag or flag design that represents the planet Mars or that represents a fictional Martian government. Science fiction authors have, for literary purposes, described the flags of fictional Martian governments. Some of the readers of those flag descriptions have created flags or flag images that are based on the authors’ descriptions. Flag images for two fictional Martian governments are presented in this article. Advocates of the exploration and settlement of Mars have designed, manufactured, and sold Mars flags, sometimes with the hope that their designs may one day be adopted and

Since Phobos orbits Mars faster than the planet itself rotates, tidal forces are slowly but steadily decreasing its orbital radius. At some point in the future, when it approaches Mars closely enough (see Roche limit), Phobos will be broken up by these tidal forces. Several strings of craters on the Martian surface, inclined further from the equator the older they are, suggest that there may have been
