Mars was once the home of several green-skinned, telepathic, shapeshifting beings known as Martians, with one such being traveling to Earth and posing under the guise of Secretary of Defense Calvin Swanwick.
By 1999, it was commonly claimed that humanity had better maps of Mars than it did of Earth's ocean floor.
