Moonbus
|
A moonbus is a small, light-duty VTOL (vertical take-off and landing) spaceship designed primarily for short-range low-altitude point-to-point ferrying of people and supplies on a moon. A moonbus "flies" over terrain by regulating downward thrusters to counter the moon's gravity while using horizontal thrusters or angling downward thrust to move over the moon's surface. Currently no practical moonbuses exist for lack of applicability. The first specific depiction of a moonbus appeared in the science fiction movie 2001: A Space Odyssey (Kubrick, 1968).
