Mars cargo capsule. Computer artwork of an automated cargo capsule (lower right) beginning its one-way journey from a Mars cycler (upper left) to the surface of Mars (upper right). Cyclers are hypothetical spacecraft that are potentially useful for transporting people or materials using little propellant. Instead, they rely on gravity assist manoeuvres to keep them going.
