, Robert A. Heinlein describes a future lunar settlement where future lunar residents send payloads of wheat and water ice to Earth using an electromagnetic catapult. In this story, a group of Loonies conspire to take control of this catapult and threaten to “throw rocks at Earth” unless they recognize Luna as an independent world. Interestingly enough, scientists have explored this concept for decades as a means of transferring lunar resources to Earth someday.
After accelerating for ten minutes, the arm would achieve the Moon’s escape velocity of 2.4 km/second and release the payload on a trajectory toward Earth. The team also emphasizes that the main payload would be helium-3 harvested from lunar soil, which could be used to power fusion reactors on Earth. “The system’s technical readiness is relatively high,” they wrote.
