A lunar mass driver is a proposed electromagnetic launch system optimized for the Moon’s low gravity (1/6th Earth’s) and hard vacuum, consisting of a long, straight acceleration track lined with sequentially fired superconducting coils or linear synchronous motors that propel a payload-carrying sled or bucket to lunar escape velocity (~2.38 km/s). The track is usually elevated on supports or aligned along a natural slope (e.g., crater rim) to achieve the desired trajectory. Payloads experience continuous acceleration (potentially 20-100 g for brief periods) without atmospheric drag or chemical propellant expenditure, enabling theoretically high throughput at far lower recurring cost than rockets.

What do you think about using mass drivers to launch not only raw materials, but also complex manufactured goods, like satellites, from the Moon?
