Lunar launches are basically all processed material and probes, and hence all
outgoing. There's no need for energy storage: at 1.4 kW/m^2 insolation during
lunar day energy is abundant.

10 t is a lot. The forces on the solenoids will be high. It makes more sense
to scale down the packet size (10-100 kg) and go into a rapid-fire
semicontinuous launch mode.

Things are easier on Luna. Curvature is higher, though, so longer rails will
take higher ramps.
