Kinetic Hammer

From the moon (which has no air resistance and less gravity) we can build a launch platform with a "kinetic hammer" that transfers the energy stored from the platform to the spacecraft launching it into space. This will not only save precious fuel, but the source of this energy can be stored solar energy that drives a magnetic rail where a heavy object strikes the ship. This would allow us to send many of these ships into mars to help colonize the planet.
The ship itself is loaded with color-coded sections for different resources and can be powered by more conventional rocket systems (fuel is stored in the middle section of the ship).

This mini scale prototype shows how this system might work.
