Some other method of shock absorbtion or thrust against Martian gravity must be added. | |

Much as NASA plans to when it send its first mission to Mars. These will be big relatively dumb supply boxes sent on a trajectory to reach mars, they will then be brought into orbit and then sent into a degradation orbit until they reach atmosphere. At this point they will fall and parachutes will catch them, much as the satellite that landed the mars rover did. | |
