摘要

This paper presents and assesses several strategies and technologies for the exploration of a lunar polar crater. The overall scenario is based on the precision landing of a spacecraft on top of a polar peak of eternal light in the vicinity of the crater. Three new technical systems have been conceptualised and are compared to three existent systems. A first exploration concept comprises a rocket-propelled harpoon, which performs a flight trajectory into the crater. After the touchdown, the harpoon system releases a small wheeled vehicle. By re-winding its tethered connection with to the lander spacecraft, it drives backwards and performs in-situ analyses. The second exploration concept is based on robust measuring projectiles that are ejected from the landing vehicle into the crater by an explosive ordnance system. They remain in their impact position and transmit their spectroscopic measurement data through telemetry. The third system comprises an autonomous flying vehicle, which performs multiple parabolic flights into the crater. The further three existent technical systems rely on rovers that autonomously enter the crater. As locomotion means they rely on legged, wheeled and tracked propulsion. All systems have been assessed against a number of evaluation criteria for the optimum solution by a cost-utility-analysis.
