Abstract

<p>Elucidation of the Moon and Mars environment is important for humans in pursuing space exploration. Moon and Mars exploration plans have previously existed, primarily adopting an excavation method using drills and scoops for soil sample collection mechanisms. Luna 16 (1970) excavated lunar soil using a drill and was the first unmanned mission to return it to Earth, and rovers Curiosity and Opportunity collected Mars soil using drills and scoops and analyzed it on-site. However, as this method is executed with mechanical remote control, its demerits include the requirement of accurate control, high malfunction risks, and the existence of many complex mechanical driving parts. We developed a particle sampling system using magnetic force since its control and mechanism are simpler, it is more reliable, and lunar and Mars soil are magnetic. High possibility of implementation is expected with the existence of past papers on flight phenomenon of magnetic particles due to magnetic force, and research plans of particle transportation on the Moon. Furthermore, we believe that our mechanism can be implemented as particle transportation device for ISRU (In-Situ Resource Utilization), which supposes future long-term manned missions to the Moon to generate water and oxygen from lunar regolith. This paper investigates the development of a multi-layer magnetic sampling and transportation system using multiple electromagnetic coils, which expects usage in space environment and long-distance transportation. We evaluated the system performance through 1-m length magnetic particle transportation experiments and particle behavior analysis using numerical calculations.</p>
