[0002] In the future development of lunar resources, it is necessary to collect a certain amount of lunar soil in situ and add it to the lunar surface in situ processing plant or lunar surface laboratory. The lunar soil in situ processing plant can use the lunar soil to generate oxygen in situ through certain chemical processes to support life activities on the lunar surface or as a propellant for spacecraft to reduce the cost of human entry into deep space. The lunar soil in situ processing plant can also use lunar surface 3D printing technology to make functional structures for lunar surface construction. The lunar surface laboratory can use lunar soil as raw material for some biological experiments. The lunar surface in situ processing plant and lunar surface laboratory need to regularly obtain lunar soil from the outside world through the lunar soil filling device. The lunar surface in situ processing plant and lunar surface laboratory are also called lunar soil filling objects.
