SAMPLE COLLECTING METHOD AND SAMPLE COLLECTING SYSTEM
Provided is a sample collecting method for collecting a sample of soil at a predetermined depth by excavation on an extraterrestrial body or the earth. The method comprises forming a first borehole 70 that reaches a first depth from a land surface 69 by preliminary excavation of soil, the first depth being less than a predetermine sampling depth from the land surface 69; and forming a second borehole 73 that has a smaller opening than the first borehole and reaches a second depth from the land surface by further excavation of soil in the first borehole, the second depth being equal to or greater than the sampling depth, wherein, while forming the second borehole 73, part of soil present at the sampling depth in the second borehole 73 is transferred to the land surface 69 as a sample for analysis.
