VIS-NIR reflectance spectra of 6 different particles size fractions of the Mars Global Simulant MGS-1 (CLASS Exolith Lab - UCF)

Six different particle size fractions of the Mars regolith simulant MGS-1 were separated by dry sieving with a Varisfiter sonic separator. Their respective VIS-NIR reflectance spectra were then measured with the MoHIS hyperspectral imager.采用Varisfiter声波筛分仪通过干法筛分（dry sieving），分离得到6种不同粒径级分的火星土壤模拟物MGS-1（Mars regolith simulant MGS-1）；随后利用MoHIS高光谱成像仪（hyperspectral imager），对各粒径级分的可见光-近红外（Visible-Near Infrared，VIS-NIR）反射光谱进行了测量。
