Processing steps
Step Chronology Date Type Process Changes
#1 before layer formation mixing The ice particles and the mineral powder are blended together with the help of a vortex mixer while they are repeatedly plunged into liquid nitrogen to avoid the sublimation and metamorphism of ice during the process. Ice and dust particles are mixed at the particles scale.
#2 during layer formation layer formation Because porosity influences the reflectance of the samples, we filled the sample holders without compressing the samples: the sample holders are first overfilled and then the excess is removed with a spatula. In this way, we obtain non-compacted samples with flat surfaces. We obtain a non-compacted sample with a flat surface.
