Mass of ejecta with velocities > υ for four individual micro-impact events, and the impact velocity is always 15 km/s. The two red lines show impacts on perlite–sand mixture (PS) with high porosity (ϕ = 0.6), and the black lines show impacts on rock. Spherical impactors with diameters of 100 µm and 200 µm are shown as solid and dashed lines, respectively.
