Duration is scaled by thermal diffusion (*6) time. The colors indicate different projectiles and impact speeds: PC is a polycarbonate sphere with a diameter of 4.7mm and Al is an aluminum sphere with a diameter of 2mm.
A research group from Kobe University has demonstrated that the heat generated by the impact of a small astronomical body could enable aqueous alteration (*1) and organic solid formation to occur on the surface of an asteroid. They achieved this by first conducting high-velocity impact cratering experiments using an asteroid-like target material and measuring the post-impact heat distribution around the resulting crater...
