Witryna1 cze 2003 · Such an impact could simulate the impact of a strong, nickel-iron projectile into a very low density–high porosity comet or weak, porous asteroid. We expected beforehand that the impactor might perhaps simply burrow its way through the Styrofoam sphere and emerge out the other side, leaving the sphere more or less intact.
