Fig. 4

Impact geometry – the projectile hits the surface of Mars (horizontal line) at velocity vi at an angle α. The snapshot shows the situation 75 s after the impact of a 5 km-diameter asteroid hitting the surface at vi = 7.5 km s-1 and α = 30°. The data shown is a cut along the plane spawned by the projectile’s velocity vector and a vector perpendicular to the planet’s surface.
