Effect of regolith cohesive strength on simulated sampling encounters, modeled on the OSIRIS-REx mission. Weak regolith only offers weak resistance to the slow speed impact, while stronger regolith effectively stops penetration at the surface. The top figures show the configuration at impact, while the bottom figures show the maximum penetration. Simulation details and models are defined and discussed in Bierhaus et al. (2018)
