Numerical modeling of lander interaction with a low-gravity asteroid regolith surface
Context. The JAXA asteroid sample return mission Hayabusa2 reached its target (162173) Ryugu in June 2018 and released the European (CNES-DLR) lander MASCOT in October 2018. MASCOT successfully
Scaling and dynamics of sphere and disk impact into granular media.
These findings are discussed in the context of recently proposed phenomenological models that capture qualitative dynamical features of impact but fail both quantitatively and in their inability to capture significant acceleration fluctuations that occur during penetration and which depend on the impacted material.
Microstructure evolution during impact on granular matter.
We study the impact of an intruder on a dense granular material. The process of impact and interaction between the intruder and the granular particles is modeled using discrete element simulations in
Regolith behavior under asteroid-level gravity conditions: low-velocity impact experiments
AbstractThe dusty regolith covering the surfaces of asteroids and planetary satellites differs in size, shape, and composition from terrestrial soil particles and is subject to environmental
Utilizing the Explicit Finite Element Method for Studying Granular Flows
Granular flows are systems of complex dry particulates whose behavior is difficult to predict during sliding contact. Existing computational tools used to simulate granular flows are particle
