A Penetrating-Anchoring Mathematical Model for the Soft Asteroid Anchoring System

The asteroid landing mechanism is necessary to be anchored to avoid flowing away. At present, the study on the anchoring system is mainly focused on the mechanical design, but there are few researches on the penetrating or anchoring mathematical model, and the researches on combining two models with...
