||The ever-increasing computational power of computers coupled with the need for advanced numerical techniques to simulate complex materials behavior in difficult to reproduce environments, gave momentum to the application of Discrete Element Method (DEM) in different industries. Space missions, in particular, face challenging conditions that require in-depth analysis and understanding. There has recently been a remarkable interest in DEM to predict the dynamics of the continuum and particulate materials in space missions. This symposium targets the application of discrete numerical methods in space missions. Topics such as soil behavior on asteroids and planets, boulder extraction in near-earth asteroids, and hypervelocity impacts to space vehicles are covered.
