Subsurface pulse, crater and ejecta asymmetry from oblique impacts into granular media

Bingcheng Suo, A. C. Quillen, Max Neiderbach +9

We carry out experiments of 104 m/s velocity oblique impacts into a granular medium (sand). Impact craters have nearly round rims even at a grazing angle of about , howev…

Froude number scaling unifies impact trajectories into granular media across gravitational conditions

Peter M. Miklavcic, Ethan Tokar, Esteban Wright +4

The interactions of solid objects with granular media is countered by a resistance force that stems from frictional forces between the grains and the media's resistance to inertia…

Effects of reduced gravity on the granular fluid-solid transition: underexplored forces can dominate soft matter behaviors

Paul Sánchez, Karen E. Daniels, Heinrich Jaeger +1

Granular media are soft matter systems that exhibit some of the extreme behavior of complex fluids. Understanding of the natural formation of planetary bodies, landing on and explo…

Ejecta from the DART-produced active asteroid Dimorphos

Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61

Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…

After DART: Using the first full-scale test of a kinetic impactor to inform a future planetary defense mission

Thomas S. Statler, Sabina D. Raducan, Olivier S. Barnouin +38

NASA's Double Asteroid Redirection Test (DART) is the first full-scale test of an asteroid deflection technology. Results from the hypervelocity kinetic impact and Earth-based obse…

Transmission of a Seismic Wave generated by impacts on Granular Asteroids

Paul Sánchez, Daniel J. Scheeres, Alice C. Quillen

In this paper we use a Soft-Sphere Discrete Element method code to simulate the transmission and study the attenuation of a seismic wave. Then, we apply our findings to the differe…
