Ricochets on Asteroids: Experimental study of low velocity grazing impacts into granular media
Esteban Wright, Alice Quillen, Juiliana South +6
Spin off events and impacts can eject boulders from an asteroid surface and rubble pile asteroids can accumulate from debris following a collision between large asteroids. These pr…
Boulder Stranding in Ejecta Launched by an Impact Generated Seismic Pulse
Esteban Wright, Alice C. Quillen, Juliana South +6
We consider how an impact generated seismic pulse affects the surface of an asteroid distant from the impact site. With laboratory experiments on dry polydisperse gravel mixtures,…
A Light-weight Vibrational Motor Powered Recoil Robot that Hops Rapidly Across Granular Media
Alice C. Quillen, Randal C. Nelson, Hesam Askari +3
A 1 cm coin vibrational motor fixed to the center of a 4 cm square foam platform moves rapidly across granular media (poppy seeds, millet, corn meal) at a speed of up to 30 cm/s, o…
Impact Excitation of a Seismic Pulse and Vibrational Normal Modes on Asteroid Bennu and Associated Slumping of Regolith
Alice C. Quillen, Yuhui Zhao, YuanYuan Chen +3
We consider an impact on an asteroid that is energetic enough to cause resurfacing by seismic reverberation and just below the catastrophic disruption threshold, assuming that seis…
