"Plasma Interactions with Lunar Regolith/Dust"

We are very excited to be hosting another “cross talk”! The majority of our time has been spent focusing on the individual environmental elements, but this meeting will focus on plasma interactions with lunar regolith/dust. In an attempt to really dig into this topic, our 4-member panel will cover the following:

     Christoffersen, NASA Johnson Space CenterRegolith Properties

     Christine Hartzell, University of Maryland – Dust/Plasma Interactions

     Jean-Charles Mateo-Velez, ONERA - Modeling Efforts

     Paul Mackey, NASA Kennedy Space Center - Testing and The Electrodynamic Dust Shield (EDS)

 

Please see bios below and please feel free to post you questions in advance to this event below in the comments section.

Christoffersen, NASA Johnson Space Center,  has sixteen years research experience in space and planetary science encompassing early solar system and lunar surface materials and processes along with thirty years of experience in application of all aspects of transmission electron microscopy (TEM) to solid state processes in earth, space and materials science. 

Christine Hartzell is an Associate Professor in the Department of Aerospace Engineering at the University of Maryland. Her research focuses on the behavior of grains dominated by non-gravitational forces, with an emphasis on the evolution of airless planetary bodies and design of spacecraft.  She is a Participating Scientist on the OSIRIS-REx mission and the Mission Scientist on the Janus mission. Asteroid 9319 was named “Hartzell” in recognition of her contributions to the field of asteroid science. Prior joining the faculty at UMD, Dr. Hartzell was a Keck Institute for Space Studies Postdoctoral Fellow at Caltech. She completed her PhD in Aerospace Engineering at the University of Colorado at Boulder and received her B.S. in Aerospace Engineering from Georgia Tech. 

Jean-Charles Matéo-Vélez, Research Engineer at ONERA The French Aerospace Lab, is specialized in the fields of spacecraft charging and electrostatic discharges. He is in charge of modelling spacecraft plasma interactions, both numerically and experimentally, and is involved in mitigation techniques. He also conducts R&D activities related to lunar dust charging and adhesion.

Paul Mackey is a researcher with the Electrostatics & Surface Physics Lab at NASA Kennedy Space Center. He has a background in computer engineering and physics which he used to design ground support and space flight hardware for over 30 years. He was the technical lead of the Electrodynamic Dust Shield (EDS) flight project deployed on the International Space Station in 2019. He retired from NASA and now works for The Bionetics Corporation supporting the Electrostatics & Surface Physics Lab to demonstrate the Electrodynamic Dust Shield in the lunar environment.
