Planning Implications Related to Sterilization-Sensitive Science Investigations Associated with Mars Sample Return (MSR)
Published 2023“…Sterilization-sensitive measurements include the abundances and oxidation-reduction (redox) states of redox-sensitive elements, and isotope abundances and ratios of most of them. All organic molecules, and most minerals and naturally occurring amorphous materials that formed under habitable conditions, contain at least one redox-sensitive element. …”

Towards Practical Fixed-Wing Aircraft with Electroaerodynamic Propulsion
Published 2023“…Electroaerodynamic (EAD) propulsion is a novel means of generating thrust via collisions between ions and neutral molecules. EAD thrusters have no moving parts, and are therefore almost silent; they may therefore be useful for aircraft propulsion in applications where silence is valuable. …”
