It was believed that running more #propellant through a Hall #thruster would wreck its efficiency, but new experiments suggest they might power a crewed #mission to #Mars

@steyrshrek you maybe find the #propellant experts at the #talk page of this article https://en.wikipedia.org/wiki/Colonization_of_Mars#Equipment_needed_for_colonization

#Nature 📆 10 November 2022 #Electric #propulsion : The gaseous #propellant is priorly #ionized and the charged #particles in the #plasmas are energized and #accelerated by applying #electromagnetic fields. #Electric #power obtained by #solar panels is converted into the #kinetic #energy of the propellant. A 30% conversion #efficiency is the highest to date https://www.nature.com/articles/s41598-022-22789-7
