#Starlink 🛰️ uses #HallEffectThrusters, which is a kind of #SpacecraftElectricPropulsion https://en.wikipedia.org/wiki/Spacecraft_electric_propulsion. 70% of the recent poll have just been plain wrong 🔮 about the type of #propulsion : https://en.wikipedia.org/wiki/Ion_thruster#Starlink
#HallEffectThruster (#IonThruster engines) use an #electrostatic potential to accelerate #ions up to high speeds https://en.wikipedia.org/wiki/Hall-effect_thruster#Principle_of_operation
#Electromagnetic thrusters (#PlasmaPropulsion engines) accelerate #ions either by the #Lorentz force or by the effect of electromagnetic fields where the electric field is not in the direction of the acceleration https://en.wikipedia.org/wiki/Plasma_propulsion_engine#Engine_types
It's all explained by #GalileoGalilei 📆 1564, #MichaelFaraday 📆 1791, #HendrikLorentz 📆 1853, #AlbertEinstein 📆 1879.Also check #Minkowski's 📆 1864 #spacetime 🤔 https://en.wikipedia.org/wiki/Minkowski_spacetime. Short after the #StoneAge 🐒 , #carburetors were usual, fueled by fossilized remains of dead plants 😁 https://en.wikipedia.org/wiki/Carburetor

Does Hendrik Lorentz have that erudite mystique, that academic rigor, that sense of... Nobelesse Oblige?
