Say good bye to cryogenic chilled propellant in your rocket!
Rocket Boffins@ NASA’s Jet Propulsion Laboratory recently fired up a magnetoplasmadynamic (MPD) thruster (aka "electric thruster") that runs on lithium metal vapor.
This prototype achieved power levels (120 kilowatts) beyond the highest-power electric thrusters on any of the agency’s current spacecraft.
Fully developed and paired with a nuclear power source, they could support payloads required for human Mars missions. https://www.jpl.nasa.gov/news/nasa-fires-up-powerful-lithium-fed-thruster-for-trips-to-mars/ #NASA #JPL #Princeton #ElectricPropulsion #Rockets #Space #Mars #Lithium #Thruster #RocketThruster #electromagnetic #magnetoplasmadynamic

Extended capability electric propulsion coming soon to a Satellite near you soon - thanks to China!
China successfully demonstrated a new 750-newton Hall-effect thruster (electric propulsion) surpassing the performance of all comparable preceding systems.
The engine powered Experiment Satellite 26A from its initial transfer orbit to geostationary orbit through five orbit-raising manoeuvres, firing for a cumulative 11,617 seconds (approximately 3.2 hours) during its maiden mission.
The engine, which was designed to run for nearly 10 hours, operated continuously for more than 14 hours during testing.
In contrast, the leading US-made R-42DM and Europe’s Leros-1B, are designed to operate for about seven hours. https://militarywatchmagazine.com/article/china-satellite-engine-new-global-record #Space #China #Satellite #ElectricPropulsion #ElecticEngine #Hall_Effect_Thrusters #EarthOrbit #SpaceCraft #GeostationaryOrbit

Electric foiling pilot boat.
Great use case for electric propulsion: Pilot boats are fast, short range and return to port regularly.
This one can be fast charged in 1 hour.

#ElectricPropulsion uses up to 90% less 📉 propellant than traditional, high-thrust chemical rockets. During tests, the #NASA JPL team achieved power levels of up to 120 kilowatts. That’s over 25 times 📈 the power of the thrusters on Psyche. The team aims to reach power levels between 500 kilowatts and 1 megawatt per thruster. A human 🧑🚀 mission to #Mars might need 2 to 4 megawatts of power, requiring multiple MPD thrusters https://www.jpl.nasa.gov/news/nasa-fires-up-powerful-lithium-fed-thruster-for-trips-to-mars/

Electric engines use much less fuel than chemical engines for long space trips. This means spacecraft can travel further without needing as much heavy fuel.

#GeneralGalactic’s water 💧 propulsion system could provide 5-10 times the Delta-V of traditional systems. For #chemical propulsion, it will use electrolysis to split water, then burn the hydrogen with oxygen as the oxidizer. For #electrical propulsion, it will split water and then apply sufficient electrical energy 🔋 to convert the oxygen into plasma. It will then use a #magnetic field to guide the plasma out of a thruster https://interestingengineering.com/space/satellite-using-water-powered-propulsion-system
