Say this quickly three times - magnetoplasmadynamic thruster!
NASA/JPL successfully tested a new magnetoplasmadynamic (MPD) ion thruster spacecraft engine that runs on lithium metal vapor.
Ion engines accelerate ions โ charged atoms โ out through a nozzle to provide thrust, hence they are often described as using "electric propulsion" and are 25 times more powerful that current engines that burn chemical propellant.
The test showed the electric propulsion system capable of operating at power levels up to 120 kilowatts. https://www.space.com/astronomy/mars/nasa-is-making-a-powerful-new-ion-engine-to-send-astronauts-to-mars-and-it-just-passed-its-1st-test #NASA #Space #SpaceCraft #MPDEngines #magnetoplasmadynamic #Ions #IonThruster #Lithium

Unlike the easily predictable #radiation โข๏ธ exposures from flying through the Van Allen Belts or basking in the background flux of #galactic ๐ cosmic rays, the dose an #astronaut gets from #solar โ๏ธ activity can vary enormously. Predicting #SpaceWeather remains a decidedly inexact ๐ฎ #science. High-energy #protons and #ions can tear through metal and flesh alike, damaging #DNA and other delicate cellular machinery. Typically, these showers are linked to #CME https://www.scientificamerican.com/article/space-weather-could-threaten-nasas-artemis-ii-astronauts-during-their-trip/

In ๐ 2023, #SpaceX launched the first of its #Starlink V2 Mini satellites ๐ฐ๏ธ. These next-generation spacecraft are equipped with #HallEffect thrusters, or #HETs, that operate on #argon, instead of the #krypton propellant on previous Starlinks https://aerospaceamerica.aiaa.org/year-in-review/a-year-of-firsts-for-electric-propulsion
The essential working principle of the #HallThruster is that it uses an #electrostatic potential to accelerate #ions up to high speeds https://en.wikipedia.org/wiki/Hall-effect_thruster#Principle_of_operation

"The #bromine in the #restoration #solution initiates spontaneous corrosion upon contact with the aluminum in the spent #battery. During this process, #electrons are released from the corroded aluminum and subsequently transferred to the spent #cathode material."
โTo maintain charge neutrality, #lithium #ions in the restoration solution are inserted into the cathode material. This recovery of lithium ions restores the cathode material to its #original state."
