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 — charged atoms — 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 ☢️ exposures from flying through the Van Allen Belts or basking in the background flux of #galactic 🌌 cosmic rays, the dose an #astronaut gets from #solar ☀️ activity can vary enormously. Predicting #SpaceWeather remains a decidedly inexact 🔮 #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/

Space weather could threaten NASA’s Artemis II astronauts during their trip to the moon

A major solar storm during the Artemis II mission could harm astronauts. Here’s how NASA is protecting them

⚡By engineering lubricated interfaces inside #nanopores, researchers in the @EPFL Laboratory for Nanoscale Biology have enabled #ions to flow through a #nanofluidic membrane with unprecedented speed and control. In addition to enhancing nanofluidic technologies, the innovation could help accelerate the development of next-generation osmotic #energy harvesting. 📖 Read our news about this study, now published in Nature Energy 🔗 https://actu.epfl.ch/news/slippery-ions-create-a-smoother-path-to-blue-energ/

New study reveals solar flare ions are far hotter than expected, reaching temperatures over 60 million Kelvin

A new study by researchers from the University of St Andrews led by Alexander Russell has provided a groundbreaking explanation for a long-standing mystery about solar flares. For decades, scientists have known that solar flare plasma gets incredibly hot, but how ions and electrons heat up different... [More info]
