The powerful new engine may one day help astronauts travel deeper into space using far less fuel than traditional rockets. Credit: NASA\/JPL-Caltech<\/p>\n<p><strong>NASA just tested a blazing-hot plasma engine that could help carry humans to Mars.<\/strong><\/p>\n<p>NASA\u2019s experimental lithium-powered plasma thruster has cleared a major early test, marking another step toward future human missions to Mars. Engineers at NASA\u2019s Jet Propulsion Laboratory (JPL) in Southern California recently fired the electromagnetic engine at power levels never before achieved in the United States for this type of propulsion system.<\/p>\n<p>The test took place on February 24 inside a specialized vacuum chamber at JPL designed for high-power electric propulsion research. During the experiment, the prototype engine operated at levels beyond those reached by any electric thruster currently flying on NASA spacecraft. Researchers say the results will guide the next phase of development and testing.<\/p>\n<p>\u201cAt NASA, we work on many things at once, and we haven\u2019t lost sight of Mars. The successful performance of our thruster in this test demonstrates real progress toward sending an American astronaut to set foot on the Red Planet,\u201d said NASA Administrator Jared Isaacman. \u201cThis marks the first time in the United States that an electric propulsion system has operated at power levels this high, reaching up to 120 kilowatts. We will continue to make strategic investments that will propel that next giant leap.\u201d<\/p>\n<\/p>\n<p>Record-Breaking Plasma Thruster Test<\/p>\n<p>The engine uses lithium metal vapor and belongs to a class of technology known as magnetoplasmadynamic (MPD) thrusters. These systems create thrust by using electric currents and magnetic fields to accelerate plasma at extremely high speeds.<\/p>\n<p>During five separate ignitions, the thruster\u2019s tungsten electrode glowed brilliant white as temperatures climbed above 5,000 degrees Fahrenheit (2,800 degrees Celsius). The tests were conducted in JPL\u2019s Electric Propulsion Lab, which houses a unique facility capable of safely evaluating electric thrusters that rely on metal vapor propellants at megawatt-class power levels.<\/p>\n<p><a href=\"https:\/\/scitechdaily.com\/images\/James-Polk-CoMeT-Vacuum-Facility.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-519235\" src=\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2026\/05\/James-Polk-CoMeT-Vacuum-Facility-777x437.jpg\" alt=\"James Polk CoMeT Vacuum Facility\" width=\"777\" height=\"437\"  \/><\/a>JPL senior research scientist James Polk peers into the condensable metal propellant (CoMeT) vacuum facility at JPL\u2019s Electric Propulsion Lab, where a high-power electric thruster prototype his team developed was being put to the test in February 2026. Credit: NASA\/JPL-CaltechWhy Electric Propulsion Matters for Mars<\/p>\n<p>Electric propulsion systems are far more fuel efficient than conventional chemical rockets, using up to 90% less propellant. Instead of delivering short bursts of powerful thrust, they provide a gentle but continuous push that steadily accelerates spacecraft over long periods.<\/p>\n<p>NASA already uses electric propulsion on missions such as Psyche, which currently operates the agency\u2019s highest-power electric thrusters. Over time, Psyche\u2019s propulsion system can accelerate the spacecraft to speeds of 124,000 mph.<\/p>\n<p>The new lithium-fed MPD thruster could eventually deliver much greater thrust than existing systems. Although scientists have researched MPD propulsion since the 1960s, the technology has never been used operationally in space.<\/p>\n<p>In the recent JPL test, the engine reached 120 kilowatts of power, more than 25 times greater than the thrusters flying on Psyche.<\/p>\n<p>\u201cDesigning and building these thrusters over the last couple of years has been a long lead-up to this first test,\u201d said James Polk, senior research scientist at JPL. \u201cIt\u2019s a huge moment for us because we not only showed the thruster works, but we also hit the power levels we were targeting. And we know we have a good testbed to begin addressing the challenges to scaling up.\u201d<\/p>\n<p><a href=\"https:\/\/scitechdaily.com\/images\/Prototype-Thruster-CoMeT-Vacuum-Facility.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-519234\" src=\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2026\/05\/Prototype-Thruster-CoMeT-Vacuum-Facility-777x437.jpg\" alt=\"Prototype Thruster CoMeT Vacuum Facility\" width=\"777\" height=\"437\"  \/><\/a>The prototype thruster is enclosed in JPL\u2019s condensable metal propellant (CoMeT) vacuum facility, a unique national asset designed to safely test thrusters using metal-vapor propellants as part of potential megawatt-class electric propulsion systems.

When the thruster activated, its nozzle-shaped outer electrode glowed intensely while producing a vivid red plasma plume.<\/p>\n<p>Polk has spent decades working on electric propulsion technologies and previously contributed to NASA\u2019s Dawn mission and Deep Space 1, the first spacecraft to demonstrate electric propulsion beyond Earth orbit.<\/p>\n<p>Scaling Up for Human Missions to Mars<\/p>\n<p>Researchers hope to eventually increase each thruster\u2019s power output to between 500 kilowatts and 1 megawatt. One of the biggest technical hurdles will be ensuring the hardware can survive prolonged operation at extreme temperatures.<\/p>\n<p>A crewed mission to Mars could require between 2 and 4 megawatts of total power, meaning several MPD thrusters would likely need to operate continuously for more than 23,000 hours.<\/p>\n<p>Scientists believe lithium-fed MPD engines could play an important role in future deep-space exploration because they combine strong thrust with efficient propellant use. Paired with nuclear power systems, they could reduce launch mass while carrying the heavy payloads needed for human Mars missions.<\/p>\n<p>NASA\u2019s Nuclear Electric Propulsion Program<\/p>\n<p>The MPD thruster project has been under development for the past 2\u00bd years through a collaboration between JPL, Princeton University in New Jersey, and NASA\u2019s Glenn Research Center in Cleveland. Funding comes from NASA\u2019s Space Nuclear Propulsion project, which began in 2020 to support the development of megawatt-class nuclear electric propulsion systems for future Mars missions. The effort is managed through NASA\u2019s Marshall Space Flight Center in Huntsville, Alabama, as part of the agency\u2019s Space Technology Mission Directorate.<\/p>\n<p><b>Never miss a breakthrough: <a href=\"https:\/\/scitechdaily.com\/newsletter\/\" rel=\"nofollow noopener\" target=\"_blank\">Join the SciTechDaily newsletter.<\/a><\/b><br \/><b>Follow us on <a href=\"https:\/\/www.google.com\/preferences\/source?q=scitechdaily.com\" rel=\"nofollow noopener\" target=\"_blank\">Google<\/a> and <a href=\"https:\/\/news.google.com\/publications\/CAAqLAgKIiZDQklTRmdnTWFoSUtFSE5qYVhSbFkyaGtZV2xzZVM1amIyMG9BQVAB?hl=en-US&amp;gl=US&amp;ceid=US%3Aen\" rel=\"nofollow noopener\" target=\"_blank\">Google News<\/a>.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"NASA has fired up a record-breaking lithium plasma thruster that could transform future missions to Mars.
