NASA just tested a powerful new thruster that could send humans to Mars

A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA’s Jet Propulsion Laboratory. Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached record-breaking power levels—far beyond anything currently used in space. Glowing hotter than molten lava and firing inside a specialized vacuum chamber, the thruster hints at a future where spacecraft could travel farther and more efficiently than ever before.
