"The prototype, a 'lithium-fed magnetoplasmadynamic (MPD) thruster,' generates thrust by using high currents to electromagnetically accelerate lithium plasma, or hot, ionized particles of the alkali metal."
"NASA officials heralded the latest test as an important step in the right direction as it prepares to send the first humans to Mars within the next ten years or so."
"'At NASA, we work on many things at once, and we haven't lost sight of Mars,' said NASA administrator Jared Isaacman in a statement."
NASA is investigating an electric propulsion system using a lithium-fed magnetoplasmadynamic thruster, which could significantly reduce the need for heavy propellants. A recent test at the Jet Propulsion Lab demonstrated the thruster's capabilities, achieving unprecedented power levels. The thruster generates thrust by electromagnetically accelerating lithium plasma. While electric thrusters have been used before, this specific type has not yet been tested in space. NASA officials view this test as a crucial advancement toward sending humans to Mars within the next decade.
