Could This Powerful New Fusion Rocket Thruster Propel Us Beyond Mars

Long-time Slashdot reader schwit1 shared this article from Sky.com:Dr. Fatima Ebrahimi "has invented a new fusion rocket thruster concept which could power humans to Mars and beyond," writes Sky.com Long-time Slashdot reader schwit1 shared their report:The physicist who works for the U.S. Department of Energy's Princeton Plasma Physics Laboratory designed the rocket which will use magnetic fields to shoot plasma particleselectrically charged gasinto the vacuum of space. According to Newton's second and third laws of motion, the conservation of momentum would mean the rocket was propelled forwardsand at speeds 10 times faster than comparable devices. While current space-proven plasma propulsion engines use electric fields to propel the particles, the new rocket design would accelerate them using magnetic reconnection... Dr. Ebrahimi's new concept performs much better than existing plasma thrusters in computer simulationsgenerating exhaust with velocities of hundreds of kilometres per second, 10 times faster than those of other thrusters. That faster velocity at the beginning of a spacecraft's journey could bring the outer planets within reach of astronauts, the physicist said.... "The next step is building a prototype!"Read more of this story at Slashdot.
