New concept for rocket thruster exploits the mechanism behind solar flares

Science Daily  January 28, 2021 Current plasma thrusters that use electric fields to propel the particles can only produce low specific impulse. The device proposed by researchers at Princeton Plasma Physics Laboratory would apply magnetic fields to cause particles of plasma to shoot out of a rocket and propel the craft forward. The particles are accelerated using magnetic reconnection which also occurs in tokamaks. They showed that the new plasma thruster concept can generate exhaust with velocities of hundreds of kilometers per second, 10 times faster than those of other thrusters. According to the researchers the new concept provides the […]
