China successfully tests EmDrive technology
China has successfully tested the potentially revolutionary spacecraft technology EMDrive in its labs, Dr. Chen Yue, the Director of Commercial Satellite Technology for the China Academy of Space Technology (CAST), announced.
While traditional spacecraft engines produce thrust by expelling mass, EMDrive makes use of electricity to create thrust or movement. It was first developed by Roger Shawyer as a microwave cavity in the form of a truncated cone with one end larger than the other. Electromagnetic resonance is created when the narrow end is hit with microwaves striking the cavity walls.
China has plans to use EMDrive reactionless engine in its LM-5 heavy rocket and electrical satellite propulsion as part of its space program aimed at sending missions to Mars, Venus, Jupiter and asteroids.
Digital Trends wrote, “Reactionless drives are named as such because they lack the ‘reaction’ defined in Newton’s third law: ‘For every action there is an equal and opposite reaction.'”
While China has not yet released any images of its EMDrive engine, American space agency NASA has released photographs of a different EMDrive named Eagle.
EMDrive engines will be excellent to explore deep space as they will not need to be refueled.
