Interesting Patents: NASA Patents New Method of Propulsion

NASA was issued a patent for a new method of propulsion this week. This method is for vacuum arc thrusters for spacecraft, and propulsion systems including the same. This vacuum arc thruster (VAT) involves using anode and a cathode producing a high voltage arc capable of creating plasma. This plasma is then focused and directed out of a nozzle to create thrust through the use of magnetic fields. The cathode of the device is consumed as fuel as the propulsion device operates.
