“Field Emission Electric Propulsion (FEEP) is a type of electric propulsion that uses electrostatic fields to extract and accelerate ions from a liquid metal propellant, producing thrust. It is known for its extremely precise thrust control, making it ideal for applications that require high-precision positioning in space.”
“Indium (In) is a soft, silvery-white metal with atomic number 49. It is commonly used in electronics, semiconductors, and coatings due to its excellent conductivity. Indium is non-toxic, nonreactive and nonradioactive, making it a safe and easy to handle.”
“FEEP thrusters can be used for precise spacecraft maneuvers, including station-keeping, orbit raising, formation flying, collision avoidance, and drag compensation. Their high precision and controllability make them ideal for missions requiring fine attitude adjustments.”
“Alpha (α) emitters provide the best balance between price, performance, and guaranteed delivery times. This is the perfect solution for commercial constellation applications.”
“Most electric propulsion systems operate at a fixed power point, so they are typically characterized by a single thrust and specific impulse value. FEEP thrusters are different. They operate across a wide power range, and as a result, both thrust and specific impulse vary with input power.”
