Expert Insights & Support To Ensure Mission Success

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.

Key Differences between FEEP and electrospray are:

Key Differences between FEEP and HET are:

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.

Gamma (γ) emitters are hand-picked for their guaranteed peak performance and are especially appropriate for your missions in deep space, exploration, and others where emitter output needs to be taken to extremes

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.

Yes, our products are classified as "dual-use" items and as such are subject to dual-use export controls. Therefore, depending on the end-use and country of destination, an export license may be required. Deliveries within the European Union and the United States generally do not require an export license.

ENPULSION offers some of the fastest lead times in the satellite propulsion industry. Our standard delivery times vary by product and model type:

ENPULSION NANO LARK

Flight hardware: 30 weeks typical (can be reduced to 24 weeks with an express fee)

Engineering or qualification models (EMs/EQMs): 24 weeks typical (can be reduced to 12 weeks with an express fee)

ENPULSION MICRO STARLING

Flight hardware: 30 weeks typical (can be reduced to 24 weeks with an express fee)

Engineering or qualification models (EMs/EQMs): 24 weeks typical (can be reduced to 12 weeks with an express fee)

Additional Notes:

ENPULSION lead times are significantly shorter than many other satellite propulsion systems, reflecting our streamlined production and in-house manufacturing capabilities

In select high-priority cases, ultra-accelerated lead times of one month or less may be possible; these are handled on a case-by-case basis and are not part of our standard offering

Larger or recurring orders may qualify for favorable terms, including reserved production slots, optimized delivery scheduling, or volume pricing based on planning visibility and contract structure
