# Field Propulsion

Propulsion systems using electromagnetic fields to reduce or eliminate onboard propellant mass
- Technology Readiness Level: 5/9
- Impact: 5/5
- Investment: 4/5
Field propulsion encompasses electrodynamic tethers, electrodeless plasma thrusters, and related concepts that reduce propellant mass. Varies by subtype; some in production, some theoretical. Applications: orbital maneuvering, long-duration interplanetary missions. Benefits: reduced propellant; extended mission range.
