Satellite electric propulsion is enabling a revolution in space mobility. With new radiation-tolerant thrusters, advances in miniaturization, and increased mission lifespans, operators and manufacturers worldwide are leveraging breakthroughs to make both advanced and small satellites more versatile, reliable, and sustainable. From interplanetary maneuvers to mega-constellation management, recent collaborations and technology unveilings point to rapid transformation across the sector.
According to Straits Research, the global satellite electric propulsion market size was valued at USD 589.21 million in 2024 and is projected to grow from USD 613.37 million in 2025 to USD 845.91 million by 2033, growing at a CAGR of 4.10% during the forecast period (2025–2033). The integration of electric propulsion solutions is driven by satellite operators’ need for lower mass, extended lifetime, reduced fuel costs, and enhanced maneuverability—features increasingly critical in the crowded low Earth orbit.
Breakthroughs in Electric Propulsion Technology
Major developments in the past year highlight the sector’s accelerating pace. Enpulsion (Austria) unveiled the Nexus propulsion system in May 2025, boosting thrust for satellites up to 500 kg and improving orbit-raising ability using innovative FEEP technology. This system addresses the industry’s demand for high performance in small satellite missions and is positioned as a compelling alternative to conventional Hall Effect Thrusters for various platforms.
ISRO (India) has achieved a milestone with the successful completion of a 1,000-hour life test for its 300 milliNewton Stationary Plasma Thruster (SPT), taking strides toward all-electric satellite launches and increasing payload capacity. This advance is part of a broader shift that promises efficient orbit-raising, station keeping, and eventual deep space maneuvers leveraging xenon-fueled, high-specific-impulse thrusters.
In April 2025, IHI Corporation (Japan) finished in-orbit testing of its chemical-electric hybrid propulsion system, paving the way for more versatile and cost-effective mission architectures for Japanese satellites. Europe remains at the forefront, with Airbus (Netherlands) delivering all-electric propulsion platforms to minimize launch weight and maximize operational flexibility.
