Pulsar Fusion is advancing electric propulsion technology through a portfolio of Hall Effect Thrusters (HETs) designed to improve spacecraft efficiency, extend mission lifetimes and reduce operational costs. Intended for applications including attitude control, precision spacecraft control and low-thrust manoeuvres, the company's plasma thrusters utilize high specific impulse (Isp) technology to deliver greater fuel efficiency than conventional propulsion systems. This enables satellites to perform drag compensation, extend orbital lifetimes and reduce the frequency of replacement launches required to maintain space infrastructure.

The company's Hall Effect Thruster family includes three propulsion systems tailored to different mission requirements. LEOBEAR is a 500 W thruster developed for small spacecraft, Moonranger is a 5 kW system for higher-power missions and Marsranger is a 10 kW propulsion system designed for demanding in-space operations. Together, these thrusters provide scalable electric propulsion solutions across a broad range of spacecraft sizes and mission profiles.
LEOBEAR operates at 300–500 W with input voltages between 300 and 400 V, producing 12–33 mN of thrust and a specific impulse of 1300–2500 seconds. Moonranger operates between 5 and 7.5 kW, delivering 280–350 mN of thrust with a specific impulse of 1800–2010 seconds, while Marsranger operates at 5.6–10.2 kW, generating 605–690 mN of thrust and achieving a specific impulse of 2000–2200 seconds. The propulsion systems are designed to deliver progressively higher thrust while maintaining the fuel efficiency advantages associated with Hall Effect propulsion.

The thrusters are engineered with compact architectures suitable for modern spacecraft integration. LEOBEAR has an assembly mass of 2.7 kg, while Moonranger and Marsranger weigh 13.77 kg and 20.61 kg, respectively. The propulsion systems are designed to support efficient spacecraft manoeuvring while minimizing mass and volume, making them suitable for satellites operating across low Earth orbit and other in-space missions.

To ensure operational reliability, Pulsar Fusion tests its Hall Effect Thrusters at a UK government facility where the propulsion systems are evaluated for launch survivability and compliance with industry standards. By combining high specific impulse performance with rigorous qualification testing, the company aims to deliver electric propulsion systems capable of supporting long-duration missions and improving spacecraft operational efficiency.
Through its portfolio of scalable Hall Effect Thrusters, Pulsar Fusion is developing electric propulsion technologies that provide efficient in-space manoeuvring, precision orbital control and extended satellite lifetimes. The company's electric propulsion systems are designed to support commercial and institutional spacecraft operators seeking higher mission performance, lower operating costs and more sustainable long-term space operations.
