Pulsar Fusion

About Pulsar Fusion

Pulsar Fusion is a UK space propulsion company based in Bletchley that designs, builds and tests in-space engines for satellites and spacecraft. Its current products are Hall-effect thrusters, a type of electric plasma engine, offered in a range from the 500 W LEOBEAR through the 5 kW MOONRANGER to the 10 kW MARSRANGER, together with matching power processing and propellant management units. It has also developed and test-fired hybrid rocket engines.

Its customers are satellite operators, spacecraft manufacturers and in-orbit service providers that need efficient propulsion for station keeping, orbit raising, de-orbiting and precise manoeuvring. Pulsar earns money by selling and integrating its thruster systems, by renting out its large vacuum chambers and clean room for bespoke testing, and through development contracts with space agencies, universities and industry partners.

Its longer-term programme is Sunbird, a fusion propulsion concept built around a Dual Direct Fusion Drive that is meant to give interplanetary spacecraft both thrust and electrical power.
