Fusion Propulsion

Designed to produce both thrust and electric power for interplanetary spacecraft. Long-term source of acceleration with self-sustaining fuel supply.

Pulsar Fusion is presently committed to the construction of its initial prototype static fusion rocket engine. After completing a State of the Art (SoA) assessment on heating technology in 2021, further analysis was carried out by a panel of experts to finally make an informed decision on an initial design point for the system.

Pulsar has now proceeded to phase 3, the manufacture of the initial test unit. Static tests are to begin in 2024 followed by an In Orbit Demonstration (IOD) of the technology in 2027.
