World's First Nuclear Fusion-Powered Electric Propulsion Drive Unveiled

An anonymous reader quotes a report from InterestingEngineering: A concept that began as a doodle at a conference years ago is now becoming a reality. RocketStar Inc. has showcased (PDF) its advanced nuclear-based propulsion technology called the FireStar Drive. It is said to be the world's first electric device for spacecraft propulsion boosted by nuclear fusion. Recently, the company announced the successful initial demonstration of this electric propulsion technology.

The FireStar Drive harnesses the power of nuclear fusion to improve the performance of RocketStar's 'water-fueled pulsed plasma thruster.' A spacecraft's thrusters perform various functions, including propulsion, orbital changes, and even docking with other orbiting platforms. Moreover, the device employs a unique sort of aneutronic nuclear fusion, which is a fusion reaction that generates few to no neutrons as a byproduct. 'The base thruster generates high-speed protons through the ionization of water vapor,' noted the press release. Therefore, these protons collide with the nucleus of a boron atom, which starts the fusion reaction. The FireStar Drive begins a fusion process by adding boron into the thruster exhaust, resulting in high-energy particles that increase thrust.

RocketStar's current thruster is dubbed M1.5. Plans to test the FireStar Drive are now ongoing. The in-space technological demonstration will take place aboard D-Orbit's patented OTV ION Satellite Carrier. The SpaceX Transporter rideshare mission will likely launch the demo test in July and October 2024. Furthermore, the team plans to undertake ground tests this year, with more in-space demonstrations scheduled for February 2025. The FireStar Drive will undergo testing as a payload aboard Rogue Space System's Barry-2 spacecraft in the same month. The thruster M1.5 is already ready for delivery to clients.
