RocketStar Announces Successful Demonstration of Fusion-Enhanced Pulsed Plasma Electric Propulsion

Innovator of in-space propulsion and digital signal processing creates the world’s first electric propulsion device enhanced with nuclear fusion

NEW YORK, March 20, 2024 (GLOBE NEWSWIRE) -- RocketStar Inc. has successfully demonstrated the FireStar Drive, a groundbreaking electric propulsion unit for spacecraft that uses nuclear fusion-enhanced pulsed plasma. This innovative device significantly boosts the performance of RocketStar's base water-fueled pulsed plasma thruster by utilizing a unique form of aneutronic nuclear fusion. The base thruster generates high-speed protons through the ionization of water vapor. When these protons collide with the nucleus of a boron atom, the atom undergoes fusion, transforming into a high-energy form of carbon that rapidly decays into three alpha particles. By introducing boron into the thruster's exhaust, the FireStar Drive enables this fusion process. Similar to the way an afterburner enhances thrust in a jet engine by introducing fuel into the exhaust, the fusion occurring in the thruster's exhaust significantly improves its performance.

The fusion discovery was first made during an SBIR Phase 1 for AFWERX where boronated water was introduced into the pulsed plasma thruster’s exhaust plume. This created alpha particles and gamma rays, clear indications of nuclear fusion. It was further validated during the subsequent SBIR Phase 2, where at Georgia Tech's High Power Electric Propulsion Laboratory (HPEPL) in Atlanta, Georgia it not only created the ionizing radiation but also improved the base propulsion unit’s thrust by 50%.

“RocketStar has not just incrementally improved a propulsion system, but has taken a leap forward by applying a novel concept, creating a fusion-fission reaction in the exhaust,” said Adam Hecht, Professor of Nuclear Engineering at the University of New Mexico. “This is an exciting time in technology development, and I am looking forward to their future innovations.”

“We are thrilled at the results of our initial testing on an idea that our team has been exploring for some time,” said Chris Craddock, CEO of RocketStar. “On a napkin at a conference in Florida, I sketched this idea out and described it to Wes Faler, the founder of Miles Space. He was quite clever in developing both the base thruster and the fusion enhancement. We acquired Miles Space and Faler is now our CTO. So now I’m excited to take our already stellar thruster and make it fusion-enhanced with remarkable improvements in performance. Thanks to AFWERX and the USSF for believing it was possible!”

Next Steps
RocketStar’s current thruster is now available for delivery to customers. It’s called the M1.5 and will be demonstrated in space as a hosted payload on D-Orbit’s proprietary OTV ION Satellite Carrier which will go on two SpaceX Transporter missions scheduled for July and October of this year.

“We are very happy to have the opportunity to work alongside RocketStar and contribute to the demonstration of the M1.5,” said Matteo Lorenzoni, Head of Sales at D-Orbit. “We just integrated the thruster onto the ION Satellite Carrier, and look forward to witnessing its performance in orbit.”

Plans to test the FireStar Drive include further ground testing this year with an in-space demonstration scheduled for February 2025 as a hosted payload on Rogue Space System’s Barry-2 spacecraft. “We are very excited to test FireStar for RocketStar,” said Brent Abbott, CRO at Rogue Space Systems. “We look forward to considering it for future Rogue missions.”
