I enjoyed talking through nuclear fusion propulsion with Douglas McAdams. We covered the latest developments and next steps for Pulsar Fusion’s Sunbird propulsion programme, including recent research and ongoing technical progress. The full discussion can be viewed in the recording below. PULSAR Balerion Space Ventures
Balerion Advisor Doug McAdams sits down with Richard Dinan, Founder & CEO of Pulsar Fusion, to discuss fusion propulsion.
We are looking forward to the Eye of the Dragon podcast with Balerion Space Ventures today. Richard Dinan will discuss the future of spacecraft propulsion and the ongoing development of Sunbird. 📅 May 19th | 1PM EST To register: b.savage@balerionspace.com Balerion Space Ventures

Our third 3m x 5m high-vacuum chamber arrived this week PULSAR This further expands our ability to qualify electric propulsion systems in parallel and move faster from development into production. Facilities like this matter as test infrastructure is often the bottleneck to enabling the British space ecosystem. Space #UKSpace #SpaceIndustry #ElectricPropulsion #SatellitePropulsion
We’re excited to be exhibiting at Space Symposium next week in Colorado Springs and showcasing our latest advancements in space propulsion. Our team on the ground: Susan McCarvell - Head of US Sales Ben K. – Propulsion Engineer Bilge Kacmaz – Research Engineer If you’re attending, we’d be delighted to connect, whether to discuss our technology, explore partnerships, or simply exchange ideas with others shaping the future of space. Feel free to reach out to arrange a time to meet. See you there! 🌟 📍 Colorado Springs 📆 April 13–16
A big thank you to the European Space Agency - ESA and Davina Di Cara for including PULSAR in the M-IND Electric Propulsion Interoperability Workshop, bringing together leading organisations across Europe to advance collaboration in in-space propulsion. James Lambert and Amy James attended and presented Pulsar's latest work in electric propulsion, highlighting the importance of interoperability, scalability, and rapid iteration as the space economy continues to evolve. Events like this are critical in aligning industry, agencies, and emerging technologies to ensure Europe remains at the forefront of advanced propulsion systems. We look forward to continuing the dialogue and building on the momentum created this week. #Space #SpaceTech #Propulsion #ElectricPropulsion #Aerospace #ESA
We are proud to share a first plasma demonstration achieved last week during a dedicated technical session at Amazon’s prestigious MARS Conference in Ojai, California, hosted by Jeff Bezos. The event brought together visionary leaders across machine learning, automation, robotics, and space. During a live presentation by our CEO, Richard Dinan, Pulsar Fusion achieved first plasma in our Mark I Sunbird exhaust test system, marking a significant early milestone in the programme. The experiment used a combination of electric and magnetic fields to guide and accelerate charged particles through the exhaust channel. For this initial test series, the propellant used was krypton, selected for its relatively high ionisation efficiency and inert characteristics at the mass flow rates required for early testing. In June 2026 Pulsar will introduce Langmuir probes and a Retarding Potential Analyser (RPA) to begin collecting detailed data on plasma behaviour, plume characteristics, and thermal loads within the system. Pulsar will then introduce rare earth, high temperature superconducting magnets, enabling stronger magnetic fields and allowing exploration of higher plasma density and pressure regimes. These tests are due to incorporate rotating magnetic field heating, RF heating systems, and a dedicated thrust balance to support more detailed performance measurements. The programme ultimately aims to begin experimental work with aneutronic fusion fuel cycles as part of the continued development of the Sunbird propulsion system. Pulsar will gather detailed performance data including thrust and exhaust velocity, using a thrust balance, E×B probes, and a Retarding Potential Analyser. This data will inform planning for the first Sunbird mission. To maximise the operational lifetime of Sunbird, Pulsar has also developed a research programme in collaboration with the UK Atomic Energy Authority (UKAEA). This work will study the effects of neutron radiation on reactor walls and magnets, a primary source of wear within fusion systems. Watch here: https://lnkd.in/ei8WiFWP
Thank you The Angry Astronaut, it’s voices like yours that genuinely encourage the team to keep pushing forward. Frontier technology doesn’t develop in isolation. It moves when an ecosystem pushes with it. Space agencies providing funding and validation. Investors backing longer-horizon ambition. Communicators who make complex ideas accessible. A public that leans in, not away. Thank you for helping explain our story simply, clarity matters in this industry. https://lnkd.in/ecJ7mD7M

This week I presented the Sunbird’s ‘first plasma’ live test at Amazon‘s MARS Conference in California, hosted by Jeff Bezos. In front of world-leading ML & robotics pioneers, Nobel laureates, and astronauts. I am very grateful to Jeff and the MARS team, it’s been a huge privilege ✨ Photo credit Ben Rose Ben Rose Photography.
