UK-based Pulsar Fusion announced it has successfully achieved first plasma in its Sunbird nuclear fusion rocket exhaust system. The demonstration, a world’s first for a rocket of this type, was showcased live during a technical session at Jeff Bezos’s exclusive MARS Conference in California, offering a tantalizing glimpse into a future of dramatically faster interplanetary …
Helion’s Polaris prototype has become the first privately funded machine to demonstrate clearly measurable deuterium–tritium (D‑T) fusion and to reach 150 million °C plasma temperatures, marking a major but still early milestone on their path toward a commercial generator for the Microsoft PPA around 2028. Helion reports that its 7th prototype, Polaris, has achieved measurable …
Trump Media & Technology Group (TMTG), the parent company of Truth Social and ticker DJT, has announced a definitive agreement to merge with TAE Technologies, a leading private nuclear fusion energy company, in an all-stock transaction valued at more than $6 billion.Key details of the merger:This creates one of the world’s first publicly traded nuclear …
NASA NIAC has funded studying the development of a constellation of spacecraft powered by the Helicity Drive, a compact and scalable fusion propulsion system. In April 2, 2024 – Helicity Space had an investment from Lockheed Martin Ventures, the venture capital arm of Lockheed Martin. This was after a $5 million seed round of Helicity …
Pulsar UK has signed an agreement with Thales Alenia Space (TAS) for the Pulsar’s 5kW MOONRANGER Hall-effect thrusters, which are being live test-fired. Pulsar Fusion, the UK-based fusion propulsion company behind the breakthrough Sunbird platform, is opening a new U.S. office in Austin, Texas. This strategic move supports Pulsar’s increasing engagement with U.S.-based clients and …
In April 2025, Lawrence Livermore National lab (LLNL) had its eighth successful ignition experiment and set another record for energy yield, delivering 8.6 MJ from 2.08 MJ of energy to the target and further demonstrating that NIF can repeatedly conduct fusion experiments at multi-megajoule levels of energy output. They got over four times the energy …
The Startup Pulsar Fusion is proposing a 2 Megawatt nuclear fusion orbital components for 2027. Pulsar has now proceeded to phase 3, the manufacture of the initial test unit. Static tests are to begin in 2025 followed by an In Orbit Demonstration (IOD) of the core technology components in 2027. With Sunbird in Orbit: A …
Centrifugal Magnetic Mirrors could enable commercial nuclear fusion reactors on Earth and are also promising for next level propulsion in space. There is funded near term work for both goals. An early Centrifugal Magnetic Mirror propulsion concept could achieve 1 to 10 newtons of thrust with 10,000 to 30000 ISP. This would be propulsion that …
Aligning the quantum property known as spin for fusion fuels could make it easier to generate electricity economically. Above – An artist’s interpretation of spin-aligned atoms during the process of fusion. (Illustration credit: Kyle Palmer / PPPL Communications Department) A different mix of fuels with enhanced properties could overcome some of the major barriers to …
Ohysicists at the University of Wisconsin–Madison produced a tokamak plasma that is stable at 10 times the [old] Greenwald limit. The findings may have implications for tokamak fusion reactors, though the researchers caution that their plasma is not directly comparable to that in a fusion reactor. Nearly 40 years ago, Martin Greenwald identified a density …
Nuclear fusion startup, Fuse, is trying to make a mass production version nuclear fusion system based upon the Sandia Z Machine. This is magnetized target fusion using Marx generators. They leverage the Z pinch for their pulsed power approach. They are making a 1-Terawatt TITAN machine and plan to build Z STAR which aims to …
