Fusion Propulsion Startups Target 2027 Orbital Tests to Revolutionize Solar System Travel

Multiple companies are advancing nuclear fusion propulsion for spacecraft, aiming to drastically reduce travel times across the solar system. Pulsar Fusion plans a 2027 orbital demonstration, while Princeton and Helicity Space are developing competing technologies. Experts warn that significant engineering challenges remain, but successful fusion drives could enable missions to Mars, Titan, and potentially interstellar destinations within decades.

Laser shocks revise diamond melting point, solving a decades-long discrepancy

Researchers used ultraviolet laser shock compression on tiny synthetic diamond plates, measuring changes in reflectivity and glow to map the diamond’s melting temperature with unprecedented precision. They found the melting point is more than 1,300°F (about 700°C) lower than previously thought, bringing it in line with theoretical predictions and resolving a long-standing gap between data and models. The findings have implications for nuclear fusion experiments that rely on diamond capsules and for understanding the interiors of ice giant planets like Uranus and Neptune, where diamond-like carbon behavior under extreme pressures may occur.

Trump Media posts $238M loss while doubling down on Truth Social and new ventures

Trump Media & Technology posted a $238 million loss in Q2 as it pivots back toward social media and expands into crypto and online betting under new CEO Kevin McGurn. It launched Truth API to sell early access to Truth Social posts to Wall Street traders for $60,000–$100,000 a month (10 customers) while continuing a nuclear-fusion venture with TAE Technologies; revenue rose 89% to $1.7 million, but the company carries about $1 billion in debt, with over $400 million in cash and roughly $1.2 billion in bitcoin.

Silver-Loaded Zeolites Enable Breakthrough Three-Isotope Separation for Fusion Fuel

German researchers have demonstrated silver-doped zeolites that selectively separate protium, deuterium and tritium—the three hydrogen isotopes—via interactions with silver ions in the crystal and staged release by heating. In tests, the output shifted to a 1:41:175 ratio (protium:deuterium:tritium), the first three-way separation of hydrogen isotopes in a solid porous material. This advances closed‑loop fuel recycling for commercial fusion and shows radiation tolerance, though long‑term operation remains under study.

Neon-Plasma Cleaning Boosts Fusion-Wall Purity to 87% In Situ

Researchers used neon plasma at 800°C inside a vacuum chamber to clean contaminated porous tungsten wall tiles inside a nuclear fusion reactor. The treatment removes bound carbon and oxygen and drives surface purity from 0% to 87% metallic tungsten, happening entirely within the reactor to avoid air exposure and preserve liquid-metal channels, a step that could streamline in-situ maintenance for future fusion power.

Materials-Driven Fusion: Metals Boost Low-Energy Nuclear Reactions

US researchers at UC Davis and Berkeley Lab found that surrounding host metals can dramatically boost low-energy deuterium fusion, with fusion rates plateauing below 2.5 keV and, in some samples, increasing by up to a quintillion-fold versus vacuum; the effect is attributed to electrons and structural defects in the host metal shielding Coulomb repulsion, opening a new materials-driven approach to fusion and potentially enabling compact neutron generators and new modeling tools like DuctGPT.

Polarization Persists in Laser-Plasma Acceleration, Boosting Fusion Prospects

Researchers have shown for the first time that the polarization (spin alignment) of particles is preserved during laser-plasma acceleration, a breakthrough for compact fusion research. Using pre-polarized Helium-3, the PHELIX laser, and CR-39 detectors, the team demonstrated that spin alignment survives high-gradient acceleration, which can increase fusion reaction probabilities and enable new physics experiments beyond the Standard Model.

HTS coil-winding breakthrough nudges fusion toward commercial power

Japan’s Helical Fusion has completed a one-of-a-kind coil manufacturing machine, built with Sugino Machine, to wind high-temperature superconducting cables into spiral coils for the Helix HARUKA reactor. The device targets a key manufacturing bottleneck to enable efficient production of HTS coils, a step toward commercially viable fusion energy by the 2030s, with on-site assembly to begin later this year and demonstrations planned around 2030 to prove net electricity, steady operation, and maintainability.
