The NASA planned 2028 nuclear powered ion drive spacecraft, SR-1 Freedom will have a 20 kilowatt nuclear reactor. SR-1 Freedom will use 20-plus kilowatt fission reactor fueled by High-Assay Low-Enriched Uranium and Uranium Dioxide, encased in a Boron Carbide Radiation Shield. This will power a xenon ion drive. Previous nuclear spacecraft designs involved more powerful …
Pulsar fusion is working to make a fusion propulsion system with about 10000-15000 ISP. This is about 25 to 40 times the ISP (exhaust speed and fuel efficiency) compared to chemical systems. There was a live demonstration during a technical session at Amazon’s MARS Conference in Ojai, California, presented by Pulsar Fusion CEO Richard Dinan. …
NASA will advance lunar science by affordably building out of the Moon Base and underpin future Moon and Mars exploration. An accelerated CLPS cadence, targeting up to 30 robotic landings starting in 2027. NASA is expediting delivery of science and technology to the lunar surface. There will be many opportunities for payload delivery including rovers, …
NASA will launch the Space Reactor‑1 Freedom, the first nuclear powered interplanetary spacecraft, to Mars before the end of 2028, demonstrating advanced nuclear electric propulsion in deep space. Nuclear electric propulsion provides an extraordinary capability for efficient mass transport in deep space and enables high power missions beyond Jupiter where solar arrays are not effective. …
Iran cannot use 60% enriched uranium directly in its current form (UF₆, which is stored as a solid in cylinders but handled as a gas or liquid during processing) to build a gun-type nuclear bomb. It must first be converted to metallic uranium, which is required for any fission weapon core. However, once converted they …
As of February 2026, NextBigFuture.com is one of the most heavily cited external sources on Grokipedia, with approximately 1,050–1,450 distinct Grokipedia pages containing direct links to NextBigFuture articles. This is roughly 10–13 times more than on English Wikipedia, which has ~110 citations. This high citation volume is concentrated in topics where NextBigFuture has provided long-term, …
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 …
XAI has created Grokipedia and Grokipedia has a Nextbigfuture article. Nextbigfuture provided early coverage of Companies that Become deep tech Unicorns. Dozens of top Nucleqr fission and Fusion, quantum computer and Space Companies before They Became Billion $ Unicorns. There has been a surge in Grokipedia traffic to approximately 3.5 million daily visits, representing a …
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 …
MIT Professor Nuno Loureiro was shot and killed two days ago. He lead the MIT Plasma Science Department and was working with Commonwealth fusion. Commonwealth Fusion is one of the leading nuclear fusion startups. Commonwealth Fusion Systems (CFS), a leading private fusion energy company spun out from MIT, has raised close to $3 billion in …
Oklo’s market capitalization has ballooned to $25 billion. The NRC denied Oklo’s custom combined license application in Jan 2022, citing insufficient information on maximum-credible-accident (MCA) analyses, safety classification of SSCs (systems/structures/components), QA implementation, and other key technical topics. The denial and associated letters are public. Oklo has since restructured its licensing approach and reengaged the …
