Commissioning of the CRAFT Cryogenic System 6 kW@4.5 K Helium Refrigerator Successfully Completed

Recently, significant progress has been made in the construction of the helium refrigeration system on the CRAFT magnet platform. The on-site commissioning and performance testing of the main body of the CRAFT cryogenic system 6 kW@4.5 K helium refrigerator have been successfully completed, with all indicators meeting the design acceptance requirements. The commissioning work focused on systematic verification of the cold box refrigeration performance, liquefaction capacity, control system, safety interlocks, and the operating status of key cryogenic equipment. During the acceptance tests, the helium refrigerator completed 12 hours of continuous stable operation under design conditions, achieving a refrigeration capacity of 6 kW@4.5 K + 50 K@GHe. In addition to design conditions, the project team also conducted performance tests under helium liquefaction conditions, with relevant temperature, pressure,...

U.S. Plans to Launch Nuclear Fission-Powered Spacecraft to Fly by Mars by End of 2028

The National Aeronautics and Space Administration (NASA) is advancing the Space Reactor-1 "Freedom" (SR-1 Freedom) mission, with the goal of launching a nuclear fission-powered spacecraft by the end of 2028 to validate deep-space nuclear electric propulsion technology. According to existing mission documentation, the mission plans to fly by Mars in 2029 and deploy the SkyFall payload. The SR-1 Freedom is neither a fusion spacecraft nor a crewed Mars vehicle. Its core experiment is to operate a small uranium fission reactor, an energy conversion system, and Hall-effect thrusters in coordination beyond Earth orbit, accumulating engineering data for future higher-power deep-space missions...

Nuclear-Powered Aircraft Carrier USS John F. Kennedy Completes Acceptance Sea Trials

Huntington Ingalls Industries (HII) announced on August 15 that its subsidiary Newport News Shipbuilding (NNS) has successfully completed acceptance sea trials for the second Gerald R. Ford-class nuclear-powered aircraft carrier, USS John F. Kennedy (CVN 79). USS John F. Kennedy conducted further testing and evaluation of critical ship systems and components at sea before returning to Newport News Shipbuilding. Earlier this year, the carrier had completed builder's sea trials. Derek Murphy, NNS vice president in charge of the new carrier construction program, stated that the carrier...

Russia's Bion-M 3 spacecraft planned for launch in 2030 to study effects of cosmic radiation on living organisms

Russia plans to launch the new Bion-M 3 spacecraft in 2030 to study the effects of cosmic radiation on living organisms under conditions similar to deep space. Vladimir Sychev, a senior official at the Institute of Biomedical Problems of the Russian Academy of Sciences, presented the plan at a meeting of the Presidium of the Russian Academy of Sciences' Space Council on August 4. Sychev stated that cosmic rays, solar proton events, and their effects on the human body are critical issues that must be understood when planning long-term interplanetary crewed missions. Participants have endorsed the draft scientific research program for the spacecraft's flight testing. According to the plan, Bion-M 3 will be placed into a polar orbit at an altitude of approximately 800 kilometers...

South Korea Advances K-Moonshot Initiative, Nuclear Fusion and SMR Spacecraft Listed as Key Missions

The South Korean government is accelerating the K-Moonshot initiative, seeking to tackle critical technologies that are difficult to break through via traditional research pathways through a national-level R&D organizational approach. Among these, nuclear fusion and small modular reactor (SMR) spacecraft have been included in 12 key missions, alongside new drug development, quantum technology, and artificial intelligence, all under the government's coordinated promotion. On August 10, Vice Minister Goo Hyuk-chae of the Ministry of Science and ICT (MSIT) met with the heads of the 12 mission projects and representatives of related institutions at the K-Moonshot Project Support Office in Sejong City to discuss next-stage implementation arrangements. The meeting focused on detailing...

US BWXT in Discussions with Naval Reactors on Proposed Nuclear-Powered Warship Reactor Design

BWX Technologies is in preliminary discussions with the U.S. Naval Reactors program regarding a proposed nuclear-powered warship. According to company CEO Rex Geveden during the Q2 2026 earnings call, the project could begin long-lead procurement as early as 2028 if approved and funded by the U.S. Congress. Image credit: U.S. Navy. Geveden stated that the design could leverage the existing reactor design used in Ford-class aircraft carriers. Each Ford-class carrier is equipped with two large reactors, while the proposed warship could use one reactor of the same type. Given BWXT's existing naval propulsion systems business, this approach aligns directly with the company's current manufacturing capabilities...
