From Deep Space "Nuclear Batteries" to Extraterrestrial Nuclear Propulsion: How Nuclear Technology Is Reshaping the New Paradigm of Future Space Exploration

As deep space exploration, the construction of permanent lunar research stations, and crewed Mars missions gradually move onto the international space agenda, human spaceflight technology is facing unprecedented energy and propulsion bottlenecks. The International Atomic Energy Agency (IAEA) recently reviewed and outlined the key role and development trajectory of nuclear technology in space exploration. From the radioisotope thermoelectric generators that quietly served in the Apollo program more than half a century ago, to the efficient micro nuclear fission reactors currently undergoing ground testing, to nuclear propulsion systems expected to cut interplanetary flight times by more than half, space nuclear power technology is evolving from a marginal auxiliary energy source into a strategic core power for deep space exploration....

Centrus Energy to Supply HALEU Fuel to Antares Nuclear, Enabling Micro Nuclear Reactor Applications for Military and Space

U.S. nuclear fuel supplier Centrus Energy has signed a multi-year contract with advanced microreactor developer Antares Nuclear, under which Centrus will supply high-assay low-enriched uranium (HALEU) to Antares. This agreement is expected to expand the application scenarios of micro nuclear reactors to locations where traditional power sources are difficult to use, such as military facilities and space environments. As part of the agreement, Antares Nuclear will make advance payments to support Centrus in expanding HALEU production capacity in the United States. Compared with conventional low-enriched uranium, HALEU contains more uranium-235, with an enrichment level above 5% but below 20%. This new type of fuel can support smaller, higher-energy-density reac...

U.S. ZC Institute Unveils "Kardashev One" Fusion Prototype Reactor Plan to Independently Test Neutron Recovery Concept

ZC Institute, a fusion energy company headquartered in Atlanta, USA, announced on September 4 the launch of the Kardashev One program, aiming to develop a fusion prototype reactor to explore recovering energy lost to radiation and neutron escape during fusion reactions. As an early validation step of the program, ZC Institute has commissioned Professor Jason Cassibry and his team at the University of Alabama in Huntsville (UAH) to conduct independent testing of the related field distortion technology. According to ZC Institute, existing fusion approaches, including inertial confinement fusion and magnetic confinement fusion, lose energy in forms such as electromagnetic radiation and neutron escape. Magnetic fields can confine charged...

Auburn University Installs 200 MeV Superconducting Proton Accelerator to Build First University-Led Space Electronics Radiation Testing Facility in the U.S.

Auburn University's Applied Research Institute has announced the installation of a new 200 MeV superconducting proton accelerator, advancing the construction of the nation's first university-led proton testing facility dedicated to space electronics qualification. The system, a RAD-FX-200 superconducting synchrocyclotron manufactured and installed by Mevion Medical Systems, serves as the core component of Auburn University's new radiation-hardening facility. According to reports, the facility will help address gaps in U.S. space qualification testing capacity, providing radiation testing services for microelectronics to government agencies, aerospace, and defense-related industries. Systems such as satellites, missile defense interceptors, spacecraft, and launch vehicles rely on microelectronics, which may be affected by proton radiation in orbital environments. A single radiation-induced failure can cause system loss, and such failures are typically difficult to repair once in orbit...

Europe Advances Space Nuclear Power Research, Targeting Lunar and Mars Missions

The European Space Agency (ESA) is accelerating its assessment of nuclear energy applications in deep-space missions, focusing on using small nuclear reactors to power spacecraft electric propulsion systems, as well as providing stable energy for future fixed lunar surface facilities and subsequent Mars missions. Existing space missions primarily rely on chemical fuels and solar panels. The former is limited by the amount of propellant that can be carried, while the latter suffers from declining power generation efficiency as spacecraft move farther from the Sun. ESA believes that nuclear power systems could compensate for the shortcomings of both approaches, particularly in long-duration lunar operations and deeper space exploration. ESA completed a nuclear thermal propulsion study last year. In March this year, the agency...
