Industry Update—December 2025
Here is a recap of recent industry happenings:
Agreement signed on advanced nuclear technology in space
Texas-based space technology and orbital logistics developer Space Ocean Corporation and New Mexico–based space nuclear power systems developer Space Nuclear Power Corporation (SpaceNukes) have signed a letter of intent to explore the integration of advanced nuclear reactor technology into future space missions. Space Ocean agreed to test SpaceNukes’ 10-kilowatt microreactor aboard its ALV-N satellite and, if performance criteria are met, to use SpaceNukes as a core supplier of reactors for future Space Ocean lunar and planetary missions. The companies also agreed to examine the integration of fluid delivery systems with reactor modules, to collect operational data to support technology readiness certification, and to form a joint working group to pursue additional space infrastructure and commercial opportunities.
