Space Nuclear Power Corp (Spacenukes) is a leading company in the design and fabrication of fission reactor power systems for use in outer space. With a focus on powering missions to the Moon, Mars, and beyond, they specialize in developing practical and real reactors, as opposed to academic or paper designs. Led by a team of experts, their mission is to provide efficient and reliable power solutions for space exploration.

One of their notable achievements is the Kilopower Reactor Using Stirling Technology (KRUSTY) test, which demonstrated the successful operation of their reactor system under various conditions. The KRUSTY test showcased the reactor's ability to load-follow the demand of the power conversion system, with an overall system efficiency of approximately 25%. Looking ahead, Space Nuclear Power Corp envisions the use of their reactors for surface power applications on the Moon and Mars.

They have proposed a buried reactor configuration, reducing the mass of the landed system and allowing astronauts easier access for maintenance. Their power systems, with an initial unit power size between 10 and 30kWe, are designed to meet the power needs of future human settlements in space. Partnering with NASA and the NNSA, Space Nuclear Power Corp is at the forefront of advancing space reactor technology for the benefit of future space exploration endeavors
