The UK Space Agency is funding two nuclear projects as part of the second phase of investment awarded through its £20m ($25m) International Bilateral Fund (IBF). Rolls-Royce and BWXT receive £1.18m for their collaboration on fission nuclear systems for space power missions. The University of Leicester and its international partners receive more than £783,000 to identify a range of mission opportunities for UK space nuclear power technologies. The collaboration also includes the development of hybrid power systems with existing US conversion technologies.

The US Department of Energy (DOE) has shipped 0.5 kilograms of heat source plutonium oxide from Oak Ridge National Laboratory (ORNL) to Los Alamos National Laboratory (LANL). It will support future NASA deep space missions that rely on radioisotope power systems, such as the upcoming Dragonfly mission. Dragonfly will be powered by a radioisotope power system called a Multi-Mission Radioisotope Thermoelectric Generator.
