Earlier today, Zeno Power announced the completion of the final design review for an americium-241–fueled radioisotope power system (RPS) developed for Harmonia RPS, a NASA Artemis Tipping Point project.

The Harmonia RPS project will now begin the build and fabrication phase. Zeno plans to complete a terrestrial demonstration of an electrically heated system in early 2027 and is aiming for flight qualification for lunar missions beginning in 2028.

The University of Missouri Research Reactor (MURR) has commenced production of gadolinium-153, a radioisotope used in medical imaging applications, as announced by the Department of Energy’s Office of Isotope R&D Production (IRP) and the university earlier this week. That makes MURR the only domestic supplier of Gd-153 and one of two suppliers in the world.
