The National Initiative for American Space Nuclear Power (NSTM-3) was recently announced as a collaborative effort between NASA and the Pentagon to advance nuclear power systems for future lunar and interplanetary missions. This initiative, which received formal endorsement from NASA, aims to develop the “SR-1 Freedom,” a 20-kilowatt electric space reactor intended for interplanetary propulsion and surface energy. Under the program guidelines, an in-orbit demonstration is expected by 2028, with a functional reactor projected for deployment on the lunar surface by 2030.
This collaboration reflects a broader strategy endorsed by the Trump administration, emphasizing reliable energy sources for deep-space exploration and defense applications. Following this announcement, investors showed significant interest, leading to notable stock increases for companies involved in small modular reactors. Oklo’s shares rose over 26%, and NuScale’s stocks climbed nearly 20% within the week. Oklo focuses on microreactors suitable for remote areas, aligning well with NASA’s vision for off-Earth energy solutions, while NuScale is the only U.S. firm with an NRC-approved small modular reactor design, enhancing its potential as a government partner in upcoming projects.
The NSTM-3 initiative represents a significant intersection of civilian space exploration and defense energy research, opening new avenues for investment in microreactor and nuclear propulsion technology. As the U.S. aims for sustainable operations on the Moon and beyond, nuclear energy is becoming increasingly critical to achieving those objectives, and investor enthusiasm is already evident.
