What's Happening?
Zeno Power, a U.S. startup, has signed a multimillion-dollar agreement with Orano, a French nuclear recycler, to secure a steady supply of americium-241 (Am-241) for its long-duration space batteries. This deal provides Zeno with priority access to material recovered from used nuclear fuel in France, addressing the scarcity of plutonium-238 (Pu-238) that has traditionally powered NASA's deep space missions. The company is developing americium-fueled nuclear batteries, or radioisotope power systems (RPS), to support NASA's lunar and Mars missions. Am-241 is favored for its long half-life of over 430 years, enabling power systems to operate for decades.
Why It's Important?
The agreement marks a significant step in ensuring the sustainability of space missions, particularly those under NASA's Artemis and Moon-to-Mars programs. By utilizing Am-241, Zeno Power can conserve the limited Pu-238 supplies for flagship missions, potentially reducing costs and increasing the feasibility of long-term space exploration. This development could enhance the U.S.'s capabilities in space technology and exploration, providing a reliable power source for lunar rovers and infrastructure. The move also highlights the growing importance of nuclear power in space exploration, offering a solution to the challenges posed by the lunar night and the need for long-lasting energy sources.
What's Next?
Zeno Power plans to fly an americium-fueled radioisotope power system by the end of the decade. The company is working with the Federal Aviation Administration and other agencies to establish regulatory pathways for its plans, expecting commercial missions to be approved within 12-24 months from launch vehicle selection. Additionally, Zeno is developing strontium-fueled batteries for maritime-focused missions under a Department of Defense contract, indicating a broader application of its nuclear power technology beyond space exploration.
