US Plans Nuclear Power in Space by 2031

• •OSTP outlines roles for NASA, DOE, and DOD in space nuclear power development.
• •Mid-power space reactors are targeted for launch by 2030, with a lunar variant required.
• •The initiative emphasizes inter-agency cooperation and potential private sector involvement.

The US Office of Science and Technology Policy (OSTP) released a memorandum outlining the roles of NASA, the Department of Energy (DOE), and the Department of Defense (DOD) in developing nuclear power for space missions. This initiative aims to establish low- to mid-power space reactors by 2031, with a focus on lunar and orbital applications. NASA is tasked with launching a mid-power reactor by 2030, while the DOD must analyze use cases for a mid-power reactor within 90 days, contingent on funding. The initiative reflects a renewed commitment to nuclear technology in space, building on previous plans from 2022 and 2025. The reactors are expected to provide essential power for lunar missions and future Mars exploration. The OSTP memo emphasizes inter-agency collaboration and the need for private industry involvement. The timeline for reactor deployment includes a goal of having fission surface power on the moon by 2030.
