Seeking spacecraft that can “maneuver without regret,” the U.S. Space Force is investing $35 million in a national research team led by the University of Michigan to develop a spacecraft with an onboard microreactor to produce electricity, with some of that electricity used for propulsion. But this spacecraft would not be solely dependent on nuclear electric propulsion—it would also feature a conventional chemical rocket to increase thrust when needed.

The most important thing the nuclear community can do to support space nuclear applications is the same thing we must focus on for terrestrial nuclear science: developing the trust of the American public.

Americans are widely supportive of NASA, and space has long captivated our imaginations. Recently, the publicity surrounding the new U.S. Space Force and the popularity of commercial rocket launches have drawn the public eye skyward. We don’t need to convince people that space is important and exciting, but we do have a long way to go in promoting nuclear power to the public.
