Nuclear Rocket Design Emerges from a Napkin Sketch

A concept for a bimodal nuclear engine that could significantly reduce travel time to Mars was sketched out on a napkin by NASA engineer Kurt Polzin and General Atomics engineer Robert Schleicher. This idea, detailed in an IEEE Spectrum article, aims to combine mature technologies to create a more efficient and faster propulsion system for deep space missions.

The concept for a new nuclear rocket engine, capable of both powering and propelling a spacecraft, originated from a napkin sketch by Kurt Polzin, chief engineer of the space nuclear propulsion project at NASA’s Marshall Space Flight Center, and Robert Schleicher of General Atomics Electromagnetic Systems. This design aims to address the long travel times and radiation exposure inherent in interplanetary missions, particularly to Mars.

According to Stephen Cass, Special Projects Editor at IEEE Spectrum, the engine design merges mature technologies like electric propulsion with nuclear thermal propulsion. While electric propulsion is well-established, nuclear thermal propulsion is less developed, but past research provides a foundation. The novelty lies in combining these systems, which presents its own set of challenges.

Polzin and Schleicher believe their nuclear engines could cut the journey to Mars in half. The design is currently in the planning stages, awaiting further refinement and feedback. Cass likens this stage to much of NASA's Mars planning over the past decades, emphasizing that the core technologies are largely understood, but their integration is the key innovation.

The article, titled "A Reimagined Nuclear Rocket," was co-edited by Cass and illustrated by John MacNeill, moving the concept from a napkin to a published idea. IEEE Spectrum is soliciting feedback from the public on this concept, encouraging discussion and further development of the nuclear rocket engine design.
