A Minimal Four-Thruster System for Comet-Based Interstellar Navigation.

We propose a novel concept for interstellar navigation utilizing minimal modifications to naturally occurring interstellar comets. By equipping these comets with a compact four-thruster system, we demonstrate the feasibility of controlling their trajectories. This approach leverages existing cometary resources, such as volatiles for propellant, offering a highly efficient and sustainable method for deep-space and interstellar missions, potentially revolutionizing future exploration.
