The Defense Innovation Unit (DIU) has announced a call for industry proposals focusing on advanced spacecraft propulsion technology, specifically emphasizing electrospray thrusters.

Electrospray thrusters, which generate thrust by accelerating charged particles, offer significant advantages in terms of fuel efficiency and precise control. This innovative technology aligns with the DoD's increasing reliance on smaller satellites for communications and intelligence gathering.

Traditional propulsion systems based on liquid or gaseous propellants often face limitations, as fuel conservation is crucial for critical maneuvers. Electrospray technology presents a solution by allowing spacecraft to perform more frequent and precise adjustments without depleting fuel reserves. This enhanced maneuverability is critical for a range of space missions.

"The Department of Defense is seeking proposals for advanced electrospray propulsion technology that demonstrates superior performance in both thrust and specific impulse," DIU stated. "These solutions should deliver a high-performance, low-cost system capable of supporting a wide range of space missions."

DIU is a DoD organization committed to integrating commercial technologies for national security purposes. It awards prototype contracts to companies showcasing promising technologies that address specific DoD requirements.

Several commercial companies are actively engaged in developing electrospray thruster technology, including Boston-based Revolution Space (formerly known as Accion Systems), Spanish small satellite propulsion developer Ienai Space, and Ion-X of France. The advancement of this technology promises to revolutionize spacecraft propulsion, enhancing capabilities and enabling a wider range of space missions.
