DeltaX Propulsion

DeltaX Propulsion is a U.S. company building advanced electrospray thrusters and related space technologies by translating breakthroughs in nanomaterials science into reliable in-space propulsion systems. The company's electric propulsion systems combine efficiency, scalability, and lightweight design to power the next era of small satellites and spacecraft, enabling agile maneuvering, formation flying, and longer mission lifetimes.

DeltaX's electrospray thrusters deliver a specific impulse (Isp) of approximately 3,000 seconds — two to three times that of chemical thrusters — while achieving a 50% mass reduction through aerogel-integrated propellant. The propulsion systems feature modular, scalable design suitable for platforms ranging from CubeSats to GEO-class spacecraft, with precision thrust control and lower power consumption than competing electric alternatives.

Beyond space propulsion, DeltaX applies its nanomaterials and electrospray expertise to materials science research and services, including EMI shielding (DeltaX Barrier), thermal barrier coatings (DeltaX Shield), and electrospray coating services (DeltaX SprayLab) for industrial and defense applications.
