About
Benchmark’s Starling Ardent system incorporates a resistojet thruster, which is the culmination of design iterations from multiple NASA-funded programs. This development focused on maximizing efficiency and achieving a significant increase in specific impulse, doubling it from a typical 70s to 140s for gas systems. The resistojet technology is a key component of this system, offering enhanced performance for spacecraft propulsion.
