About
The Halcyon High-Test Peroxide (HTP) propulsion systems provide high-thrust chemical propulsion for various space missions. The Halcyon monopropellant thruster offers 1-10 N of thrust per thruster and a specific impulse of 155-160 seconds. For higher performance, the Halcyon Avant bipropellant thruster delivers 20 N of thrust per thruster with a specific impulse of 270-280 seconds. These systems are suitable for mission applications such as In-Space Servicing, Assembly, and Manufacturing (ISAM), high Delta-V maneuvers, high-thrust operations, and reentry support. Benchmark Space Systems has enabled 14 missions, built over 150 thrusters, and accumulated more than 160,000 seconds of hotfire testing with their HTP technology.
