The Bradford Space Comet 1000 is a medium-thrust, medium-Isp thruster assembly optimized for orbital maintenance needs of satellites in the 10 to 50 kg range. It offers a simple way to add a strong propulsive capability to large Cubesats and microsats.
By seamlessly integrating a water tank with a thruster assembly and essential control systems, the Comet-1000 offers a plug & play propulsion unit, simplifying deployment and operation. Its utilization of low-pressure water as propellant ensures safe integration, shipping, launch, and operation, without imposing burdensome handling precautions.
With its impulsive thrust and low power consumption, the Comet range facilitates swift orbit maintenance or adjustments, minimizing disruptions to revenue-generating payload operations. As the pioneer in water thruster technology, Comet took flight in 2018, and today boasts the most water thrusters in space, with years of accumulated on-orbit experience.
