The Canfield Joint is an innovative prototypical  joint that offers hemispherical pointing control. Spacecraft traditionally use stationary thrusters for stationkeeping, and are life-limited by propellant storage capacity. A thruster mounted on the Canfield Joint would enable capability of multiple thrust vectors, reducing propellant and hardware costs.

     Solar panels mounted on the joint could also allow for continuous power generation during spacecraft maneuvers. In many cases, spacecraft are rolled during flight to evenly distribute the thermal effects of solar heating. During this process, solar panels with traditional mounts experience "blind spots." The Canfield Joint allows a solar panel to track the sun during such maneuvers, greatly optimizing power generation.
