This above part is the “SUDA Velocity Sensor Housing” machined by Peterson Machining.
This housing is a significant structural component of the SUDA “Sensor Head”. The “Sensor Head” lives on the exterior of the Europa Clipper Spacecraft. It measures the velocity and molecular composition of incoming “dust” particles that have been ejected off the surface of Europa (an icy moon of Jupiter). This “Velocity Sensor Housing” holds the components and electronics required to detect the incoming velocity of “dust” particles.
