Answer
Gravity is required for both propioreceptors and the functioning of the semicircular canals. These both need gravity-driven physical contact between/among various parts for complete function. Astronauts would have some sense of relative movement of their body parts and could use their eyes to perceive motion, but the functioning of the sensory parts in the question would be partial at best.
Work Step by Step
Review the chapter on posture and on the sensation of angular acceleration. You will see how gravity is critical for fully functional operation of these senses.
