full description at right Payload Specialist Jim Pawelczyk prepares to catch a ball as part of the ball catching (Kinelite) experiment. On Earth the ball would fall based on the acceleration of gravity, but in space the ball will be propelled toward the crewmember at a constant velocity

full description at right The kinelite, or catching, experiment is designed to look at how catching (representative of a stored complex motor response) changes in microgravity.

The electrodes that Dave Williams is wearing on his right arm allow recording of the muscle activity before and during the catching activity. He is also wearing a number of reflectors on my right arm, leg, and head so that the position of his body can be analyzed as well.

full description at right The Visuo-Motor Coordination Facility will be used to test the performance of the crew on various pointing, grasping, and tracking tasks. Here Mission Specialist Dave Williams practices tracking a moving target displayed on the screen of the device. The circle of light shows the track that he is making with his hand
