Fig. 9: The motion devices used for simulating a post-spaceflight water landing.

The centrifuge (a, b) rotated at 24 RPM to generate a net 2 g’s at the head while the sled (c, d) produced roll tilts and lateral translations at the frequencies of an ocean buoy. Note that the curvature in the track in (c) is a result of a fisheye lens. The track is straight.
