iss054e022175 (1/17/2018) --- Japan Aerospace Exploration Agency (JAXA) astronaut Norishige Kanai is photographed during a Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) Tether Slosh experiment test session run.

SPHERES Tether Slosh combines fluid dynamics equipment with robotic capabilities aboard the ISS to investigate automated strategies for steering passive cargo that contain fluids. In space, the fluid fuels used by spacecraft can slosh around in unpredictable ways making space maneuvers difficult. SPHERES Tether Slosh uses two Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) robots tethered to a fluid-filled container covered in sensors to test strategies for safely steering spacecraft such as dead satellites that might still have fuel in the tank.
