SPHERES Tether Slosh

iss055e010694 (4/4/2018) --- A view taken aboard the International Space Station (ISS) during the set up of the SPHERES Tether Slosh experiment hardware. The image is of the green 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. SPHERES Tether Slosh combines fluid dynamics equipment with robotic capabilities aboard the International Space Station to investigate automated strategies for steering passive cargo that contain fluids.
