This is Int-Ball.
No, it isn’t a flying BB-8. Int-Ball is the Japanese Space Agency’s (JAXA) grapefruit-sized camera drone deployed in the Japanese Experiment Module attached to the International Space Station. Its full name is JEM Internal Ball Camera. Int-Ball functions autonomously under the direction of ground crews at the JAXA Tsukuba Space Center. Its function is to record images and video for real-time viewing back on Earth. The device uses existing drone technology and its structure is made from 3D printed components.
JAXA estimates that 1-kilogram (2.2-pound) Int-Ball can replace nearly all of the onboard crew’s time spent recording images and video, which is approximately 10% of their total working time. It utilizes ultrasonic and inertial sensors, as well as image-based navigation to make its way between tasks. An array of twelve small fans allow the drone to maneuver in any direction, as well as to hold completely steady in the weightless environment.
A planned future version of the drone will perform additional monitoring tasks to free up even more astronaut working time.
